Maxxecu Review - Is it good?

Today we review the Maxxecu Race Premium kit that we installed on my Turbo Ameri-Barra Vortec 4200 Inline 6 powered 1981 Ford Fairmont Station Wagon. The IO capability with the Maxxecu is incredible and will help us greatly for the Drag Racing Season. The Analog Inputs, Digital Inputs, EGT inputs, and advanced Traction Control, Self Learning, and advanced CAN bus capabilities are awesome!! If you are looking for an ECU for any form of motorsports, drifting, road racing, autocross, drag racing, this is a great option!
Thanks for watching!!

Great review and info 👍👍

[@802Garage]

My friend just bought one of these and I knew next to nothing about the brand. Wow that IO adaptability is awesome. I've often wondered why other brands aren't more permissive. Other than to limit features between models of course. As a programmer, I def appreciated the part about being designed by an engineer, hahaha. I think most aftermarket ECU options obviously are, but that doesn't mean there aren't big differences in approaches and who made the final calls. Great overview!

[@brandonbeneficial6160]

I have never tuned anything nor am I at the step in my build where I need to do so and STILL this is some of the most valuable information ever. Not to mention the review is courtesy of someone who is competent, has ACTUALLY put these products through their paces, and isn't biased due to some sponsorship. Thanks Nivlac57

Thanks for the MaxxECU review. Purchased the Maxx Mtune mini for my Triumph, I'm new to this (Have been using 2x40dcoe 151Weber's) EFI so far looks great. it is a bit of learning curve, but fun.

[@forced4motorsports]

Thanks Calvin. I now have a firm answer as to what I'm going to use on my Ford 4.0 V6. I was decided on Holley until now but this seems like a much better option for a 6 cylinder.

[@_the_Chad_]

Excellent video! I'm definitely a belly button combo guy but I got a lot out of this. I like everything about my Raspberry pi dash except the boot time. 3 seconds to run on the Tinker Dash is amazing.

[@Calvin-Nelson]

Thanks! Yeah. I've tried raspberry pi dashes in the past. I got annoyed with having to hit "ok" as soon as the tune on the box got out of sync with the tune on the dash. Glad it works good for you.

[@supercuda1950]

Thanks for all the technical info and taking the time to explain different terms related to tuning this engine (or any other). Your explaination keeps the newby from buying a product that may not be exactly what we want. Also, in a previous reply I mentioned the supply of the 4200 Vortec drying up. Now that I know what vehicle they come in, the supply, though not endless, is prety healthy. Again, thanks for this excellent video. By the way, How's Dad doing?

Right on man ! See, this is why its worth going above and beyond to do some R'n'D on under exposed systems like this for different applications. Getting to work hand in hand with companies to make products better. I have done the android digital dash but only with the torque app which does not give me any issues. I dont mind clicking an "ok" button on a free app but would like to try this first hand

[@Calvin-Nelson]

Yeah. When you are strapped in a race car and can't reach the dash, it's mega annoying. I've invested over a $1000 in trying to get Android based dashes to happen. It just sucks for what I'm doing. Having to wait 2 minutes for the dash to come up when you just want to see the coolant temp quick is unacceptable. Just my 2 cents

[@Dirtyz1234]

I'm coming back to this video now since MaxxECU released support for the OEM TCU on the 8hp70. This made their plug in solution for my E46 an insane value since I'm getting parts together for an 8hp70 swap

[@Calvin-Nelson]

Still my favorite choice for an ECU.

[@Flitzer514]

Very cool. I was running into a wall with my Terminator when I tried to have the fans run at 90% PWM with the A/C on. It's seems like such a simple thing to work out, but it's a super pain in the ass. And, I didn't manage to figure it out.

[@Calvin-Nelson]

Yeah. Terminators are awesome for the basic stuff. The IO management just isn't there though.

[@Levibetz]

Okay yep I'm basically sold. That looks awesome. Considering a fancier ECU for the next project and the gap in quality from a 3-500$ speedy or megasquirt to a 1k$ haltech or maxxecu is seeming pretty worth it.

[@th600mike3]

I've been pretty interested in the Speeduino for a while and have been on their slack... I did some messing around with some of their stuff too. I really like it and if you're interested in a "microcontroller" deal, it's the way to go. The ARM platform, especially with a teensy 4.1, so ridiculously powerful, AND the firmware is all open source, yet still works with tuner studio. I will be running my engine on the terminator X for now, but in the future I'll definitely go another route. But for my transmission controller, I'm going full "from scratch" and basing the system off Rust rather than C, but thats a different conversation... I'm interested to hear what you liked about the Maxxecu. I just felt the Speeduino was more capable and more open ended, and others like Rusefi are also just better choices for what I'd want out of it. These are basically like poor man's Motec in the end. Now just about getting a matlab extension to do the heavy C lifting...

[@Calvin-Nelson]

Yeah. I had bad experiences with the Speeduino. I tried there most recent rev of the board at the time. Had issues with the ribbon cable interface. Then tried Twisted Builds more robust offering. That worked better, but the GM7X decoder was not working. At this stage, I don't have time to fool around with my own C coding. I just want something that works and has the ability to be adjusted to what I need. Maxxecu does everything I need. As far as your other comment goes. The tinker does exactly what I need so far. I'm very happy with it.

[@hondatech5000]

Thanks Calvin

[@Calvin-Nelson]

No problem

[@jonathanmaret1244]

Thanks for the information on Maxx and Tinker. My builder is just finishing up this combination on a 944 turbo. We are having issues with the Tinker Dash not receiving the correct canbus signal from the Maxx. How we put a user table input to the dash and what to do to change certain things such as the dash reading the injector calibration flow instead of the analog voltage input for the fuel pressure, ie reading actually fuel pressure. So far Tinker and Maxx don't want to communicate, Maxx is doing everything it is support to, we just can't find the correct channel to let the Tinker understand its data. thanks in advance Jonathan.

[@th600mike3]

A few notes on digital dashes as I have been attempting to find a marketable solution: The best solutions require very expensive licensing of higher end software. I can get the software OEMS like Mercedes Benz run for their in car stuff. It's actually not that bad as a start up for the initial license. BUT you need a lot of expensive support after that. You need to have your own linux distro running procto, that way the thing will boot up FAST. Then you need your C library to be setup correctly and not have bugs (holy shit is this a nightmare btw), and then on top of that you need it all to work with a board and display that is actually affordable. After all this is done, you end up with a dash solution that is in the 4 digit range. I mean, even if I want to make one for myself we are talking hundreds of hours of coding + whatever the amount of time to learn all that, and then quite a lot for the display and hardware. There are some out there that are around 500$ that are pretty good and run off the raspberry pi hardware and have decent linux distro behind them, however with the chip shortage, that price is going to spike. The code that runs the human to machine interface / display, just isn't available cheaply. If a company (a small company realistically is the only thing that's going to "enter" this part of the market-space), wants to develop a good display product for car displays, there will be a ton of cost in either an off the shelf solution (outsourcing to a bigger company and licensing what they create), or a lot of hours in making the interface. There are more and more solutions that can be run on bare metal that can display vector graphics, however the task of having a dash display requires more advanced high speed protocols than the "easy" stuff can provide. Its not so much that the display is really that high speed, but more that the low level bare metal solutions that can be cheaply and easily implemented, are just not designed for a high dynamic throughput. There are some solutions that appear to be approaching feasibility for making a decent and cheap dash display (software side), but even they have rapidly moved towards a licensing model that is very aggressive and prohibitive for market exploration by a small company.

Thanks for the video. I think you should also try ECUMASTER products, such as EMU Classic and EMU black, and ADU displays. I install, wire and run these on many projects, personal and customers, in my opinion very good, advanced, flexible and affordable ECUs. I may be biased however, as it is a 100% polish product :)

[@Calvin-Nelson]

Yeah. I need to dig into the software sometime and check it out.

[@madmodsgarage1179]

@@Calvin-Nelson many built in features seem similar to maxxecu, as I listened to the video. Flex fuel, vtec/vct/vvt, boost control of course, nitrous, als, launch control, flat shift, dbw, traction control, wideband and egt controlers, parametric outputs, logging every single parameter, many many more, all built in, I highly recommend it :) I'm sure they have their own disadvantages or different approach or lack some other features which are onboard in other ECUs, however, surely worth researching :)

ECUmaster has alot less I/O

[@madmodsgarage1179]

@@thewraith6360 could be, I didn't check and compare it. Black has 9 analog inputs (plus you can use at least one for 3 switches) and 6 aux outputs, plus unused injector outputs can be used as aux output. I don't know how it is in maxxecu. But in simpler, EMU Classic I actually do sometimes run out of inputs (4). But you get what you paid for, of course its alot cheaper, still having something like 80% of advanced functionality of black

Thank you!

[@hasole9669]

Would love to see your fan and transbrake config. Multi use button is very handy

[@Calvin-Nelson]

It's very easy to config in the software. You just tell it to latch for an internal output and it works.

[@kamilzmich5961]

It really is fully adaptable and configurable. Before I locked my choice on a maxxecu, I tried out the software for a few others - Link and Haltech namely. Quickly found the Maxxecu is the most 'unlocked', and although feature-on-feature they're all the same, you need special plugins and extras to do what maxx can do with just a couple of spare tables and logic variables. Again, not biased. I've used standalones, piggybacks and flash tuners. All depends on the application, somebody who just wants to add a little fuel and retard some timing won't care about the extras.

[@Calvin-Nelson]

Yup. That's why I like their products so much.

maxx feels like the budget motec, the freedom of the software is perfect for less popular engine options

I have had the same thought.

[@shawnrobertsonhorn]

I personally use an Android tablet with mine an it works flawless I used an app that wakes up the tablet an automatically opens the mdash app once it senses the charger ..an I wired the charger in the car ..plus the mdash app has the bluttooth switching so no need for physical switches an more free inputs

[@Calvin-Nelson]

For a daily driver, I'm sure that works ok. I normally go months without driving mine over the winter, and managing the charge level would be a nightmare. You could also softlock the tablet if you're not careful.

[@MartinBorn]

This all sounds so much like an industrial PLC. Especially the NC signals for safety are so basic in industrial applications. Surprisingly, no other company is really going that route.

[@Calvin-Nelson]

Yep. Spot on.

[@MartinBorn]

@@Calvin-Nelson I even know very few folks in Germany that are using an old industrial PLC to automate things in their car. Not ECU directly, only accessories but exactly because of the flexibility.

[@Calvin-Nelson]

Does it? Can Maxxecu emulate Holley CAN protocol?

[@hartiaacres]

Is this the system you will be using for the 7sec attempts with the Nova project?

[@Calvin-Nelson]

I'd love to, but only have so much money to invest. May do it eventually.

[@tsdyno]

i agree with everything else but the mdash / android complaint. I personally think it works very well for what you actually need it for. No need to wire anything and you can add bluetooth switches for what ever you like on the tablet. The bootup time will depend on you tablet/phone. But the biggest thing is that you dont have to buy a 500-1500 dollar dash to have one in the first place, you can if you want to, i belive maxxecu supports most dashes from other manufacturers like ecumaster etc... But you dont have to, if you cant afford one you can just use an old phone of yours or buy a 100 dollar tablet. you will also be able to see and reset ecu error codes, change boost levels, even change maps i belive with the bt switches. dont know if you can do all that with the dashes and thats for a fraction of the price. ofcourse if you're building a full race car you will probably want a dash instead of a tablet, but for street cars the tablet works perfectly... and it wont run out of battery, just plug a 12v socket charger in or keep it plugged in.....

[@Calvin-Nelson]

I've tried the tablet dash so many times. They have always sucked in my experience. It sucks have to poke at a dash when you're strapped into a car with gloves on and can't reach it. I wish they had a robust stand alone offering. I'd pay good money for it too. To each their own.

[@tsdyno]

@@Calvin-Nelson Yeah i can undestand it in a race car ofc, but street car no problem imo. And yeah if maxxecu themself made an affordable option would be great. but tbh you dont have to poke at it, just turn it on before going out on the track or on a street drive.

Perfect timing for the video, I am looking for a ECU to control my Gen 6 502 big block Chevy with the Chevrolet performance cam and crank signal conversion timing cover. I was thinking of the Holley terminator max because it will control the 4L80e and do sequential injection and spark control for the LS coils I’m going to run with the L21 valve covers(think 8.1 gen7 valve covers and coil setup) my problem is that if I make any changes like a 6L90e it won’t support it. With this Max ECU where do you get the engine wiring harness? Does it support GM sensors and injectors? What trans control? Auto learn function for the tuning? This motor is going in a motorhome to tow an enclosed trailer so I’d also like to use a mass air sensor to adjust for elevation changes and weather conditions instead of relying on the O2 sensor to take care of it all. Any thoughts would be greatly appreciated.

[@BEANS-O-MATICtransmissions]

For durability, ease and expense, id stick with a 4l80e for your application. Also, an X-max would also fit this simple application as well. For a drag combo or something that gets changed often, I'd maybe look into this ecu. But for you, the Holley would be money and time easier. JMO

[@Calvin-Nelson]

Yeah. Holley is hard to beat for this particular case. It works great for the more basic setups like yours. I think Maxxecu makes harnesses. I normally make my own. They support GM sensors. They have autolearn, and trans control. It could definitely be made to work.

It's weird that you would say "it's the closest thing to a microcontroller I've ever used" when a speeduino is a programmable microcontroller. There are a lot of drawbacks to speeduino but don't deny the ATMega in its heart.

[@Calvin-Nelson]

I don't want a microcontroller though. I want the flexibility of a microcontroller with none of the R&D on trying to make stupid crap that shouldn't have issues work. The Maxxecu so far, has given everything I want in a package where the dumb stuff just works. Speeduino hasn't (I've tried).

[@Johnfrank249sc-w4ddx]

Are you going to load a maxxECU base tune on your wiki for the 4200, be cooler if you did lol

[@Calvin-Nelson]

Yeah. I keep forgetting. For a while I didn't want to upload it because it was still actively being developed. I think we're in a good spot now. I'll try to remember tomorrow

If you feel the need to go “pro mod full fancy pants”, just get the Holley Dominator and be done with it. Otherwise your gold box with a tinker dash and and an output extender will take you plenty far with what you are doing.

[@Calvin-Nelson]

This is not a gold box. This is a Maxxecu. Maxxecu has a dominator equivalent called the Maxxecu Pro. I would take it over a dominator every day of the week.

Good review, awesome product but one thing to consider, their customer service. Been a part of the Maxxecu community for years and have watched genuinely interested people get reamed or belittled by Nathaniel for simply asking a question on their support pages. Initially I thought it was a language barrier thing since he’d snap at really subtle phrasing or wording but after lurking for a few years l I’ve noticed it isn’t because there is no consistency with his attitude. It was enough that I started looking at other options for DCT control. Sad because the product itself, their wiring harness quality, is all great. But I refused to give 3k to an overseas company with an attitude regardless of how good the product is. Personally can’t wait for Haltech to break into the trans game. Once that comes thru these niche entitled companies might have something to worry about. Just my long winding experience with maxxecu. Outside of DCT and now 8HP control and certain perks of their IO, they’re like any other standalone just with an attitude 😂

[@Calvin-Nelson]

Yeah. Problem is everything else I've used doesn't even come close. Personally I have had to contact Maxxecu support one time to get the 4200 added to their supported trigger types. They went above and beyond.

[@dxd48c]

What about Haltech?

[@Calvin-Nelson]

Their software is pretty limiting from what I have gathered from looking at their turning software. I hear the Nexus is very powerful, but they're also very expensive.

[@flarez_hd1753]

Haltech make you buy a ton of modules to match the functionality of a Maxx system.

[@199rocks94]

How good is the closed loop fueling with this?

[@Calvin-Nelson]

It's pretty good, but I haven't tested it like I have a Holley.

[@199rocks94]

I currently have a Holley but I too would like more input and output control but I just like the closed loop so much

[@Calvin-Nelson]

@@199rocks94 I've grown to not trust in the closed loop. It's a two edged sword. If that o2 sensor is reading right, it's great. The second it doesn't, bad stuff can happen.

[@jameswest2688]

would you take this over fueltech? have you used fueltech yet?

[@Calvin-Nelson]

I haven't used fueltech yet, but just from poking around in the software, it seems a lot like a megasquirt with a bit more functionality. The answer is most likely yes. The fuel tech has a lot of features, but they really don't allow you to go nuts and implement custom stuff, or think outside of the box. If you can't get what you want with their box, then too bad.

See FB Group MLVHD. Many if not most of the engine log examples are generated with a MaxxECU. You would not believe all of the cool stuff I am doing with my Maxx Race and custom tables and math channels. Good video.

I'll check that out. I have one math table as you saw on the video for converter slip. Definitely need more.
