A series on rewiring a complete street car with indicators, headlights, heater etc from scratch using a PDM or vcm would be fantastic!!

[@ziggyortiz37]

I second this! Lol and haltech would be the only brand I'd trust with that task! Come on mates!! We want a see another wiring vid by the man (Dave) himself! 🥰🥰 lol good on you guys!! You guys I swear are the best of thr best!

Anyone notice Scotty sounds like a spooling turbo when he says two…great video btw

[@SawyerMotorsports]

Welp this video just swayed me to haltech over Holley. Thanks!

Can't wait for the day of Direct Injection support.

[@zen4sen]

Thank you, exactly the info I needed on connecting additional PD16’s. You guys rock. Now I just gotta wait for Black Friday 😂

Here to just make sure yall stay passed 250k subscribers. Id love to run this on my Cressida someday cheers. To making some rad products

[@brianross4057]

I'm glad this came out in time as I was about to go Holley for the LS1 4l60e in an LN106 Hilux which has been running trouble free with the factory Delco ECU, problem is I live 200k from a tuner and was looking at a mafless wide band setup which is native to the Nexus, I was watching Joe Simpson and he explained that the Holley comes with a wizard to get you going but it will not self tune and will need a tuner to clean it up, I like the look of the Nexus 3 as I have found it comes with the standard LS1 4l60 tune from a VY Commodore which is what I have got and that I can de-pin the Delco ECU and the pins will go straight into the Nexus connector and use the GM Factory engine transmission loom, The other thing is I can have a trigger from the 4x4 switch into the Nexus to switch to another tune map to change shift to manul mode with paddles setup on the wheel and control the lockup for direct drive, The other thing is the Nexus 3 is cheaper than the Holley and I'm sure that the support from Haltech being local will be much easier as well.

[@TURBOTRISTO]

Great video boys love haltech products

[@karlfrost2909]

Awesome thanks Scott

[@4fourjaw]

Hi Scotty, in reference to traction control, if I have a 4x4 can your units control brake slip/ABS on each wheel, I mean via the ABS module and of course torque management?

[@miticogallo1152]

Hello, is there a possibility (even in the future) that it is possible to insert custom can bus channel into the NSP?

[@andrew1977au]

Definitely do a quote tune video Scotty

[@Dansyoung]

I’m looking for advice on where to find more information on these computers in specific applications. I have an 05 Mazda rx8 I am going to put a LS engine into. My understanding is that there is an emulator for the rx8 with Haltech that will allow me to take out my rx8 pcm, have the Haltech installed in its place on the can bus. Hoping to retain all factory functions (such as ABS and dynamic steering, cluster operations speedo, tacho), but use the inputs from these factory components to be able to setup traction control through the Haltech. Also looking for more information on the customization of output controls with the Haltech - can I program an output for something like a reverse lockout solenoid (have it only apply when vehicle speed is under a certain value, and brake/clutch pedal depressed?)

[@5t341tH]

Please do a video on quicktune specifically!

[@xuk]

Can I still using the factory wiring & fuses with R3 just use as ECU and logger, maybe only power the fan and pump for now? Apparently too lazy to remove current body harness.

[@rotaryperfection]

My plan is to do a Renesis swap into a 2016 or 2017 ND Miata. My engine will have a custom intake setup for semi PP so I will have to run an aftermarket ecu. I want as much of the factory gauge cluster to work with A/C, power steering, and cruise if possible. I've already done my own 20b swap into my 94 FD back in 2009 with an older E11V2 and have those above convinces but the modern electrical with obd2 and canbus are giving me a headach in trying to figure out. Will any of these ecus work to get everyting in an ND miata or will I have to use some sort of canbus interface?

[@kumaragurusaravanan2248]

does the nexus R3 and R5 do stability control and torque vectoring? like the NEXUS ECUs work with honda torque vectoring(SH-AWD, VTM4, and i-VTM4), Mitsubishi S-AWC, BMW Dynamic Performance Control, Audi Quattro, and Subaru Symmetrical All Wheel Drive

[@daviddetweiler7658]

Hi Scotty and team! I'm currently building out a NA 20B FC. I plan on using the Nexus R3 and curious how I would manage my high amp outputs. 1 for IGN1-a coils 1 for fuel injectors 1 for fuel pump 1 for a PWM controlled fan? Or would i be better tp save that for an OEM fan equipped with a built in solid state relay?

[@Low760]

Contact them directly, they have a good customer service team. But if you watch the video you will be able to work it out.

[@PyroBlock]

I hope you guys support direct injection soon, I really want to use the nexus r5, but it has no way of working for my motor

[@Zuki14x]

Does the R3 have any type of EGT tuning or control?

[@LujinCustom]

Something I’ve been tossing around, is multiple exhaust thermocouples in the manifold. The purpose, is to control individual cylinder AFR with combustion heat signatures instead of multiple wideband o2s in the flame front. That way you can optimize each cylinder.

[@HomeSkillet832]

That exists on eam website

[@LujinCustom]

@@HomeSkillet832 which Haltech ecu is that?

[@NathanaelNaused]

why do that instead of having one wideband per cylinder?

[@LujinCustom]

@@NathanaelNaused it was my understanding that you don’t want them in or too close to the flame front. Also, I don’t think the wideband can tell you exhaust temps. Knowing which cylinder or bank of cylinders is running hotter than the rest is valuable info One more thing. Thermocouples can be a lot smaller and take up less space than a header or turbo manifold full of o2 sensors.

[@jgizzy]

@@LujinCustom I suspect they don't do this because the thermocouples don't react/read as quickly as a wideband sensor, being entirely too slow to be of any real use during high stress operations as an on-the-fly tuning monitor.

[@gordowg1wg145]

That was a very informative presentation - I often see people asking about how many channels different brands' ECUs can handle and with that much flexibility for adding multiple PDMs and key-pads* there should be enough for just about anybody. Next video could be setting up the display options - Haltech and off-brand, and how many can be used at a time? Some may prefer a main panel in front of the driver with the basics like speedo', tach', oil pressure, fuel, water temp', etc in an "analogue" looking display as the default, with a secondary, central panel displaying more detailed info' on the various functions being controlled by the ECU/PDM like HVAC settings, pumps, fans, other temp's, etc. Perhaps a third in front of a ca-driver? *compatability for different pad and/or wheel mounted controls, especially proportional or multiple position switchgear - such as for brake and/or engine management settings for different condtions?

[@RWB1111]

Support for ford e-series auto BTR?

[@dan91sgarage]

Just wanted to check if the Elite 550 had been discontinued? It seemed like the ideal entry level 4 pot standalone upgrade (fitted my budget too) and I can't see it for sale at many retailers?

[@Low760]

Yeah, gone. The 750 is better for a four cylinder I think just for more inputs and outputs available, more data is better.

[@dan91sgarage]

@@Low760 The problem is, I don't need any more inputs / outputs for my intended build and the 550 was the right price for me. Shame really, but if there's not enough demand then I guess that's why it was discontinued.

[@MyFearEatsMe]

Does the Nexus R3 still support a 2JZ driving off primary 1050 injectors for everyday driving with 2600 secondary injectors only there for lets say when you decide to get rowdy or above a certain boost limit?

[@bearsstuff]

I wasn’t aware of the GM transmission control. Can you or do you have plans for Ford’s 6R80?

[@Low760]

If it does zf 6 speed for Falcons, which are related boxes, I'd say so.

[@bearsstuff]

@@Low760 If it can, I'll order one today. I'm only aware of one company that can control the 6R80 and it's unclear how their box works alongside an aftermarket ECU. But to have a Coyote and a 6R80 in my 40 Ford would be *incredible*!

[@bearsstuff]

@@Low760 So looking at this further, the ZF seems to have a TCM, but the 6R80 uses the PCM to control the trans. Motec and Quick 6 seem to have controllers for the 6R80.

[@BourneThisWay]

Platinum series! 🤌

[@glennben2804]

As mentioned you can power your whole car with the Nexus. Can you still use factory switches to trigger things like indicators, lights etc to keep an OEM looking interior? or are you required to install a keypad to trigger these items.

[@Low760]

Yes you can, nugget garage has done it more than once.

[@richardallen1629]

factory switches can be wired as inputs to the ecu, and the lights/wipers etc wired as outputs from the ecu, then you tell the ecu what switches trigger what outputs 👍 you could even use the pwm outputs to fade your lights just for fun...

[@glennben2804]

@@Low760 thanks I will have a search.

it just hit me today ,Haltech is missing the boat not having a conversion for John Deere tractors. There are a ton of pissed off farmers out there JD is holding hostage and I garrote you they would change over to something like this given the opportunity

[@ReubenHorner]

Surely the elite series will be retired soon. Not that it's a bad product but competitors have had several iterations in the same time

[@haltech]

Not everyone needs, or wants, the latest and the greatest. There's still plenty of demand for simple, entry level ECUs, and for as long as there's demand we'll keep making them.

[@ralmslb]

The Nexus is not a replacement for the Elite, price alone, is over twice the price and not everyone wants to fully replace their power delivery system.

[@TURBOTRISTO]

Nothing wrong with an elite 1500 or 2500, I’m more of the opinion as to why it even got replaced in the first place it’s fantastic

[@ReubenHorner]

Absolutely understand but I was more thinking a direct replacement for the elite series

[@omegamanRA28]

I would hope the elite 550 at least will still get the love the 750 gets ie updates. Its not worth upgrading my 550 for 750 or above on a 4 cyl, not yet anyway. it has a can bus, thermo tc4 and waiting on a budget friendly IO box...to round it out. oh and WB.
