Thundermax ECM Set Up and Base Mapping : Pro Tip

[@NormalSoMDStuff]

Can you do a video of how to dial in the AFR and TIMING tables ?

[@markgraves9429]

This tuner will only cover so much +/- with auto tune. Ride a tank out and plug it up and see how far off the fuel point are off. Rewrite the map. Now any point that were outside of auto tune may be within the tuning range. I have had mine since May 23 and have rewrote the map several times now and the bike runs it's ass off. No hard starts, popping or pinging. Awesome product

Great informative video. I’ve been dragging my feet on getting a thundermax for my 2012 road glide. I’m doing it this season!

[@kadsafm8288]

Did you add it? How do you like it so far?

[@winstonaw91]

Hope you can have a video to show the basics of adjusting the AFR and VE of the fuel table

[@JayWingfield03]

Exactly. They don’t tell you the importance of having that dialed in also. It’s definitely not a plug and play system. It’s more to it

[@danielgraham9104]

​@jtweezie100 it adjust itself the more you ride the better it gets, definitely not going to run like you just got off a dyno machine but put 300 miles on and add your learned values to your map easy as ABC...

hi informative video i can see a few problems for me i'm not running a HD speedo,any work a rounds thank you

[@jimbolen3599]

Great video

[@ranenglazier4257]

I see they make a Thundermax for 2020 touring but what about a 2021 street glide?

[@danielstout9939]

I just installedThunder -Max on 2020 streetglide best purchase ever this tuner is the best one out there in my opinion definitely recommend this

[@visualoutlaw]

Can you use this tuner with the stock exhaust? If so, will any additional parts or mods be needed?

[@jacobrusso9522]

Great video thank you. I bought an 05 Electra glide and it has this tuner on it. It runs great for the most part but right off of idle sometimes it will pop/cough real quick then go. If i dont have any information about the tuner, can i plug into a laptop and make cheanges or see info from the bike?

Very cool. Gonna have to get one

I’m installing a thundermax on my 2022 FXLRS tomorrow and i have a TBR shorty turnout, I’m not sure if i can clear with the wide band sensor on the front head pipe, looks like it will contact the engine, any insight??

[@user-sb8rp5my7g]

Awesome video guys really enjoyed it but you made one mistake you should never put dielectric grease right on your connections dielectric grease is an insulator and doesn't conduct electricity I see people make this mistake all the time.

[@prosedi17]

thats right did that on my o2 sensors,instant no info engine light on said not conducting info to ecm

[@scotthenry7488]

So where do u put it then ??

[@thecallingdeath]

@@scotthenry7488you would put in something like your battery connectors on your car or truck

[@charlesd6459]

Actually, the dielectric grease does go on the connector if it’s a friction type pin connection which it is so what you do is you put a little bit on each connector connect and reconnect 10 times that pushes the grease to the back and allows the friction, male and female to make contact

[@allanmccullough8550]

[@ericv79flh]

I hear so often that the bike needs to be dyno tuned after a tuner is installed. Thank you for dispelling that myth.

[@ricklabreche7893]

They get working with bikes equipped with rdrs yet

[@gplaycount3154]

Is internet required?

[@bigworm6635]

When resetting by doing 3 times on and off, do you start it on third on or on the 4th ? I don’t have mine hooked to a laptop yet , what cable do I need and software is on their site ? Thanks 🙏

[@vinm3630]

Turn key on and leave on for 30 seconds. Then turn off and leave for 30 seconds. Repeat 3 times. After the third time of turning the key off, you are all clear to start.

[@tommyjoyce477]

I have a 2019 rgs and I put a Thurber max in and I had trouble starting my bike in the cold. You have any fix for that

[@mydogschauffer]

There is a built in fix for your issue. I can't find the exact procedure at this time. It involves hooking up your computer, running a Cold Start program and it's supposed to cure the problem.

[@jpphd5685]

Very good video and tuner. Will the bike run bad at first and gradually get better like the V&H FP3 Autotuner?

[@ryantidwell19]

The thunder max is nothing like the FP3 but yes it will get better and after I say a few tanks of gas you write your learned adjustments under “map editing tab” on your laptop and it makes a huge difference. A lot of ppl miss this with the thunder max and give it bad reviews saying power vision is better but after a few times it’s damn near close if not on par with a dyno tune and you have no limitations with your upgrades! My TBR 2-1 had the torque dip everyone talks about and after the thunder max learned low end improved dramatically.

[@martinXY]

@@ryantidwell19 Is the torque dip gone now, or just better than it was.

[@ryantidwell19]

@@martinXY no but it’s not gone due to it being a short pipe but the pipe is a lot throatier than the longer 2-1 and lighter than most 11 lbs vs most at 30 lbs but it’s definitely not an issue. At first it was a problem before the tuner did it’s thing because it would run about like a stock bike then gradually build to a hard pull after 3000 rpm but now it’s a strong pull from low end and gradually pulls through the RPM.

[@jessel2971]

The Vance & Hines will never get better. You’ll just get used to it running like garbage.

[@kanenaysmith9287]

@@ryantidwell19 Do you prefer the Thundermax over a dyno tune? Are you still running the Thundermax? what mods are done to the motor? Im stongly thinking of dumppoing the FP3 and getting a thundermax. I will be doing a fair bit of engine work and dont want to get a dyno each time. Any help is appreciated, Thank you

[@plavnyphotography9871]

TO bad the one my buddy bought does not work!! the port to connect the usb to the com on the module is bad so its more or less a brick

[@Krippztr]

Does it autowrite the map to the ECM? Or do you need to manually write over the "basemap?" with the new improved map you get when riding? To get a "new" more accurate baseline?

[@johndarling2771]

It auto tunes while riding, no more changing the base map unless you do other changes.

[@tailgunnerdenis3331]

Sorry but you are wrong. The base map will always only be the base map you installed!!! You absolutely MUST write the learned fuel off-sets from your riding to the loaded base map to built YOUR bike specific custom map. This ensures your bikes base map will always retain all your riding/map building history. P.s. you should also ALWAYS save the map afterward in the software file/folder system based on Date modified. This allows you to load the previously saved map should you ever experience a map corruption from a gremlin eg. loss of electrical power to ecm etc. Just some free words of advice. 😊 Enjoy…..Thundermax in all my builds…air/exhaust to full big bore/cams/heads……have fun.

[@okeygriffithjr8565]

I just got a wave tune but don't have a laptop. Does the thundermax have to be attached to the bike to load the base map?

[@johnholley7749]

Yes it does

[@chrisburch9513]

I get it dielectric geese on the connector pin keeps mechanics employed. But it works better if it doesn't coat the electrical contact surfaces.

[@connork509]

Don’t all m8s have ACRs? I’m confused about that part.

[@UnrulyRider]

@@ihateemael 🤣

[@vinm3630]

I can't find any videos explaining what to do AFTER you have put some miles on and it has been auto tuning. How do you save the new tune? Do you leave auto tune on all the time? There's plenty of videos explaining the set up but nothing after that. Say I've put on 100 miles after set up....now what?

[@markgraves9429]

The unit lives on the bike. You hook your laptop up to the tuner and a chart will show you the points it has adjusted from the original map. At that point you just enter the updated map and the tuner will then auto tune the new map. Once you've done this a couple of times the tune is perfect and then it will adjust to weather, and altitude.

[@vinm3630]

@mark graves That's all that's ever explained in any videos online. There's no explanation of any other settings on the laptop after setup. There are many menus and tabs and other settings but no instructions other than basic setup.

[@markgraves9429]

@@vinm3630 I saw one today that is a 2 part that did a fair job of explaining this subject. I to don't know. I live close to a HD dealer and have a bud of mine that works there. I'll run by there every now and again and he takes care of it for me.

I just paid my Indy $550.00 Canadian to dyno-tune my Softail after they built up a 124” for me… what does this setup cost roughly? What’s better… an actual dyno-tuned tune or this setup? Are you able to pull hp and tq charts from the laptop as well after taking the bike out for a good rip?

[@chazzcapone.]

You can’t pull HP or TQ from this. That is done on a dyno. A dyno tune is always better. But it isn’t always required. The cost of purchasing the tuner & software is around $1,100 US dollars.

[@780tunertube7]

Can I do this myself or do I need to bring it to a dealership to get it married to the bike?

You can do this yourself. It replaces the stock ECM so no “marrying” required.

The instructions with that tuner are hardly a comprehensive affair.

[@ryantidwell19]

I have the same cam. Plug in your Tmax to the computer and write your learned adjustments from “map editing” and select “auto tune learned adjustments “ this will hard write learned adjustments and you will notice a huge difference and once or twice a week keep doing that till it’s perfect.

i dont see any need of installing a over 1.000 $ product that needs to be calibrated the next 2k miles. it would be a lot easier and less expensive to do a dyno run that calibrates the bike perfect for the street.

[@beri232]

Just had my shop build my 124” in my 2014 Fatboy Lo. A custom dyno tune was $550 Canadian. I think this kit sells for well over $1,200 Canadian. Not sure why anyone would buy this? It can’t give you a dyno chart so how can you see your tq and hp curves?

[@markgraves9429]

I have a 03 Screamin Eagle Deuce that most tuners wont work with. Harley said they could flash a map that might be close but not perfect. So I went with this for the stage lll. Works like a charm and was easy to update the map after a couple of tanks of fuel. The unit then would calibrate the new map. A couple of times doing this the bike is perfect and will adjust to any mods I make from now on.
