What Is Torque Mapping? | Torque Based ECU Tuning

""Now they may not be 100% right, but as Murray Coote would say, they're 80% right and 20% not wrong.""

What was great, is now even better! But how does torque control work in MoTeC's firmware update?

There is no shortage of quality ECU options on the market these days, and @MoTeCglobal are certainly well set up with their product lineup and software layout which allows the purchase of some packages giving those with the right skillset almost limitless possibilities. On top of this though there is of course still internal development, and the recent release of torque-based control features as discussed with Brad Sheriff of Racetech Performance at the @WorldTimeAttackChallenge.

The biggest takeaway from the discussion here other than added performance capabilities is also the fact that if you don't want to leverage them, you are still fine to use your MoTeC M1 ECU as you always have.

"Dont want to lose our viewers" ... buddy that's what we're here for :)

[SaltySRT]

The amount of knowledge drop on this channel continues to amaze me. A decade ago I thought my boost-by-gear was all I needed and best thing since sliced bread, this is so many more levels beyond that. Thanks again for the content.

[power]

THIS HAS GOT TO BE THE BEST TUNING INFORMATION CHANNEL ON HANDS DOWN THANK YOU FOR YOUR TIME AND EFFORT

[adammoore]

Hats off again to Andre.
The fact that this can be explained and easily retained by the viewer in a little over 20min video is dead set down to how well you conduct the interview as a whole.
From your knowledge of the subject matter, the words you use, how clearly you speak, the questions asked.
Awesome as usual 🤙

[barongogenzoler]

Actually, torque model is for everyone and OEM has proven this and we finally have ultimate ECU for engine swaps that gives you everything that original computer did. Torque management gives you not only ability to control tire slip but also gives you basis to integrate standalone in modern chassis that relay on torque model in their ABS/ESP modules, automatic transmissions, awd controlled differentials etc. And with conjunction with fully configurable CAN bus this standalone allows you to integrate every engine almost in every car, just imagine W206 Mercedes with Coyote with fully functional MB electronics, a lot of work but what's result!

Need to watch that a few more times.
Gold mine of info.
Brilliant interview as usual.

[syrthdrsybr]

It's always a treat listening to an artist talk about his craft, straight to the point with the technical details and ground breaking insight.

Will definitely have to watch several times to unpack all the useful info this guy just casually dropped.

[johnny_gtr]

This was a brilliant interview. The knowledge of the interviewee and his matter-of-fact delivery is brilliant. Nothing to hide, just good, solid information.
Well done to Andre as well for asking the right questions.

[jkotka]

in around 1990 saab started using the method of calculating from MAF the amount of air per combustion event in mg, this value maps directly to the torque. from this you can get to a map where you are mapping torque request over rpm and tp. which works actually very well, the ecu will request boost based on the torque request, you need to calibrate the turbo map, but after that its just magic. fueling you can directly calculate from the air amount, which ever lambda you want. I've been missing this functionality in all standalon ecus since. Also the same oem ECU used the spark plugs to measure ionisation current to read knock, to allow for max power for the fuel used, and used the lambdas to estimate what the ethanol content of the fuel is to work as flexifuel system without extra sensors.

[Beansswtf]

Could listen to this guy all day haha. Would be ace for longer podcast style sittings!

[hpa]

HELP!
Enjoyed our podcasts? Help us, we'll make you 'podcast famous' and give you free stuff!
Leave a review, it can be in the form of a question and if we read it out at the end of a future episode we'll also give you a free tee, mug or clippings of Andre's back hair, your choice!

PS: Thanks for the support and for tuning in (dum, dum, psh!)- Taz 🧔🏻

[barongogenzoler]

Ironically that functionality introduced for OEM in late 90s became sensation in top range standalone in 2022. Maybe in 10 years we would have ionic currents to detect preignition like Saab in 1994.

[zerodrift]

I've watched this video so many times. Great content, discussion and visual aids. Absolutely stellar breakdown of something that quite complex. HPA team, well done. This video has inspired me as the firmware and strategies are exactly what I'm after on my build.

[driftpig]

So good I love this kind of content! the HP ABC Wainui kindy spell it out approach gets kinda tiring sometimes, love how Andre couldn't even stop him, he tried slamming the anchors a few times to no avail. Let the man go Dre the guys that are at this level can understand him

[RBGgermanKXF]

Very very interesting. Have been wondering when theres another step towards torque based. Though from my understanding it's still a ways off what's in a OEM ECU. Which of course totally understandable, we don't all have engine Dyno's etc 😂
It makes sense that for the system to work well the ignition timing needs to be completely or mostly set to MBT but this will mean you would only be able to get the max from this package with an appropriate dyno that can do MBT.
The traction control strategy sounds awesome.

Also like what they were doing with throttle even before this system for driveability. Know I definitely know to try it as I've been thinking about it for a while.

Awesome stuff. Good start to the morning

[ZEPRATGERNODT]

I'll have to listen to this again as it is very interesting to fully understand.

[moedigzz]

This type of engine management has been used for DECADES by the large car/truck manufacturers. It has been the standard for all engine management systems produced for these manufacturers. This is HOW ANTIQUATED most standalone/aftermarket engine management systems are. Most are using tuning theories and electronics that are at least a decade old.

[Lucas]

Torque Mapping is pretty well tested and used with the honda L15B turbo motor. I think the video makes it sound like racecar tech or magic, but I think its just an easier ways for engineers to keep track of wheelspeed for telemetry adjustments (read TCS).

[TheAnonymousone]

This was an amazing technical interview
