GR Supra 101: Routes to big power

[S2k]

First off, I believe Visconti about as far as I can throw him.

Secondly, if you have done the brake recall , bm3 doesn’t replace that.

Cool, good to know! (I will take Visconti info with a pinch of salt!)

I assume you are using BM3? (Which is really good to know as you are definitely one of the Supra “super users” on here where I am thinking BM3 for my car!)

You will probably now tell me BM3 is a pile of crap! ??

I do use BM3. It's a great platform. About a year ago everyone would parrot "ECUTEK IS GOD! ECUTEK IS GOD! ALL OTHER TUNING SOLUTIONS ARE CRAP!" without knowing what they where talking about.

It's since quieted down, probably because June 2020+ ECU's can now have BM3 CustomROM with no cloning required, unlike Ecutek. Once BM3 releases their PI controller, Ecutek will die off even more. I've literally seen this same thing happen over and over again to Ecutek on different platforms over the last twenty years.

Fixed that for you.

But for now, ECUTek is king, and nothing else comes close...

At least for us car bowling folks.

Not correct. The original rom on the car is over written with BM3. The stock rom in BM3 is whatever they have on their server for the car. Just to be clear: BM3 does NOT read out your stock rom and store it.

Just went through this with them. My original ROM on the car didn’t need bench unlock. Now if going back to “stock”, I need a bench unlock as the ROM on their server is newer than what was originally on the car.

I stand corrected.

Is Motec working on getting something out for our cars?

Hey all! Question. Currently running jb4, but looking to do a Femto unlock next year.
Eventually I want to do an upgraded turbo, it seems to get the most out of it, PI is recommended. Assuming I go bm3, do I install PI first and then upgrade the turbo? Or upgrade the turbo first then PI? Can I run an upgraded turbo with a ots map while I wait for PI and then do a custom tune?

im just curious what the actual process looks like. I’d like to have the least amount of downtime in my car as possible.

You need to have a good game plan first. If you require the ability to run over 30% ethanol E85 on an aftermarket turbo, you need PI, flex fuel sensor, and Reflex all at the same time. Why? Well the reflex changes where you bring in the flex fuel sensor. Meaning the flex fuel sensor wires to the reflex not a can bus integration box. Also your tune is different DI Vs DI/PI.

You can install a stock location upgraded turbo and run it on the OTS map. I do not recommend getting into lots of boost as the WGDC tuning is way off. Direct injection, 92 octane pump, cts turbo gas and meth injection got me 560whp without PI.

so in theory, i need to install PI, flex fuel and reflex all at the same time like you said. Would I want to install this stuff before or after the turbo?

You can install the Reflex, PI, E sensor whenever. The key piece of info is you need a tune to run PI or an upgraded turbo. The reflex wiring, PI and E sensor can be installed but not utilized until you are ready for a turbo upgrade and tune. Once you are tuned for PI Reflex, you have to utilize those tunes and keep PI functional. Meaning you can't just unplug the Reflex, unless you have a non PI reflex tune too, but most don't.

I didn't get that memo. I track my Supra in E45 on an aftermarket turbo. It's all in the tuning. This whole "everyone needs PI" BS is so boring.

A good amount of people using E50+ with DI upgrade on aftermarket turbos as well. The whole PI thing is needed to make power is so last year.

@razorlab knowing you would read that I should have worded my response a little different. PI is likely needed if you want to run way over 30% E at high boost pressure, lets assume 80% E at 36 PSI. We know that DI is better than PI. The only reason we put PI on these cars is to solve fuel delivery at high E% and boost pressures...

what is the DI upgrade?
Is that HPFP, and LPFP?

HPFP, Injectors, etc

I'd actually be interested to see what the guys with upgraded HPFP, Injectors and LPFP are getting away with for boost. Not much difference E60 to E80 tuning wise.

I'll never run that high of boost since I track the car.
