GR Supra 101: Routes to big power

[_Sp1ral0ut]

@D3ad_Hand MHD+ is now available for the Post-June 2020 ECUs with the updated FEMTO unlock. Which, as I understood, means Motive reflex is now fully integrated for PI control with MHD.

Unless I'm mistaken, then by all means anyone that knows more can elaborate.

This is correct.

Not sure if this is the right spot for this, so apologies, but is there any vendors out there that accept crypto as a form of payment?

I really want to get a pure900, but not sure if any vendor out here can make it happen lol

I got 0 knowledge about that, but good luck.

I’m not gonna lie, I’m still not sure if I want to upgrade DI or just go PI. I do like how simple the DI route seems. Have a bm3 flex fuel kit already setup. If I go PI, will I have to undo the wiring for the flex fuel kit to setup the motiv reflex?

DI has come a long away from where we first started. However, PI still provides more power. I might go DI myself. As for your question I dont think so. But I am not sure I will let someone with more knowledge answer this question.

Stage 2+/HPFP Question:

MHD lists Stage 2+ OTS map as requiring the HPFP to be upgraded.. I seemed to recall this isn't really necessary?

I'm on a stock airbox, upgraded charge and intake pipe with a 200 cel cat DP. Also running 98RON (93) exclusively.

With reliability being my main concern, can I safely run the Stage 2+ OTS map without a HPFP upgrade or should I just stick to the Stage 2 OTS map?

Thoughts?

Also may as well ask: How often should I aim to replace my spark plugs on this setup?

That's for Gen 1 B58. No need for Gen 2 B58

Thanks mate. Complete newb to tunes here. And reading, it would seem. ?

Wait.. I read that as Stage 2+ being for gen 1 only?

Stage 2+ HPFP is for gen 1 only. Gen 1 has an OEM HPFP that flows less than Gen 2.

Makes sense. Cheers.

I thought the stock turbo was fine on pump gas until I tried a bigger turbo (CTS). Even at the same boost level, on pump gas, on factory fuel system the big turbo setup was way faster than stock turbo (560 rwhp on 92 and meth). The big turbo also gave that increasing with RPM power curve I love so much.

This sounds about right for stock fuel system on pump gas. Add PI and you'll be 600+ no problem. Any other mods with to go along with the bigger turbo (primarily intake manifold)? Or just bigger turbo and tune? And what tuning platform?

Saw a bimmerpost thread on bm3 rev2 board. Looks like it may release soon, install videos are being produced according to them. Decided to go PI, but piecing things out while waiting for the rev2 board

well BM3 did say the were releasing it soon, but that didn't happen so unless we have a date I'm not holding my breath. They tend to do this lol.

I spoke with the (REV)Board of Directors of BM3 this morning. They assured me it will be released in two weeks, which is the start of their new quarter.

I informed them if this doesn't happen we will rise up and protest. We will storm their office and take over. We will have with us the B58 Shaman and a fellow named Luigi Mangione, who was with a group of friends, including myself, at the track on December 4, 2024 from 6am to 8pm.

Let's see what happens in two weeks.
