I don't see anything wrong in the log, but I will say that all the cars I custom tune running 7s or low 8s are only 21-22 psi with more like 18-19 degrees timing. Most likely you will run 8s no problem when IATs are not 110+.

That will help but also a custom map would too :)

Yes, pretty heatsoaked at 130+ iat. RF(load) limit #2 active - aka boost limiter. I can't remember which exact limit that is but most likely the one related to IATs. Try to get a log with IAT closer to ambient. I don't see anything wrong with it otherwise. typical for OTS

I did sport+, pretty much just makes pedal more linear. Also you can turn off the fake engine noise through the speakers I believe.

Not sure tbh, I did it in 2024. Just enabled stop start memory. Turn off once and forget.

Very nice, one of the few I would potentially replace Supra for

yeah car should have no problem handling a few more degrees timing, usually pump gas peaks around 10-12 degrees near redline for a p800 I'd personally run it a little richer too, closer to 12 afr

bimmercode that out and never think about it again:thumbsup:

Just use the IAT timing correction tables so it pulls a few degrees out when its over 125, thats what I do.

I keep all my pump gas maps between 12-12.2 afr, e40-e50 is at 12.6-12.8(but runs leaner below 5000 rpm to not crash hpfp) On pump gas I don't recommend pushing over 85% wgdc either, ideally around 80%. air gets too hot for the fuel. Then add timing last. Forget all the compressor/turbine...

MHD tuning guide, ecutek tuning guide, @razorlab self tuning thread, MHD DIY Tuning on Facebook and 100+ hours testing and revising on my own car(and some friends cars) The Tuning Tools web app helps too if you have a reference tune to "reverse engineer". Look at @QTR FMS thread for some tune...

It took me a few months to learn tuning on MHD but its a pretty big commitment. It has clutch torque limits you can use.

I mean your motor will be fine even if he beat on it a little. I had to make sure my car never saw a highway until it was PPF'd. So I would have been pissed.

Mine had like ~20mi on it and I wasn't too pleased with it either. No, your GM did not need to go "fill the tank up".

If you already have corrections, I would not spoof.

Hey hey... I've got most of them with HPFP MSV <105° (85%) and injectors <85% and under 13 afr ;) Haven't seen many do E50 stock fueling better than I have. Anyone post up a log to prove me wrong. https://norcalmotorsports.org/logapp/share.html?t=3c1dd62056a8ed21831d13e6 generally a 700nm...

Yeah you probably could, but The injectors are almost 1/10 the cost of the hpfp so may as well lol https://www.fcpeuro.com/products/bmw-direct-fuel-injector-bosch-13538671991 Really the hpfp need to be tuned for otherwise fuel pressure may be all over the place. If injectors arent tuned for...

There is a noticeable difference just from E40 OTS to E50 custom too before hpfp+inj I tell people just to skip paying hundreds for the OTS/super license when I can do custom for near the same $. Just need a flash/logging license. MHD is well worth it over JB4 of course

E30 on JB4, E50 on MHD max effort I have tuned more MT Supras than most at this point and even a couple with full E85 PI stock turbo, no issues up to 550ftlb. Most are 500ftlb at least.
