Playing with the new updated for JB4 got that Fuel it Kit and E85 going on after quarantine. It hits hard from a dig traction issues even on the R888Rs 295s. Spinning hard no brake boosting or launch control. 0-60 3.85 seconds. On Map 3.

Anybody else playing with it? I cant wait to get the E in there and try Map 5.

See attached Terry and the Fuel it Z4 are making almost 500 whp without a flash. Pretty impressive. Bottom two pics.

I'm running the new firmware on 93 fuel and 19psi, very good pulls and consistent, better than the old firmwares, the only issue I face is the boost spiking after gear shifts, especially if I manually shift, I'll hit 28psi easy and alot of the times will limp later on.

Im pretty sure that spike is when the throttle is closed and is normal. Its not a true spike.

Affirmative, now the only issue is, that clubbed with the CatlessDp, and you directly go into a bad limp mode, no boost and when that happens your tuning halts, you have to reset the codes and drive for a long while until limp mode is gone.
Whne the same spikes occur on the stock dp, I never get the limp mode.
