I am new to this forum but follow since 2009 the other N54 ones, bboost, n54tech e90post

My car is E90 N54 MSD81 FBO on stock turbos, my base map comes from wedge, but I edited a bit with tunerpro and flashed with bb2.0

Mod are:
E85 available
Methanol single nozzle
catless DPs
200 cell secondary cats
inlets
closed modified intake
outles
wagner race FMIC


my question is:

could someone advise me on map to use and % of E85 to maximize HP and TQ to the limit of HPFP and LPFP?
Post table content for load, vanos, spark, afr and linear throttle
Of course I will log and adjust consequently to keep trims, afr, knock, and fuel pressures under control.

Without upgrading the LPFP I would not run more then two or three gallons of E85. I comes down to how much the pump can keep up.
Pull some logs you an you will be able to see where your pumps start to dive.

Depending on the health of the stock lpfp. Some can handle up to e50, most e40, and some weaker ones only about e30.

You can turn the boost up a lot more than that. Maybe 18/19psi and add a little timing if your mix is closer to e40.

I would decide on a performance metric as to how much more power you want. Time to speed, trap speed, etc. Adding timing, boost, fuel doesn't always make for a faster car.

I know there is a richt balance between boost and timing to have the fastest car....
someone is willing to share the load, timing and vanos tables with me?
