N55 on full E85 with PS2

colt.jw · 03-16-2021, 11:03 AM

I am switching over to a custom full e85 tune and want to know if I got all the right stuff I need. Those of you with insight on an n55 with ps2 and full e85 tune please grant me your wisdom. Pros and cons, do's and dont's. Thanks.

Also, I will most likely run the stage 2+ e30 tune daily for my car and the custom full e85 tune on weekends, perhaps more often if I'm being honest.

Mods Reference:
VRSF catless dp, Evolution Racewerks fmic + chargepipe, CTS intake, Spool fx-180 hpfp, stage 3 xhp transmission flash, + I have eldor coils + gapped plugs.

Current Tune: BM3 stage 2+ e30

Soon to be installed:
Pure stage 2 turbo, Kompact EM BOV VR9, PR high performance lpfp stage 2, plus new 0.20 gapped plugs for e85.

Custom tune for full e85 done by the same shop. (caryjordan tune)

Do you really need the LPFP? And curious to see a before and after dyno, if you plan one.

I just purchased another tune today from Cary Jordan for the pure I just put in and full E85. I have the Dorch stage 2 HPFP and iirc yours has a higher output so.. I picked up this guy from FCP Euro (BMW MAP Sensor - VDO 13628644433) and I am also enabling line pressure bump for the torque on XHP app.

Steven,

Glad your enjoying your existing tune.

Need 3.5 bar TMAP Sensor, or we wont be able to go above roughly 22PSI.

No need for upgrading LPFP or EKP, good to go E85 with PS2's and Dorch Stage 2.
