50/50 mix question...

[jasjamz]

With a 50/50 mix, my cruise 02s were in the 400-500mv range, BLM 134 and with a race chip, 18% added WOT fuel, and 23/21 timing, no knock. My fuel pressure is 43 with the line off. Should I raise the fuel pressure to lower the BLM to 128? I can say that first impression are it does feel stronger but I'm wondering is that because its leaner than what it is on regular fuels? I don't have a WB to tune with. Car does have -8 feed 75#ers and a DP in the tank. Not using alky.

stoich for a 50/50 mix if you have e 10 (14.13) like most of us instead of pure gas ( 14.7) would be 12.00 with e 85 stoich being 9.87

I have never tuned a gn only obd2 gm's but you must be able to change stoich in your tune for the e 85 blend ?

Popped in a new 02. Cruise 760-810, blm 118, added 20% WOT fuel, WOT 780-800 no knock 20-21 psi timing 23/21.No alky yet. Same fuel pressure. I like it. Burns cleaner too. Not racing it, just a little spirited driving at times.
