Yeah - the stock maps are a bit choppy. I would (and do) smooth out the cells.

awesome!

now just to find the money to buy an ostrich lol

oh another question. this program is letting me adjust the fueling based off FQS position, as it is presently, would the stock FQS ignition retard values be kept? how is it coming along with your modification to allow for fqs timing adjustment too?

A lot of instability running e85 on high output ( 200-250 bhp /cyl) engines , your assumption is closer to the truth , humidity is the key variances up to 20% (on top of the 25% up front) is not uncommon, to maintain TFR.

PS: running without an e85 snsr is redonculous...

The FQS timing adjustment is there, and not a big deal. Just need a bit of time to test before I release an update... I'll try to get to it this weekend.

Not too many 800-1000hp 951s that I know of if you mean that?

When you say an E85 sensor, do you mean one of those Flexi fuel sensors that detect the ethanol content in the tank?

I suppose Mr Wayne referred to engines outside the 951-community.

Oh, and at least in Sweden E85 is actually E75 during winter time to help cold starts. Something to be aware of if you're taking a spin late in the season!

I'm guessing 72# injectors aren't big enough to run e85 correct?

10 lbs injectors can be enough, it's just a matter of how much power you want to be able to run. So the answer to your question is "it depends"

I somehow thought someone would say that lol.
I meant for running over 350 whp or so. I have a t04e 50 trim that I'd like to run over 16 psi. I figure e85 would be a good way to do that, but I'm unsure if my injectors are large enough.

do you mean a sensor to tell you the actual ethanol content?
