Ever since the beginning of this month when the first Bay Area (California) E85 station finally opened I have been working with E85.

I've been through probably about 6-7 tanks now and I am happy to say I have the E85 pretty much dialed in now at idle and cruise.

Idle Trims / Timing / etc: (notice the trims compensate when the fan switches on, you can see this with the drop in volts)



Idle AFR (closed loop) / load / airflow / etc:



Cruise Trims / Timing / etc:



Cruise AFR (closed loop) / load / airflow / etc:

 

cant see **** captain!

 

Can't see the graphs?

 

Looks good Bryan!

 

haven't you tried leaning your closed loop afr? on some threads i have read they are setting their afrs around 16-17.

 

I did when I ran normal gas. I switched it back to closed loop for now. I will be messing around with open loop cruise with E85 here soon.

 

are u finding different latencies with E85 or just scaling?
