Tuning E85 on a Subaru WRX\STi

Postby Matt H » Fri Dec 16, 2011 10:58 am

Hi Guys,

Need to tune a car on E85, just a few questions really.

What is the basic process ? E85 has a different air to fuel ratio, so do you need to adjust the O2 scaling ? I have pulled a map off of a WRX running E85, and the car has 800cc injectors, yet the injector scaling says they are 353cc, latency has been ramped right up too, for example a stock car has a latency of 0.68ms at 14volts, but the E85 tuned car has a latency of 1.16ms at 14v.

The O2 target maps are also still in gasoline afr figures and no changes have been made to the O2 scaling either.

Any help on tuning E85 would be greatly appreciated !

Thanks
Matt H
