E85 afr

Post by barrym »

Does the kpro v4 do any auto scaling for afr when running e85 ...
For example, when setting closed loop, do I set for the e85 stoich or regular 98 pump fuel ?
I have flex fuel enabled with the continental flex fuel sensor and see on average 82% corn juice ..

If you look at the flex fuel tab in parameters, you will see that there are configurable settings for closed loop an open loop.

For ethanol it is important to remember that the AFR is calculated from the lambda measured by the wideband. And it is the lambda which matters not the AFR for the specific fuel.
