lean protection e85 lambada

Post by 9queSt » Mon Mar 18, 2013 6:25 pm

When using the lean protection. It asks for lambada for protection to switch on. The help file says to enter this as an afr.

Im using e85, with no ethanol analyzer. Do I enter the value as it would be for the regular fuel or e85?

You need to enter the AFR value you want lean protection to come at. If you use E85 then you must use the value you want it to com eon with the E85.

The value I want it to come on at is .82 lambada.
This is an afr for (E85 of 7.9 to 1) or for (REGULAR fuel is 12 to 1).

The Smanager only know the widebands voltage to lambada conversion.
How does it know im using e85?

If I enter 7.9 af and it uses this on the regular fuel scale its actully lambada of .53 witch is an e85 afr of 5 to 1 way to rich.

Use either the lambda value (0.82) or the petrol AFR (12:1). The actual AFR will be something around 8:1.

The parameter is in lambda therefore the fuel specifc AFR is irrelevant.
