[Diy_efi] running E85

[Tim M]

Just wanted to review what it takes to run E85.

Vehicle was designed in the mid 90's so O-rings and
such should handle E85.

>From what I have read the amount of fuel needs to be
increased by 27%. This can be done by increasing fuel
pressure, switching to bigger injectors or increasing
the fuel map(s) by 27% if within operating limits of
stock injectors. (lowering rev limit will allow the
stock injectors to work on the vehicle I am looking
at).

Not completely sure what will happen while running
closed loop with a narrow band sensor. Will it toggle
at the correct stoich for E85? 

Spark can be advanced some. I will carefully test with
a knock sensor. For now I will assume stock ignition
will be ok.

Anything else to consider?

Thanks,
Tim
