Thread: E85 hard start in mornings or after sitting a while

I put 60lb injectors in my 04 gtp and its running on E85. It runs pretty after changing the ifr table but it has trouble starting. I've tried to cycle the key a few times before starting to see if that was it but that didn't work..

Is there any table in dhp that I can enrich/lean out the start up afr??

If you mean offsetting the ifr table for the new injectors then yes I did that. Was just think maybe there was a commanded enrichment value for start up based on temp..

Well car is finally back together, months later... I'm gonna be messing with this soon.. I've got the wide-band in it now so hopefully that will help me figure this out..

Untrue.

My car starts up instantly all the time.

i was just saying that anyone that i have seen put like 60s or larger in a car seem to take alittle longer to start

I have 70's in there now.

No "Tau" (see megasquirt manual) control so fuel trims are slightly off until it warms up completely.

If this is a function of E85, I cannot comment as I have no experience with the fuel. Only E10.

Well the car is alive again... Hopefully will stay together awhile..

One thing that's odd is the heads up display doesn't work now. Not sure why.. didn't do anything to the car to disrupt that other than the battery being disconnected for a long time...

Went out at lunch. heads up display is just the typical spring failure.. just one more thing to fix..
