Those of you on e85 having issues with cold start...
Curious why your car takes a 5-10+ cranks until the car fires in 50 or less degree weather with the car completely cooled down?

Here's the simple fix using hptuners

Depending on your car/climate, additional or less fuel is needed.

Great success!!!

 

Borat? Is that you Borat?

 

Shouldn't your stoich value be closer to 9.85 since you're on E85?

Yes

This is just showing what table needs to be changed for cranking fuel

 

Gotcha. Congrats on getting her to start right.

 

Yeaaaa could've used this last winter when trying to start the car for 10min in the snow on full e haha

 

I'm sure Bryan could of had it handled for you if you mentioned it.

He's known about this correction long before I even started tuning for E85.

 

Oh I'm sure, but being 2hours away in the snow and not having hptuners didn't help haha it was a great learning experience. But even recently in Texas around 50-60 degrees having some stutter.

 

Just talk to the man

He'll have it handled

 

These tables don't exist for the lnf ecm. There are other ways of compensating for cold start issues on lnf's with e85 though. Our winters up here in the northeast can be brutal yet I've never had a hard start with e85 in my car with my calibrations..

 

Amazinggg now there is no reason for me not to make the switch right before winter
