Default E85 Tune

I got my e85 tune pretty squared away WOT is spot on, but on cold startup it acts like it doesnt want to start. I know this is a common issue with e85 but not educated enough as to why. What tables should I change to get that instant start like gas?

Yes it is but it doesn't have to be. From what I understand it can be corrected. I just dont know enough to know where to start.

Cranking VE will need some work to get it to light especially when cold. You also have to be careful with startup airflow.

I figured you wanted the whole Id. I'll have to get it for you this evening.
Elaborate on the startup airflow? I'll need to add or subtract some over gas?

I just want to be careful that you do not have too much startup airflow. This can compound the fueling problem on startup.
