e85 question

[richburke03]

So I installed my new tt e85 chip and car is fast as hell and runs great. Only problem is that when I start the car now it runs ruff and my iac starts off at about 90 then settles down to 10 after about 4 minutes. Car never did this before. Any ideas?

Cold start is one of the few downsides to e85...all you can do is get with Eric and try to get the tune as close as possible, cold start is always the hardest to get right even on gas.
