Well ever since I did my last round of AutoVE tuning my AFR has been acting up. It happens mainly at first startup, coming to a stop or after driving and putting it into park. The AFR will go rich for some reason, like 12.5-13.1 and stay there for about 30secs-1.5 minutes, then it goes back to normal.... It has thrown a bank 1 and 2 rich Engine code. I just trired lowering the VE table in the Idle MAP ranges (30-40) by .95 and it seemed to help a little bit.

Any help will be appreciated. Do you think it will work it self out, I mean do you think the STFT and LTFT are just taking a little while to learn?

Thanks in advance.

 

You should post up your tune. It might be something in the park to drive enrichments. Can't really tell ya without seeing the tune honestly though. A log file of the run would be nice too. Hopefully its something easy and not mechanical

 

Well I messed with it some more last night after reading a couple of thread and I lowered the (400-800, 30-40) cells about 10% after comparing them to the stock file and it seemed to help. I will post up a tune later on today during lunch.

It better not be anyting mechanical, the truck on has 38k on it and it is basically stock.
