Default Stays in closed loop at WOT

Got a car that won't go to open loop at WOT. It is in open loop when cold, then goes to closed loop when it should. Stays in closed loop after that.

I have checked everything I can find to check. Any ideas??

I'll have to check the logs again, but I believe it was #22.

I just checked the log and it is in 22. For one thing, FlashScan indicates that it is in closed loop at WOT - every other car I log shows correctly (reffering to the indicators on the dashboard) - and more importantly, it won't take fuel when you change the PE table - it won't richen up no matter what.

I don't think so - I'll check. Is that a good one to log all of the time?

Edit - Nope, didn't get that one.

It will help closed loop will allways be 14.7 and when the car transitions to open loop you will see the Commanded AFR change ususally 14.7/PE multiplier will give you what the commanded AFR is supposed to be.... Can you send me the log
