Re: Swap Startup: Stumbling

They were supposed to tune it as a manual but honestly they are not doing a very good job of making me feel comfortable about the tune as they didn't even turn the fans on. The TPS checked out ok 0% at idle and 100% at WOT.

It has 02 lambda which always reads 0, 02 voltage which doesn't tell you much, fuel % trim which was 0.8% on bank 1 and 1.6% on bank 2 (no idea what that means), and calculated load value of 2.0% (no idea what that means). I want a AFR reading like 10:1, 12:1 etc but don't see that. I hope that 0.8% is not the real AFR reading.
