Hey guys just wanted to share what happened on my first datalog. Eventually when the car got up to temp it didn't want to idle normal I'd say it would stumble like it was gonna collapse but didn't. I noticed even starting the car it would idle pretty low around 600 and just getting into 550 rpm, it was normal idle for me but that is low I'd think (It's all stock except K&N and MSD Opti+coil). Now with the amazing EEHack program it told me it was ERR44 Left 02 Sensor Lean so I think I'll do the cylinder test on EEHack tomorrow. But my knock count was ridiculously high north of 6000 sometimes. There was no Knock Retard at all, and my Adv. Went up to 41 at one point on the highway so I would like to hear from anyone with thoughts thank you.
