Hey guys, so I have heard of this problem and have done many sensor add ons on LT1's but this one is the first I've had an issue with. Sensor reports proper E%, PCM sees it, no DTC's but trims out bad, mainly at idle. Once rolling it seems fine and WOT oddly enough is hitting Lamda target on the Dyno. But at idle it acts like it doesn't want to change Stoich to E%? Eventually gets a lean code. Anyone else run into this?
Tune 9.hpt
idle trims 2.hpl
Thanks
