Just remeber that raising the Values in the Knock tables de-sensitizes them and lowering them sensatizes them even more than stock.

 

I found a potential problem, I think. I logged the MAP output in the scan tool with the key on truck off and had 100kPa. I tracked the cell in the tuning tool on the VE, it showed me 400rpm (not running) and 30kPa. I started the truck, at idle the scan tool shows me 47kPa, the tuning tool tracks the RPM column up and down but is stuck on 15kPa row. If I stab the throttle and get up to 100kPa on the scan tool (and mechanical boost gauge to verify) I see the tracked cell sweep from 15 to 30kPa on the VE.

The tracked cell sits on 30kPa in the tuning tool with the key on truck off, while the scan tool shows 100kPa. I plugged the stock 1bar MAP back in and just set it on top of the manifold. I scaled the stock settings back in and turned the key on truck off. The scan tool showed me 99kPa and the tuning tool tracked the cell at 30kPa. I think there is a disconnect between what the PCM sees from the MAP, and what I see on the scan tool. Could this explain my problem, and how do I correct it?

Thanks
