I removed the EGR and AIR Pump when I put headers on the LT1 corvette. I followed a B body EGR Delete that was generated by EEHack online tool. Just compared the bins from a normal LT1 Y body and tried to get everything related to the EGR / AIR pump system. There were too many other related items to check all the differences so I might have missed a couple or so.
When I ran my logs I noticed I was getting an EGR duty cycle on the graph. After seeing this, I zeroed out the EGR Spark Advance Correction ( I missed that one and added it). The spark advance shouldn't happen any more.
Is there something to stop the duty cycle of the EGR? It shouldn't be calling it all. I put the maximum RPM to 0 and the minimum RPM to 6500 as in the tool generated bin.
