Thanks for the replies!

Working on a '58 Impala with a 5.3/4L60E swap. Using an HPI harness, no provision for the factory 4L60E neutral switch on the transmission (driver side plug). ECU is P01 01 Silverado. It appears...

I never said it was in the tune, nor did I think it was. As I said if it were my own personal car I wouldn't even care about this. I was looking for answers as to why it would exhibit this oddity...

Not my car, but I'm working with an LS1 swapped Porsche 944. Vehicle runs well and has been dyno tuned, and for the most part has zero issues. However, the vehicle has a battery switch on it. It's...

The driver demand table I made was experimental. I realize there was a big step. With the truck on a dyno I was trying to at least get the throttle to not shut down during a pull. With stock mapping...
