So I have installed the zr1 map sensor and changed the configuration to Linear = 312.5 and Offset = -11.25. Now its running very poorly and i cannot even tune my car. Am I missing something? I have attached my log file and tune file.

I'm on my phone so I can't open the file, but are your units correct in the tune (should be kPa).
Yes, Map Sensor Linear and Map Sensor Offset are both kPaQuote:

I was hoping you would show up on this thread. I ordered an ACDELCO one. Once it arrives I'll install and report backQuote:

No, you only have to change the linear and offset settings to make the MAP work.
I don't know what your other problems are. Changing just the MAP sensor itself won't cause this issue. You should probably double check that you don't have to swap pins around in the connector to make the ZL1 map sensor work.
With key on engine off, I am getting the 100kpa reading you said I should be getting. But I'm getting a "click click" noise when trying to turn the car over now. :banghead: which didn't happen last week. So, I'm thinking maybe now the new issue is either the battery or starter.Quote:
