2010 L99 Start up and idle issues

This is a LS swap project, 2010 Camaro L99 & truck 6L90 to into a 1957 Chevy. When I start it will run for 15 seconds then dies. If I pump the gas, I can keep it running, but it runs very rich. Once the engine temp reaches 195-200 if will idle. I have attached the current tune and scan files. Thanks in advance for any suggestion on the tune or insights you discover.

Why is your MAP sensor reading 228kpa at key on/engine off? Why is the tune file set up for a 3bar MAP - are you using a 3bar MAP?

edit: And 115lb/hr injectors? Seems you would have mentioned that if it wasn't stock. Are you sure this is the right tune file?

Stock engine, injectors, map sensor, and TB?
Test this tune.

blindsquirrel,

Thanks for taking a look, I bought the 6.2.and ECU together. God only knows what been changed over the years. I have replaced all the injectors with Stock Camaro SS injectors, so what is the correct lb/hr for stock injectors and bar MAP I just replaced the MAP sensor (Stock Camaro SS MAP).

Thanks Mrz0611

Thanks for the tune. I do not have a turbo on this engine.

do a key on engine off log

verify the map sensor part number and injectors

from the looks of the file its a boosted setup and has over 1000cc injectors setup

Will Do

Thanks SultanHassanMasTuning

It was a stock MAP Sensor. I went back to a stock tune and everything is working!
