I'm having a hard time starting my car after a battery disconnect on a 2006 Pontiac GTO 2 Bar SD tune. The MAF is removed and I think it's not going into speed density mode until it starts and dies around 5 times, then it's fine until I disconnect the battery and the cycle repeats. Can someone help me with this tune and please be advised that I'm not a tuning genius. I just want the MAF to fail immediately and go into SD mode so it starts easily. Thanks
gonna take a look at whats going on...
do you have a different map sensor installed?
MAKE your maf mil on second error
max your dynamic airflow not zero as you have it
also you need to write entire
I have a Cobalt SS 2 BAR MAP installed; Part number: 12615136
I set 101, 102, 103 to maf mill on second error
I set dynamic airflow- high rpm disable to 3600 and high rpm re-enable to 3500. Is that right?

Can you explain how to make the MAF fail at key-on. My car is very hard to start when I reconnect my battery which I think is caused by the MAF not failing at key-on and it's not going into speed density until around 5 tries to start it. It just starts for a second and dies.
did you make the changes we told you about, and also if your Map sensor stock or changed?
does it work on MAF i see you maxed your injector IFR, what injectors you have in?
sorry make it mil on first error for the maf under diagnoses
make sure you do a write ENTIRE not just write. under flash select write entire.
I have Magnacharger TVS2300 60lb green injectors (they came with the blower from the factory). I have a Cobalt SS 2 BAR MAP installed; Part number: 12615136; I made the changes and it started on the first try (it never started right up after the entire rewrite, it always took 5 tries). I disconnected the battery for 10 minutes and it also started on the first try. I disconnected the battery again and I'll let it sit until Tuesday and try it. If it starts on the first try, I'll be very happy. Do I need different injectors? Thanks.
Here is the current tune that I flashed. Please go-over it and detail anything else that needs to be changed. Thank you.
