For2.5 bar MAP sensor 12580698 try this:
MAP Scaler 207.65625
MAP offset 9.00
I think that is right from the factory tune settings for the ION Redline.

Tune it or lose it!

Do the 2.5 bar sensors read okay to 20 psi boost on our cars ?
I tried a 3.3bar sensor and it was a waste of money, couldn't tune VE off boost with any consistancy..
Back yard boost
347+ T76 = 770 rwhp 10.96 @ 135 mph
^ I want to know this too....time to move up from a 2 bar
2005 Silverado Duramax LLY - EFI Live Tuned
1969 Chevrolet C-10 Pickup - Turbocharged 5.3L/4L80E - EFI Live Tuned
1975 Avenger Jet Boat - 6.0L/Berkley pump - EFI Live tune in progress
2bar = 29.00psi
2.5bar = 35.259psi
2bar map values I posted in an earlier thread and 2.5bar is used in ZR1 and those values can be found in a stock file. If you need me to post them let me know

just want to know if anyone useing the 2.5 bar sensor has pushed it to 20 psi boost and the sensor reads beyond 2 bar okay.

I'm still not sure about the 12580698 MAP sensor (Now 12615136) whether it is a 2 or a 2.5 bar sensor. Anyone know what years they use them on so I can try to find a Cobalt SS tune? I was running 190/8 in my tune, but it still feels off. I'll try the 207/9 when I get home.
