I've found two Gm 2 bar MAP sensor numbers. 16040609 (old number) ... 12569241 (new number) Are these the numbers for a 2 bar GM MAP sensor that will mount the same way as the stock 95 LT1 MAP sensor and use the stock pigtail? If not, what is the right part number?

 

12569241 should work. You can also look up the map sensor for a GMC Syclone/Typhoon truck.

Thanks for replying. I'll order one and fight the programming battle. It's a daily driver so I'll try to discover if having 3 or so different values of boost (1 bar +) spark retard hurts 'normal' driveability.

So that's where the pressure vs voltage table went to. I knew I'd seen it but couldn't remember where. Now I won't have to break out the test gauge, tubing and bicycle pump to make one. Many thanks!
