GM Stage 1 Sensors

Replace your factory MAP sensors that blow out when you turn up your boost with these GM 3 bar map sensors in just a few minutes!

PCM file update required, See "Option 2" on our ZZP LNF 1.0 PCM page.

LNF only!

Includes:

  • (2) GM 3.3 bar map sensors (good to 33psi)
  • (2) O-rings
  • (2) GM Plug and Play wire harnesses

ECU Programming

In HP Tuners, set the MAP sensor linear to 65.89, MAP sensor offset to -6.35, Boost sensor linear to 65.89, and Boost sensor offset to -6.35.

These are an intended upgrade for the 2.0 turbo Cobalt SS, HHR SS, Sky Redline, and Solstice GXP. The 2.0 LHU Regal does not need these as they come stock with 4 bar MAP sensors.

Great Product

I had just installed my new motor and the sensors didnt match the plugs in the harness, and none of the local auto parts stores or the dealer had the correct part. So I looked on ZZPs site and this was an exact match! They shipped the part out right away. Thank you ZZP!!
