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 65.89kPa, MAP sensor offset to -6.35kPa, Boost sensor linear to 65.89kPa, and Boost sensor offset to -6.35kPa.

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.

GM S1 Working, Not too Difficult to Install

This was a fairly straightforward install on my '09 SS Turbo with some slight changes. The harnesses are too long but they make the right connections. A long screwdriver is needed for the bottom end and some modification to the part to make it fit well there. There is only one spot for screw on the topside vs. 2 in the stock modult as these don't match perfectly either but it will wiggle in and do the job. Here's a link to a video I used to help with the install: https://www.youtube.com/watch?v=qQXsnVvEZPw&t=7s&ab_channel=JosephDiFeo

Boost sensor

As described works great so far. Seeing 25psi with trifecta tune and this sensor. The wiring harness makes everything look clean and stock.

Broken on Arrival

The TMAP sensor had 1 bent pin and the MAP sensor had the pin on the connector pop out. I just went ahead and soldered all the connections. Other than that, everything worked fine.

3 bar Bosch sensors

They work great, as do the connector extensions.

Dropped right in. Worked like a champ. As it should be.
