Anyone dealt with a 3.3 bar Duramax MAP?

Yea, I have three bar sensors that'd work, have the low end resolution, and are plug and play.

The 3.3 bar Duramax sensor is junk. played with it for a year. The accuracy and resolution is not good. I had a customer going into REP on a 1514 with the tune scaled down and 1514 table maxed. Was hitting 1514 and going into REP while cruising steady state. That sensor turned out to be the cause of it. Motorola makes a nice, accurate 3.0 bar chip that you can solder into your old housing and it works real nice.

Just tried another one .. same crap ... am I the only one with this issue ?

I used to 333.33 / 33.33 calibration ..

Both sensors throw the same p0107 code and im getting a high idle as well .. round 750 when im commanding 600.

The motorola 3bar surface mount sensor is basically the same chip I'm assuming based on the datasheets from both sensors. They both have the exact same transfer function. 1.11kpa to 315.58kpa.

Wondering if anyone using these duramax sensora with any luck? I've had my efi source 3 bar come apart looking for factory 3 bar. Ctsv, zr1, duramax?

They don't work well or at all.

Stick to a regular 3 bar sensor.

Which ones work well

I've been using the 3.3 bar sensor since 2012 without any issues. Granted I don't drive my car very much, but you can try this part number and see if it is still available from the dealer. GM #12623671 along with the calibration we spoke about earlier in this thread.
