Hey guys I recently was told about a Cobalt 2.5 bar map sensor that is good for 20psi. The part number is GM 12615136 I cannot seem to find anything on it. I was wondering if anyone has run this map and what do set it up as 2 bar or 3 bar? Any help much appreciative. Thanks :hihi:

That's the new part number for 12580698, and I thought it was only 2 bar. If it was 2.5 Bar, you would set the table up to 2.5 bar, not 2 or 3.

Does a 2.5 bar sensor even exist? I've heard of it but can't find any SOLID information about it. It seems everyone is confused with this part number.

I would guess it's really a 2 Bar sensor. The 12615136 is the new part number for 12580698.

I believe that is incorrect. A 2bar map sensor will only read 1bar of vacuum and 1bar of pressure.

A 2.5bar map map sensor will only read 1bar of vacuum and 1.5 bar of boost.

So a 2 bar table would need a 3 bar MAP sensor and a 2.5 table would need a 3.5 or 4 bar map sensor to set the map table accordingly and accurately.

For a 2 BAR MAP sensor, you would set {C6301} to 190 ish

This is a 2 bar MAP sensor.

There is a lot of mis-information floating around about MAP sensors. Especially the 2.5 bar sensor. I looked for one but never located it. I'm using a 2bar up to it's limit and PE beyond its limits. A sticky with part numbers and descriptions would be helpful for guys looking for a 2 or 3 bar MAP.

Does the 2.5 bar MAP really exist?

What about using an LB7 Dmax MAP sensor?
3 bar

According to that sheet it is a 3.3BAR sensor?

Hopefully I get a chance to look at it later.

Same one as on my Dmax trucks. Maxs out at 37psi MAP or 32psi boost. Should work well. Uses the same connector. Pretty common part in junk yards. I have a spare one here I plan on using in my 6.0l LS turbo build.
