2 bar map?

Post by vashxj »

so what 2 bar map have you s/c and turbo guys been running in your setups? and do you just wire straight to the stock wiring if your using a custom pcm tune?

I don't know what map I got with the ripp supercharger kit but it did plug right into the factory wiring.

As said, the GM style sensor will work. Looks like the earlier Jeep sensor, but 2 bar.

Ryan in the house....... :cheers:

I don't have an overwhelming preference towards either. BUT, here is what I will say. The SRT4 2bar MAP sensors are actually 2.25 bar, which makes them good for something in the vicinity of 18 or so psi. A standard issue GM 2 bar MAP will peg out at something like 15.5-16 psi. JTEC has a fixed number of load columns regardless of whether a 1, 2, 3 bar map etc is used so the greater the MAP scaling is (e.g. 2.25 bar or 3 bar versus 2.0 bar) the worse the resolution is. For lower boost pressures I can modify the scaling to minimize loss of resolution but no matter what, the 2 bar will always have better resolution than the 2.25 bar.

Bottom line: I can make both work, but for best drivability I'd recommend the GM 2 bar MAP unless you intend on pushing 16psi or greater.

Gotta go, back to work.....
