Question about MAP sensor settings

Post by kotasucks »

I recently upgraded my map sensor to a Bosch 0 281 006 077, all of the posts I can find don't mention this exact part number, currently I am running Scalar A - 296 Scalar B - 0.22 Offset - 5.444 in the map (values taken from a post on MSF). as it sits I'm sitting around 0.1-0.2lbs of boost KOEO, I'm just wondering if anyone could chime in with recommendations or advice on what offsets to use.

Yes this is just a reiteration of the old Bosch 3BAR MAP sensor, so you can use offset 5.41, scalar 1 = 65.78 and scalar 2 = 1
