3bar MAP scaling

Post by MPS dude »

How do I exact scale the 3bar MAP sensor (845) in Versatuner. I have found a lot of items in different forums, but the are all Cobb app.
I understand that boost has to be near 0, but which boost? How do I moniter that? Which is Scalar A, B, etc in Versatuner?
Can somebody help me with this?

set the
3 (charts)x map scale aditives : 6,353
3 (charts)x map scale base multiplier :65,88
3 (charts) x map scale second multiplier : 1

and you log it from the Bosch 3 bar map sensor pid

Thxs boloteo! And what value should the Bosch 3 bar map sensor pid give with KOEO? should this be 0 or should it be 1bar?

The sensor pid says 1,03 bar with the settings you gave me. Is that correct?

It should be very close to your barometer reading with the engine off. If you are at sea level, ambient baro should be around 1.00 bar.+/- depending on weather.

My laptop was changed (and I had built and replaced engine) and was wondering why same Bosch 3 bar MAP was now reading low on logs. Did not remember that it needs to be selected in Dashboard - MAP - Customize.
