After getting a really good stock OS baseline for my supercharger I finally took the plunge and converted over to a 2BAR tune with OS 01250003. Aside from extreme richness when I get into boost it's running pretty good just cruising around. I'll have to sort out the Boost VE table over time, but that was expected.

Q1: Does this MAP calibration look ok?

To get my new MAP calibrated I used higher values than the COS guide talks about. When I used 188, I got 95 kPa, and 190 gave me 95.5 kPa. Not even close to the 99 kPa I was getting with the stock sensor.

C6301 MAP Sensor Scaler: 94.4
C6302 MAP Sensor Offset: 10
Old Sensor Reading AVG (key on) - 99.1 kPa

C6301 MAP Sensor Scaler: 195.6
C6302 MAP Sensor Offset: 11
New Sensor Reading AVG (key on) - 99.3 kPa


Q2: Does OS 1250003 support the N20 Monitor? I see the option on the PCM input, but no ve enrichment/timing options.
