    Default Log 2-bar MAP with a MAF tune?

    As the title says. I recently swapped to a 2-bar MAP on my MAF tuned car. I set the scaler to 190 but the MAP will not read past 105kpa when in boost.

    How do I get it to read past 105?

    Ok, does it not read past 105kpa in the scan tool on the gauges, scan tool actual PID information, or tune tool VE/Spark tables?

    Im going to guess its when looking at the gauges in the scan tool, with the gauges displayed in the scan tool right click the MAP guage and select Gauge Properties. On the General tab there is a box for Max, enter the number you wish to see (Id recommend at least 290 as thats the limit for the LS1 COSs). Click Ok and then open the log file, should be all set now.

    I'm not using the gauges version of the dashboard. I'm using the graph or chart version. The scale for the MAP is 0-255kpa

    When ever it is in boost, the graph flatlines at 105kpa.

    Have you rescaled the MAP part of the tune to recognize the 2Bar MAP sensor? Can you post your tune and a log file?
