    GM E67, changed to 2 bar MAP sensor, can't get MAP reading in VCM Scanner

    New to all of this, so please bear with me.

    I changed the MAP sensor calibration to 200 kpa, and extended the VVE to 200 kPa. But I can't seem to get any MAP readings in the scanner. What am I doing wrong??

    2.4L Ecotec made 340 WHP on a Dynojet with 10 psi and E85. AFR's are in the 11-12 range at higher RPM and about 23* of timing. Idle is a bit wonky but runs pretty good at the moment otherwise.

    Logs and tune attached. It was a quick tweak to a stock MAP so the tune is pretty rough but E85 doesn't seem to care.

    Can anyone provide any insight??

    Thanks.

    Easy thing to do is remove the channel, re-poll for supported parameters and add the channel back in. See if it starts working again.

    I removed MAP and then added a 2 bar MAP channel that found. Did I miss the repoll step? Where is it?
