Running into an issues where after I re flashed with the 1Bar Enhanced MAP OS my VE/MAP histo is only reading in a linear way. Its reading that at 800rpm idle im in the 15 cell. When I accelerate it only shows data in the 15 cell all the way across the rpm range. It was working fine yesterday and the only thing that changed in the tune was the MAP OS upgrade. Im sure its something silly im missing. But when I uploaded the previous tune without the OS Upgrade its reading the same.. tried a restart among other things.. And I did write entire for the change. Im at work so ill post up a log file tonight. As a side note, when attempting to VE Tune if I fail all 3 MAF Codes on first error the truck will not start and run. If I fail the P0103 it will start and run just fine, if I fail the P0103 and P0102 truck will start and idle but dies when put in gear. If I fail all 3 truck won't even run. Anyone else have similar issues? Its a 2000 Chevy Silverado 1500 5.3l 4x4
