Engine is a Gen 3 5.3 w/ ETC, stock computer, LSA blower and btr cam using stock style lsa rail and injectors, ZL1 lid with OE 3 bar MAP and IAT sensors in the lid. I flashed 03150003 for 3 bar SD w/ the last working file, and am getting set up for idle tuning. I started with the 288 scalar and no offset for the new MAP sensor. After making a few changes in effort to get it to idle, after the last flash it wouldn't start. It smelled like gas and had my wideband reading 10.0. Looking at the scanner, suddenly my MAP is stuck reading 105 KPA which makes sense to why it isn't starting. If unplugged, the pid now reads 0. I went back a few files to make sure it wasn't something I recently changed, but it won't move off of 105 for anything. I even flashed the base tune from the old OS to similar results, now reading at 40 KPA with the original scalar for the stock map. Has anyone else ran into this? This is my first experience with COS.
