Like the title states loaded a base tune on the car from bama JUST to get it to idle while I wait on my tune from justin @ vmp, just accounted for MAF and fuel changes and idled only (car never moved, no load, period). Started it up, idled flawlessly, let it idle for 2-3 mins, shut it off. Fuel was at 14.7-15.6 AFR at idle. Came back later, added 4% fuel on the handheld just to richen it up a tad for some idle data logs. Reflashed it, car won't start. Changed back to default fuel on the handheld, re-flashed, same result, reloaded the base tune onto the handheld from the tune on the computer, reflashed, won't start.... Car has fuel and spark, plugs look perfect (except for the fuel that's not being burnt from the attempted starts).... What in the hell is going on? Ideas? Vacuum lines are all connected, frps is working......
