If you turn it off you will clear the flash kernel out of RAM leading to a brick. turn off the ignition after a failed flash. Having had success in popular tuning chassis such as the Subaru WRX STI, Mitsubishi EVO, and BMW M3, this was a natural progression of expansion in VRs repertoire of vehicles. My ECU is not SH705x so I can't use the 'sh recovery' procedure. VR Tuned products include everything you need from booster pedals, ECU flashes, and gearbox tuning to tuning accessories and complete tuning box kits. I've tried disconnecting the battery but no luck. When I disconnect the green connectors, it continues to cycle the fuel pump (but not the fans) BUT if I disconnect the battery, it stops cycling until I connect green connectors. On my last try, the ECU stopped responding While flashing suddenly it said 'programming voltage too high' so I closed the ignition and opened the headlights (did this 2 times). My CEL then began to, and continues to flash continuously, and my fuel economy has gone through the roof. Great I thought I then cleaned the MAF, and reset the ECU with Learning View to see if this would clear the CEL.

Today I was trying to reflash my ECU with OpenPort 2.0. XRT offers professional Subaru Remote Tuning Services with over 12yrs of innovative tuning experience with all types of Subarus. I used Learning View to find a CEL code P0171 engine running lean code in my MY04 WRX.
