LBZ ECM dead after reflash & recovered

[Cougar281]

Ross and Paul, just an FYI, you might want to remove C2201-C2206 from the LBZ ECM calibrations. If you change them (I only changed C2205 to 4V, but I assume any of them would have the same result), and after the cal flash, the ECM was brain dead. No crank, no guages, Tech2 just looked at me like "Yeah? And?". V2 didn't detect the ECM, just the TCM & GPCM. Fortunately EFILive was able to recover the ECM and it's alive again. Apparently there's SOMETHING that allows the ECM to know something's changed and kills itsself.

was that in your swap?

Only in so much as I was trying to get the ECM to be happy with the gasser pedal until the LBZ one arrives. It's ticked even with the pedal DTC's disabled, and changing the voltage in the Pedal diagnostics results in a dead (but recoverable - at least in my case) ECM.

Yeah the way those DTC's report in the Bosch ECM's is weird. Like there might even be more tables that deal with DTC's that Ross doesn't know about.
