Not really a mod, more of a repair. Had to rewire my entire Unichip harness. Apparently it sat too close to the engine block and caused a short. What a total PITA to find and diagnose.

I’m 100% back in action, all 5 tunes are loaded back onto the Unichip, and even flashed the firmware to the latest revision.
