I recently installed the new quadzilla v2 and I had set my turbo timer up for time instead of it being based off EGT’s because I haven’t installed the egt probe yet. It worked for 2 days and now it will not work. What do I do or need to check?

Might double check both the red wires. The ignition wire to the cab fuse panel might be weak. This wire is needed to hold the engine running. It back feeds ignition circuit and keeps the engine going till the Quadzilla drops the ignition then it shut down.
