I have a mychron 4 that is having a few issues. The temperature was way off so I bought a new cht lead. Well with the new one it reads 214 or so when it should be in the 60's. I have tried 2 other cht leads and a egt sensor same scenario. Hooked all of them up to another tach and they read the same 64 degrees. I took the lead off at the tach, hooked another up and it still reads in the 214 range. Is there a way to reset this thing or has it bit the dust. Thanks Kevin
