So I have a feeling that my mychron isn’t reading accurately. I have it hooked up the correct way according to the on line manual. Is there a way to test if the leads are possibly bad or someone I can send it to to have it re calibrated? I have a new one on order but need this one for my second kart.
 
Mychron is all i know . I don't think they supoort it any longer .
You should call and double check with them .
 
Whats not reading correctly? RPM or Temp?
RPM. I’m running the same gear ration to my team mate and have identical prepared engines and only weigh 9 lbs difference and we have a 1500 RPM difference. I could see 2 or 300 difference due to set up and stuff like that but 1500 seems like a lot lol
 
Never had a 3 . Can you change the rpm wire out , with a new one ?
1500 high or low ?
Does the idle rpm appear correct .
Sensing off the plug ?
Temp and rpm bundleded together causes problems .

Yes it can be switched and I’m going to do that. Also the temp and RPM wire were bundled together and I am going to fix that as well. Hopefully those 2 things fix it
 
I don't think the M3's are supported any longer. I had a M3 that the temps were way off and was told no parts available for it to fix by Mychron. Id recommend just getting new gauges
