Dynojet 224X user's inside please!!!!!
 

Guys-how are you getting a good RPM signal using your 224X. I'm pulling the signal off the pink wire on the coil and around 52-5500 it loses the signal and goes to speed. My datalogger shows the pulls running to 152 and the drum says 142 and where the pull goes from rpm to speed is the max power it shows. This seems to be an issue around 800 rwhp+. Does anyone have a fix for this? Any input is appreciated-thanks!

I've had better luck with the input that hooks a plug wire and has a clip for a ground. I had the same issues with the pink coil pack wire, it was very irratic at times. 224xLC here.

+1 for input that grabs a plug wire, but I have had a few cars that were just very difficult with either. Moreso vettes for whatever reason. DJ224.

Try plotting RPM on the Y axis on a secondary graph with time or wheel speed being X axis
