It's been over a year and I still haven't figured out how to get my data logged rpm's accurate. They seem to read about 300rpms higher than the actual flywheel rpms. One way I know for sure is that my limiter is set to 7150 and I get readings over 7400 with the data logger and there is no evidence of hitting the limiter. Can anyone help me get this accurate? It would really help me dial in my car at the strip!!
Thanks
