**RPM needle bounces crazy at 6k rpm and goes back to 0**
I have a 00 GSR with a JDM GSR engine swap. Today I installed my Hondata S300 and now my RPM gauge is not working correctly. We installed the GSR base map and my buddy who knows about HONDATA took a look at it and made some changes and still couldn't find the issue. We even uploaded a JDM Basemap and had no luck. I do have an ITR Cluster with the GSR green back plate. With my stock p72 ecu the RPM gauge works perfect. With the Hondata the needle freaks out at 6k rpm even though the car is still pulling in gear. Does anyone know what could be wrong?
Thank you
