Has anyone had problems like this after a similar effort?
My mechanic installed the TTS-Performance stage 1 supercharger kit in my 2017 Rocket III roadster. We used TuneECU to load a map file supplied by TTS-Performance into the bike. The bike initially would not start. The engine would not turn over at all when the ignition was on. After a few attempts did and seemed to run fine. We find however that it does not always turn over. My mechanic noticed the starter button relay grounds to the ECU and if he bypasses the ground it starts. He also noticed a similar situation with the fuel pump relay (grounds to ECU and sometimes doesn't work as though the ECU is not providing ground).
We are don't know if it's the ECU, the map file or something else all together. The ECU part number is 1290216 and we've seen other ECU's for rockets a bit older for sale. If we need to replace the ECU we're wondering if one for an older bike will work...
