Boost cut at 5000rpm turbo b series del sol
Hey guys so my car doesn’t pass 5000rpm when shifting gears seems to just boost cut completely it’s tuned on s300 also my speed sensor wires was rip can a faulty speed sensor cause the boost cut ? Or **** with the tune ?
Yes, if you have launch control or full throttle shift enabled, you need a good VSS signal. No VSS can also prevent other functions from working (I think including VTEC).
^^ What they said. I had this exact issue and needed to clean the speed sensor plug. It was odd because my dash speedo was working but I noticed in my datalog, it was not getting a signal from the speedo. No signal. **shrug** I cleaned the plug and she was working like intended from then on.
