When posting a KPro problem with your vehicle, please include:
- the calibration (as an attachment)
- a datalog of a problem (as an attachment)
- what sort of vehicle you have
- what sort of ECU you are using
- anything about the car which has been modified from stock which may affect the ECU (don't include what sort of rims you have nor stereo etc).
- a specific description of the problem

Most of the recent posts leave out information pertinent to solving the problem.

If you have an engine swap, please mention this. There are known problems with the engine harness from one company, which they refuse to acknowledge or fix. We cannot name the company, but I always have used Hasport engine mounts and both their mounts and harness work.
