Hi All

seem to be getting some issues with the ignition and throttle position going all mad when data logging giving the car a surging type feeling when running at a set speed say 30mph with constant throttle. It is a e40 ecu being used to run an LSA engine with a converter for the 24 to 58 tooth configuration. Any suggestions on what could be causing this would be much appreciated have a data log if anyone would like to look at it.

Thanks Andrew
