with those plugs, I have misfire from 1 bar up. Funny enough, with 1.8T coils all is fine (borrowed some) - except that I don't have them, and I bought the LS2 kit as it was advertised as a higher performance option.
In the "normal" setup for the AAN in 1.1.88 is the output voltage to the coils 5V or 12V. The LS2 supplier felt that I had to change the voltage regulator to 14.5V as they want higher charge voltages than other coils. I am starting to doubt wheter these coils can perform as advertised...
If I tried the stepper route as described by Rob, will it help?
