Another One Of Those Missfire/hesitation Threads

Yeah i have read a bit about them heard they arnt any good here,

i have been runing bp ultimate with a bottle of wynns race formula octane boost and a bit of xylene each tank and for 3 days it hasnt played but, could my rich and retard be caused by pinging due to the mines tuned ecu ?

Could i lower the base timing to compensate a bit ?

I emailed mines with the serial number and they tell me this:

Tuned for 100RON fuel

Optimised fuel and ignition maps

removed speed limiter

rev limiter increase +500RPM

hence it is not right for your car

just get it tuned properly, there is no easy way to fix the problem, proper tune or put the car back to stock.
