I had the same problem.  I went back to 6*BTDC.  He says he ended up at 5*BTDC.


So I suggest you go back to 8 or 9 and see how it does.  You may need to go even lower.


Don't ping the engine.  It will really tear it up.




Hi Jim,

reset to 8 degrees BTDC, is a much smoother drive. Did a long interstate trip and sat nicely at 60-65 on the speedo. Still a hint of pinging But nowhere near what I had. May drop it to 6 degrees and test again.

Much happier with how it drives now than before.

many thanks
