In the TM there is 2 ways to adjust the timing, Timing Vs Engine Speed Map and Timing vs TPS @ RPM; Full Timing Curve Map.

My quetion is which is the best one to use to tune out Pinging or pre-ignition? This happens on aceleraion and seems to be ok at cruising speeds.

Thanks in advance.

Readjusted the timing on my Fatbob but it made no difference other than a loss of power because I had retarded it so much to try and get rid of the noise.

Buggard if I know what it is.
Put the timing back to a good map and reset cleared all learnt values and goes strong except for this fucking ticking noise.

Yeah think you are right. I think it might be a loose baffle. The bolts are tight but I suspect it's got some movement inside so tomorrow off comes the mufflers and I will strip the baffles out and see what the go is.
