We've just been down the road and was amazed that under accelartion 0-90mph and 100% load the timing is retard to 24 deg and slowly works it way up to 28 deg at 6800, however if you lift off the throttle the smallest amount between gear changes it shows 49 deg for a secound or two ( not good for nos use)

Unfortunatley it has started raining so we cant do any more testing

Has anyone data logged info like this before??
