Re: Engine pinging when towing
Its an MSD dizzy. I am running it straight out of the box as recommended by Crow Cams for my camshaft. It has 20 degrees advance from the factory and has the heaviest springs installed. It has just been on the dyno. I cant remember what he said the initial advance was, 12 degrees or therabouts I think. It also pings a little bit with the air on at the same speed (no trailer)
