Chris, interesting thread, and thanks for your findings.

I agree that 930s respond much better off-boost with more advance. I couldn't live with mine around town when it was retarded 4 degrees over stock - and it felt like it picked up a 1/2 liter big-bore kit with only a few extra degrees. This was done on some specific advice.

I read a little sidebar in the POC GB magazine (think it was in the 930 register section) that stated that the factory timing for the RoW 930S was 25 degrees, but I could never find it again...

I'm really intrigued by the J + S Safeguard, which offers individual cylinder knock retard and, if I'm reading it right, a built-in MAP sensor with adjustable boost retard. Oh, and it's capable of either firing the coil directly or triggering an MSD.
