P75 Timing Maps
I was wondering what the stock P75 (LS) ECU's timing maps looked like. The reason I want to know is so that I can tune out the timing advance found during low boost while retarding map voltage using a piggyback.
Fuel maps would probably help too, but I really only need the timing map. Any more helpful information would be appreciated.

Wow, thanks a lot for the great info guys.
As far as pulling timing, I'll be using e-manage. I'm not really interested in going from OBD2 to 1, and I already have an e-manage unit anyway. I really only plan on running about 10 psi, and I figure that doing the 'hack', if I can modify the timing, will be alright for that small amount of boost.
