I have been getting the ignition map ready (or something close) for when i change over to MS. I have taken the info from the Saab workshop manual for the ignition advance and placed it onto the ign table. I have realised that on the engine at present the disi vacuum is not being used and when i had it on a rolling road some years ago, the operator said i didn't need it as the engine ran fine. I was wondering if anyone has done this before and then when fine tuning the ign table, they ended up as if they had removed the equivelant of the vacuum advance?
The engine is a 2000cc Saab lump with K-jet, 272 deg cam.
