I have the timing spreadsheet that BN880 posted up a while back, and I find it to be a very useful tool. Is there anyone with the know how to make it read from 20" of vac up to 30PSI though?
I know a lot of us have discovered that messing with the timing a little bit in vac can make a big difference in gas mileage and drivability so it would be nice if I didn't have to do all my calculations separately.
