Update on total engine timing

Yes and No. If he is running an MSD Grid the distributor will be locked at your desired timing event and the grid will imitate the timing curve to your programing.
I’m well aware of how the MSD grid works. Same as the digital6 programmable that I use. As well as any other computer controlled timing setup that uses a distributor where the distributor has to be locked, and timing sync set at some arbitrary number, then the ecu runs its map. The problem was he only said “distributor is locked out” and left out a bunch of other useful information.
