Jim and Group. As a ginny pig customer, I can tell you that it has
worked on my MSD 6AL for just about a year, with no problem.
Before this I tried everything including various "fixes", that reads
expensive, and only a modern tach worked, but did not look right.
Now I have a tach that looks right and is accurate. Lots cheaper also.
