Does this mask/ECM use a crankshaft position sensor? One of my friends got a TBI and he says it has a CPS. DIY-EFI archives (GMECM part) don't say anything about this ECM. I thought it was basically the same as a 7747 or 8746.

Some of the real late stuff uses a crank sensor, but nothing that I know of used them, and a 747, or 746.

747, and 746 are very similiar.

Hmmm...then I wonder what he is calling a CPS. I didn't think it had one. I'll get him to send me a pic of his "CPS".
Thanks, Grumpy. You da MAN!
