BUMP.

And that would determine if it's popping caps or not? (Sorry for that gangster talk, ha)

I bought an OEM computer today and should be here tomorrow but I'm scared to test it out as I don't want to wreck something that works perfectly well.

if you cant find a short to gnd on any pins, its relatively safe to connect a stock computer.
They are heavy duty units, but a shortage will kill them.

Update:

Tested the OEM computer and the car runs PERFECT! Roughly 14.8-15.3 at idle and into the 10's at WOT.

Time to save for a standalone, 1000's, cams and 25psi.
