Actually on the NF/NG with CIS-E3, the ECU has no idea where TDC is, it 
just control the timing electronically *relative* to where the static 
position of the dist. is.  On the turbo cars from that era, there is a 
flywheel position sensor to let the ECU know where TDC is.

Correct, of course - meaning that if the rivet is still in place, his 
dist. timing should be correct already.
