I have a 87 CRX Si thats been converted to OBD0 and I forgot to run the wire to jump the dizzy to set base timing. On my tuboedit ignition map I am at 21 degrees of idle at 500-1000rpm from anywhere at 20in hg to 22in hg
So my question IS
Can I let my motor idle and set the timing to 21 degrees with the timing gun without jumping the dizzy?

 

No. The electronic control is analogous to the "vaccum advance" on old distributors. If you don't disconnect it your timing will be jacked.

 

OK lets try it a diferent way. I have a 90 civic si running turboedit and I want to set the timing. I am too lazy to jump the dizzy and my turboedit ignition map reads 21 deg advance at idle from 500-1000rpm at 22in HG.
Can i just set the timing to 21deg advance with the timing light without jumping the dizzy?

This has NOTHING to do with vac advance distributors. The motor is a 89 d16a1
