Say whhhaaaatttt?????

What you say is mumbo-jumbo.

Either way, you can't do OBD-1 with that OBD-0 ECU. Ask yourself this question: Does the MSD box have a reluctor ring in it with a hall effect switch? (that is a big N-O!) You need to use the stock distributor and don't waste your time with the MSD ignition. You do NOT

 

What?

And no, the DPFI td-01 distributor doesn't have a CYP, Cylinder position sensor.
You're going to need a td-02 Mpfi distributor.

People have tried modifying the DPFI dizzy, but it will always throw a code 9...and go into limp mode whenever it decides it wants to.

Also, the stock coil is good for like 400hp....I don't know why you have a MSD external coil. Sell that and make some money.
