You mean it's locked out,no timing adv mechanism's inside right? Lean burn dizzy' is also like this and has a magnetic pickup. Possibly another part's source?
I'm planning on using my lean burn dist in my 400 to work with whatever inj system I use. At least it will work with the megasquirt. Not sure about the GM tbi though.
And I found a chip burner for about $80..So now I can source all the GM tbi and simply change the chip to a custom burned one!
