Dwell Control

[Ward]

Most DIS systems have two inputs, generaly  Cam and Crank, You haven cited
which DIS system you are using and how you are trying to use it. I sounds
like you are trying to replace a dist sys ?

Remenber the DIS module uses both sig's to sort all of this out, also the
ECM gets both signal from the engine, Cam and Crank. 

I have done this on LT1's used a crank triger from a Cad.
