Ok OK OK...............
So this is not exactly what i was looking for.
Thats more of a controller, of a controller.
It just allows you to control things in a more precise manner and the points at which things are operated.
For your application Charlie, or anyone using the stock quadrajet - its an ideal way to control the pevr valve and gives the ability to offer a way for economical tuning. being able to control at what point the carb begins to see signal for enrichment operation is an excellent way to maximize ideal fuel curve in porportion to boost.
However, not really nessacary with the holley. It can be adjusted thru mechanical means internally to the carb easier than say a quadrajet but could still be useful if you are willing to try. i dont know if I will pursue the extra adjustbility on the fly of this curve, as factory enrichment control has served superchargers well for many years and I am confident in its operation for my desired results.
for whats its worth, i dont think the ESC is good enough alone either, while it is excellent for controling timing at the occurance of knock - the point at which this happens is already too late for the horsepower levels I anticipate we will be experiancing. Any knock is bad knock - and should be treated as such! Use of the MSD BTM- weather the ignition box, or just the control unit, is almost nessacary to maximize the potential of the boost. by allowing higher then normal boost in retarded timing state, the ESC will perform more as a safety net then actual timing control. at the first sign of knock due to poor tune, in either timing to boost retard porportion, poor A/F mixture, excessive compressor discharge temps or mechanical failure, it will retard the timing hopefully before any damage is suffered.
So that still leaves me to looking for the diagram of the original factory ESC box.
