I did check on the MSD sight, couldn't find anything other than running two MSD DIS-4's which seemed a bit extreme. Particularly seing as I don't want to improve spark strength, just want to add a step retard.
i share your pain but the lil evil elves from the black forest aint givin up the secrets of the ECM without a fight....i~m gonna quit on my quest for a NOS install for this reason...good luck
The J and S vampire appears to be what I need. $575 though... That being said, it is a very sweet piece of gear that would give great protection to the engine.
