EDIS maps

[Dicko4]

Does anyone have a map for a 3.8 or 4.2 with Webers

Don't know of anyone who has EDIS/Megajolt with a Weber setup. I would start with a standard map and take the car to a rolling road and let them tweak the timing. Hi-Tech Motorsport did both John's (kingzetts) and my car. Let us know how you get on and add the resulting map to the Forum thread.

I agree with David. Since Megajolt only handles ignition, not fuelling, a map that works for SUs should also be in the right ballpark for any type of carb. It should at least provide a good starting point, but given all the variables in an engine - exact compression ratio (how many times has your head/deck been skimmed before,you had the car? Not many of us will know that), exact timing, state of wear, and of course the different nature of modern fuel compared to 1960s fuel, I think anyone fitting Megajolt or any other mapped system would be wise to invest in a Rollin road session to get the very best out of the system. It's not actually that costly, around ?200 IIRC, and only takes a couple of hours or so.
