I got much more then just Blaster Coil under the hood, but still it sometimes work very poorly and next day it works just fine (next day is almost always dry and mild temperature weather). And again, when reving from 3500-3800 to 6800-7000 it hesitates. I gues that I need an ignition triggering system which wiil understand an EFI to CARB change on board and MSD 6 isn't one of it, it's just a ancillary system that improves overal combustion characteristics, not more.
So the simpliest way is to change distributor on a carb one, with vacuum advance, purely mechanical - ?
Remaping an ECU is quite a good choice if there's carb maps and equipment available to do this work.
Rhinoman, I'm driving on stock EFI dizzy on carb currently, and would love to remap my Sammi's ECU for proper carb timing, but it's practically impossible in my country. Easier and cheaper would to chip-up my A6 2.6 Avant from it's stock 150bhp to 178bhp (which is done) than my Sammi.
Anyway, when I'm done with my ignition problems I would deffinatly go to one of MSD boxes!
