Late DME in early car

[skyhawk5421]

I know it's possible, and it's been done many times, but does anyone have problems with it? I ask because my 84 n/a does not like the late DME and AFM at all. The car will run 100% with the late stuff, except sometimes it starts freaking out and won't rev past 2200 rpms with out some crazy stumbling/backfiring. Sure makes it interesting to get on a highway

I've tried two DMEs, one stock and one resoldered, and two AFMs both tested good as per clarks garage. So the problem must be a compatibility issue somewhere. I've read people reccomend switching to the late ICV with the swap but I doubt that would make the car run great one second and terrible the next. Switching back to the early stuff cures it every time

Any Ideas?

I ran my early for a bit with a late dme/afm and i recall it did finne. smoother idle and it ran smoother. BUt then again that may have been bc the late AFM was in better shap then the Early AFM as the contacts on the early AFM may have been worn

Mine does too and that seems to be common, my gas milage seems to be better with the late stuff as well. I just don't drive with it because I like being able to get home
Damn there are a lot of smilies on here
