This is geared more towards DG or Matt Cramer, but really anyone who's been in a similar situation feel free to chime in.
I have a friend who wants to upgrade his '70's truck to fuel injection. He hates the concept of batch injection so he's pretty much settled on at least semi-sequential with an MS3. My question is, for semi-sequential injection is the MS3 fine or does he need to order the MS3X card to go with it?
I'll probably wind up doing most of the install and whatnot since I've had more experience retrofitting EFI to older engines, I'm thinking a trigger wheel, EDIS and semi-sequential, and then if he wants to go full sequential ignition and injection we can convert the duraspark distributor to a single pole cam sensor or drop in a TFI hall sensor distributor and modify the "windows" accordingly.
I guess where I'm really not sure about the 3x or 3 is I see in the manual that there are injector outputs from the cpu but they look to be line level which means I'd have to build an injector driver circuit. At that point my gut instinct is telling me it's probably cheaper and easier to just get the 3x card. If he doesn't want to spring for the card, I guess he'll have to learn to love batch injection...assuming I'm interpreting everything correctly. lol
Anyway, hope that makes sense, any advice you can give would be greatly appreciated.
