A 99 black box ecu is for a 4g63 so no it won't work on a 420a. You need a 420a ecu. If it's different years then you can rewire the pins but it's much easier to just find the same year ecu your car needs.
Hey man... Your best bet with dealing with that 420A is going to be finding a used megasquirt and someone that can help you load a stock map and tuning it for your car, or build one.
I was a little undecided between MS and FIC. What's a MS go for used? im on a budget, but im doing well as of yet. The motor is torn down and im rebuilding the top end. OBX 242/242 cams -AEM cam gears -2.4l lifters and rockers -crane valve springs with titanium retainers -cometic head gasket -ARP head studs also porting intake and TB.
im looking for a controller of some sort.... id like to learn a bit more about the AFX from howell.
I bought my MSIIv3 for my '78 Camaro with an LS2 swap into it for $250. (You can buy them new and assembled for like $500??) If you're not running boost or nitrous, which is an awesome application for the 420a (Nitrous anyway). Don't bother with the head studs... ARP bolts will do just fine (my 2c) A MSII will do just what you need... don't forget to either buy the stimulator or find someone that has one so you can test out the ECU functions... If you end up building your own... there is a lot cool extra features you can build into it. (Launch control, boost control, Nitrous safety's... shit like that) I've never been able to afford AEM ECU's (I'm sure they're really good though)

Here's all you need to know: Stay the hell away from Gary Howell. The man is a recalcitrant jerk-off with absolutely no regard for his customers. If you need more evidence to that end, just search.
Unfortunately that piece of advice is becoming increasingly common, which sucks because it sounded like a must have. I mean I have an extra 97 ecu I could send, but I'd rather not deal with any bs( other than from my 2g, which is par for the course....
