Question about Megasquirt

[nocrashnofun]

As I was looking into it, I can only find the gen 2 PNP which states 87-91 E30 but mine is an 1986 early gen model. Will this still work on my car or am I missing something? I don't see the first gen sold anywhere.

Is yours motronic or jetronic?

I actually have no clue, is there an easy way to figure that out?
