Slight confusion on MS PnP applications

[getnpsi]

When I have clicked provided links to the guys who build the megasquirts, some are 2 plug and some are 3 plug. Are you guys (end users) reharnessing your cars or can a BP/b6t/whatever programme be implemented into a 2 plug mega-ecu and it's then plug and play from there? I don't think its quite that easy. All the pinouts are the same?

2 plug I would say is for stock style wiring and 3 plug is for a Capri harness?

Well aspires used a 3 plug and so do older not round 323's. I think auto's opf older ones did too. I can't imagine all the injectors charging system yadda are the same, that would make sense LOL. I guess my question more would be can a cars timing table and fuel table from a car that is a 3 plugg from factory be flashed to a 2 plugger ecu and then be plug and play into a festiva?

I bought mine from Lex on cp.com. His business is stratfieldautomotive.com.

Mine has a harness that goes from the db-38 connector(cpu stuff) to the stock 2 plug festiva/escort gt harness.

It also came with 3 base tunes. 1. tune for 230cc, 2. tune for 460cc, 3. tune for 550cc.

It works perfect everyday. I dd my car about 500 miles per week, and go to the track every friday. Still can get 30ish mpgs driving like an old man.

Oh yeah running the a/c too.
