Been trawling the net and made a discovery, I already have sequential injection Seems Mazda changed it worldwide around '93/'94.
Checked it here http://www.madracki.com/miata/wiring.html
That should make it easier to set up on my MS3 + 3X.

2u to InjA
2v to InjD
2y to InjB
2z to InjC

 

Indeed, it was only the early 1.6 that got batch fuel, every single MX5 from that point got sequential injection. (that includes the 'low power' 1.6 motors).

 

cool. i did not know that.



/sarcasm.

 

All are wired for sequential 94+, and 93 with CA emissions.

 

Check this guy out, he's like Al Gore or something!

All joking aside, sequential is very, very for the win... my brothers car (93 w/ a 1.8 swap, BRP mp62, TDR IC, DIYPNP) Got a massive bump in mpg going sequential, it runs a shedload smoother everywhere in the rpm range too... totally different car. Anyone w/ a DIYPNP should get the sequential module, run the wires if its a 1.6 car... the upgrade will easily pay for itself.

 

Huh, perhaps this endorsement can get me offa my *** and get the 3X working.

 

Yeah, I've borrowed Brain's inj timing map for my car and my brothers both... You will notice a difference
