What do you want to know about it :)

are they a 3 pin? or 4 pin?

I have a chance of a apexi off a 98sti would this be able to fit my 94wrx. quoted

will keep on looking

bttt

The Apexi from the MY98 STi will not fit your MY94 WRX for the reasons you have already stated - yours is a 4 plug ecu & the later model is a 3 plug.

The Z4 ECU map is very similar to that of the Prodrive map but has a boost target of 12.71psig whereas the Prodrive map runs 13.64psig - It has a boost cut of 15.65psig. The Z4 & Z5 are the best JDM ecu's available as they run well on our higher octane fuels and don't have too aggressive ignition maps ;)

Cheers
