Swapping z4 for SA ecu??
I'm currently running a z4 in my 94 wagon with a few supporting mods its set to 16 psi boost and is running ok but i've been offered an sa ecu from an early sti, been looking up and it has a higher boost limit as standard just wondering if i'll see any gains from swapping the two out or best to leave alone?? by the way its on a td05, sti6 top mount, headers, full decat and walbro pump, blitz induction and pfr7b plugs. Also got a set of 440's not fitted (dont know if they'll work with the SA ecu or not)

Don't waste your time looking for another ECU when what you should be thinking about is having your ECU remapped. With your current setup those 440's would be icing on the cake and give you a completely different drive with proper power.
ESL 'Live' is the right solution for your classic allowing a tuner to fully custom remap your ECU exactly to your engine and and mods characteristics. You Z4 ECU is roughly 260bhp, so with the 440's and remap you've got to be looking at 300bhp+. The SA ecu isn't going to give you much more than you already have.
With an ESL daughterboard and remap fit the 440's and your P&J will come alive. It costs from £550+vat.

id go the esl rout
regards the ecus, the sa is better.
the z4 is 12.73psi the sa 14.94 and was on the v1 sti.
if your going down the esl rout, sell your ecu & pick up a cheaper one.
