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)

 

no one have any thoughts on the ecu????

 

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.

 

SA is ra ecu if my memory correct.
Higher rev limit as solid lifters and better cams.
Looks like I am cheap for esl live if normally 550+vat

 

Simon is it better for you to have a Z4 as a base ecu or the SA if its to be mapped??

 

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.

 

Double post

 

Makes no difference as esl overides map in ecu.
Just needs an expansion slot.
Although I carry spares anyway

 

Yep... That's what everyone else charges. So you are loads cheaper Simon....by £25!!

 

and one of the best at it, mentioning no names

 

Lmfao!

 

OP defo do the above! ^^^

Pointless 'wasting' the SA ECU if fitting ESL Live. Sell it to get cash back, and then just fit any bog std cheap v.1/2 WRX 0.79bar ECU for the ESL to go into.
