i have a jap 94 wrx would changing the old ecu for an sti ecu make any difference and has any one got the web address of the dawes device cheers

 

Not sure, the only possibility is an ECU from an STi 1, 2 or 3.
But I wouldn't recommend it even if it works initially as the STi Internals are alot stronger.

 

PMR,

I've got a 94 WRX (240PS). The std ECU was a 2C. Last night I fitted a Z4 from a 96 WRX (260PS).

Now with my full Magnex Decat, induction and Millers Booster, it's running 1 bar loadeded in 4th/5th, and it's still learning!

Fits straight in. The equivalent STI ECU's are 6K(STI 2,3) and 7K (STI RA).

These are the daddies and I'm sure would be fine in a std. WRX as i'm not convinced that the early STI's had much different under the bonnet.

Happy hunting

Daver

PS If you find any 6K's, let me know where!!
