As far as i know there is no difference as i've only seen i lot of figures for the specs of the ecu.
I paid £75 for mine off here so imo i wouldn't pay more than that although i've seen some on ebay going for over £100.
If you want to improve power you could try www.enduringsolutions.com or a new website www.polarperfromance.co.uk and see if their products interest you more

All depends on what mods you have on your car.
I posted my spec on here https://www.scoobynet.com/general-te...cu-advice.html.

If you do a search for 'mickywrx' and have a look at his scooby (in the grey box where all little icons are) he is running 330bhp on a standard ecu (not sure if it's a z4 though as he has a 94 wrx) but that would be the extreme limit

cheers thats good to know as also have a 94wrx
