Does the engine crank over but doesn't want to fire?

Sounds like the ECU has got damaged in transit (but the added sports chip inside is prob okay). The same thing happened to a Polar Performance-chipped ECU I bought off eBay. Had to get Scott T to swap the chip/board over into a spare ECU.

If it IS that, then you can pick up a another doner MY93-96 4-plug ECU for about 15-30 quid if you're lucky...

Oh, and the max boost will invariably be 1.1bar (16psi), as the MY93-96 MAP sensor's limit is at 1.2bar and would fuel-cut (or is it boost cut? - can't remember) at that point.

Are the ECU codes the same? You could try putting the chip in your old ECU

Once the chip is fitted it make no difference as the settings are now in the chip. Your U8 ecu does not have a plug for the chip to go into though. It'll still work but you will have to get it soldered in. OR. Get another ecu with the plug already fitted. Some came as standard, I think in the STI's and the RA. From memory a Z5, 7B, 6K have them (I'm a bit rusty mind!). And some more too but I cannot remember.

SUBARU IMPREZA TURBO 6K ECU WRX STI UPGRADE 1993-1996 on eBay (end time 02-Aug-09 00:16:58 BST)

Impreza sti 95 type ra ECU with polar performance chip on eBay (end time 05-Aug-09 17:46:59 BST)

SUBARU IMPREZA TURBO 6K ECU WRX STI UPGRADE RACE RALLY on eBay (end time 22-Aug-09 13:03:26 BST)

Like I say, I'm a bit rusty so double check before you buy anything..

For starters the Z4 is 260ps not 260bhp, it will be nowhere near 280bhp. Also there is no way one of these sorts of ****e will make a car run worse unless the car has problems to begin with.

Oh the for sale section is on a different page..
