Unfortunately I can't find the link again, luckily i copied the info as it took me hours to find the first time!!

This is what I found.

Boost Targets & Fuel-Cut Limits
WRX/STi Saloon ECU's 2C, U8, W6, W9 - As above, 11.47psi held to redline. Fuel-cut 14.57psi

WRX (1995/96) ECU Z4 - 12.71psi, dropping to 11.78psi @ 6600rpm. Fuel-cut 15.65psi.

UK/Aus/Euro ECU's V7, 7D and 6D - 11.47psi, dropping to 9.47psi at 6600rpm. With Fuel-cut @ 14.87psi

UK Prodive ECU - 13.33psi (peaks to 13.64 @ 5600rpm, drops to 12.71psi @ 6600rpm). Fuel-Cut 15.65psi.

STi RA (1996) ECU 7K - 13.17psi (peaks to 13.64psi @ 5800rpm). Fuel-Cut 15.96psi.

WRX Wagon ECU V9 - 10.55psi dropping to 6.84psi (starts to drop @ 5000rpm). Fuel-Cut 13.79psi

Z4 and UK Prodrive map are near identicle, with the Prodrive Map running slightly more boost.

IMHO the Z4 ECU is the best stock WRX ECU you can get, as it has much tidier fuel and igntion maps. Comparing it to the earlier ECU's I'm suprised the earlier cars run at all.....

A Z4 ECU will also run fine in a UK and give near UK PPP performance.

Hope this helps

yeah thanks for that dude

this seems to be the one i need

UK Prodive ECU - 13.33psi (peaks to 13.64 @ 5600rpm, drops to 12.71psi @ 6600rpm). Fuel-Cut 15.65psi

as i said its a uk turbo 2000 ppp so i guess 13 psi it is

thanks

13.33psi = 0.9bar and 1bar = 14.5psi

Fuel cut will be 1.07bar

mmmmmmm i need to see what ecu my jap spec wagon has then becuse it boosts at 1 bar no problem,and slightly higher at times,might be standard one fitted but its higher than the figures quoted above...... its got a lot of sti parts fitted by previous owner in japan,rear lights,front splitter,suspension etc so might have been messed with

I wouldn't be so sure. The post in red seems to list the ECUs for <96 that has a TD05 turbo.

Yours is a 97 with a TD04 so I guess your ECU isn't amonst that lot, as in there is another ppp map for the TD04's
