ok thanks for that.according to your list ive got an ecu for a wagon?? now im wondering if a previous owner has put a different ecu in.this may explain why sometimes my boost drops to about 6 psi.

it would appear so, you should have the Z5 in yours. good choice of car btw i used to have one

wagon will be running a different turbo as well.
standard power should be 260ps

chrisdrew83

what turbo is in my car? is it the td05?

iTrader: (1)

yes.
Import wagons had td04

chrisdrew83

ok thanks.so basically im not gona be running full power on that ecu? ive been on ebay and theres a Z4 ecu.is this pretty much the same?

the ecu will take into account the cams, so with the Ra potentially having more aggressive cams you might still be a bit down on power.
You could keep your present ecu and treat yourself to an ESL live mappable board.
I got mine from jollygreenmonster and it was bloody excellent, only changed it to get a powerFC and now simtek.

i think im just gona try and get a second hand Z5.

How urgent do you want a Z5??

Ive just sold my 96 RA to a mate of mine and he's just bought a GEMS ecu to replace the Z5.

The thing is it wont be fitted and mapped for a month or so.

chrisdrew83

Its not that urgent cause the cars still driveable but obviously sooner the better. Do you know what sort of price he wants for it? Ive seen Z4s on ebay for £150!! If you could let me know that would be brilliant.

Check that that v5 hasnt been chipped?, the previous owner could have sold the z5 for good money, and bought or been supplied the v5 and had it mapped and chipped, worth a check.
