evening all, have a 96 uk spec loon, currently has ARC tmic, AWD downpipe, AWD de-cat and magnex system and panel filter, churns out 240bhp and 200lbft, would a z4 ecu fit and if so what gains (if any) would i see? new to scoobies so sorry if this is a daft question

 

have you had it RR at that bhp or it just a guess, if! it really is 240bhp then you will only at most a 20bhp gain with the z4

 

A Z4 ecu is a 4 plug ecu and is for a td05 turbo, not sure whats on ur uk turbo, i thought it was a td04 but I may be wrong here.

 

was rolling roaded by previous owner a month or 2 before i got it, only had it a few weeks, what about torque gains tho, 200lbft seems a bit low

 

checked the turbo yesterday and its a td05
