hi guys,
ive just installed a z4 ecu in my 93 import 240hp.used a u8 as norm..
i have a huge s/s exhaust and hks induction.
also a decat. more boost ok. car seems to be running a lot
quieter than before. very loud exhaust fitted.not so loud now is this the norm?
or is this to do with the turbo getting more exhaust gases from the waste gate when running?
also still having hesition when driving along??
someone please send pics of were coilpacks are.. or could this be something else??... or could it be fuel rating?
u8 is available.. pm ...

 

when i fitted same ecu to my 93
its ran a little jerky @ first i did a ecu reset tho

after about half a tank was spot on
