z4 ecu install...whats going on !
 

hi all,
:)
as above.whats going on here??installed z4 ecu on my93 import:)
ive taken it out on short runs ....still running lumpy:mad: seems like engine
is holding back through the revs??? still!! put 97 ron in or could there be a
problem elsewhere or is this the norm:wonder: is ecu still learning?
or do i need to take car on a longer drive??
reset the ecu yesterday(the proper way)...check light keeps flashing on and off quickly is this normal???. :cry: please help me....whats wrong here or will
the ecu sort it out ..will it run normally again:confused:

help!

The CEL shouldn't be flashing at all have you checked for fault codes Chris Palmer's Home Page.
When i installed mine i went for an hour driving at various (legal) speed limits.

dont quote me on this but i think the z4 is mapped for a higher ron fuel than 97, try filling up with v power when you have used all your 97 ron fuel.

Or add some octane booster if the higher RON fuels aren't avaliable
