z4 ecu
 

hi can anyone advise if this is mappable?
I've currently got a 7d ecu with polar performance chip and a td05 turbo. I'm looking to run 440 injectors rather than the standard 380's

Hi mate.Keep your 7d ecu and just take out your polar performance chip and get a esl daughterboard which will go in place of the chip and then get some one to map it like Duncan (raceDynamix) or Simon (Jolly Green Monster).Cheers Pete.

cheers for your advice mate :-)
I take it the esl's dont come up second hand too much as they are the best choice

The esl do come up but not often. Make sure you get a later version as the early ones aren't live mappable. But the safest way is a brand new one as it'll only be £100 dearer compared to second hand anyway.

thanks buddy :-)
