JB4 install help please!

schap12 · 03-30-2014, 11:01 AM

i just received the n55 jb4 stage 2 and i am very confused with how to install on my m235i, do I follow the n55 F30 instuctions? only attacting MAF and TMAP? leaving the other 2 alone? also do I attach the can wires that come off the top of the harness? please let me know i am very anxious to install and cant seem to find and information on install other than F30.

Thanks in advance

M235i is like 435i which has electric solenoid I'm not sure how do you work on this one, you won't be able to get much of stage 2 more than stage 1 as long as you don't have Electric solenoid fix.

Ok so I would just connect the two connections then? Making it a stage one?

No you can't just connect the stage 1 wires with the stage 2 JB4, it has to be fully installed for it to work.
