Over the weekend I installed the Apexi Power FC for FC3S in my Infini. The install was mostly painless. I removed the AFM, stock boost sensor and stock air temp sensor. I used the Apexi 3 bar map sensor, FD3S air temp sensor.
At first I got some crazy idea to put the air temp under the upper intake manifold (just like on the FD’s). I totally forgot what it was like to take off a stock upper and tb. Once I got it out I raise it above my head like “the predator” pulling that guys spine out. Well after I got out I decided not to put under it, and ended up putting it in the same location the FC air temp sensor was in the TB elbow. retaped the hole and installed it.
The car started right up 1st time. Hopefully will be able to get it tuned soon. The car drives better and feels better on the butt dyno.
only thing I noticed is I still have the therowax and when I start up the car cold it goes to 2k and stay there until it reaches normal temp. after that it starts and drops right to 750rpm.
While I was doing the install I also removed the HKS EVC and found the hose that goes to the accuator was crimp so bad that I dont see how the boost controller worked.
any know where to get speed singnal at? thats the only thing I didnt connect. If I remember right its a white wire that in cpu box in the kick pannel.
here is some picks
before removing the boost sensor/ knight sports fcd / afm
mounted the apexi 3 bar map sensor on the firewall.
Apexi Power FC and Harness
The only give you double sided tape to mount the ecu. Im going to build some brackets this weekend and mount it more solid.
