  1. Infiniti Q60 Issues And Problems
    So I’ve had this problem intermittently for a while now but it’s been getting more apparent recently. The pull will start strong then come around 4.5/5k rpm it feels like I hit a brick wall and the car jerks really badly and will sometimes throw itself into limp mode with no MIL or codes...

  3. Infiniti Q60 3.0T RWD Discussions
    When I try to launch the car, I’ll spin quite a bit off the line and it’ll cut throttle and bog until I shift to 2nd gear. I’ve tried not “brake boosting” and it’s a little better, but I want to be able to brake boost off the line. Currently on 275/35 Indy 500 on the rear. I have Jb4 on map 6...
  4. Turbo And Tuning
    Hey all, this is my first post so go easy on me. So I did a couple of pulls on map 3, and to be honest, I'm struggling to understand what the "trim" and "ignition" should be. One thing that has me concerned is the AFR going super lean. Is there anyone that could give me any input on the...

  8. Turbo And Tuning
    Attached are the JB4 map 6 settings and graph log for the same run. It was a 3rd gear run from 2000rpm to 6550rpm (in 3rd) then shift to 4th and I let the car decelerate to about 3000rpm. My biggest concern is the the AFRs during no throttle in deceleration is as high as 25.5. Is this normal. I...

  11. Infiniti Q60 3.0T RWD Discussions
    Hi I was wondering is there any way to have multiple OBD connections in the Q60? Or if I should get a splitter? I am trying to connect a gauge and JB4 but I mean there's only 1 OBD port. I just head that splitters usually turn one port on and the other off and keep switching so I was wondering...
