JamesB Posted February 9, 2015 Report Share Posted February 9, 2015 I've noticed something slightly weird going on with my Nissan R33 GTR, and want to rule out the Vipec Plugin (or find some help!). Whilst accelerating, the TPS signal sometimes drops suddenly from say 50% to zero (triggering the over-run), then immediately picks up again back to ~50% all in the space of 2 seconds, and while the pedal position stays the same. I have fitted and calibrated a brand new TPS sensor but the behaviour persists. One thing to note is that I changed the default J1 jumper position soon after first installation due to an issue with the 4WD light (turns out this might have been an earthing issue with the G-sensor), and never changed it back. Has anyone seen this before? Quote Link to comment Share on other sites More sharing options...
