JB4 2 Step not working
Hey everyone just wanted to see if i could get some help my JB4 2 Step isnt working properly. if I have the 2step set it will limit the rpms at full throttle whether the clutch is pushed in or not.
So for now I have it set to 0 so I am able to get on it Wiring was triple check and looks like everything is where its supposed to be... any help would be appreciated... here are some pics. |

you could also try updating to newest firmware and interface see if either of those work.

I had the same problem.
Menu 8 - set your RPM for rev limiter, future use E to 0 I was being a puss with the throttle, you really gotta slam it in and hold it, car at a stop, clutch in, 1st gear for 2 step to work. I'm still working on getting the NLS down. |

so was yours limiting your RPMS no matter what even if you had the clutch pushed in or not? thats what mine is doing. I'll try to set the future Use e to 0 on my lunch see if that corrects it. waiting on a response from jon so hopefully i can get this fixed.... side note: car def pulls hard and also had the CDV deleted feels so much better to drive. |

just tried changing future e(now meth enable?) to 0 didnt work
also tried to restore default and also already have the latest firmware and interface BMS is sending me a new clutchwire they say it might be that which i'm not sure i believe that as the value was changing when i was pushing in the clutch any other ideas? |

hey I took mine out yesterday and mine actually works.
I was just testing it in the street at idle not moving when it wasnt working. BUT when I was pushing the car and it was moving it let me rev past the point and didn't limit it. Were you testing it at idle like I was or were you actually on the road pushing it. |

the problem i was having was when i didnt have the clutch pushed down and floored the car while sitting in my driveway the 2step would still limit my RPMs to the setting i chose. but I found out when I was driving my car and floored it the 2step did NOT limit it to my RPM setting which i thought was going to happen based on testing it in my driveway
so it was working all along just that I should have road tested it instead of just trying it in my driveway |

This is so frustrating, I installed 2 step literally 2 days ago worked flawlessly 10/10 times. Then I go and update the firmware on my jb4, all of a sudden 2 step do not activate. Did anyone figure it out ?

Mine is working. It was at a stand still wether I had the clutch in or not and I floored it still in neutral it would limit but if I the car was moving it wouldn't limit it unless the clutch was pushed in
What is yours doing? |

im having issues with my 2 step as well... the 2 step part works fine for me, but the no lift shift part does not... but after looking at your photos you have brown wires installed that i did not install... Im pretty sure the DIY i looked at to install my 2step never included the brown wires. which is now all making sense becuase i remember having brown wires left over. unfortunately those wires are gone now. ill have to look when i get home i guess
