Racechip problems
Just wondering if anybody had the same problem as me. Seems as if my Racechip doesn't work. I tracked the draggy runs 0-60 and stock I get 4.2 , sport mode 3.7 and the race mode is 4.1 (no tire spin) tried contacting Racechip they said that they updated my chip but only worked once.
Just to clarify , seems like sport mode works but race doesn't. Every once in a blue moon , race will decide to work. Any suggestions? |

No issues here. your numbers suggest an install issue or something deeper.
What are your times with it completely uninstalled? (dont just change it to map zero). adding Tom aka onfireX5

Haven't tested it off, but also maybe it's cause I'm running 91??
Going to get it reinstall by somebody else. Hopefully ben can figure it out ! It just has to stop raining in Los Angeles first! |

No matter what the piggy should not reduce your power in Map 0 so I think you yank the whole thing out and run the car stock and see. If you have power back then it was install or the box. If you dont then its the car. any other mods on the car??

Just mid pipe and axle back, i don't know maybe it's car. Maybe the bmw puts a block on leases for mods ? I dunno just a thought
But like I said I turn racechip off and run the numbers and get the exact same number if race was "on" which was 0-60 in 3.95 seconds and then sport is 3.6 . |

But even if 0-60 was nothing, the Big different in 60-120 it hauls ass in race when it works. And that's what I need. Just haven dragged it yet in those times, but feels as if I don't need to do cause there's just that much of difference

Have you checked your vacuum lines on the axle back? If it was not plugged or reinstalled correctly you could be down on power.

Yep, if the installer didnt plug the valves or reinstall them correctly you will have a slower car.

My first F10 I got the Eisenmann and we didnt plug the lines (the exhaust didnt have valves)- man that car was a slug compared to what it was pre install. We plugged it and voila!!!

If your axle back has no valves, the lines from the front are probably just floating and need to be plugged or tied off. The shop should know this.

I don't have my F90 yet, but I don't believe vacuum is used for the exhaust flaps anymore. I'm not sure what needs to be done, if anything, if you unplug the electrical connection to the flaps. Since the new system doesn't have the flaps, I don't think it would cause the car to run poorly. They've gone to electrical control of the waste gate on the turbo and there's no need for a vacuum canister anymore.

I swapped the unit to another brand new that I pull it off the shelf, the took it for a spin around the block. Came back and he said it is the same thing, still no power on map 7. So, I am clueless too. Could be that exhaust valve connector not being connected. 1 out of so many that have this issue. I am planning to swap the harness (which I doubt it will make any difference) when he swing by again.
