U need a dme tune to turn it off if primary . Nothing else can turn it off not even jb4 I am talking about cel trigerred by increase boost from racechip (something different) People who had this issue with racechip will understand (some of them are on this forum) Jb4 usually works better when u habe mods because it adjusts by reading data from the obd2 ao it doesnt overboost if u have catless second or eventuri |

I have secondary catless dp and have no issues with my Racechip. I had more issues with my JB4 (which was barely any issues at all) with my older F90 than I have had with the Racechip and this car. |

Piggybacks works differently on each car and they perform differently depending on the car and mods Nothing better then a flash tune |

I had problems with Racechip when I installed it. Long story short, I was told by the actual Racechip techs that Racechip and modified cars (I have after market downpipes) did not play well. So I'm sure that lots of people have modified cars and are using the Racechip but it did not work well with mine. I went the JB4 route and never looked back.
Perhaps you need to chat with the Racechip techs. Good luck. |

Coming in with an update, this has finally been resolved... Went into the dealer last week again after I got a code thrown for Vanos bank 2. The dealer replaced my vanos actuator and so far after a few days haven't gone limp and the car feels and accelerates much much better.

Ok I know this is a bit late but I have the same problem. I don’t think it’s a big deal since I just stop at a light and restart the car and the rpm limiter on 4k is gone. However, the problem do resemble yours, I often encounter this when I am in the park mode of the car for sometime. It doesn’t happen all the time but I started to notice it after 5k miles( maybe because I installed stage 1 on the verge of 5k miles) My m8c is 2020 and with carbahn stage 1, full FI EXHAUST ( did not remove anything resonator etc)

That being said, I told them countless times to check the VANOS but they wouldn't since the car never threw a code, until 6 months later. |

I've been getting acceleration-reduced codes on my car ever since I installed the Racechip with secondary catless pipes. However, you wouldn't know unless you run a code check cos there is no light. I am able to run my best times of 10.4@132mph with Racechip, secondary catless and Dinan inlet even with the silent code. I think this car prefers an actual tune to get me that 135/136mph trap speeds I have been looking for
