i have a problem with a BMW 335d E91 Automatic Transmission.
Car is tuned with Stage 2 DPF OFF and has a xHP Transmission Flash.
When Speedometer shows 280km/h it will slow down and will take no throttle until reaching 260km/h.
Then you can accelerate again until 280km/h and it will start again.
Does anybody knwo why this happens?
yes!!! what year is that?? 2013? 2012?? the ecu in your car is reading the gps for your speed.. that car is governed to 155mph or 250kmh,,, you are also using Xhp which is a mobile app and you say its tuned but what software are you running??? I bet your tune is crap.. no offense.. dont run any of that mobile shit.. get that twin turbo hooked up with a cobb tune... dinan is good.... problems solved
