Ok guys. I want to give you an update on my latest findings. This is definitely good news from where im sitting. I recently learned how to calibrate the steering angle sensor with ISTA d. After doing so, I noticed my cars braking actions wasn't as severe when cornering. It allowed to drive with more speed around corners. The system still applied braking force at some point but the drive felt overall better.
Now the really good news. I was in the dsc module going through each coding option and trying many different values to see what would help reduce power cuts during everyday normal driving and abnormal driving. Lol! Keep in mind, I've done this many times already in the past. I decided to give Dynamic Braking Control(DBC) another try. To my surprise, all of the continuous braking action I normally feel part throttle and full throttle appears to be gone! This is with dsc on, dtc on and dsc off. Car feels normal. Drives smooth and accelerates faster. The axle is released to put the power down now like it should without the wiggley laggy feeling!
My dsc module is MK60 97 COA. Parameters may appear slightly different in your module.
You want to look for is something like DBC min ausloesedruck which means bring on/operation force, strain or pressure. From factory mine is set as wert 01 value E4. The value is what's important not the wert. The data range is from 00-ff. I set my min DBC to a value of 00 which turns the feature all the way down. FF applies more pressure on the axle.
This doesn't eliminate all dsc nannies but It sure feels good accelerating without being held back by braking. Some safeties are needed on this car even with dsc off. I read in ISTA the steering angle should be calibrated after making changes to dsc. So this must have helped. See explanation of DBC.
Dynamic Brake Control (DBC).
When, in an emergency, you apply the brake pedal quickly and with force but without really further increasing brake pressure, Dynamic Brake Control (DBC) instantly builds up maximum brake pressure, bringing your BMW more quickly to a halt.
Even when the driver fails to press on the brake pedal with adequate force, DBC ensures the braking distance will be a short as possible. The DBC control unit adjusts braking pressure to suit the current speed of the vehicle and the brake's level of wear. Furthermore, the DBC computer is networked with the vehicle's other chassis control systems, such as Dynamic Stability Control (DSC) and the anti-lock brake system (ABS), which work together to ensure the highest levels of driving safety.
Dynamic Brake Control (DBC) supports the driver actively and reliably when braking in an emergency. By electronically monitoring the speed and pressure with which the driver applies the brake pedal, it is able to recognise an emergency braking situation - and instantly ensures that full braking power is applied to the wheels. This automatically puts the brake force into the ABS range of control.
This process ensures that the stopping distance is not lengthened unnecessarily by abrupt braking. Whether the driver applies the brakes quickly or slowly, the system responds to the driver’s actions automatically and ends brake pressure buildup via DBC.
The truth is DBC is active 100% of the time and that's why it responds to pedal input so fast.
Some give this a shot and let me know if it helps.
