Figured out how to Code out Rev Matching
I inadvertently figured out how to code out rev matching in all throttle modes...
If you code for a Brake Depress to be Active and make the Clutch Depress Inactive for starting the vehicle the rev match will be disabled in all modes. I also found this odd but you will still need to press the clutch with the brake when starting the vehicle even thought its supposed to be inactive...You just don't need to press the clutch as far down as when the normal Clutch Depress code is active. FEM_BODY > TCM_STARTLOCK_BRAKE = aktiv FEM_BODY > TCM_STARTLOCK_CLUTCH = nicht_aktiv My guess is the rev matching becomes inactive because of the change made to the clutch position sensor through coding Last edited by kitesurfer; 08-14-2016 at 10:20 PM.. |

Can someone figure out how to make rev matching work in Sport plus as well?

Just curious - have you tried coding off both Brake and Clutch on start? FEM_BODY > TCM_STARTLOCK_BRAKE = nicht_aktiv FEM_BODY > TCM_STARTLOCK_CLUTCH = nicht_aktiv What is the result for starting (does clutch still need to be pressed) and rev match? Thanks |

Great find
I guess quite a few 6MT owners will be very happy about this.

for full disclosure all of the coding I have had done was completed remotely (teamviewer) by a friend...I wish I comfortable at doing it myself, I just don't want to mess up something on the car. We really stumbled across this as a side effect as I was trying to code out the clutch depress so that I could make the clutch throw even shorter than what I currently have in place with BMS clutch stop. I'm glad I could share it because I know guys were looking deactivate the rev match. Hopefully someone can report back they got the same results after coding it. |

Anyway, my question, which surely brands me as a complete noob poseur moron, is: how is this coding done? I have a plug and software purchased to code my E39, but I suspect that it's a bit out of date and won't work for the more contemporary machines. I don't need a step-by-step tutorial (not yet!) but I'm curious what kind of software and hardware is required. Thanks!

The cable you need is a BMW ENET cable, which you can get from several suppliers on eBay for around $20.

hopefully lots of guinea pigs here will do this right away so i have 6 months of historical accounts to pick through before growing the balls to try this myself in the spring. fingers and toes crossed for no unintended side-effects!!!

has anyone done this yet with the intention of keeping rev-matching disabled? i'm too much of a wuss to do any coding until i know plenty of people have done it for a significant period of time with no side effects. cautiously optimistic!!!!
