NCS Expert capable person needed in Canberra area

I run my E82 135i at about 10 race meetings per year and I need help from someone with NCS IT skills to turn off a number of "nanny" functions that continue to operate in the background and cut power even after DTC and ASC are turned off. The car starts like a rocket from a standing start using only about 1200 rpm but acceleration is noticably cut when exiting corners after the
ECU detects hard braking and cornering. Not surprisingly the car accelerates much harder on the road than the track as on-road applications of power can only be sustained for very short periods within speed limits and the additional assistance functions such as Brake Preservation Mode are not activated.
Any Canberra members who could suggest a local person that may be able to help with have my gratitude for saving me a 600km round trip to get the job done in Sydney.

When was your last dealer software update done? N54 or N55 and what transmission?

Thanks for your interest. My car is an N54 manual transmission E82 that came off the production line on 26 March 2008. It has a Cobb Access 3 reflash (Stg1+FMIC LT Aggressive IJCOS 402).

I have just plugged my C110+BMW Scanner in and it gave the following info:
Software: BMW, Software version: v5.0, SW date: 2017-06-14

I am surprised at the SW date as I have owned the car since late 2015 and it has not been worked on by a BMW dealer. Only last week I asked my local non-dealer BMW tech that has done some work on the car if he had done any updates and he advised that they have not been able to do so for several years as their workshop diagnostic machine supplier ceased providing the capability.

The best way to illustrate the hesitation out of corners is to watch the following Youtube video (
). The same situation on the road has the car leaping forward! I am not just being cautious; in my previous car ( a mildly-modded NC MX5) I won my class and came second overall in the 2014 point score for this race series.

This should be a pretty straightforward job for anyone to do. But if your car has a recent BMW software update, it is rumoured that the DSC programming has been modified in the later versions so the results from coding can vary - hence why I asked.

http://www.1addicts.com/forums/showthread.php?t=1216642 This is worth a read as that is all about your issue.

You could even buy the cable and follow some guides to set your computer up to do it yourself in a few hours if nobody is local to you.

The alternative is a remote coding service but that requires your computer to be set up aa above and you to have the cable.

I usually do my Canberra trip around winter if you can wait that long?

Hi, Did you ever find a resolution to this? I have a 128i race car that I had to do a 6 speed conversion on, and have the same problem. I've assumed it's a problem with the FA/VO thinking the car is still an automatic. I'm also looking for coding support in Southern California.

Does this problem also affect N/A BMW's? Recently purchased a 130i race car so I'm new to BMW stuff . I am also in Canberra.
