I have a good friend of mine with a laptop and every software and the newest updates, but he never flashed different firmware from different cars.


I hope you guys can help me out. Thank you very much.

Hi Chris, yes Henry can do a remote service and I believe he has done that for many people. Send him a message so you can sort it out

[F82_Bavaria]

Thank you guys, i will contact him.

Just wanted to give an alternative to all this as everyone seems to have skipped the seemingly obvious path to fixing drivability issues with their £60k+ RRP car..

Recently had my 67 plate M4 CP updated by BMW to latest stock software and it has completely changed the car in many of the ways described in the thread so far regarding GTS software
(They also replaced the carbon prop shaft and parts of the diff under warranty since they were bad/broken)

Car was awful before -
Jerking/kangarooing in 1st gear
Slamming gears in when changing up - to the point of throwing the back end out sometimes
Lazy going 1st to reverse and back again
Jerky/snatchy setting off slowly when parking
Awful setting off quickly from standstill

All of this has been sorted by the software update and prop/diff being fixed

That being said I am still tempted by GTS updates, but firstly - don't just assume problems are down to software when so many of these cars have diff and propshaft issues and years worth of software updates waiting, and don't assume you need to pay someone for special software when BMW might be able to sort it for you for free

Anyone had GTS flash done on M4 CP from a main dealer?

They can't do it. They obviously have all the files & software for every vehicle, but when a cars plugged into their system it will only allow that cars specific software to be updated.

hi all i have a june 2018 m4 CP anyone moved from CP to the GTS software at all an noticed any difference (only thing that sounds useful if not just snake oil is getting the power down smoother as tend to find mine traction control all ways nannying/twitching going up 2nd 3rd an 4th going full beans unless really really dry hot/sunny day)

[fertech]

Go for the THOR Flasher and you are able to flash CS or GTS or reflash to CP whenever you like. For me with 2017 CP DCT and a friend of mine 2016 CP 6MT it makes a big difference, better traction and more grip, less nannying, smoother gear changes with DCT, steering in Sport and Sport+ is perfect now. You are getting a more refined MDM mode, THOR will come up with an EDC update also - for me the perfect way to go.

Yes, I've got a CP car and have the full GTS software. I've found a very noticeable improvement in the steering, gearbox, throttle and traction. Well worth it and bargain for what it costs.

had the GTS flash done tonight an been for quick spin

immediately noticed in sports+ steering still heavy but felt lighter felt better connected to road, biggest difference has been much improved traction even in wet/damp conditions and not getting the gear slam that would set traction control off

early days but def made it better to drive faster

will report back with more info when spent more time with it

Look forward to what your report on your GTS flash.

My warranty runs out end of month and prob not renewing so will be modding the M3, just put off a little by the hassle of going modified insurance but I suppose it will work out cheaper than changing the car.

mine still in warranty so aware bit of risk with dealer (next service not due for another 11k miles and seen a number of other guys been to their dealer without issue post gts flash) but went for gts flash as main reason was fed up with traction control constantly kicking in and ruining the experience

so far main things i have noticed especially given the bumpy typically wet cumbrian/lake district roads (ranked in order of what i noticed the most):

massive difference in getting power down for me with traction control only coming in when car really twitching but even then far far less invasive (recognise this has been my experience in wet/rainy conditions only so far)

next is the reduced gear change slam (when on no.3 setting) is far smoother and doesn't as a result constantly unsettle car and again give traction issues/nannying

steering although still heavy in sports plus feels lighter/faster to turn when at speed which to me helped give much better road/car feedback than previously

finally noticed gear change quicker especially going into or out of reverse back to drive

hopefully helps other peeps out anyway

The drive will be extremely optimised comparable to the M4 GTS as it's OEM software ??
It feels much smoother and responsive.
All done by a fellow M4 owner ?

Here are the two cars:

What about the fact that a standard M3/M4 has no waterinjection?

Hi there,

The software doesn't take that into consideration as we are not flashing the OEM GTS 'Engine' software. We are upgrading the other components found in both standard F8x and GTS/CS.

[propete1031]

Hi will this GTS flash change engine / exhaust noise also? As in louded, more burbles, cracks and pops etc?

[Vergis]

Get the GTS Steering and Chassis flashed GTS and CS traction control. Then your ready to go. Best of all worlds.

I would advise people thinking of doing this to search previous posts in relation to the above poster & the 'service' he offers. That's all I'm going to say. Everything you need to form your own opinion is available to view within the forum.

[2018M3DC]

Hi Henry - I’m interested in the complete GTS flash package you offer however i live on the east coast USA. Can you do this remotely? I have a ENET ODB2 cable and USB ODB2 cable already. also IO’m about to get the upcoming Dinan DME Flash +HE (beta tester) which is going public in November 2019. Can you confirm if what you do is compatible with the Dinan +HE Flash to the DME which adds about 68 WHP. Thanks in advance.

Please use due diligence and do a search on Henry/Kurai before purchasing his services. As you should with any tuner/aftermarket company. It's an expensive car afterall.
