Traction control sometimes not disabled with ISO 28 - N54Tech.com

Has anyone else running ISO 28 noticed that sometimes when you start the car, traction control is not disabled even though you have it set to be automatically disabled? I just noticed this happening since upgrading to ISO 28. Probably happens a third of the time.

I'm having this issue also. It's enabled and always has been but 50% off the time it doesn't automatically disable the DTC.

Interesting.. Maybe related to the timing 2-6 CAN change. Do both of you have that enabled?

I do.

baggett67 · 08-19-2014, 06:24 AM

I do too.

Ok, so I'm not alone here. I pointed this out to Terry when the beta was released. I thought maybe it was my car only.

Terry @ BMS · 08-19-2014, 08:20 AM

Good, looks like a trend! Made a tweak to this file. Let me know if it resolves it.

same here also seems the gauges activation at 50% gas acts funky sometimes.

I have seen it twice. Once when I cut on the car and the other time the DTC light actually went out (reverting back to all traction systems enabled) during a brisk take off in 1st gear where I had some wheelspin. I haven't tried to replicate the second scenario.

While you're looking into the traction control CAN settings, would there be any way to get full DTC disable? I know you said you didn't want to at some point, but figured I'd ask 1 last time. That is the only thing I would ever add to the JB4 functionality. Maybe make it a hidden option and rather difficult to enable? Maybe you have to send a special string to the JB4 through a terminal? Idk, but that feature would be amazing.

I'd like to add a suggestion that Terry knows has also been requested before. The SPORT button on DCT's to enable on start up. I press that damn button every time I start the car.

Sorry I'm away T and can't test the new FW.

No we won't be adding that. Sorry.

Alright, well I tried. I'll start looking into a work around.

Bullitt1841 · 08-21-2014, 09:57 PM

Wow, I thought I was the only one with this issue. Going to try the new firmware, as well...

Terry @ BMS · 08-22-2014, 07:11 PM

Any feedback??

Dmac @ BMS/DMD · 08:31 PM

I threw some abs/traction codes tonight, idk if it's related. I'll post the codes in a few minutes.

Edit:
Doesn't seem to be related. Looks like my wheel speed sensor is going out.

musc · 08-22-2014, 08:50 PM

Should get some drive time tomorrow. Had a flat and tire shop screwed up my wheel reinstalling the tire after an internal patch :/

Terry @ BMS · 08-22-2014, 10:33 PM

OK someone with the bug let me know asap as I have other changes in this firmware I want to post.

Is there some kind of trick to enabling this? I go to menu 6, option 4, then just keep hitting down on the left menu button. Can't get it to enable at all, even before upgrading to 28.3. It's JB4 on 2010 335xi.

Car starts, no DTC light.

baggett67 · 08-24-2014, 07:37 PM

Hey Terry,

Seems to be working now for me. Thanks!

The feature doesn't work with Xi models.

Any chance of this in the future?

Dmac @ BMS/DMD · 08-26-2014, 03:59 PM

Had my first run-in with this DTC not being disabled today. Terry is that 28_3 different than the one you sent me 19th?
