Please help! Have a RSQ3 race coming up.... :burnrubber:

Leon@86 09-20-2020 04:56 AM

So no feedback an this bug on revision 15? Feel robbed now because I bought a feature that I cant use. NLS not functioning either. Please can anyone give feedback!

brendan 09-20-2020 06:49 PM

Yea my 2 step does not work still.

I someone could explain the new settings and firmware to get it working again that would be appreciated.

Leon@86 10-16-2020 04:07 AM

Sooooo, still no feedback as to rectifying this issue?

brendan 10-16-2020 04:08 PM

The only way to control the engine is with an aftermarket ecu.

I have had everything working then next drive out they dont.

My boost by gear wont work.
Antilag works but timing stays retarded until I change gear. Defeats the whole purpose.
afr and portinjection flow not stable or contrable enough.

Once you get to a certain level jb4 can only do so much.

Leon@86 11-23-2020 09:48 AM

Can anyone please shed some light on what is going on with the issue on the 2 step not working anymore after firmware update?

Terry @ BMS 11-23-2020 10:38 AM

No known issues so post up a JB4 log if you need assistance. If using a 2step make sure you have the latest v15 update for twin or v139 for single turbo.

Leon@86 11-24-2020 09:44 AM

There are multiple people a couple of posts back complaining about the same issue.

I dont understand what must I make a log of.... The 2-step with anti lag integration used to work, I did the update to v15 and it stopped working. One guy reverted back to v14 and it was good again, but this did not work for me.

As I stand now, no 2-step stand-alone or integrated and no NLS.

Terry @ BMS 11-24-2020 10:47 AM

What isn't happening exactly that used to be happening?

If there was a firmware problem it would effect ALL users of that firmware not just one car for example. For example firmware older than v15 requires a clutch wire we no longer offer so anyone running 2STEP relay without a clutch wire needs v15 or newer firmware or it won't work.

If 2step/NLS isn't working at all for you, perhaps your 2step relay has failed?

Leon@86 11-30-2020 05:16 AM

Ok thanks Terry.

I will check the relay, just found it strange it stopped working only when did v15 update.
But I do understand what you are saying. It is strange only few cars are effected. especially AnilKram had the issue after update, then after going back to v14 it was fixed.

Will check relay and report back.

mattgu40 12-11-2020 04:20 PM

Not sure my 2step relay is working as menu 8 is not doing anything / not activating. Changed relay doublechecked everything.
Tried it with MHD rev limiter/ launch control...
3.4k rpm 14psi
5200 rpm 26pis.
No way i am letting go of that clutch

AnilKram 01-08-2021 12:47 PM

So do we have to purchase a new 2 step relay? I never removed the clutch wire from before either.

Terry @ BMS 01-08-2021 12:56 PM

Not had any mass reports of problems. If you need specific technical help just email us.

AWDGT2 01-08-2021 02:19 PM

Any plan for this on the Stinger platform?

Bimmer_n54_e92 01-17-2021 10:35 AM

Does anyone have the G5_ISO_32_14 file. I'm trying to revert back as my 2step/antilag integration stopped working after going to G5_ISO_32_15.

Much appreciated.

You can download it on the same page as version 15.

Dont get your hopes up though, didnt work for me when I reverted back. Ive just given up because there are so many people complaining about this issue and there is no resolution.

Ive checked relay and completely redone my system to maybe see loose connection or something but it still doesn't work. Issue only started with Version 15 beta so there is definitely a bug or something.

Good luck and let us know if reverting back helped you.

work but 2step wont engage.

I reverted back from G5_ISO_32_15 in the past and it fixed my issues. But then I went to v15 again and deleted my v14 file and now I can't revert back. It seems that only the newest firmware is available. No previous firmwares are shown. If someone could send me the file for G5_ISO_32_14 I would really appreciate it.

Thanks

JB4 log running anti-lag?

Bimmer_n54_e92 01-19-2021 11:30 AM

For those who have lost the 2step/antilag integration after the v15 update I found the file which has the working integration of 2step/antilag.

Here's the link https://www.mediafire.com/file/hn7jb...32_14.hex/file
