JB1 for 1.8T and 2.0T Gen3 VAG Group

This thread is for VW JB1 Firmware Updates and Map Notes

The same BMS DATA to USB cable is used for all of our tunes and strongly suggested for free software updates and new features as we post them. The JB1 tune uses the JB4 interface. Instructions can be found here: https://www.jb4tech.com/forum/model-...ion-directions



Map List:

Map 0: Stock bypass. Stage1 fully disabled
Map 1: 4.8psi over stock, adjustable by changing "boost safety" setting on user adjustment tab.
Map 3: Progressive methanol mapping
Map 6: Custom tuning map entered on user adjustment tab.

Firmware: v4

1) Changed processor speed from 8mhz to 64mhz and increased the sampling rate of the analog I/O 4x. This seemed to have improved the idle stability in some models.

Any possibility this could be available for the Tiguan ?

Thanks

Relative to which motor. We are planning to develop more units relative to the demand we get.

If I am not mistaking, all 2009-2015 Tiguans in North America use the Gen 2 EA888

I own a 2013.

Will look into it, its the 200hp version.

This would be a big plus for ppl in my situation that still have a lot of warranty left VS a flash tune

This is awesome that the firmware have its place now!! :D

Question though, what made you run the IC at 8mhz instead of 64 from the get go? Power is not an issue - I always push for the max rating of the chip, though 64 is probably not the max the chip can handle. I should open up the box to see what part it is :p i guess timing was easier on a slower clock? I really wish to mess around with the code. Could I sign an Nda? :p

[Terry @ BMS]

I always run them as at the minimum speed to meet the sampling rates required. In this case we raised analog sampling from 200hz to 800hz which justified speeding up the processor.

[Universal_Remonster]

Is this firmware newer than the stage1_64_2.hex file?

[Terry @ BMS]

Probably same.

[George @ BMS]

Load the firmware rather then we know everyone is on the same page.

[golf7r]

I assume this firmware can be applied to either the R or GTI boxes?

[George @ BMS]

I assume this firmware can be applied to either the R or GTI boxes?

Yes it is for both.

[Universal_Remonster]

Probably same.

Sure doesn't feel the same. Can you check to make sure they're 100% identical?

[Terry @ BMS]

None of the firmware will have any tuning differences. It's all back end stuff. If you need tuning help you'd email logs to George.

But what we always tell customers who claim an previous firmware ran better for them is, run whatever you want.

[George @ BMS]

I have run them both back to back and identical boost profile on both. What difference do you see or feel?

[Universal_Remonster]

Not taking about boost profiles. The other firmware has a much smoother idle for me. Not sure why. That's why I asked about the differences between the two.

[Terry @ BMS]

If you log it we can verify what speed the processor is running at from the CSV file.

[Universal_Remonster]

I've attached the hex file that yields the smoothest idle for me.

[Terry @ BMS]

It's the same as the firmware in the first post. 64mhz.

[Universal_Remonster]

It's the same as the firmware in the first post. 64mhz.

Yes, I knew that the sampling was the same given the file name. Wondering if there are any differences that could explain the smoother idle. I'm only able to use Map 1 with the firmware because Map 6 is disabled but it's worth it for the smoothness.

[Terry @ BMS]

The files are identical, so must be a red herring.

[Universal_Remonster]

The files are identical, so must be a red herring.

That's odd because Map 6 doesn't work in the file that I uploaded but works fine in the one posted here.

From George: "There is logging capability on it but we haven't opened map 6 yet on it."

Map 6 may work but its untested on the hex file you got. Let hear from Terry.

[Universal_Remonster]

Map 6 may work but its untested on the hex file you got. Let hear from Terry.

I didn't even try it on my file. I just ran Map 1 and was running Map 6 on the new file posted here. Can't imagine there would be any idle differences between the maps on a given firmware.

[Terry @ BMS]

Map 6 may work but its untested on the hex file you got. Let hear from Terry.

As I said the file comparison tool shows they are the same file. So if map6 did not work, then would not work on the version we posted. Maybe you emailed him the file before we had verified map6 was working properly and thus the warning.

Thanks for the info. I'll try using Map 6 on my current firmware and see if I notice any difference as I've only run Map 1 thus far. I'll also correspond with George over email and post my final conclusions here so that I don't keep making this thread grow.

JB1 GRoup diferences

I just go a JB1 but I'm concern to install it on my Audi TT. I requested group II, however nothing came together saying that JB1 is specific for group II cars.
How do I know if this is the correct group model for my car?

The Group 1, 2 and 3 are the identical unit kept separate for statistics so what you have will work on the TT.

George,
I sent you an email regarding some issues on my FL S3, wondering if you have received it or not?

Hi, can you please send it again. [email protected] . I cannot recall the email.

Just sent it again George, thanks

What firmware should be uploaded to the JB4 ? I have the upgraded LHD rev1.

[Terry @ BMS]

Good question, I don't know if we've setup a JB4 thread here with firmware. If we haven't we should! George?

At this point there isn't a need to upload newer firmware. We nearly done working on some changes that improve part throttle smoothness and will be putting it up in the next week or so.

hi bro
volkswagen passat cc B8 2.0 (220hp)
which group i need to install ? group 1 or group 2 ?

The Group 2 unit is the one that should work if the car is fitted with the black engine cover. If it is still the grey top engine we do not have a unit that supports it. To be certain you can email me [email protected] a picture of the engine.

logging

Anyone know the correct way to log? i feel like im missing something simple. I started a log then drove the recommended way but no graph came up only some excel sheet which ill attach.

It will only log above a certain amount of load so that might be at play.

wellllll... ****, i put her through what felt like a good test. Drove as if i was on a track again. lol the car felt amazing! just wish i had the log to adjust it for a little more. that just gives me another excuse to do it again

Hey George, is the Group1 JB1 for the MK7/7.5R compatible with the new MK8 R?

[George @ BMS]

Hey George, is the Group1 JB1 for the MK7/7.5R compatible with the new MK8 R?

Hi,

It will not work. For this model we will only have a JB4.

[iain_b78]

Ok, thanks!

When I click in the interface download link, it says url invalid. Any idea when that will get resolved?
