JB4 E85 and drivetrain malfunction

[Amgeater2]

Ok so I finally got around and installed the JB4, after 1:30 mins I was able to install the painful and not so easy tune. Now I have a drivetrain malfunction light on... I did not happen when I was driving it happen at cold start this afternoon, now my question is How on earth I reset the check engine light without the stupid USB cable that I just find out that I pretty much need or the dam thing is worth less !!! is there a map that sets the car back to stock and clears the code/s ?

Sorry guys I did lots of research with my phone no desktop here I am not home.

I came from the Cobb platform with the hand held device and it was great to load maps and clear/read codes so far I am very disappointed with this JB4 it's NO easy at all to install all I keep thinking is when I have to go back to the dealership and having to do this all over again WHAT a PITA!!

So again please help need to reset the drivetrain malfunction and I don't have the USB cable, dam thing is 800 dollars and no usb cable incredible !!!

I miss my cobb tune. Easiest way to load maps. Plug it on the obd2 and done. Wish cobb sold a tune for the f80/82.

Sorry to not be understanding, but a couple thoughts...

1. You drive an F8x and cheaped out by not getting the $15 USB cable? Seriously? Come on.

2. Why would you buy the JB4 and expect to run E85 blends without the map switching capability?

3. How much E85 did you put in the car?

4. Map 0 is stock setting.

To delete codes in dash you set menu mode 4/1. If you want to read codes you need the BMS DATA table.

Mike thank you for the input but can you be more detail on what 4/1 means or a link to how I can get there/delete the codes. Thank you !

You see it's not about the money, but I feel like they just want to make money on every single thing they can, this is the first tune that I buy that I have to buy something else to read codes... It's that MTax that see everywhere with this car..

I did switch to the correct map

I put 4 gallons

And the stock map is erasing the codes..

The JB4 is the only S55 tune that can read and delete codes. The DATA cable is optional because many don't want to bother with firmware updates, settings, reading faults, etc. That is more advanced stuff. Its been an optional upgrade to a JB4 system for many years, all the way back to the N54.

Did you see the video on how to use the wheel controls? Change menu 4 to 1.

I clear the codes and as soon as I hit the start button the drivetrain malfunction and check engine light are back up.


What can it be ?

Also since you didn't get the usb cable you need to call whoever sold it to you and find out what firmware version it shipped with. If it's not the right one you'll have issues. All of this is on the the link darge82 posted.

What M tax? USB cable needs to be bought with any JB4 even the one for the 328

Getting that cable will make your life a lot easier, i recommend you get one.
Also double check that the Jb4 is installed correctly

I'd also put the EWG connectors back to stock if installed. Those have been known to cause a startup code on certain JB4 firmware & DME versions. They are not used for any maps other than 6, 7, or 8 anyway. You should be on map 2 with your E85 mix.

Problem solve, the car is running hard !!! We put the EWG connectors back to stock and the whole nightmare stop.

Thank you all for the input and again special thanks to Mike !!

[RSXDC5]

Did you update the JB4 firmware?? I was getting codes like you, then updated my firmware, it all stopped.

Now granted, I still inconsistently get them running map 6/7...

The EWG connectors should be kept off for most applications.
