3.3TT P061B code jb4 map 1 - limp mode

[Scorpion132]

sounds good thanks Terry. I am also going to test if it is a bluetooth/app issue by setting the map, making sure its set to 2, and then closing the app disconnecting BT completely to see if it decides to change on its own again. THat should tell us if its on hte jb4 side or BT/app side.

Exact

We're one step ahead of you and determined it is a BT issue specifically related to the new batch of BT with the black shell and black wires. We're still working out what is causing the issue.

I just posted alpha v16 firmware for you guys to test with a patch I hope will resolve this.

And this is why i bought a JB4. For the excellent support. I have downloaded the firmware and will test this on my drive home later today. Will keep you posted. Again thank you for your speedy reply.

 

[Scorpion132]

Yes excellent support !!!

I will try the v16 soon

Thank you Terry

 

[Terry@BMS]

We do what we can but would rather never have random issues like this crop up in the first place.

 

[Scorpion132]

I recorded a log with v16. about 15 minutes.
I saw a false boost peak

 

[Scorpion132]

And afr signal have big drop and some big peak. Check 20200424_1720....

Some garbage logging data coming in is one issue. I'm more concerned with fault code and map switching at the moment.

Ok. But some garbage logging data is only with specifically related to the new batch of BT with the black shell and black wires ?? Or all version

New version, we're still sorting out why. Seems to only be happening on a few cars. The changes I'm working on right now on the firmware side are to protect the JB4 against garbage bluetooth data switching maps, settings, or triggering fault codes.

Ok nice

V16 Update - 45min drive on Map 2

- No random map changes. Stayed on Map 2 even with app opened entire time
- No P061B CEL this was terrible btw extreme limp mode
- Transmission felt smoother. Before it felt like a sudden delay/hesitation sometimes(randomly) when the gas was pushed and nothing happened. Didnt feel any on this long drive
- Forgot to mention prior to this i noticed it would start and stop logging all the time on its own without user input or WOT. At first i thought it was intended or normal but after V16, It doesn't do that anymore either

Havn't done any pulls yet but normal everyday driveability felt great.

Keep up the great work Terry! Thank you again for the fast response. If these issues pop up again i'll post here.

Yes me too V14 and V15. Guess these affected some people with the exact same setup.

Out of curiosity what date did each of you order the JB4 and was it from BMS or a vendor?

A vendor. Prospect automotive at Ste-Julie, Quebec. About 3 week ago

But I received it on Tuesday the 21st from PROspec Automotive.

 

[Scorpion132]

I drove for 2 hours without problem.

Check log. Some WOT. Map1 91 octane. Can you check for knock in same time ?
