[2023x3M40i]

I just got a new x3m40i with a jb4 i just installed yesterday. Relatively new here and just wondering if anyone has had any issues. I installed it yesterday and after some really hard driving i am getting a wrench light in my dash. This goes away when I restart the vehicle. I am running map2 on 93 octane and all stock otherwise, id really appreciate some insight, thanks in advance!

Ps. Car has about 1.6k miles

Did you update firmware to v22?

whats the code?

No code on the car, i drove it again tonight. No warning lights anymore. That being said I was being a little less aggressive with the car than I was yesterday. I really do want to hear from someone with a 23’ car that has a jb4 to see if this is a common occurrence or it was something specific to me?

Update v22 .
It should be b58/22//5..so update it..
That should help make the truck run smoother and better alone with updated content.

Any word on how to do that, when I browse latest firmwires in the app it only allows me to select the option for b58, no specifics on the version. Am i missing something? Thanks for the help!

Sure the easiest way is to read instructions, its easy "How to update firmware:

For firmware updates if having issues we suggest you turn off WiFi, change upload timeout to 25, and set your phone next to JB4 box under the hood.

Download firmware using the new JB4 Mobile firmware database or externally by clicking this link."
