Hi,
I ordered a JB+ for my 2021 M235 GC and what was delivered was the model with product number B58. Can anyone who has a JB+ in their 2021 M235i GRAN COUPE please let me know what product number is on your JB+? I can't shake the feeling they sent me the wrong one.

Thanks!

EDIT: JB responded and said it's the right part. Here's a pic of the device info and location of the plug in. I had to remove part of the intake by the grill but I'm not sure if everyone does. I didn't see any other way to get to it.

FYI I already sent an email to JB but no response yet. They do not give out their phone number for tech support.

If it only has 3 wires it's the wrong one.

It has 4 wires, I just didn't find the right input. It was out of plain sight, but the pic in the instructions shows it in plain sight so I wanted to be sure. The pic they show in their instructions isn't actually a M235i GC.

It's under the snorkel.

Yeah I found it. Thanks for the info though.

Car pulls harder for sure. Definitely worth $200 and easy to remove.

BlownLSX, do you know if it is "tackable" that there has been "chip tuning" mounted, any time in the life of the car?

Do you mean like the dealer can see it when scanning? No ISTA does not see the jb+. A jb4 will block communication if not in map zero. I have a jb+ for sale also for anyone who's interested.

Sorry guys, I’m new to all this, but what’s a JB+?? A race chip??

[alphinef44]

can you show a picture of where you plugged in your jb+ ? Please i'm not sure mine is in the correct spot

[alphinef44]

its a plug and play tuning device. just stays map 1 but you can adjust the psi level

Is there anything you need to do besides remove the two 10mm bolts? Because I did that and yeah...it's not coming off.

Woof, that took a lot of shaking, lifting, sliding, coaxing, you name it, but it came off eventually. And then you need the hands of a 3 month old brain surgeon to unplug and plug the connectors. But, got 'er done and all it took was a couple of bloody knuckles, and started her up w/no SES/CEL lights *whew*.
