On 2020 c63 sedan jb4 installed with Bluetooth connect. When I turn the car on it gives me this message and the gauges in the jb4 app don’t do anything:
mercedes me connect services limited see operators manual
Burgers troubleshoot said check the obd connection I did and it’s still showing up so I just unplugged from the obd from now I don’t see a point of keeping it plugged in anyways tune still works. Any ideas on how to fix it?

I like it I’m only running map 2 so not a big difference but now I’m pushing 500 hp is my guess I noticed a difference in throttle and speed the car is more tail happy now and i don’t know if it’s just me but I think it made a difference in exhaust sound too a little bit louder

Yeah I recommend it. If that’s the case you can just use it in stage 2 and get performance gain. It is a plug in tune so it doesn’t flash the ecu if you remove the equipment no one will know it was tuned and it will be back to stock. I recommend investing in the Bluetooth kit and mobile phone application to make life much easier. I’m probably going to try mixing e85 fuel to run a higher map and see If it’s worth it
Im down to get the bluetooth kit, but do I need it if Im not changing and playing with **** too much? How much would I gain with stage 1 or 2 if I left everything else stock?
So you are gonna add the extra tank for the E85?
Thanks by the way!

I may be wrong but I believe if you don’t buy the Bluetooth kit and plug it in on its own it will default be map 2 I would research more into that though. The jb4 runs on maps not stages I was mistaken with that too. From what I’ve read to run the e85 on these cars you use 70% 91 fuel and 30% e85 mix in the same tank
OK thanks,
Any idea on the HP gain with Map1 or 2 and everything else stock?
