Are there any aftermarket HUB that can monitor 450/M256 turbo pressure on MB engine? Just bought BLUE DRIVER and its Turbo monitor is not compatible 😩😩😩

I am using the following:

1) Vgate iCar Pro BT 4.0 - https://www.aliexpress.com/item/3287...5bef1802pI9BsE
2) Car Scanner ELM OBD2 - https://apps.apple.com/us/app/car-sc...2/id1259933623

Through OBD, i can view Boost, AFR, water temp, intake temps.

This combo is pretty cheap to start with, it helps for any CEL checks as well if you get any and display the CEL codes.
But just to note that OBD readings on boost usually reads up to 1.55 bar (22.5 psi), so if you're tuned above that then i would advise fitting an aftermarket boost gauge (something i will go for after... eventually).

Hope this helps.

Wonder why the expensive Blue Driver can't read turbo pressure. Seems odd for tool that cost over $100 and has great reviews.

One thing it does read is the hybrid battery % charged. Good way to know if you are running low on the 48 Volt battery (for people who's 48 volt batteries that are dying) . It seems it stays between 80% or so to 70% most of the time. Lowest I seen is at 65% and highest I seen was like 84%
