Bimmerlink

I bought this app from the pictures and what I have seen that it reads pretty much all values in the dashboard, however I'm mistaken. I don't think they have taken into account we have 2 DMEs so it only reads lambda bank 1, the value confuses me there as I'm use to those readings being between 11-14.7 for the AFR but this reads between 0.9-1.02 circa.
Then we move on to boost pressure, bimmerlink has pictures of it reading boost pressure but my only option is absolute boost pressure so that's already added 14-15psi or 1 bar before we have even started.
Could anyone shed some light on this.
TIA

The lambda can be easily converter with a lambda calculator, that's what I used. As for the boost pressure reading in bar, I can't say but I agree with you that it's a little confusing. I did a data log and according to the data recorded I was boosting around 30 psi which I know is not correct.

Thanks buddy.

I found a calculator and lambda 1 is 14.7.
However it would be handy if I could change the unit value so it reads 14.7 etc
Plus is there any app out there that can read lambda 2
I think the developers forget we have 2 DMEs.
Is there any option so it can chose a real time boost value? 1.02bar at idle 😂

I know this is an old post but just to clarify for people confused about the absolute boost pressure reading 14psi or 1 bar, that’s because absolute boost pressure considers ambient air pressure which is around 14psi or 1 bar. So basically anything over that is going to be how much boost your making.
