Is there any way to log MAP values more than 255 kpa ?

Is there any way to log MAP values more than 255 kpa in LS1B ?
Car has COS 5 and ZR1 map sensor and making 25 psi of boost so thats exceed tha MAP highest value in the scaner

Wesam, because you are using an EFILive custom OS I think you can select 'GM.MAPBOOST_DMA', this should show you the actual boost figure.
I apologise if I am giving you wrong information because it was a long time ago but that should show you MAP - BARO = GM.MAPBOOST_DMA, so you will end up with actual boost figures between 0 and 255 (which at sea level would be the equivalent MAP value of 100 - 355kPa).

Thanks I will give it a try

I'm on COS3 and GM.MAPBOOST_DMA just gave me zeros, for what it's worth.
