It is an option in the e67 to use a 2 bar sensor because cars like the supercharged caddy cts v use it to control the s c.
2 bar map sensor max boost.
I totally agree that on a higher boost application a 2 or 3 bar sd os is required.
Is the stock map sensor on the srt 4 a standard 2 bar sensor or is it unique.
They can measure up to 2x the apmospheric pressure 29 4psi so that means it can measure up to 14 7psi boost the atmosphere is 14 7psi 14 7psi from the turbo supercharger.
2 bar map sensors are used on forced induction vehicles turbo supercharged.
This enhancement contains the following features.

It is alot easier to tune the maf than even a 1 bar never mind a 2 or 3 bar sd ve table and i have done many sd tunes.
Any help on this would be awesome i searched and got nothing.
The ecm will know its in boost once it sees airflow values over 14 7psi aka 1bar no way a regular na motor can push more than barometric pressure it would defy physics.
A maf tune will work fine on a low boost application 4 6 psi if your maf is not maxed out.

I am turboing a cavalier and i need a map sensor that can read boost for my e manage.
2 5 bar max map sensor support calibration capability for gm 0 5v linear map sensors new boost ve table from 105 kpa to 255 kpa 2 5 bar or 22 5 psi boost retains stock ve table resolution in non boost regions.
