My GM 3bar MAP sensor instal

[colorpros]

I made my own alluminum mounting bracket and screwed it to the firewall.What do you guys think?

nice. Now lets see some 20+ PSI

very nice, looks really clean. whats the maximum psi you can push with the 3 bar map? 1 bar is like 14 something right? so should you be able to push 42psi?(assuming you were built to handle it of course)

I think around 40 is right.I think stock honda will hold around 12 to 14...?

colorpros- very clean install. well done


now, as far as stock honda map sensors, this is what they "read"

OBD0 .65 KG/cm2= 9.24 PSI

OBD1-2 .75 kg/cm2 = 10.66 PSI

With the GM 3 bar, up to 29 psi can be read

3 bar= 44 psi

44- 14.6666= ~29 psi

its actually like 27.6 psi or something before it throws a code..

why did you subtract the 14.666666? if its a 3 bar map sensor, shouldnt it read 3 bars? ie 44psi? im confused, someone explain.

atmospheric pressure y0!!!!!

we are in 14.6 psi now, the map sensor reads as long as you are on earth

i shoulda known that

 

[phunky.buddha]

Atmospheric = 14.7psi, not 14.6...

So the 3 bar MAP sensor would theoretically be able to read 29.4psi of boost.

 

[posol]

the sensor does, but the voltage gets too close, and the ecu (even a hondata) reads it as being over board.

27.6 is the highest i've seen at sea level with no map codes flickering...

AEM has a 3.5 bar map availble for their unit...
