I'm excited to announce that thejdm is now updated to the latest phpbb 3.2 software. You may notice the site is now mobile friendly but with the upgrade comes some hiccups. theGarage, theGallery, theArcade are no longer supported. In due time the developers should be working to release the modifications to work on the new software. #LetsMakeForumsGreatAgain

Coolest teaser ever...(pumpkin update on pg.4)

general car and site related talk and chat.

neither did i really until one on a car that was built at our garage went. then i did a search on the EMS message board and found a few other people have had it happen too. but then again everything goes bad. no such thing as a bulletproof item.

first bar is used for vacum measuring i thought, thats why 3 bar = 29.4 psi since the first isnt read, or something like that.....

or atmospheric calibrations.... not sure though, i have only used the aem sensor and a couple ems i installed a while back. GM boost solenoid rocks though!

1 bar is measured above atmospheric pressure.

Boost is pressure minus absolute pressure.

10 lbs boost pressure = 24.7 lbs absolute (assuming 14.7 atmospheric)

3 bar = 14.7 x 4 = 58.8 absolute = 44.1 boost

righteous, i had always thought/ been told that the 3 bar had to use the first bar in order to calibrate the atmospheric pressue ie. 3 bar= 2 bar of boost reading + 1 bar/atmospheric

^^^ I think your right. Since the engine is normally getting air from the atmosphere at 1 bar, 14.7, if any extra is going to be added the computer needs to know to make the proper adjustments , without the 3 bar sensor the computer will still only be giving the engine enough for 1 bar.

blah, its hard for me to explain especially online. But in terms of 'turbo', lets say, a 2 bar map sensor would only be good for 1 bar of extra boost .....i think...
