Just install my VAFC
What should the pressure sensor read with ingnition on/engine off

Mine is reading 0
When i disconnect the Pressure signal wires it goes to .015
I have the Presure signal wires connect to the Blu/Blk Wire on ECU
I have a 2001 ITR
I irgnored the VTM signal wire on the VAFC

Can ANy one help???

 

it should read -760 mm/Hg under full throttle and 0 when off (maybe its the other way around... didnt feel like going out to check)

 

mine reads -40 something when the car is off, but the key in the ignition.

with the car at idle it is at -400 something...

i don't ever look at it much under wot, cause i'm usually concentrating on driving...

i'll get someone to check if you really wanna know.

and YOU SHOULD HAVE THE VTM WIRE CONNECTED! IF NOT, no VTEC FOR YOU!

 

I have a 00SI with VAFC....Under full throttle with AEM I get 0.00-0.04 depending what gear and stock intake get about 0.02. Idle is around -500 or something like that. The higher the pressure the better the car runs. Different cars are different though. Buddies Prelude with BOLT-ons through the ceiling only gets about -4 and sometimes 0.00 on WOT

 

Around -400 at idle (Spec B's) and 0.00 at full throttle.

And about the VTM wire? What Ken said
