Since I haven't been able to work the bugs out of my 61mm pulley tune, I finally decided to add the Fuel Pressure sensor to fully see what's going on. Apparently, I'm either missing something or I'm not as tech-savy as I thought.


I've connected the 3-wires as follows:
ZT-2 Wire Sensor Wire
Brown Black
Yellow Red
Blue (User2) Green


The Brown and Yellow are also shared with the MAP sensor, which works fine.


I've gone through all the menus and found the Analog 2 settings, which I plugged in the values for the 150 psi sensor: pressure = 37.5 * voltage - 18.75


However, when I display the Analog 2 signal, it never changes value (Stays around -18).


Can anyone tell me what I'm doing wrong or how to set this up right? I really want to get this car tuned this year...

Thanks in Advance,

Blue wire is for User1 Input. For User2 Input you should use White/Brown wire. You are not getting any voltage and therefore using the formula 37.5 * 0 - 18.75 = -18.75 (which is what you are displaying).

 

and what can be used for the user1 input?
boost goes to orange
temp sensor + IAT (toggle switch) is on user2 input (white/brown)
Fuel pressure goes to ? ...
I would like it to go on to the user1 input which is the blue one, does this work or?

 

Connect your temp sensors to User Input 1 using these instructions: Zeitronix Installation - User1 Temperature Sensor Setup
Then use User Input 2 for Fuel Pressure.
