I'm am having trouble with my Zeitronix ZT-2/3.5 bar MAP sensor combo. With the car off, it reads -7.0 or so and with the car on it reads a steady 25.50 no matter what I do with the throttle. Does this suggest a particular problem to anyone?

I installed this a few months ago but haven't really used it until now. I can't remember whether the boost sensor was working before or not. It does datalog AFR and RPM without a problem.

Thanks.

 

sensor itself seems to be reading off. You have a mechanical gauge or this is your only reading unit?

 

Are you using the 5v output from the Zietronix unit to power it? ALso make sure it has a good ground.

 

I have a boost gauge on my EBC, which shares the same boost source. I am using the Zeitronix +5v output. The wires out of my Kavlico boost sensor are white, black and red. I'm assuming that the white is the signal wire. Black is to brown sensor ground on the ZT2 and red is to the yellow +5v wire. White is to the ZT-2's orange wire.

 

double check your wiring zeitronix.com has a wiring pdf

 

Turned out to be either a compatibility issue with the SSI/AEM MAP sensor or the sensor went bad. I had another AEM sensor on hand and now it and the ZAVT-1 failsafe work perfectly
