I purchased a zeitronix zt-2 kit last spring in a group buy that came with the optional MAP boost sensor (3.5 Bar). I was wondering if I could used the signal from this sensor to replace the signal on my OEM 1 bar sensor instead of replacing it with another 3 bar sensor.

 

Can you provide a link to the product or MAP sensor you have?

Pressure transducers are pretty generic, I am inclined to say that you can use it as a MAP sensor.

 

thanks jd. here is what it looks like:


here is the link, scroll down a bit and it is there, Zeitronix MAP, Boost Sensor, 50 PSI (3.5 Bar) absolute pressure

Eh.

Well, it's not a MAP sensor, per se, more of an industrial pressure sensor. A lot of those are "the same thing" as MAP sensors, though.

Are there any numbers on the sensor? Zeitronix is buying that unit in bulk and reselling it... if it is a 0-5 volt sensor (or close enough) with three pins in the connector (power, ground, sensor out) then there is no reason you can't use it. Problem is, a large number of those sensors return a resistance, or have some wierd voltage range. Since it is used in a common microcontroller application, I am almost 100% positive it is a 0-5v device, or 0.5-4.5 volt range output, or something along those lines.

I'd ask Zeitronix about it, see if they'll tell you make + model, or (if they want to keep people from cutting them out as a middleman) at least some tech info or part of the device's datasheet. Failling that, we can probably hunt it down by part number, but no guarantees if it comes to that.

edit: If you know the pinout for the sensor, we can deduce it's calibration empirically... powering and grounding it, we can log 1) Vout at atmospheric pressure, 2) hook a vacuum pump to it and see where it's lowest reading occurs, and 3) apply some pressure to it to see where it maxxes out. It should be a linear output, meaning it rises X volts for Y increase in pressure, which means if you plot it at any two points you can plot the graph of it's output, just like math class back in grade school with all that y=mx+b ****.

I sifted through Digikey's listing of pressure sensors, found some sweet 3-6 bar sensors in the $18-35 range. If you get tired of fiddling around, buy a Motorola 2.5 bar or if you need to boost more pester me and I'll eventually spit out some part numbers.

 

Boost Sensor
Boost sensor is a 3.5 Bar Kavlico Zeitronix PN 80-2500-001. This sensor was chosen for
its precision and repeatability. The Kavlico sensor is more accurate than most boost
gauges.

As per their user manual.

You're awesome.

I know.

If you like to look at it in the pretty AEM pdf here is the info. http://forum.aempower.com/bbs/files/30-2112.pdf

 

great info guys, thanks. i'm really really stupid, so i'm not exactly sure on the clear answer here, but i'll assume yes, i can use it to replace my oem map sensor.

thanks again.

 

i have that sensor from zeitronix and im using it as my main map sensor. it reads vacuum and boost no problems. its the exact same 3.5bar sensor that AEM sells.

 

0.5-4.5 sensor range, too.

 

wicked. thanks so much guys.
