Air Temp Sensors
 

Does any on know what the voltage to temp ratio is for either GM or Bousch air temp sensors?

I would like to build a simple temp prob to place before and after the IC and have a small duel display to monitor temps.

Here you go. I will be using one to PWM my intercooler fan.

I was building something like this, except it was going to have 5 displays in one. Now my problem was it was made for AC not DC. I can make single temp (digital) displays probably for under 60$ (thats what im currently trying) each is single so I could offer 2 units maybe for 100$? Im still currently testing. First testing will be with the water temps.

fatman keep me informed please

Here's a device that will satisfy you guys.. and it's less than $30... and runs on 12 VDC..

I just tested the resistance of the air temperature sensor in the intake elbow of my 20B. I used the MegaSquirt standard baseline temperature of 81ºF and it was between 27k and 28k.

I don't know how accurate my thermometer is, but being right around 27k is encouraging because it matches MegaSquirt's listing for Ford sensors.

The one's Im making can vary in sensitivity. Depending on the type of wire used to make them. Also if the wire is fit for that temperature range. I still need about a week or two , to finish my project, then I'll let you guys know how it looks and go's.
