Hi all.

I've just bought a Techedge 3B1 wideband and have downloaded the TEWBLOG software for it. It seems simple enough except I want to log intake air temps and water temps primarily for correction map fine tuning and cold start map tuning. Anyhow, the only option for sensor calibration is entry of the temperature variable and its corresponding voltage. Voltage is the only available option for the electrical variable.

Does anyone know where I might obtain these values from? The Haltech manual only gives Temp and Resistance values for the water temp and air temp sensors.....both of which are identical.

If someone else has managed to track these values down it would be great to get a copy.

Thanks

Chris.

 

its easy to calculate since you know the input voltage of 5v, but there is an easier way

open halwin 1.71 (earlier is probably the same) go to the sensor calibration pane under setup>sensor setup>calibrate sensors. Select a default haltech sensor, and boom there it is displayed many temps with a coresponding voltage

edit: I'm bored, I'll do it for ya

 

You da man!

Thanks heaps. That makes it too easy.

Cheers

Chris

 

Google is your friend....

 

I googled that topic to death using every search string and strategy I could think of. That's why I resorted to the forum. And I searched here too! Glad I posted here when I did! Asking specific questions here is way better than googling a topic....especially when you get 189373365464546554 returns and none list the information you're seeking. I always search first though.

Well i didnt mean it that way, but i've had a tough time tracking down those numbers too, so i feel ya.

I've actually taken the info i've got and converted it to excel for better accuracy. But im sure you'll be ok with those Haltech numebers. Here's another tip, AEM.

Never use the calibrations that AEM have. Most of their calibrations for coolant and air temps were copied from the factory manuals and were never varified for accuracy. It's a well known fact that most of their calibrations are off especially for Honda and Nissan applications. Their air temp cals. seems to be the worse.

 

fairly easy to verify the calibrations, boiling water is 212f....

 

Well, call me a monkey's uncle... You'd think that they would do their homework. Although, i think that the GM sensors we use with haltech are pretty close, since they are the most popular sensors in the EMS market. The other oem ones i would understand that it would be a little more difficult to get.

But, cool, let hope haltech did do their homework? :P
