Can I run with no air temp sensor temporarily?
 

Been waiting for my FD UIM to arrive for 3 weeks and with it ( installed ) is the Haltech air temp sensor. Need to make the car drivable, have put FC inlet back on with FC throttle body and Haltech TPS, the intercooler isnt hooked up so its running with no added turbo heat, can i set the inlet temp to 35degrees or something and just run it like that for the time being?

I think the Haltech just ignore the input if there is no sensor connected.
I don't think you can hard-set a specific temp.
It just ignores any air temp compensation.

I'm no expert, but I am pretty sure you could wire in a resister combination that would mimic a particular temp.

I have a chart that shows resistance to kilo ohms, 20C is 3.3906, 38C is 1.8027, 70C is .449

With the above info this should be do able cheap.

when the temp sensor is unplugged ,the value shown in text data is at its minmum i.e. the lowest possible reading...

Yep, you can run w/o it. While it has a significant effect when going from seasonal changes in temperature, from day-to-day, it's effect is more marginal. I don't recommend loading the car out while you're getting this sorted.

On my E11v2 it actually shows the opposite. It sits about 225*C without it connected and the Haltech is aware the sensor is missing and says "ECU Diagnostic Error".

thanks guys, yep its basically to start and move the car, and for my dad to take it for a few laps around the block once while in in canada ( for the next 6 months )

On the E8/E11 there is an option to disable the the air temp correction, in the main setup screen.

The other option is to zero out the map completely to get no correction from it. The ECU might say theres an error from an opened sensor circuit, but it shouldnt matter since its all zero'd out.
