I searched but couldn't find any data on this. I'm running the stock IAT for now and its off by a country mile. Read 53 F when it was 32 F outside. I am using the GM IAT settings and obviously they dont work.

Any help is appreciated.

 

°F

1450 bias

-4 16200
68 2450
176 320

 

That's what I used but with 2490 bias. In some previous posts its been said to use 2490 ohms if the setup is standalone, which it is in my case. Do I still go ahead and use 1450?

 

Only if you have a different bias resistor. I believe the 1450 ohm is for sharing sensors with the stock ECU.

 

whoop yeah, forgot you are stand alone....should be those numbers but 2490 bias.

coolant should share same values...heck just use rx7 defaults. make sure you are copying your .inc files over to car1/mtcfg

 

Cool, thanks guys.

 

and what about the GM iat sensor from DIY and the stock '94 CLT sensor on a standalone MS from braineack?
rx7 defaults too?
does is matter that I'm using degrees celsius instead of degrees F?

 

so is the question "do i use the rx7 defaults for the GM CLT sensor even though there is the option of GM defaults?" ?


EDIT:

typo above, CLT should be IAT. should be:

is the stock miata CLT sensor a GM sensor too?
if so, excuse my retardness

 

it's pretty simple.

GM air sensor use GM defaults for the temp-resistance pairs.
Stock(which is Mazda) CLT sensor use the RX7 defaults for the temp-resistance pairs.

2490 for the bias resistance values on both unless your MS was not built to Scott's specs

 

that's all I needed, thanks
