So I got a new resistor today and put it in r4. My IAT temp came back to reading correctly and now hy coolant is alot better. I still think it is about 10degrees low but I am happy with where it is at now. So after all this if you want to use the Mazda CLT and GM IAT just remove r7.

So... pulled R7... and configured via easytherm. I'm getting a solid 77 CLT and a -6 IAT... this is with updating to 029w.
I couldn't even tune the car today with it running off those iat/clt settings :(.
For the pulling R7... we are talking standalone right?
I'm bummed... i managed to drive it outta warehouse again... partway down street and back... its too rich to drive and not tunable with bad sensor input.
I have another issue... but i'll bring it up separately.

since you aren't sharing them with any other ecu, then you'd probably want to keep both in.
pulling r7 is if you are sharing the sensor with the stock ecu, as the oem ecu has it's own bias resistor. Keeping r7 installed adds resistance and throws the reading off 20° or so.

I think the stock CLT bias resistor is somewhere all ready in the line when you tap and share. Did you use the same values for easy therm as I have podted int he first post? I am with those now and they are about dead one.

I used those values. In easy therm and the GM values for the IAT. I then created the proper files, copied them over to megatune folder. I also used easytherm to update the s19 file... of which I'm using version 029w.
Bad clt and bad IAT... IAT is bad because I've pulled R7 now.... so I'll have to fix that.
