I'm using a factory S4/S5/Cosmo IAT sensor with my E11v2 but am having some trouble with the settings - everything I do the ECU comes back with a diagnostics error.

Does anyone have the sensor settings for this? I kind of guesstimated based on the Megasquirt settings I found online but obviously I was wrong!

Yeah, thats an aproximation to the possible values, since mazda only puts aproximate values in the FSM anyway, so it probably works relatively decent, worst case scenario you get the Haltech sensor and dont have to brake your head trying to figure it out.

 

You really don't need to be spot on, unless you're staring at the laptop just to get accurate intake temps?
It's only used for the correction maps, so the values are relative.
Most original, stock temp sensors drift off of posted values due to the characteristics if thermistors.

It should not be erroring out though...

If it errors out he's not set the minimum and maximum temp limits or the proper calibrtion, or the sensor is bad or disconnected.

Another reason ive seen diagnostic errors when there shouldnt be is due to applying major changes in the map files and not resetting the ECU properly.

Reloading the DEFAULT base map clears these errors, then you'd just need to reinput your settings on to this new map.

 

Thanks guys, it's definitely the IAT sensor settings as if I do a sensor diagnostic it comes back with an error. I think I hadn't set the 0 value properly so it was freaking out.

Won't be back at the car until Friday (or maybe Sunday) and will try then.

 

keep searching there is a thread with the proper calibration for the S5 sensors, what is posted by claudio is for the S6.

Cool, thanks! Not certain which sensor the stock 20B equates to, but I think it's an S5.

 

I believe I was using the 13B-re sensor, if your using an S6 sensor then you can use them on the haltech default calibration and they will be at most 15 degrees off on the hot side.

 

Cool, so I guess the 13B-RE sensor = S5?

 

probably
