AEM wideband sensor for EEC-IV
Posted: 2021 Aug 09, 15:34
I finally picked up a wideband AEM sensor.
The instructions state that position 4 (P4) can output emulated narrow band.
I know it's not ideal, and for daily driver any one done this.
Will or does this work OK for EEC-IV stock PCM?
And, on another note, I know people tie into the EGR sensor input for AEM sensor.
My bin has the following A/D channels:
As you can see, there are 11 channels. I believe 13 can be supported.
With some clever codding, would I be able to add channel 4 or 6 to the code, and then wire up the AEM sensor to the appropriate analog input?
Any one tried that?
I am aware that a lot of code would have to be moved as there is no free space before or after the above code, and where an assembler would be nice to have.
