Spare ADC for EGO input

Post by hiltonlo05 »

Embarrassingly basic question...but

I'm currently using Spare ADC for a Trans temp sender and using a 2.49k resistor in R67 slot for GM sensor reference.

Can I remove the resistor in R67 (making the circuit the same as EGO2 I think) and use Spare ADC as EGO1 input in the AFR control tables?

This will provide a quick and easy fix in the meantime while I sort out a CAN input device.

I'm getting a configuration error and the fuel pump cycles on and off when I try to assign Spare ADC as EGO1 or EGO2. Currently using the actual EGO2 input for one of my widebands. If you guys don't mind, take a look at the msq see what Ive got out of place in the settings. Its got to be something simple that I'm overlooking

Turn off the Generic Sensor 3 input; it's also trying to use Spare ADC.

Ahhh... Ok, I thought I had to set up it up as the ego calibration and then reference that in the AFR control menu. It will be a couple of days before I can get back to the car to try it.
Thanks Matt!
