Hi Guys, Ethergore sent the ECU back to us to look at. It looks like SlyAlfa didn't setup an ADC wiring as there was no plan to use bro correction.
We have wired up a early 2000's Denso sensor on pin 16 which is tied to ADC channel 5.
The issue we are having is ADC is far too unstable. Voltage at the sensor is verified stable ...around 3 volts. But when viewing on VEMS tune, voltage fluctuates +/- .07 volts...this causes Baro input to rapidly fluctuate between 98-104 KpA, too unstable to be useful for us.
Does anyone know why ADC is jumping around so much? Is that normal? We noticed ADC jumps around on all channels, not just the one we are testing on. We feel that we can help Ethergore with external baro as soon as ADC issue is resolved.
