When data logging the MAF and TPS sensor voltages are reported as "A/D Counts" and not voltage. The readings (at idle of 750 rpm) are approx. 168-169 for MAF Counts and 196-197 for TPS Counts. I am using a MAFia interface set to "2" correction between ECU and MAF sensor.

This appears to be the sample rate, or sampling sum the processor reads from the A/D in a given time interval, however I am looking for voltage on both counts. It appears the conversion is approximately divide by 205 or 206 to arrive at the actual voltage, but this is just a rough estimation on my part.

Can you provide me with the correct conversion factor?

Thanks!

Either one of yours is close enough. The one I have always used is 204.8 or divide the counts by 1024 and multiply by 5.

Thanks Chris, guess I was pretty close!
