Hi all. Quick question for the tuned E30/E50/E85 guys. What are you using to measure/display ethanol percentage on your SCT/BDX/nGauge device? Inferred PCM values or analog input from a dedicated sensor?

I built an arduino-based solution (using a GM sensor) for a Mustang which I can reuse if need be, but would prefer to use the inferred values if they are accurate.

Doesnt the nGauge have a native alcohol percentage readout?

Yes the ngauge absolutely has a % alcohol readout.

If you have a SCT device I can send you a log file that will read/display alcohol %

I have an 18 3.5 will your file work on mine to measure Ethanol Content? If so that would be AMAZING.

I'm not sure. I know it works for 2011-2017 5.0, I'll send it. Give it a try.

Thanks to all for the replies.

Looks good - how have you found the accuracy?

I have a test kit also and it's spot on. What truck do you have? Shoot me your email and I'll send you the file. Can't hurt to try.

Can you send me that also? I added an alcohol PID to my normal data log file but it doesn’t read on the actual BDX, just the data log on the laptop.

You’d be amazed the number of folks that say this requires a sensor. I think asking your tuner to “turn on the PID” is the solution with the NGauge, only required on vehicles that aren’t factory Flex Fuel.
