I have a n54 with reflex plus port injection set up single turbo . With the ARM BOV line upgrade. 1) i already have an ethanol sensor just need the harness. Can i connect it to the breakout harness supplied by Motiv? 2) where do i plug in the vacuum line? Do i need it if I’m going throgh OBD port??
If the Motiv can directly process the raw 50-150Hz output signal from the ethanol sensor then yes, you could tie the sensor directly to it. If the Motiv needs a 0-5v linear signal then you could wire the ESVA in line between the Motiv and ethanol sensor. The vacuum line from the boost tap would run to our analog boost sensor which can be found here - www.p3cars.com/gauge-accessories/add-on-sensors/p3-analog-boost-sensor/ I would suggest running it for your boost reading with your build in this case.
I have a question about this. You said 12v this is for the ethanol analyzer and also for the ethanol sensor voltage adapter. Which fuse would be appropriate to use to power? A red 5, a 15 blue, a yellow 20 fuse? Not sure which one would be sufficient. Thank you for answering my question. I have this all set up aside from the power.
So all those ratings are AMP values, not voltages. Most all the fuses in your fuse box are 12v but a couple may be 5v so you'll want to check for sure that you have a 12v fuse. I would suggest using a non-essential system like your 12v power socket in the dash or your cigar lighter. That way if there's an issue you don't lose power for an important system.

I haven't had the car tuned yet but just wondering if it should be reading something for ethanol on 93 or if it wont read it because of the low ethanol content? It reads 0 right now but it does hace the esva.
Unless the fuel is advertised as “ethanol free” it will typically have 8-15% E in it. If you’re seeing “0” it sounds like there may be a wiring issue or issue with the sensor or ESVA. Please email support@p3cars.com and I’ll follow up with some remote diag to see what’s going on.
Quick question. I’ve got a P3 and my tune already pushes a content value to the ECU, which I can read with VAG COM. Can I push that percentage directly from that channel. The better question is, can I push the value of any channel to the O3 or do I need this adapter?
Hey Jedediah, currently you cannot pull that value over the CAN-bus so you'll need to use the ESVA to translate between the ethanol sensor and the P3 gauge.
So is it okay to tap into the white wire on the sensor if it is already running into the car's ecu? Just want to make sure it wont mess up the signal going into the ECU.
That is completely ok. The signal output to the ECU will not be affected by another device monitoring the signal also. So you are good to tap the white wire to get the Ethanol reading to your eyes. If you have any other questions please email support@p3cars.com, thanks! -Jake
Why can my HP Tuner ODB2 read my sensor data without this? Update: I get it. This intercepts the signal before it goes to the ECU while HP Tuner is capturing it at the ECU. Note: An ODB2 app can read the PID right from the ECU with an ODBlink MX+. and display it to your iPhone.
Thanks for the follow up. Our gauge can read now read ethanol content on our GM product right through the OBD2 port. It also can on a couple other models as well. at the beginning of 2020 we started with the ESVA using the analog inputs so that all models had the ability to read E content instead of writing software for all the different applications and then confirming each one worked. As time goes on there will be more and more models that support OBD2 E.
Yes, this works with all the common GM ethanol sensors (basically any sensor anyone is using in their kits) just as long as it has a 50-150hz output. ALSO and V3 gauge purchased directly from p3 7/1/22 or later is able to read ethanol directly through the OBD2 port without needing the ESVA
If your fuel it has the 50-150Hz output, then yes. If yours has the 0-5v output then you will not need the ESVA and can tie that output directly to the analog inputs on the p3 gauge.
@@P3Gauges tie that 1 white wire from the sensor to the 2 analog inputs for ethanol content and fuel temp? I believe the fuel-it sensor is 5v for the jb4 so I was wondering how to install it. Now I’m Confused lol
@@vwjet357 if you have a fuel it with a 5 v out just run that wire straight to the brown wire on the p3 gauge (no ESVA needed) If your fuel it has a 50-150hz output you’ll need to wire in the ESVA between the fuel it and the p3 gauge
@@P3Gauges thank you for the response! so connecting my white 5v wire for my ethanol sensor to the brown analog for the P3 will be enough to show ethanol content and fuel temp? And there’s no need to use the ESVA? Just trying to confirm lol about to go out and do it right now.
Correct, nearly every car we support doesn’t come with an ethanol sensor from the factory, they need to be added on. This device just translates the signal coming out of the ethanol sensor (factory installed or aftermarket) so our gauge can read it.

I have two P3 guages fitted in my car one anologe and a P3 V3 can I wire the one ESVA to both guages?

On the DSX Tuning Flex Fuel Kit, do I just tap the white wire from the P3 sensor to the white wire coming off the DSX sensor?
Yes, you will just tie the white wire from the ESVA into the signal output of the Flex Fuel sensor.

What is a good min Ethanol content before losing HP ?
Hey John,
That is something you would want to consult with your tuner about.
