Zeitronix Ethanol Sensor
Hey guys. We just bought this for the car I'm doing work on and tuning (Zeitronix ECA : SEMA Award Winning Ethanol Content Analyzer and Flex Fuel Sensor for E-85 and E-85/gasoline Blends)
Where should I tap in to the fuel lines (in series) to add this sensor/gauge combo? I know direct injection cars put out high fuel pressure so I'm not sure where exactly I should tap in. Thanks for the help!

Thanks for the responses guys! I run this on my STi and it's great to be able to see exactly what the percentage is.
I just wasn't too sure where on the LNF it needed to go, I think I know now. I will post pictures once I'm done installing it. Hopefully today.

So yes, it's basically just to monitor.

Anyone else looking to play with this can get the Conti sensor elsewhere for cheaper.
Still need a data sheet to get the pin-outs if you wanted to just try wiring it to power & analog voltage displays.

I dont want to sound like a downer or anything, and thats really kool, But here is my problem with where you put it, if your driving and you hit a bump or somthing and fuel leaking and goes towards the turbo your going to be alittle screwd IMO

Thanks, I appreciate the concern. However, this isn't coming off. This is on way too well/tight.

We do something similar with the 1.4T market. I'm not sure if HPT supports it or if the LNF ECM even supports it, but with Trifecta we are able to run a wire from the sensor to one of the unused pins on the ECM and have the ECM monitor ethanol content and adjust your tune on the fly in real time. I believe EFILive can do this also on certain ECMs. If you guys are interested I'll talk to TF and see if this is possible on this ECM and maybe we can work out a layer tune or something so you can still tune it yourselves using HPT.

On the software side of it I don't think it would be hard to do seeing that it's a linear change on the output of the sensor. However if blocks on the ECU are not available then it may be a big hurdle, especially in realtime.

Total install for the under-hood portion was 5min. Wiring took me 10ish min.
