Just looking at the wiring in the picture, this doesn't look like it answers his question.

Intrigued by what other functionality the little black box can provide! Also waiting on the iPhone app!!

Well if you notice there is a fuel pressure sensor now in the system. This is currently on our development car and more coming in the next few months.

I mean, that's great and all, but how does this relate to the ECB-1, even a little? :iono:

Simple, you will not need the ECB-1 at all. That is how it relates.

Not to revive this thread but, cant we just tap the sensor wire only and feed the gauge to its own 12v and ground so the ethanol sensor isnt affected? Im too intrested in a real gauge pod not app.

It's funny this came back up actually. I have a lot more understanding of the electronics in the 86 and was thinking about this recently, and honestly there's no need for ANY flex fuel kit if you have an ECB-1.

Essentially, the ECB-1 can be considered to be its own flex fuel kit minus hose and one wiring harness. Basically, the sensor is a standard GM sensor that outputs a mixed voltage/PWM signal that the car can't understand. The ECB-1 translates that signal into a simple 0-5Vdc signal, from 0-100%, which can be found on the brown wire coming off the gauge.

If you were to run this wire to the rear O2 jack found on the front passenger side of the engine block, and have your tuner make a custom map based on the above table, you have flex fuel.

I just found the factory delphi 3 pin male and female connectors on ebay. Im going to order them and male a small extension cable so i can have a splice free gauge setup. Ill just use the a cigarette lighter power plug and access a 12v behind the glove box for the gauges power like I used on my wideband.

Connectors: Part #15326808 and #15326813

Terminals: Part #12191819 and #15326269

Seal: 15366021

This should be useful and fill my empty gauge pod hole.

Finally found it. Kind of just have to Google flex fuel wiring. It applies to just about any car.

The MTX-D will work. It reads without any other computer the 0v 0 ethanol and 5v 100% ethanol. Might need to tap right before the 02 sensor plug for a good signal.

I'm assuming you already have a flex fuel kit. Have you checked the voltage the ECU is receiving from its signal converter box?

The reason I ask this, is that to achieve the correct stoichiometric mixture with any amount of E requires more fuel, so it's better for it to be 5V at 0% and 0V at 100% (or 85%). Better to run rich than lean if the signal processing fails.

Ya i have delicious tunings kit. Kills me that it doesnt have an option for a real gauge.

Confirmed from my tuners ecutek flex fuel video the ecu reads 0v - 5v like the gauge to pull the values of ethanol.

I do think this topic not been resolved in a timely manner is counterproductive for the development the future of the GT86.
