After seeing a few installs online with this kit along with the official Delicious Tuning instructions, I realized everyone else seems to be installing it differently than how mine was. My setup kept the original flow path and put the sensor inline and that was it. The instructions I see now make it look like they flip flop the direction of flow. Not sure why

Hi,

The instructions show to swap the fuel lines in order to fit the fuel lines as we initially intended. It does not change the direction of the flow, as both fuel lines are feeding both the direct injection pump and the port injector rails. This is a dead headed system so there is no return line to the tank.

Cheers,
William

That makes sense. Usually when there are 2 lines one is supply and one is a return. It looks as if we have a returnless system with 2 supply lines. Good to know. Thanks.
 
can you install the flex fuel kit and drive the car on 91? or do you have to install them immeditely tune? I want to go ahead and install and not have my tuner do it he will charge out the ass
Yes. The whole "flex" part of it is having the car adjust to either type of fuel. Do NOT fill up with Flexfuel without a tune. I had my kit installed for almost a year before I finally got tuned, just running 93 the whole time.

On these specific kits, you can install the kit completely, leaving the harness disconnected, until you install the tune. This makes it very easy for whoever will be loading the tunes on the car to just plug it in and start tuning.

This is news to me. I ran the CAN style kit on my car for a good 7 months before tuning. It was fully installed, plugged in and relayed my ethanol content VIA bluetooth to my phone. The FF kit is just a sensor and BT module. It shouldnt have any impact on tuning, until the ECU is told (tuned) what to do with that 5v signal from the ethanol sensor. That is what I was told by Nazar when I emailed with the same question. I ran premium along with 2-3 gallons of E85 blended in as I had been doing in the hot months and the car seemed unchanged in any way.

Yes that can be done do this. But we do not recommend it unless you are knowledgeable about vehicles. The only potential issue(s) if there is an overlapping CAN address or something is not correct on the kit itself, which you (the green thumb customer) may not know how to interpret that. So it is one of those safer than sorry things, that is all.
