Flex fuel kit
 

Hello eveyone,
Im working on making a bolt on flex fuel kit the will fit directly on the 370z/350z/q60/g37/g35. I wanted to ask if you guys where intrested in having a sytem like this made? Here are some of the details , the system will be plug and play without having to modify any harness in order to use this system, the vehicle will need to be flashed with ecutek to modify the signal from the maf and convert it to the flex fuel unit. I'm aware these kits are offered for the Gt-R guys but there are some diffrences that we would make unique to the z or g.If you guys would like to see a product like this please respond to this post or if you have any other feedback.
Thank you.

Yes.

Yes

Yes

Yep

If this was about the ability to use E85, count me in!

wish fl had more ecu tek tuners

Yes!!

I'd be down but don't want to be the guinea pig. I've don't that enough being the first G with a BP kit.

If I am reading correctly, the product you want to assemble is basically a PnP wiring harness with sensor kit?

If so, I might suggest to possibly consider 2 optional lengths for the harness. We have had customers putting their flex fuel sensors in the back above the fuel pump module (in the return line for return conversion cars). Since the VHR engine bays are so cluttered and lacking in real estate, putting them in the back has provided a location that doesnt contribute to additional complexity in the engine bay.

Sorry for the late response guys, I will be updating pictures of the unit shortly. As for the car being used as the guinea pig we already have a 2009 Nissan 370Z and CJ that's a great idea mounting the unit in the rear of the car by the fuel pump but I would like to have a unit that a "Diy" can do from his home, we have in mind mounting the unit underneath the vehicle where the return line runs. This area already has a panel to protect it and it's high enough to not have any issue also these units will be weatherproof so customer will not have any issue with water or debris damaging these units.

Interested for sure

Update pics of installed sensor I will also upload pics of harness soon, please remember this is the first unit made there will be variations made to perfect this unit. If you have feed back please feel free to reply.Thanks

The issue I see with this location is that all the return fuel kits use PTFE return lines, so it will not be as easy for people to cut the line in the middle and add hose ends.

we can extend or shorten the harness to mount the unit elsewhere so you can choose locations like the top of the tank or the engine compartment.

So the plan is to Hijack the MAF signal to run the FlexFuel sensor?

Yes, that is the plan with the Ecutek software, I'm knocking off both maf sensor using one to signal the flex fuel and the secondary to signal the Aem wide band.

yes extremely interested

Bump ?

I cut my no problem, I did this my self to put my E85 innovate gauge.

More info

I'm actually in the works with Fuel-It for making a flex fuel setup. My kit is currently installed and still in the middle of testing. Attempting to make it as PNP as possible. My kit has been installed for about 2 weeks now, just been slowly tuning it.

Currently running returnless as well still!

Its insanely easy. The fuel line plugs right into the sensor. All you need to do is make a 8-12" hose that plugs from the sensor to the fuel pump.

Go away! You don't need flex fuel in chicago

bumpppppp :bowrofl:

behold

Simple solution. I like it.

That is hot.

So how does this sensor get wired in?

I have not wired one to ECUTEK yet, so I dont know!!! I just needed to come up with an inexpensive solution to handle the plumbing side of it for my customers. I will figure out how to wire it sometime soon when I go to put this in my car.

:tup:
I'm so getting one of theses when I go flex.

I've been looking at Innovate Motorsports gauges to provide the input to the ECU because they output a configurable 0-5v signal for ECU use. IIRC, FWIH, when it comes to MT Zs, there is an unused port on the ECU normally used by the AT that can be used to input the flex signal to the ECUTECH software.

Innovate Flex Gauges;

Pics don't show for me.. but that is interesting. Does it have to go through the gauge to get the proper signaling for interfacing with the spare ECU input? (Which is awesome... btw. Good info) I'd imagine we could get it properly setup to skip the gauge (I'm not big on gauges...so a flex fuel gauge would be pretty low down the list for me)

Seb had me tie my zeitronix ECA-2 into a wire that original was something on the evap system headed into the ECU. Pictures for reference.

On a side note Phunk, how much discount do I get for not getting this badass fitting setup with my original kit ;) Wasnt I one of the first people to ask for help with installing this sensor in line... lol

Also for anyone using ecutek and your tuner can use the info below, your welcome to it.

You will take pin 102 which is solid grey in color and cut it with room to spare on the ECU destined connector side for soldering. In my case the ethanol content sensor zeitronix ECA-2 used a white/light blue stripe wire for the 0 - 5v reference and this is what is soldered into the grey pin 102 to the ECU. I also had to connect ignition 12v and black chassis ground to power the ECA-2 unit with key on.

Your tuner can then go into your custom rom and use that original input that was for evap pressure as a reference for ethanol content for flex fuel from the sensor at the return above the tank.

How about now? If you still can't see them they are in my Flex Fuel forum album.

The output signal come from the gauge. Innovate has that feature on most of their gauges to use for data logging or to input into the ECU. That opens up some possibilities like with their Dual AFR gauge and bypassing the oem sensors and using the gauge's output for the AFR input into the ECU. Well at least in theory. :icon17:

BTW here's a link to the flex fuel guages:
Innovate Motorsport Flex Fuel Guages

I was looking at the FSM earlier and couldn't find the ECU input I heard of. I'm guessing the person I heard it from had a non-SRM MT and hijacked the SRM input.

Customer installed...

I dont think this input to the ecu would work because it only reads 1.8v to 4.9v. If u are running straight pump with no ethanol or even 10% e. the input to the ecu would be 0v. (thats for innovative Motorsports sensor at least). But maybe im wrong.
