Sure, but i'd rather do some simple math in my head to ensure I don't screw too much with fuel trims. E30 to E38 is only 8 points, but can make a difference depending on maps, boost and other factors.
But lets go the other way... 8 gallons is close to 6, so lets do that. Now you are running about a e48 which is no bueno.

I guess it's all ballpark, but i'd rather control what I can, to ensure the stock fuel system stays in check, especially with the heat we are experiencing.

The ECU is highly adaptive with it's full time closed loop fuel control so you don't need to be overly precise in the mixture.

Please and thank you!

I haven't looked at the 2L PCV system yet, have photos of the current OCC offerings out? I'll see if this look compatible.

ok, my point is simple... If you don't know the exact ethanol content of the gas (say 93 octane premium), the exact ethanol content of the E85 or at least octane, then you are just mixing on assumptions and guesses... which helps as to what Terry says... it doesn't have to be exact. I would think that if you try to be consistent in your sources of fuel and your mixtures, your logs are your only hope to maximize performance.

Thanks as always for the quick response Terry.

I don't have any OCC installed right now, but is this what you are looking for?

Happy to do more research on my own to get you the info you need, but I am not very mechanically inclined, so you might have to lead this horse right into the water :)

Fair enough... I was too cautious with my past BMW and Golf R on JB4's when running E85.

Got my JB4 installed a bit ago. Having trouble getting the firewall grommet to move for ob2. Any suggestions? This is a genesis g70 3.3t

Well that’s really not free. Maybe your time is but certainly not mine. If someone is going to take the time to pull plugs it only makes sense to drop a better plug in as opposed to the trash KIA used (even re-gapped).

There's a gap where the front fender meets the hood. Squeeze it in through there and have it come down by the door.

I know you have a G70 but this is worth a shot assuming you don’t want a wire coming up through the door jab.

Thanks for this. Doing this as a temp solution. I will get it wired better and I need to change out my plugs.

This is what I needed to see! I was trying to pry the grommet out towards me. Thanks for this!!!!

My first few pulls after install. This is on stock plugs and 93 octane.

You’ll want to run the same gap as the other plugs. .020 - .026 anywhere in between there will be fine. Whatever you choose, try to be consistent across all plugs.

Hey Terry - just wanted to check back in on this. Are the pictures in this thread what you are looking for?

Thanks for the photos. I can't quite tell what I'd need to know, we will need to track down a local 2L Stinger to poke around. If anyone local to us has one can provide a free OCC solution (once we figure out how to do it!) in exchange for your trouble. :)

Hi Terry,

Could you review these logs? They're my first hits on Map3.

On the 04_38 log, should I be concerned about the boost and throttle drop when it shifted?
It felt like a really lazy shift, never does that on Map2.

I was running 4gal of E85 mixed with 93, 103 degrees outside.


THanks!

Damn.. wish I was closer, but I think I’m on the other side of the country. Where abouts are you located Terry?

I’ll see if I can get some buzz around this in the Stinger forum to see if anyone out your way would volunteer.

Thanks again for all you do!

Seems pretty normal to me here.

Oops. Will upload new ones later.

Just finished installing it all, New plugs gapped to .022, JB4 + fuel control wires, and the Fuel-It E85 Sensor.

Did a short run on Map1 then Map3 does anything seem out of sorts?

Car felt good no breaking up that I recall noticing. My only question is on the Fuel-It sensor. It seems to be registering with the JB4 as the E85 gauge populates data, but in the Fuel-It install guide it mentioned the following

Quote:

Within the JB4 app on the ethanol/E85 settings set “signal scaling” to 100,
check off “JB4 15/16 FlexFuel Input”, and save the settings. When active you should
see the E85 mixture appear under the “E85” parameter in the JB4 Mobile app.
But I'm not finding those settings anywhere. Maybe those instructions are obsolete with the v10 firmware?

Is there anything else I need to do for the JB4 to make use of the ethanol sensor data?

Just before the pulls for these logs I was at ~ 1/2 a tank of gas, I put in ~5 Gallons of E85 then topped the rest off with 93.

Also not sure if these logs are long enough. It was just a shake down run and I didn't have a lot of road to work with.

snowmirage 08-13-2019 01:01 PM

Think I found the settings for the Fuel it Sensor looks like they are under WMI

I don't recall reading from anyone else running the Fuel-It sensor so I'm not sure if this is expected.

But when I pull up the Fuel-It App its giving me a reading of E30 - E34. As I understand it thats ~30 to 34 % ethanol.

But the E85 meter in the JB4 app is reading ~ 15. In settings > WMI, I set "Signal Scaling (0-100)" to 100 and turned on the slider for "bit1:JB4 15/16 FlexFuel Input" I have the Fuel-It Sensor's white wire connected to pin 16 on the JB4.

Have I not setup something correctly for the sensor in the JB4 settings?

I also was able to do a brief run on map 5 that I've attached the logs to, car seemed happy but I'd appreciate an experienced look for anything that looks troubling.

Email Terry
Most likely you need to turn 15/16 off and turn on 2/3 which may then reflect the correct values. But you should email Terry for support.
I encountered a similar issue but I also have a WMI kit where the pin in the directions wasn’t available due to the WMI FSB.
