Ok. This maybe odd one or not. I dont have problem reading E85 on HPtuner scanner. What im trying to do is read E85% on AEM X series OBD2 digital gauge 30-0311. I can read a lot off info but not E85 %
In AEM instructions PID for E85 is 52. Now qustion is is it possible to add that PID to my list
I have 2016 Yukon Denali 8 speed
Thanks
Here's what the AEM manual says...
"This manual says that a PID is supported but I can't find it when I scroll through the PID list using the PAGE
button.
Your vehicle may not support every PID that is supported by the AEM OBD-II gauge. Upon power-up, the gauge will query
the vehicle for a list of the available PIDs and display the ones which are supported by the gauge. If the PID is not listed
when scrolling through the list using the PAGE button, then the PID is not supported by your vehicle."
So there is now way to get that PID show up on this gauge grrrr. I gont want get another darn gauge just for that. This one was nice i can see different sensors but not this one
Get a Fuel-it Bluetooth module and app. Then you can just plug it inline with your Flex Fuel sensor under the hood and load the app on your phone to see fuel temp and E percentage. Easiest way without adding another gauge.
Interesting, ok than question with this bluetooth ONLY flex analyzer, do i have to bring 12v and ground to this adaper or is it just plug inline between flex sensor and OEM connectorOriginally Posted by TriPinTaZ
According to the Fuel-it instructions, it simply plugs in to your sensor and requires a dedicated switched power and ground source.

Should be able to use the power and ground from your flex fuel sensor, can't imagine current draw for it is much.
Contacted Steve at Fuel-it. He says if i have flex sensor thats hooked to the ECM i would need BT/Raw signal output 50-150hz and them one doent need 12v and ground and its installed between flex sensor and oem connector
If i have stand alone flex sens9r /one tbat ecm dont read it i would need Bluetooth version and that one needs 12v and ground
All you need is the version that has raw 50-150hz output and it goes inline between the flex fuel sensor and the harness. That way it gets power from the coil pack and passes the raw signal through to the ECU. Super easy.
I see. I also found Innovate ECF-1 . Anyone know anything about Innovate Flex gauges. They have 3 different flex gauges, 2 of them 4 in 1 and one is Flex and fuel temp
Fuel it kit came in. I only needed BT raw 50-150hz version but it came with extra plug for JB4/0-5v version. It was simple plug between oem harness and flex sensor now i got E85 % and fuel temp on my phone. Checked scanner and reading was 80.4% on Fuel it app 81% since it shows round #s
Ok. So it is possible to splice aftermarket flex gauge on GM flex sensor. It works
First of all i installed Fuel It Bluetooth Raw signal output 50-150hz. Scanner shows 82.4%, Fuel It app 81-82% for its very close. Than i installed Fuel It Flex harness extension, shorten it some since 48" was too long, splice male plug from 2nd Fuel it extension i have using only white signal wire into 1st extension white wire. This way im only tapping into signal and not adding 12v and ground to existing flex sensor that already have that from the ECM. Installed Innovate ECF-1 4 in 1 gauge, also hooked Innovate fuel pressure gauge on top of flex sensor with adapter that comes with gauge
Scanner still shows 82.4 %, Fuel it 81F and innovate gauge shows 81.5%
