I cant get my AWD % to work. All the inputs are correct. Maybe its just not supported on the 13?

It could be a different module/address...did you try 761 in the header? If you did then Try leaving it blank or type in auto and see if that works.

Yeah i used the header 761. Ill try to use auto. Also is the octane PID supposed to read 100%?
All the others work perfectly and i really appreciate all the work you have done! Very impressive write up! Thank you for your time!

Yes the octane PID should be 100% ideally. I was at 75% for a bit but then switched gas stations and it actually went up to 100...
I could use a quick run down on the octane PID. I'm trying to envision the best way this could be used. It's learned octane right?ecoboostsho said:Yes the octane PID should be 100% ideally. I was at 75% for a bit but then switched gas stations and it actually went up to 100...
Right off the top of my head, gas quality...Larrylu said:I could use a quick run down on the octane PID. I'm trying to envision the best way this could be used.

Notice any difference in how the car ran?ecoboostsho said:Yes the octane PID should be 100% ideally. I was at 75% for a bit but then switched gas stations and it actually went up to 100...

Well I honestly thought it felt stronger but I have always been wary of seat of the pants testing...FoMoCoSHO said:Notice any difference in how the car ran?ecoboostsho said:Yes the octane PID should be 100% ideally.

Now all I need is a ethanol PID hah. Wish we had a sensor stock.
Are there any flex fuel taurus versions? If so would it be possible for our ecu to recognize a ethanol sensor?

There is a flex fuel Taurus I believe. Ecu could read the sensor if it had an input available, however the programming would have to be altered. So not likely it would be easy...wasinger3000 said:Now all I need is a ethanol PID hah. Wish we had a sensor stock.

So the best way I can explain it is that the car is designed to run on a wide variety of Octane from the factory. It has to accommodate for Octane as low as 87 I believe. It doesn't have an actual sensor to do this but "Learns" it from (going to speculate a little bit here) knock or maybe some other parameters. If you put in 87 the car is going to knock more than when using 93....it sees the knock and probably pulls some timing, but I'm sure there is an algorithm that maybe adds it back in while it is learning to "test" it...if the knock is there under certain conditions then the ECU finally assumes you've put in lower octane gas and switches to a different timing table with lower numbers. You lose power but the car is still happy. It then sets the Learned Octane Ratio to a number that loosely corresponds to what it thinks the Octane of the gas is. Note: If you car is tuned for 93 then use 93 etc....the tune isn't going to compensate appropriately for 87 Octane. I believe anything over 91 or 93 octane should result in 100% while 87 may put you closer to 0%...Larrylu said:Not getting it. What is "Learned Octane" and what does 75% or 100% of it mean?

Thank you. That makes a lot of sense. Now I've got to add one more gauge. That would be really great to have displayed!

Excellent! If you ever want to see it in action you can pull your battery cable for a few minutes and watch it start over at 0...Larrylu said:First test showed my usual 93 Sunoco achieving a 100% on startup. It will be interesting now to log some miles and see what turns up!
