Torque PIDs...Take 2

[FoMoCoSHO]

So has anybody figured out what the LOR # correlates to?

Obviously something with the octane...

It just sat at 100 with the 13 no matter the blend, but the 15 it has been as high as 129 with an unknown fuel octane/quality.

Are you still stock? In my experience LOR starts around 129 and then heads down to 100 as it learns. I don't know that it actually represents percent Octane but the fact that it is learning. Once it hits 100 it will stay there unless you unplug the battery for a length of time or tune it and then it will start over. That is the best I have been able to figure out and it is just a guess honestly.

Yeah, this is exactly what happened but it didn't go below 117 till I filled up with V-power.

I had a crapload of +KR before i filled up so I assume it was 87...

I would say that if your LOR goes above 100, that could mean you got a tank of bad or mislabeled gas....so it does have a good use.

Here's a nice little article on Octane Adjust Ratio from Cobb:

Wait so lower LOL is good? Mine went up when I added some corn.

same here. It was at 129 then slowly worked its way down and stayed @ 102 until I refilled.

100 is theoretically ideal per the manufacturer's POV, once the new fuel is "relearned" after fillup.  Now what fuel they use exactly to set this ratio, not sure, but fair game to say E10, as that seems to be the standard in most of the country now.  I am sure they allow some variance for quality of fuel, but the "ideal" 100 point will vary by actual fuel in use, which is where tuning comes into play, altering the fuel & spark tables accordingly.  That's why you have 87/89/91/93 and beyond tunes.  You definitely don't want to run less octane than the tune calls for, but more is ok, up to a point, for example.

Interesting article.  I found an article by Cobb for the Subaru that was pretty similar.  I could probably "adjust" the formula so the gauge indicated -1 in Torque (instead of 100%) and 129 would be "0" - at least from my experience.  That said I don't really know that the behavior we've seen exactly matches up to this on the current gauge so I'm not sure changing the scale/display really help?  I will probably try it on mine and report back.

That could mean you got some bad fuel.

The old car never moved from 100, but it always had corn in it from the time that gauge got fired up.

I will be watching the behavior as I add some corn and wood...

I'm guessing 100 is based on 93 E10 since that's what is the preferred fuel and I'm pretty sure what was used to get the 365 rating.

It would be nice if this number would scale under 100 so we could see any the effects of extra octane above the 93 threshold.

Wasn't your tune adjusted for corn though?
So I would think if your ratio never changed dramatically it would stay @100.

My tune is not adjusted for corn but I add 2 gallons to battle the winter fuel. That's why I think it shoots up to 129 then once it learns/adjusts what's in the tank it goes back down.  I'm a newb when it comes to blending so I'm prob wrong. Lol

Initially no, I ran it stock.

These are working on the F150 also. Just a heads up.

Good to hear!

They also mostly work on the non EB explorer

I can't seem to get the following PIDs to work on the Torque Pro app on my phone.  Below is the data used.  Can any of you review and see if I missed something?  I would appreciate any help.

Also having trouble with tracking HP and Torque.  Lastly I somehow deleted all my custom PIDs and gauge layout on Torque Pro.  Which boost / vacuum equations/PIDs do I use?

Your AWD % looks good, do you have a screenshot or pic of the editor page? Only thing I don't see you listing above is, unit type (%).

Boost gauge I use.

PID.....22f40b
Min/max....-25/20
Unit...psi
Equation....A*.145-14.7
