I also updated the 1st post quite a bit. I did a cut and paste on some of the info and included page numbers for relevant PID discussions. If you get a chance to look I'm open to feedback on how to improve it!
Won't be able to look until later (busy peeling crap vinyl job from tails...plasti-dip time), but I imagine it will be spot on adding to the holiness of the grail as it be...lol

Hi all, I asked the question in the FORScan Forum (you can look that up in the FORScan forum as its not that big just yet) and even the guy behind FORScan does not know the algorithm. But he did point out for me that the range for the reading is -200% to 200%. So far only the FordST Forum (http://focusst.net/threads/want-to-data-log-or-monitor-your-focus-st-this-is-how.161/) had some mention of the range whereby -1.0 (-100%) = High Octane, and 1.0 (100%) = Low Octane RELATIVE to your car's tuned octane rating. I suspect you should not expect to see 100% consistently, because what i understand is that the car ECU will re-learn the relative octane after acceleration when you decelerate. The other thing to note here is, you should be expecting a close to 0% range when filling your car up with the car's recommended fuel octane. i.e. the car's default tuned Octane.

I also looked into stuff like FoCCCus (a Ford Focus ECU Editor and Reader) to find that even though the car manual and dealer says that the car is designed for 91 Octane Fuel and 10% ethanol blend fuel, the actual ECU setting was 95 Octane! So, I will also caution that finding what the actual fuel octane setting in the car is not a simple matter of asking the dealer or reading the car manual.

For me, this PID is most useful to gauge your fuel octane RELATIVE to what the car is tuned for. For example, my car is tuned for 95 Octane, if I fuel up with good quality 91 Octane Fuel, I see the learned octane % hover around -5% to 50%, with I fill up with so called '94 Octane fuel' (blend fuel with up to 10% ethanol), the learned octane % actually jumps far to the 80% range (indicating lower octane) which makes sense, since the actual fuel IS lower octane, but because it is blended with up to 10% ethanol, it is then claimed 94 Octane. I also note that the LTFT (Long Term Fuel Trim) will show a reduction in % by up to 2-3% when filling up with 91 Octane fuel versus the so called 94 octane blend of fuel and ethanol.

I hope this helps.

And to make it clear once and for all, the Learned Relative Octane Adjust does not tell you what the octane rating of the fuel. AKA 93% Reading on the PID is NOT 93 Octane. In fact, no one can confirm what the exact algorithm is just yet, other than Cobb Tuning that seem to have figured something out. Wonder if anyone has ties with them that can ask what algorithm they use.

95 RON is regular unleaded.

The number at the pump is an average of

Research Octane number(RON)

Motor Octane Number(MON)

In Australia it looks like 95 is equivalent (roughly) to our 91 octane...?

Previous 2011 Tuxedo Black SHO w/PP - 12.89 1/4 Mile

FoMoCoSHO

Without knowing the MON, there is really no way to tell.

From what I've read the 95 usually correlates with regular unleaded.


FoMoCoSHO

I just reset the range to -200 - +200.

Let's see what happens.

Weird, on FORScan I have never seen a negative number or above 100%.

In case you guys didn't know, there is now a Torque add on to extend your display to a 2nd device. I'm gonna go buy another nexus today and try it out.

SHOdded

Where do you plan to mount the device, FoMoCoSHO?  Sidebyside, or toptobottom?  Interested in pix :)
2007 Ford Edge SEL, Powerstop F/R Brake Kit, TXT LED 6000K Lo & Hi Beams, W16W LED Reverse Bulbs, 3BSpec 2.5w Map Lights, 5W Cree rear dome lights, 5W Cree cargo light, DTBL LED Taillights

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Figuring a permanent mount for the tab (not sure where yet) and a secondary vent mount to the right of the wheel for the phone which has been my favorite mount so far. ( and I have tried a bunch, lol )

That's the brand window mount I got. Like it, pretty solid.

I could do 2 vent mounts left and right but after the nonsense I found myself in the middle of last night, I want at least 1 camera able to record.

Yeah, I was pretty impressed, just don't move or dismount often or they won't last. I'm on #2.
