What is the current value? What kind of gas do you use?

 

Current value is 0.00 it's always been 0.00. I use 93 octane.

 

How long have you had this current tune on? Have you tried forcing it to change?

 

500 miles. Don't know how to force it

 

Search for it. it's here I'm mobile or I'd link it for you.

 

I like to have OAR and ign correction gauges up while forcing it. In 5th or 6th gear, maintain 6-8psi for like 20 seconds or so, or however long you safely can. You should see your ign correction go up to like 3-4 during this. After a pull, you should see a change. If not, the gas may not be that great.

 

Same thing with me. I've had the same tune for around 3 weeks. Stuck at 0. Driven probably more than 500mi, tried "forcing" it. I have filled up with Shell and Mobil.

 

I'll try that. I don't know if it can be the gas, bc I've been trying as many gas stations as I can

 

Mine is the same. Just got the AP from an SCT and set it up to show OAR and ign correction in 1&2 and all three of those have never worked or changed from 0. Other gauges like air temps, boost, rpm, stuff like that works fine though. Don't know what I'm doing wrong. I'm running one of Randy's tunes

 

The ign correction never changes? Not even under wot?

 

Nope, none of those things have ever changed from 0. I tried the 5th or 6th gear holding small amount of boost to try and force the OAR to change but nothing. I only run top tier 93 octane. Maybe I should try and uninstall and reinstall the AP?

 

Do you have any datalogs of you wot pulls?

 

There is an enumerated PID that shows when the OAR is in listening status. That's a lot easier to watch than guessing by boost and corrections. There is another that shows how much correction is being averaged and applied.
If you've updated firmware or did a kam reset recently, it may take a while before the oar activated again. Can't say why, but Braden has mentioned it in the past.

Which is the PID for when it is listening. This will help when I reinstall after getting my recall done lol.

 

Herpaderp lol. How have I never noticed this!?

 

I don't have any logs yet, was actually going to try and get some tonight or tomorrow. I'm assuming the firmware was updated recently before it was shipped or something maybe thats why the OAR isn't working yet. It has only been on my car for a day and I haven't driven a lot yet. I'll wait a while before I worry about anything I guess. Thanks for the help!

 

I think Braden called it a green reset. Happens after some firmware updates and some cars take quite a bit of driving before it activated again.
Otherwise, there are 3 min/max thresholds for the oar to listen. ECT, load, and rpm. IIRC, the mins for it to start listening are 175*ect, .375 load, and 1200 rpm on stock and OTS maps.

Guys, don't set the OAR in 6th gear. That's not a great idea. Too low of RPMs in too high of a gear is not good for the engine. You can do this in 4th gear and it's much better for the engine.

To the OP: if you don't see the OAR change that means that you are not really driving in a zone of the program that will impact the OAR and cause it to change. This is why you see these kinds of posts. Part throttle boost with positive ign corr values is what triggers the OAR to change. And you have to do that for around 7 seconds straight or more. Most people don't drive like that so it can take a really long time or never change at all if you don't go out of your way to set it.

 

You can do this in 4th gear

.

I can confirm this. I was having hell in 5th for whatever reason, changed to 4th just like for datalogging and it worked the first time.

 

I got all my shiz working today on a drive around the city. Figured out that 4th gear works much better :smile:

 

Matt! Great avatar LOLOL. Need to update that sig, though.

 

I'll have to give this another go. I drove to a remote road and tried this in 4th and 5th gear and OAR didn't budge in either direction. I didn't feel comfy with trying in 5th gear anyways, Evos didn't like high load in low rpms either.

 

Mash the throttle, it will move...

 

Newbie question.. What does oar represent.

 

Octane Adjust Ratio Learned value is what's being discussed here. The overall value is a number that represents the general state of the relationship of fuel quality to programming.
