it resets when you add more gas or disconnect the battery. so has to be done every fillup

[@CKDESIGNS]

Mine will reset randomly during a tank where it has already unlocked it. Pretty inconsistent for me. I can’t quite figure out the variables that makes it change. I know 5+mins at 69+mph does not do it. More like 10 mins for sure and even then it’s iffy. However, if I do 80 it unlocks right at 10 mins. Went back to 15 psi on my way home from that same drive.

Did the octane learning and bam, car felt like I remembered… so the thing about the “learning” is, based on your daily commute, the ecu may or may not ever learn during your drives… all my travel is city, so I never meet the “requirements” for the learn… I went a full tank of gas without it ever learning and only gave 14-15psi the whole tank. Did the learn, bam 19-20psi… crazy the system has such stringent guides to get peak boost and it can’t learn throughout a tank of gas.. either way, still love the car; just something I need to be mindful of when I wanna race and stuff.

Drove mine for about 800 miles in 3 days trying to do it, on my manual 6mt, I got it to do it once and that was after I cruised for 90mph for 10 miles. Not very reproduceable for a 6mt.

[@plasticksrt]

Don’t stay at a constant speed. Drop down to 65mph in 6th and give it 40-45% throttle for 5-10 seconds, climbing to 75mph. Let off for 5-10 seconds. Repeat for 5-8 minutes. Done. Works every time on my 6MT. The idea is that you’re constantly introducing load at lower RPM which forces the motor to advance timing to hit the torque target. This repeated timing advance is how the car learns. Staying at a constant speed may also cause timing advance, but based on elevation change etc it won’t happen nearly as fast. The owner’s manual should be revised, honestly.

[@narcoti]

​@plasticksrt thats the track learning method mentioned in the manual and it does work , works way better doing it in the lower gears.

It octane learns everytime you put gas in the car switch the car to eco mode or normal mode and drive it for 10 to 15 mins you have to stay at about 70 mph then once the little drive is done switch it to N mode and you should pull about 18 to 20 PSI

Can you try to add only 3-4 gallons to see if it resets? I'm going to buy this car but I'm held up on the octane learning... Hopefully if you add a little bit of gas here and there it will not reset. Any answer?

[@ruller213]

Any time the car detects you've added gas to the tank, it resets the octane learning because using low octane fuel (lower than 91/93) can cause knock and pinging in the motor which will destroy it over time, my work-around that makes me hardly ever think about octane learning is don't nickel and dime the gas tank, it holds like 10 gallons from empty so just go for a full refuel and take a small drive down the local highway to let it see if you put the right fuel in (octane learning), and set the cruise at between like 68 and 80 or something, gotta stay in 6th gear or higher in the dct model for the entire time, and let it go for I think about ten minutes and it should be octane learned.. only main complaint I've still got is it won't tell you when it is, or isn't octane learned so you've just gotta mash the pedal to find out

[@GeeeEm61]

What an annoying pain in the butt this is. Surely there are systems that can detect what type of fuel is in the tank without having to drive in the manner prescribed. My Renault Clio Mk IV RS200 needs 95 RON (I love in Australia), but I thought I'd test to see if it would run on E10 94 RON, as some 95 RON specified cars can do so. Within 15 minutes of normal driving with the 94 RON a warning light appeared asking me to get the car serviced. I just then fully filled the car with correct 95 RON, and the light eventually went out, but it proves sensors can be more finely tuned than those that appear to be in the N. What makes this even more annoying is that you have to do this every time you re-fill the tank when, again, the default should just be that you've filled with the same fuel unless you run the car through the learning process again.

[@4drturbo85]

So basically all you have to do is after you fill up get on the interstate set Cruz at 75 mph for 10 minutes and it will learn. Kind of retarded that we have to do stuff like this every fill up to get the max performance out of the car. Especially when I'm running 93 all the time. You would think that if you're running a lower octane fuel when you first go wide open throttle the car will retard the timing and know you're running lower octane due to knock. Should automatically pick up once you go wide open throttle to know what fuel is in the car. Would hate to fill up the car and come across someone on the road that you wanted to race in Mexico and your car lacks performance due to not have "octane learned"

[@4drturbo85]

Still haven't got it to octane learn. Only pushing 16psi. Max torque is only 250. Car doesn't seem to pull that hard at all.😢 We did a trip that was around 115 mi away and had the cruise set at 75 for like 20 minutes. 6mt EN. When are if I need a reset the PCM or something by disconnecting the battery. Right when I got the car and I broke it in and hit that 600 mi mark I went wide open throttle and it felt pretty good and I was hitting 18 lbs.. And I remember one day on my way to work It's like the car hit a brick wall when I was going in a boost. Ever since that happened months ago I haven't been able to run more than 16 lb and all I run is 93 octane.

If it “holds the boost” why didn’t you show a video of you making 2-4 gear pull? How come you never went to redline in a taller gear than first or second???? You would only allow it to pull in lower rpm’s…. No way it holds 18/19psi all the way to redline

Hate to be the "negative" guy here, but please head over to the facebook group and look at the newest post about the subject. This has been completely debunked by engineers and two prominent tuners with data. Looking at the low accuracy boost gauge and coming to conclusions about is nonsense, and the impressions are simply filled with confirmation bias.

[@ENtense]

Hey Will, thanks for your feedback on this. I know you own one of these yourself, and while you and many others tend to agree with these engineers, I am one of the owners that feels the difference and believes it helps. No disrespect to anyone who stands by their claims, it’s just my opinion that its in the owners manual for a reason. Perhaps there are reasons some people feel the difference, while others don’t. But when you drive this car daily, it’s pretty easy to feel the difference in my opinion.

[@williamrori1274]

@@ENtense No worries. I'm just data-driven. The issue and reason why anecdotal evidence is taken with a huge grain of salt is simply that the body/mind is extremely susceptible to error. For example, there was a peer-reviewed study a while back that included lots of fighter pilots with thousands if tens of thousands of flight time. Some of the most highly trained, experienced people extremely in-tune with their senses were tested on whether they could "feel" their speed, direction or attitude after some blindfolded maneuvers. Every single one was completely and utterly wrong in every case. The brain is a fickle thing. But yeah, definitely look at the data I posted, and also the comments by SXTH and Tork who have tuned these ECU's. The ECU does have a learning period, but in general it doesn't include boost and it is also extremely quick (within a minute in some cases). No need to waste gas on the highway haha, just drive normal for a few.
