Talking APR 104 Octane File

I recall running a 100 octane file but after the recent update, when I filled up 100, I went to my mobile app, realized its now 104!

Everything I understand running a higher octane map, and using lower fuel is bad. Plain and simple.

Anyone know if our engines can adjust to that lower octane? Can I run the 104 file and the car will adjust accordingly if I put in 100?

Clearly APR's site says "nope" but curious if anyone knows more about the internal workings of our cars...

I don’t have an answer for you but is this for a stock turbo or k04?

Well, I personally have run 87 on a stage 2 93 tune a few times and ran logs to see. The ecu pulls timing accordingly. If I remember correctly, the max safe number for timing pull is 5 or less. It is only 4 octane, but I've never ran logs on 100 or 104 and have no idea what the timing numbers are.

I used APR K04 3.2 102 file with RON100 fuel. First race I have ignition retards about 6 degrees, second race about 3 degrees, and third one was 1.5 degrees. I think APR ECU can adapt to poor fuel with reducing ignition time angle.

this is really great to know- I assumed as much but I also am not sure what logs I should pull to confirm.

*Stock turbo btw

You need to log ignition retards for each cylinders, ignition angle and engine speed. I don't remember groups in VCDS but if you have APR Mobile you can use "Boost and Timing diagnosis" logging.

Nice- thanks I will take a look in VCDS and if I can find something.
