Factory Tune logs
 

I just wanted to gather some logs of the stock tune(s) as reference. Since I reflashed the stock A01C rom recently getting ready for some warranty work (oil seepage out of driver side camshaft/cam chain cover). Would really like to see the differences between 91 and 93 octane on the stock tune, also how they have improved/changed in the newer B01C cal id roms.

ROM Cal ID: A01C
Fuel: Shell CA91 octane
Mods: Drop in air filter, all else stock
Ambient Temp: 68f

Log 1 with oil and intake air temps being logged in place of cam timing:

Log 2 cam timing being logged 15 minutes after the first log on same road:

In the cool temps there is virtually no knock being registered under WOT pulls (conservative stock ignition timing table). I only captured a bit of tip in Knock Correction (-1.06*) upshifting to 5th gear after redlining 4th. A lot of tip-in knock when throttle was even slightly increased at off idle to mid-range RPMs. It was easy to induce the IAM to be dialed back under regular driving conditions. Too easily. Fuel trims were above plus 5%.

Zoomed in on WOT pulls:

After reading about how the ECU supposedly pulls power at oil temps above 100*C or 212*f, I took some more logs in different oil temps. Same set up as before. Bone stock. Forgot to include that the oil being used is GC 0W-30 synthetic.

Starting 3-4-5th gear pull from 188*f oil temps ending 204*f, 77*f ambient:

Starting 206*f ending 221*f oil temps, 69*f ambient:
http://datazap.me/u/solidone/stock-a...6043-6070-6106

Starting 230*f ending 240*f oil temps, 69*f ambient:
http://datazap.me/u/solidone/stg1-st...4401-4424-4472

So far, at least up to 240*f oil temps, there has not been any difference in ignition timing advance applied in the absence of kc or flkc. But in the log with oil temps starting at 230*f does show a little bit more knock correction activity in all 3 gears.

There is about half a degree difference between the lower temps.

FWIW, a log I looked over recently I saw a couple of degrees pulled due to oil temperatures. It only shows up as less ignition timing, not FLKC. The boundary seems to be what I thought it was, 110C. It may be 115C but I know that up to 110C it runs the total timing from the tables. The car in question over the last week is in Germany, thus able to do high speed runs and maxed out at over 125C oil temperatures.

If I remember, I'll post some comparison later when I'm on my laptop.

This isn't factory tune, but shows timing fairly consistent timing for increased oil temp in the same session, same rpm, same engine load. The oil temp timing retard will be the same as factory as that functionality isn't accessible.

Yes there was an half a degree of difference at 4500 rpms where the hotter oil temps logged .5 degree more timing than the lower temp then at around 5000 rpms the cooler temp logged .5 degree more advance than the hotter log. Other than that, it's pretty much the same if you add back the flkc corrections.

I would love to see what you are getting in your logs on the autobahn. Also anybody with different cal ids. :)

Wait... in your logs at 7100rpm where you marked it's showing 31.5 degrees of advance with 210 oil temp but at 239 oil temp there is 33 degrees of advance. So it's increasing the ignition advance as oil temp rises not retarding it. or am I reading that wrong?

That's correct, so i wouldn't go counting 0.5 degrees here and there very much

would agree cannot see a timing retard as oil temp increases, that diff may be due to engine load difference. The intake air temp is different to but is below the factory threshold for retarding timing , unless @Wayno has adjusted it :-). you alvance multiplier is 0 ??

Yeah I noticed that at the start of the session when I started the car. Everything else was normal though.

Here's another one with same parameters - marks around 6200 & 7200 rpm, 1.25ish load, 70-75F IAT, no IAT timing compensation because I didn't add it to E85 tune.

99C/210F (same as previous post)

Why is your IAM at 0???

I would also like to request some logs of the stock tune with 93 octane or higher, if anyone is up for it. :thanks:

Just a bug

i have a short one on 100 ron aussie fuel if you want it

The "bottoming out" of the afr sensor at 12.17 is interesting. It's flat and steady enough to indicate that it's the limit of the sensor. I wonder why on aftermarket tunes it bottoms at 11.25? Is the scaling changed at all in aftermarket tunes?

Yes, mine goes as low as 11.02. I think that may be the limit of the sensor as I've just checked my scale and it has 2 points below that (11.0 and 10.58).
