Oh okay I needed to read the manual I guess. I didn't realize I had to choose an on-screen parameter after I set it to log. I was stopping there thinking I was doing it wrong. Thanks will try it again.

Do everything VN just covered, I usually go the RPM channel to log since I like to start my logs around 2.5/2.75k. Before I start the pull, I want to make sure that the AP is actually recording the information.

To each's own tho

Yup, +1 good point

there is a slight lag between hitting OK to when its logging. i usually wait a couple seconds. to ensure its ready to log.

You are right!!! I did the conversion it is somewhere between 93-94 AKI.

How does the fuel help with my datalog and timing pull?

The higher the octane the more resistance to knock/timing corrections you have. Running a map designed for 93 on 91 will result in timing corrections. Running a map designed for 93 on 93 will result in good logs with good power.

Yes Wiki has great info.

Since I am ACN 91 AKI, I can't run aggressive tunes, Sport or Agg. So I mix 3 gallons of E85 to run Agg. MAPs. But I'm pro tuned now.

Unfortunately this is the best I can get in the country and as far as I am concerned I am running 93 Map with 93 fuel.

We have 91, 95, 98 RON and I always run 98 RON.

I think the weather is as bad (summer), around 25-30 degrees C.

Is there nothing else I can do about the timing pull beside getting FMIC?

I've sent the log to COBB and still waiting their reply.

Based on the logs you posted before (when comparing stage 1 and 2) your logs really good. I didn't see any corrections to be concerned about.

I think Cobb toned the race maps down a bit on the 4.03 maps but, I haven't opened up the map in ATR to take a look and confirm if they have or haven't.

It is toned down. The timing is less aggressive than the previous v402.

I just checked it out in ATR and 4.02 and 4.03 are EXACTLY the same as far as load target and timing are concerned.

Just do as the site suggests, load up the map and datalog it to see how it looks.

I loaded those maps (IJE0S) and my timing always peaked at around 9 degrees near redline where as in the v402 it always peaked at around 13 degrees.

Truth be told, I only tried v403 for about a day as I preferred the older map and maybe I didn't let it adapt though...

A good guideline is, 3.38* or less across 3 or less cylinders. For timing corrections. If you start seeing higher.timing pulls consistently on the same cylinder, you can swap coils and see if it follows, if it does get a new coil, if not maybe a new spark plug. Even the stock setup.has timing pulls. I was getting higher than 4.xx on cyl 2, eventually. I got a misfire, swap coils, it followed, changed the coil, fixed the issue.

You are good.with 98 Ron.

Just for kicks, do you have VD graphs showing 402 vs 403? That seems to be a big difference. Let it adapt, usually a newer version means smoother and happier car, but maybe not. It shouldn't take much for the car to adapt to a new version just a couple WOT.
