UTEC Logs Showing Lean
I downloaded the Stage 2 with Uppipe map from WRXhackers. I know this map was set up to run 93 octane, but I can only get 91 octane over here in California. I ran it yesterday with no modifications to the map, and tried to datalog a few times. I kept seeing LEAN in the AFR settings quite a few times.
I know this may be a dumb question, but a person should never have a LEAN condition in any cell in AFR EVER, should they?
I have also been doing some research about using 91 octane on a 93 octane map. I have done most of my searching at all of the major Subaru forums, and I have found conflicting comments though.
In this link, which is the most current, cobraKLR suggests to reduce boost, not timing. But cobraKLR does live at 4500ft of elevation: http://www.wrxhackers.com/modules.p...light=91+octane
But in these two threads, the gerneral consensus is to pull 2 degrees of TIMING and add 0.2 of fuel to the maps.
http://www.wrxhackers.com/modules.p...light=91+octane
http://www.wrxhackers.com/modules.p...light=91+octane
What is correct for 91 octane? Is it deleting 2° of timing across the board? Or is it adding 0.2 to each cell in the fuel map? Or is it only isolated to boost?
What do you guys think?
I deleted 2° of timing across the board, changed the boost settings to closed loop. I put in 500's from 1000-2500rpm's and then 260 across the board from 60-100%, and went for a drive. I had the ABC turned out 3 turns and could only muster 15.1psi. I also added 0.2 of fuel to the entire map for safety. But man does it feel powerful throughout the rpm range.
Please give some comments.

By seeing this little bit of log, can anyone tell me if this is bad or not? YOu never want to go lean, EVER, RIGHT?
How does this log look? Good? Bad? Or right on point? Please comment.

my understanding is, youre fine. the only line i'd be concerned with is this:
4810 +0.6 3.0 26 00 00 lean +19.3 24.0 ECU. +0.0 ECU. 3.4
you should only really care about a lean condition when you are on the gas (actually, you should care about anything but "rich"). when you pop off the gas, the engine basically becomes a 1994cc air pump. i wouldnt worry too much. let me know if u wanna shoot the **** some time and go over your maps. im kinda bored lately and could use a good drive

my understanding is, youre fine. the only line i'd be concerned with is this:
4810 +0.6 3.0 26 00 00 lean +19.3 24.0 ECU. +0.0 ECU. 3.4
you should only really care about a lean condition when you are on the gas (actually, you should care about anything but "rich"). when you pop off the gas, the engine basically becomes a 1994cc air pump. i wouldnt worry too much. let me know if u wanna shoot the **** some time and go over your maps. im kinda bored lately and could use a good drive

Sure, I am down for a drive. Then you can try and help me understand the basics of UTEC logs and such.
