Default Should I run the stage 1 acn tune?

I live in oregon, and while our gas is better than cali, what I mostly want out of my tune is to even out the power band and get a bit more torque. Can I safely run the ACN tune (I am guessing its less aggressive to deal with their s**t fuel) on my wrx while using oregon 91/92?

Thanks,
raiders

Yes, you can use the ACN map.

You can go conservative; flash the ACN map and datalog to see how things are. If things look good, then go to the 91 map and datalog to see if things still look good. Then, be happy

Or, you can go straight to the normal 91 map and datalog to see how things look. If everything is fine, be happy. If things look questionable, flash the ACN map and datalog to see how it looks. If you still have problems, figure out what is bad, fix it and then be happy.

The map notes will tell you the difference, but timining is more conservative in the ACN map.

You can certainly run the 91ACN map even if you are not running the Arizona, California or Nevada fuel. This will actually give you a little more room as far as knock resistance is concerned and you can do this on a long-term basis if you like.

I'm curious as to the results of data logging with both the ACN Map and the versus the normal 91 Map. I'm here in Oregon as well and I am wondering the same thing...which one should I use! Just got my AP today and Lance at Cobb Surgeline said the ACN is certainly the "safest" or "most conservative" but I don't want to use it unless it is necessary as the normal 91 Map appears to produce better results.

Or maybe someone from Cobb could answer/make a recommendation specifically for us here in Oregon...I guess I am wondering if I am risking damage by running the normal 91 Map. I see from Bill's previous post that the ACN Map gives more knock resistance, but is it necessary here in Oregon?

Best thing to do would be to get a data log. Check out our data logging video below. The 91ACN map is not technically necessarily in Oregon, but there are variances in local fuel quality (and among different brands of gas) and sometimes, some cars, are better off running a more conservative map (than they need).

Should I call Cobb to ask what exactly I should be data logging? When I purchased my AP yesterday I thought I remember being told to figure out exactly you guys want logged so you don't have to go through mounds of numbers. Or do you have a recommendation on what I should be logging and for how long?

The AccessPORT has a default logging set, which is what you want to log. If you added or removed monitors, then you can reset it back to the default list by going to "Reset Log List" under the "Monitors" menu on the AccessPORT. This is explained is the video as well as what type of run you want to try to get (if you can do so safely).

Thanks...the original video you linked didn't have have the info about run type and such but found it after watching the first video.

My one other question right now is, is it worth it to log a run if I can't get to redline (i.e. just going too darn fast for my surroundings)? I'm new at this (obviously). I would shoot for a target run but not sure if I can get it...if I get close to redline is it better than nothing?

Yes, it is still worth it to get whatever log you can safely do. Sorry about the video link earlier - I meant to post the following one, which is sounds like you've found.

Hope this works...here are two data logs I took the other night. I'd appreciate you letting me know what you think! These were run with the 91 Octane Map. Hoping you like what you see and I don't have to go down to the ACN91 Map...

Thanks.

Hi Gary. Can you convert the logs to Google Docs' native format so that there is a preview? I am not able to download the files directly with my account.

Thanks,
Bill

Logs look good. I think you are fine to stick with the regular 91 octane map.
