Default New beta v341 OTS maps available for Accessport for 2015 STI



We now have new v341 maps for the 2015 STI available for you guys to test out! As we have continued to develop and test the OTS maps for the 2015 STI, we have found that the v340 maps run a bit on the rich side under full throttle. The new v341 maps address that overly rich condition. Additionally, the Stage2 maps have a slight tweak to ignition timing under full throttle. Overall, the cars should be more happy at higher RPMs while carrying a bit more power to redline.

All variants of the following maps have been updated:
  • Stage1
  • Stage1+SF
  • Stage2

The new maps are available for download here: 2015 STI v341 OTS Maps

We appreciate your feedback and thank you for your support! If no major issues are found, these maps will be marked for release and included as part of a future maintenance firmware release.

If you would like to post a log to review, please include your car's year and mileage, your exact mods, the name of the map being used and the general conditions under which the log was collected. Also, please add Injector Duty Cycle to your datalog list so we can keep an eye on that as well. Online services like Box, Google Drive, Dropbox, etc. can be used to host files if you need a good way to share datalogs - please just be sure to mark the file as available for public download!

Loaded the Stage1+SF ACN91. Logged the IDC at 89% on a 3-4 (to redline) gear pull. Can I use the Stage 2 map if I have a CBE? Or do I need to run the Stage1+SF.

Car parameters:

No other fueling modifications.

Environment parameters:

Can you post your log up? You will want to stick with the stage 1 + map. Only time to use stage two is with a downpipe. Did you notice any difference running these beta maps?

You have a minor timing correction in Fine Knock Learn that is working itself out through your logs and then pops back up at the end of your second log. Not horribly concerning, but keep an eye on it to make sure it doesn't get any worse (like -2.0 to -2.8 or so). You also have a little boost spike after the hard shift, but that is pretty common. Overall, everything looks good.

Thanks on the feedback Chris. I'll keep running this tune, see what happens. Def will be keeping an eye on the fine knock learn.

here are my logs from the Stg2 v341 map
Car feels great, but there is a knock event early in log 2. Should this be a concern?

mods:
Invida Catted Downpipe
Nameless Catback

log 1 was just after flashing
elevation: sea level
temp: 70F (with humidity)
https://drive.google.com/file/d/0Bxz...ew?usp=sharing

log 2 was 300 miles after flash
elevation: sea level
temp: 60F (no humidity)

The first log is awesome....the second one, not so much. That timing correction in the second log is learned from a previous event. It's hard to say if the car is unhappy during a previous WOT pull or perhaps the engine was lugged in a high gear at a low RPM and got upset? Could be a case of bad gas if you filled up between the two logs? The car has higher calc load and MAF v in the second pull. Long shot, but you may have developed a small leak in the intake or TMIC piping. Those are all just guesses though.

I would recommend resetting the ECU (which will clear out that learned timing correction) and watch the car closely to see if A) It happens again and B) Under what conditions does it happen.

Just turn the knock sums on and if they are no incrementing during a WOT pull its from a previously learned event and will start to decrease.

I recently downloaded this and it seems that my car runs smoother; less peaky. Also, with the Stage 1+ v340, my car would run up to 20.5 psi...with the v341 beta, the most I have seen is around 19.2 psi.

2015 STI with approx. 14k miles; all logs in DFW area

-Magnaflow Cat-back
-Stage 1+ Tune

Stage 1+ v340; temps in the 40's/50's

Prior to the v341 I was using the v340 Stage 1 93 LWG map as the normal wastegate was seeing consistent psi in the high 18s. This map seems to have brought the psi level to exactly where it needs to be. Also absolutely no FBK and FKL during WOT only saw a couple instances in the past 200 miles where I saw some FKL during low load part throttle.


Here is a couple data logs:

Stage 1 93 v341 @75-80*:

I've been running the 93 LWG map and it's been running pretty nice, logs looking good as well.

Here are a couple logs from the V341 Stage1 SF+ LWG maps. I tried the standard V341 Stage1 SF+ map but would get peaks of 19psi. The LWG maps keep the peaks down to 18.1. The V340 Stage1 SF+ LWG map would peak at 18.3psi.

Log 1 - Stage 1 + SF V341 - about 60*

Log 2 - Stage 1 + SF V341 - about 55*

Any idea on if/when these maps will become final, and release?
