Default 2005 WRX 1/4 mile data log,, stage 2 93 v310 tune

Hey all, I just loaded a stage 2 map tune on my AP; the car is an 05 wrx with the stg 2 v310 93 octane tune. I was wondering if anyone can take a look at the file and let me know what you think/any issues? I would appreciate it! BTW you will see 1st-4th gear pull (barely any of 4th tho before I let off).. I launched crappy as you can tell by the rpm drop at the beginning.

You need to allow permission for people to see your google doc.

A data log this long only makes things harder to read in my opinion and is not necessary, but I'll do my best.

Are you using launch control? This may explain some of the fine knock learning that you have. Doing another appropriate log now to see if it lowered would be good.

Hi Mark. Log looks fine except that you are underboosting. The fine knock learning is at lower load - not something to be generally concerned about. I would get a 3rd gear run from 2000 RPM on up (if you can do so safely). This is a good baseline to compare how boost control is working. You may need to reflash to the high wastegate (HWG) version of the map.

Yeah I did have launch control on. I will do a normal 3rd gear pull tomorrow.

Ok Bill, I will try a 3rd gear pull tomorrow. I was using LC so that could be the knock I guess. I can actually flash it tomorrow to the hwg tune and do both pulls so we can compare between the tunes. Thanks.

ok 3rd gear pull... I did from 2k rpm until redline... I swore I had WOT at the beginning but the throttle position doesnt say 100 until a higher rpm as you'll see, so if I did it wrong again, let me know and I can do another one later.... Thanks in advance guys!

The log looks fine except, even though you were not at 100% throttle earlier in the run, you are still underboosting. I would download the high wastegate (HWG) version of your map, reflash and do another run. Make sure the floor mat hasn't creeped underneath your gas pedal (which can also be dangerous).

Ok sounds good Bill, thanks. I will try sometime today to do that.

here is my 3rd gear pull with the high wastegate stg 2 map. The car overall does not backfire at all like it did with the other tune, so hopefully the datalog looks good. Let me know and thanks.

When was your car backfiring? Do you have a catless downpipe?

You are still underboosting. Not uncommon with these cars - you may have to tighten your wastegate arm a bit to get closer to your target. Start with the normal wastegate map and try to do a turn at a time and then log. There are various DIY threads about the wastegate arm on Nasioc.

On these older cars, it would also be a good idea to get a pressure test of the intake tract done to make sure there are no intake tract leaks (also DIY threads about this for those with an air compressor). Also, drive for a bit (say a tank of gas), on the same map (and without resetting the ECU) and then look at your A/F Learning 1 A, B, C, D values via the AccessPORT live data to make sure they all fall within +/- 5% or so.

It backfired/popped only seldom/random,, and only would do it when I was letting off the gas (when driving it easy and not in boost)... I do have a catless invidia downpipe.

I will look into the wastegate arm. And I made a homemade boost leak tester for my 60mm turbo for a different car, so I'll mod it to l put on this car and test for leaks too... Honestly might be my turboxs bov too,, which I may adjust the spring rate in that too, if needed. Thanks again for the tips.
