Long Island Legacy Posted January 14, 2009 Share Posted January 14, 2009 Ok this is athird gear pull all the way to the rev limit. Someone please analyze this for me there is so Knock correction, but my boost still seems low and does not seem to hold well at all in my car. Compared to other logs my boost tappers very fast. My mods are Perrin 3" catless DP,Stock Cat back Perrin TMIC,Stock VF46,Cobb OTS Stg2 map v103 Firmware v1.3.0.0-8108. http://www.datafilehost.com/download-51f21b32.html Link to Log.

AWDxBOOST Posted January 15, 2009 Share Posted January 15, 2009 boost drop looks fairly normal to me...the leg's tiny turbo tapers just like the wrx your knock correction sucks balls tho...but i havent seen too many datalogs of the ots maps Link to comment Share on other sites More sharing options...
FLEXN LegacyGT Posted January 15, 2009 Share Posted January 15, 2009 It appears that that tiny turbo, even though they do taper off, is taking way too long to hit 15psi(3800rpm. Obviously your spiking at 18psi but with shuch a drop off you may want to check for leaks. Link to comment Share on other sites More sharing options...

This is achieved with a catback exhaust which i do not have. I have the stock catback so that could be a potential bottleneck preventing me from hitting target boost right?

AWDxBOOST Posted January 15, 2009 Share Posted January 15, 2009 maybe, are you sure you have no exhaust leaks? Link to comment Share on other sites More sharing options...
Long Island Legacy Posted January 15, 2009 Author Share Posted January 15, 2009 maybe, are you sure you have no exhaust leaks? I have a minor leak where my downpipe adapter 3"to 2".5 i think mates to the stock catback. i have the wbr adapter so u can use a full 3 inch dp with a flat 3" flange with your stock exhaust.

mickeyd2005 Posted January 15, 2009 Share Posted January 15, 2009 That's not a leak. That's just how the turbo responds when given that type of WGDC control. Plot MRP on Y-axis and WGDC on secondary Y-axis and rpm on X-axis. If you overlay target boost on it, it'll even be more obvious. You'll see it.

mickeyd2005 Posted January 15, 2009 Share Posted January 15, 2009 The 07+ LGT uses a smaller restrictor pill than the 04-05. It's easier to overboost especially in 4th gear. http://i141.photobucket.com/albums/r69/mickeyd2005/untitled-34.jpg Link to comment Share on other sites More sharing options...

Long Island Legacy Posted January 15, 2009 Author Share Posted January 15, 2009 so how does this log look for a stg2 Setup. is that knock normal,im going to log one with my special octane boost mixture. Link to comment Share on other sites More sharing options...
Infamous1 Posted January 15, 2009 Share Posted January 15, 2009 No knock is normal, you also didn't capture it in the log. Link to comment Share on other sites More sharing options...
Long Island Legacy Posted January 15, 2009 Author Share Posted January 15, 2009 No knock is normal, you also didn't capture it in the log. I have like -1.5 Knock correction in the log. Link to comment Share on other sites More sharing options...
Infamous1 Posted January 15, 2009 Share Posted January 15, 2009 I have like -1.5 Knock correction in the log. I see that, but that is not where it starts at, the log begins with -1.5 KC. Link to comment Share on other sites More sharing options...
RdiggA Posted January 15, 2009 Share Posted January 15, 2009 Keep in mind, you are running a OTS Cobb Map. There not that great at all, the difference between an OTS map and even an E - Tune is ridiculous. I will be looking into a protune soon which will make even more a difference after my headers. Get a tune and you will enjoy the car much more. Link to comment Share on other sites More sharing options...
