Tuning Alliance Posted September 29, 2012 Share Posted September 29, 2012 Well after reviewing the fifth generation legacy tunes (stock and cobb), I noticed there is still timing being added to cylinder #4. Although the idea may be to concentrate knock to that cylinder, I do not believe it to be beneficial. Perhaps less than a degree may accomplish that, yet the tunes are adding over 2 degrees in some areas. http://legacygt.com/forums/showthread.php/tune-safety-warning-05-06-cars-urgent-101428.html?t=101428&highlight=cylinder+trims When I raised this issue in older legacy's, Cobb concluded that running negative timing in Cylinder 1 & 4 (dog leg cylinders) was the best solution. All TA maps have this fix and I'm guessing that if you contact Cobb, they will revise there maps. Just like they did in revision 118 Also there is some additional timing in cylinders 2 & 4 on various newer WRX's and STi's. Beware. Another great reason to run TA maps, we stay on top of these things. Contact us for all your tuning and performance parts needs! Etuning the legacy community since 2008!

Max Capacity Posted March 14, 2013 Share Posted March 14, 2013 Hi Mike, just want to let those who find this know, my ej257 is almost at 20,000 miles with your tune and still runs great. Seems to be a lot of chatter about how bad the ej257 with the oem pistons in it.

Hepy117 Posted May 9, 2013 Share Posted May 9, 2013 Sorry to bring an old thread back to life, but, so essentially the 5th gen oem tune is "dangerous" and we should go for a "stage 1" tune from TA or someone to get this advance taken care of?

Yes, the stock tunes closed loop delay and additional cylinder #4 timing certainly increase the odds of knock incidents. Contact us for all your tuning and performance parts needs!
