raloi Posted July 13, 2005 Share Posted July 13, 2005 I was at the dealer yesterday and asked the mechanic dude what his take on flashing the ECU for better performance was. Instead of the expected "you'll void yer warranty" lecture, he said " ... wait until about 5,000 mi before you do anything .. you may find that the car has learned to drive better .." Any thoughts on this comment ???? Link to comment Share on other sites More sharing options...
mele63 Posted July 13, 2005 Share Posted July 13, 2005 Well, I'm no expert, but from reading these boards, the general consensus is your car will probably learn to drive worse. Less clear, however, is the issue of whether the ECU is doing what is was designed to to, which is protect the engine from poor fuel and maintain emissions standards. The problem is that a clean-running, damage-proofed engine isn't necessarily a good-driving engine. Link to comment Share on other sites More sharing options...
sandwood Posted July 13, 2005 Share Posted July 13, 2005 he may have also been referrng to breaking the engine and car in a bit before flashing, but whatever the ecu might learn during that time is not comparable to what an AP or reflash will do for your car's power. reflashing the ecu after the initial break-in period (1000 miles or whatever it is) is common practice in these parts.... YMMV getting out of the legacy game Link to comment Share on other sites More sharing options...
evil_O Posted July 13, 2005 Share Posted July 13, 2005 I have heard similiar comments regarding syn - maybe it all plays a role - but it could also be pure speculation. I may be waiting until after 5K simply due to finances.. 5K+ is a good comfort level for me (personal pref of course) Link to comment Share on other sites More sharing options...
Mblock66 Posted July 13, 2005 Share Posted July 13, 2005 I did it at 2000 miles and as far as I can tell everything is fine. I don't think there is any proof out there otherwise Link to comment Share on other sites More sharing options...
PGT Posted July 13, 2005 Share Posted July 13, 2005 In several articles I have read about tuning the WRX, it seems as if the ECU does make more power as it learns. That doesn't mean that a reflash won't add on top of that curve though. Link to comment Share on other sites More sharing options...
melayout Posted July 13, 2005 Share Posted July 13, 2005 After the reflash do the Vishnu reset, to get the most aggresive timing/fueling map in 5 seconds, which you will get anyway after miles of hard driving. http://forums.nasioc.com/forums/showthread.php?t=302047 I keed I keeed Link to comment Share on other sites More sharing options...
