As far as I can tell, this is the "ping fix"




Basically they just cut out 1 degree of timing from the higher load areas in the base ignition map. If you have a 2004 STI, you can just load the last 2004 STI ECU calibration (AJ243, A2ZS710J) with Openecu tools.

Stick to 93. Why would you want to get rid of the one thing that gives the early 04 STi's an advantage!

They make more power than the later ones...

I had the first 04' STi off of the Lot. My STi would ping "sometimes" on hot days, at WOT, after sitting in traffic. Had it flashed, I've never heard it ping since. (but I do think its a bit slower ever since.... )
