Is the old 02-04 dc5 ecu the same as the 05 dc5 ecu?
What's the difference besides the look and the 10 more hp?
Would 02 parts fit on a 05?

 

the new ecu is completely new. it's not even the same plug. that's why 05's can't be hondata'ed.

there's tons of differences. new cams, new intake manifold, new exhaust, new ecu, new harness, new final drive, new gears, beefier suspension
