I know I'm resurrecting an old thread but I have a 2005 TSX 5AT with the Ktuner and it works excellent!
I'm running an '07 ECU with the Hondata can wiring harness adapter.
The guys at Ktuner updated the software a month ago to allow the 45 degree VTC gear.
Using the '07 or '08 ECU lets you keep cruise and vsa. I picked up the ECU on ebay for $160 so it's still almost $250 cheaper than Hondata Flashpro.
