03-05 Accord Reflash

03-05 Accord K24A4 reflash offers 3whp from 3700 to 4200rpm, 5whp from 4250 to 4550RPM, 7whp from 4600 to 5100rpm, Then 13-17whp from 5100rpm to the rev limter at 6500rpm. Ktuner Reflash allows you to keep stock driveability. This reflash is designed for STOCK cars. There were NO aftermarket parts on this car.

03-05 Accord reflash for TSX swapped motor. This reflash is tuned for a TSX motor in a 03-05 accord. The factory ECU mapping will NOT drive the TSX motor correctly and you can NOT swap a TSX ECU into 03-05 accord (no DBW). This scales the injectors to the larger 310cc, changes the Cam angles to correct angles (tuned, not factory), fueling and timming are also adjusted to make the most power while being safe. 

This supports the 2003-2005 accord K24. The ECU would have to be the following:

Manual:
37820-RAD-A01 through A04
37820-RAD-L01 through L04
37820-RAD-306
37820-RAD-316

Automatic:
37820-RAD-A51 through A54
37820-RAD-A61 through A64
37820-RAD-L51 through L54
37820-RAD-L61 through L66
37820-RAD-L71 through L73
37820-RAD-305
37820-RAD-307
37820-RAD-315
37820-RAD-317
37820-RAD-325
37820-RAD-327
37820-RAD-329
37820-RAD-415

Automatic ECUs will run a manual vehicle with no issues.

You would have to ship in or buy a KTuner ECU for 2003-2004 accords.
