Hey guys,

Just got the new 17' si and want to flash the ecu with the new +9psi in sport mode calibration... It will be my first time flashing an ECU on my own so if there are any comments or some guidance from the honda family it would be much appreciated???

- Will I need further tuning after the flash is complete??

lock the FlashPro to your ecu
load up the calibration onto the FlashPro then plug it into the car.

once you got you got it plugged in
press and hold program for 1second then release.
wait 3-5mins til the red light goes away on the flashpro
turn off the car when it's done flashing then start the car up

Do you have a laptop? Plug the FlashPro into the car OBD port and the USB cable to the laptop/FlashPro. go to the software click on Online then lock vehicle.

You should not need any tuning afterwards unless you have an aftermarket intake. You might need one then

Great! and no nothing done to the car yet just stock, but I heard this flash does quite a bit in terms of HP and toque. I am just trying to make sure I don't blow up my motor, by doing too much!!
