dreadangel thanks for that. makes sense perfectly.

well the rbc intake manifold has a different angle output that the stock cl9 one. so im not going to have to wait untill the intake manifold and throttle body go on. after that ill have to look at purchasing an intake to suit.
once all this is done the flash pro with the tsx ecu sounds good.

the only thing im questioning is it was stated earlier, the ecu needs to be suited to the cars immobilizer.

on so say i purchase the ecu and hondata (and the adapter cable) once i unplug the stock ecu and the plug in the new one, am i able to start the car and drive to a honda dealer? lol this is a dumb question, but as i said i have no experience with ecu's etc.

If the car does not start, what am i meant to do?

and imo - honda are absolute clown shoes - what do i say to make them understand what i need them to do...

thanks again guys.
