RSX ECU/K-pro and throttle body swap
Would it be possible to ditch the VSA modulator, throttle body and ECU in the TSX in favor for the RSX-S throttle body, and ECU + Hondata K-Pro into the TSX? This would open up a world of possibilities in terms of modding.

Better yet couldn't you could use the throttle body from the I4 Accord K24 along with the ECU/K-pro from the RSX using the TSX basemap? I've been trying to research this ever since people started swaping the K24A2 into Civic Si's and RSX's.

Thanks, after studying the full dynamics of the VSA system, I feel compelled to keep it now... I guess I'll just wait until Hondata releases something specifically for the TSX.

let us know what you find.

Be ready to do a complete wiring harness swap as well....the pin outs on the ecu are different. I am tryin to get the skematics of the RSX S and the TSX wiring harnesses and ecu pin outs to make an adapter...we will see what we can come up with. Will take me a while though....

Let me help a little bit here. In the course of our experimentation we have done exactly this.
We used a RSX-S ECU and an Accord throttle body. Over half of the wires in the wiring harness needed to be moved for the ECU to work.
This is what you lose:
Speedo
Tacho
Fuel gauge
Coolant temperature
VSA
Cruise control
and probably air conditioning, but this was not tested.
What you gain:
Throttle response - by eliminating the drive by wire
Tunability for NA or for boost.
ABS is not affected.
You would need to add a RSX oxygen sensor for accurate air fuel ratio readings..
We will not be able to make the RSX ecu drive the instrument cluster. If you want to make a race car out of a TSX, then this is a good solution.

Edit: I was thinking about DBW. I need to look at the manual to confirm...

Ok Hondata you know there are alot more people out there in the world that love your products. They just arent here on the boards. Please make a K pro for the k24...What if we even had a fund raiser for the R&D??? Come on hondata give us something PLEASE!!!!

And make sure you make a reflash for the AT
