K20Z dyno results
For the information in depth go see:
http://www.hondata.com/dynok20-05rsx.html
05 with CAI (pink) vs 04 with CAI (blue)

And...
For the same 05 RSX tuned with an 02-04 ECU with K-Pro and adapter harness. The most astute of you will notice there are a few ft pounds and about 5 hp difference between the 05 runs on the top and bottom graph. As the day progressed every thing got hotter and we were unable to start the dyno runs at the same intake air temperature. Therefore the power dropped. The runs below were back to back (within several minutes) and therefore an accurate comparison. The runs above were taken a year apart and both were the 5th run of the day allowing for gearbox oil to warm up etc.

nice to see hondata was able to quickly solve the problem of not being able to crack the programming of the 05 ECU - by means of an adaptor harness
- thanks was quick
impressive #'s from a stock motor w/cai & K-pro

no its not flywheel hp
a dyna pack get ho off the hubs with the wheels taken off
so his whp is probably 10-15hp lower

Ah. I see.

SAE numbers = includes the temperature correction factor?
tcf = 1.00 on both graphs?

It is not eprom based but flash based like the 04. It is not known when Hondata will have a reflash for this ECU, but it will not be before 2005. The prospect of a programmable ECU like the K-Pro will be at least 12-18 months. (this is the time it took to develop the K-Pro for the 02-04 ECU) The reason for the ECU change is probably twofold and understandable to anyone who buys computers.
1) It is cheaper to make than the previous model
2) It is faster than the previous model
The 05 RSX has several major differences to the previous RSX.
The VTC mechanism is wired differently.
The 02 Heater is wired differently
The Speed sensor is now mounted on a coutershaft and spins much faster. (in first gear we datalogged 155 mph)
The throttle mounted evap bypass solenoid is gone
Most of the ECU plug wires have changed position
The speedometer is wired differently (during our tests it did not function)
Hondata is investigating the economics and logistics of making an adapter harness to allow an 02-04 ECU to drive the 05. DO NOT call us asking price and availability.
