What is the output from the RSX sensor is it the standard 0-5 volts if so then I can just feed the K-pro a 0-5 signal from my current wideband and not buy the RSX one.
The output is voltage, but the actual ecu reads a specific current range, therefore you can't use a standard 3rd party wideband. Otherwise, hondata would already recommend a wideband to use
At least I can run the current wide band in the other sensor port ( TP) and use its 0-5v output to log the 3part wide band and compare that to the RSX one.

Thanks for making the gallery public.
You desoldered the daughter board ballsy
No problem.
Yeah desoldering the board was quite time consuming you have to get every ounce of solder out of the holes and then work each pin into the center 1 by 1..very time consuming.

My sponser shop is a liked by Hondata and I have some direct contact numbers with Hondata.
I will still check.
If at least it may be possible to get it so the D. Card is not soldered in, so one does not need to desoldered everthing.
the only issue I see, is if the D board is not soldered, then they couldn't test it and verify the board is not damaged and then it becomes a liability for them.

I have mentioned this to a couple people and some seem intersted so I will post the information that I have gathered.
This is the wiring diagram for the ECU in order to make the RSX wideband work with the S2000 KPRO for 00-05. This makes it so that you only have to run a primary O2 sensor from the RSX and nothing else and still be able to tune the car. You also get the advantage of lean cut to protect your motor.
This diagram shows what pins need to be removed and then rewired.
I will try to explain this a little.
There are 5 wires ran from the ECU to a 6 pin interlocking connector, like the following:
Below is an image of how the ecu looks with the cover off and the daughter board removed:
This is an image of the board desoldered:
Here is another image with the wires soldered where the pins go just before I resolder the end board back on:
This is just before I installed the ecu. I used a 6 pin molex connector from radioshack:
This is an image of the harness I made to adapt the custom harness to the O2 sensor without cutting the stock connector off the O2 sensor:
Here is how I soldered the crimp pins on the molex connector to insure no conductivity issues:
is there a reason you de-soldered the daughter board to make these connections to the "Primary O2 sensor" portion of the RSX board rather than simply adding the wired needed from underneath as the pins for these connections go completely through the board and can be accessed from either side... I'm trying to come up with a simpler solution so someone can do this conversion easily and without so much risk of damaging their KPRO and/or PRB ECU...
justin just curious but about how long did you need to make your 4 wire adapter harness that went from the ecu/relay to the actual plug on the O2 sensor... I'm making one now and curious how much wire I will need...
