Please give me direction on what needs to be done to convert from the '06+ S2k K-Pro dual system to a simple FlashPro system.

1. Do I need to retune or can I reuse the same map?
2. How do I return the unit to you and purchase the difference?
3. Is there anything else to consider that I may be missing?

You cannot use the same calibration, as it is for a K-Pro. You would have to start your tuning from scratch.

We do not offer an upgrade for this. You would have to Either just keep the dual setup yourself, or you could try to sell it as a complete kit and you would also have to sell the reflashed EOM ecu with it so the other person can get their key and immobilizer matched to it. You would then need to either purchase a new ECU or trade ECUs with the person and get the immobilizer matched.

Please clarify which ECU's were modified. Is the OEM s2k ecu just reflashed or is the board somehow changed? Is the RSX ecu reflashed or is the board modified?

Also, for the FlashPro does the original s2k primary o2 sensor need to go back on (the dual is using the RSX o2 sensor)

The OEM ECU is reflashed (will not work properly by itself), and the RSX ECU is modified specifically for use with a dual adapter setup and will not work in other aplications.

To use the FashPro you must use the OEM s2k O2 sensor.

Can the RSX PRB ECU be used in any other application after being a dual setup?

I.E. Can I send this back to you to modify for RSX KPRO or 00-05 S2k KPRO use for the $350/$450 you have listed?

No, It can only be used in a dual adapter setup.

I had a question to the flipside of this question since I recently picked up the same setup. What about sending in a separate PRB ECU along with the dual-adapter setup. Or is the Hondata chip modified in a way as well to make that impossible?

I have the conversion harness and 06+ dual Kpro. I was told by one of your distributors (whom I purchased this setup from USED) who said that upgrade was possible only to receive a different answer through e-mail from Hondata several hundred dollars later. :(

(to OP, sorry to threadjack lol)

You would be much better off selling what you have to someone that can use it and just purchase a brand new K-Pro for the virgin PRB.
