K-Pro Dual Adaptor and 06 S2000

[tsugamiguy]

Hey all,

I bought a 2006 Honda race car.
The previous owner had passed away so I have very little information about the build.
I am having trouble and just recently discovered the K-Pro device under the passenger dashboard.
I am trying to set the car to run off the stock ecu but it will not start. The green key light for the immobilzer does not light up at all I think this may be why the car wont start.
The car will only run when the dual adaptor is used with the kpro piggyback ecu.
When this method is used their are 3 dtc codes.
P2649 VTEC Solenoid valve -
P0135 02 Sensor Heater Circuit Malfunction
P0141 02 Sensor Heater Circuit Malfunction
I replaced all three sensors with known good replacements and still get the trouble codes.
The car will lose all throttle response when run near redline, and will need to be restarted to regain throttle response.
I would like to return to stock ECU and use the FlashPro device I bought last week.

Any help would be greatly appreciated.

Bill

Are you sure that the immobilizer is present in the steering column?
