Hondata KPro V4 (00-05 S2000)

This is a specially adapted ECU which allows the 2000-2005 S2000 to run the RSX Type S ECU (PRB). The Hondata KPro V4 Upgrade for the Honda S2000 is the perfect solution for customers that want an easier to manage tuning solution. Please note that this product is only for the upgrade to the KPro V4 on the customer's PRB ECU. Hybrid Racing does not supply PRB ECU for this KPro option. In order to use the PRB ECU, the engine crank and cam sensors must be changed to equivalent 2006-2007 parts - see below.
The S2000 KPro includes a user-supplied RSX (PRB) ECU adapted for the S2000 and a wiring harness for the crank and cam sensors. It does not include the Honda parts—see mechanical modifications below. All user-supplied ECUs must be PRB A01-A12 and in perfect working order. Hondata will not use any other ECUs for the S2000.

There are two options for this specific KPro. You can either provide your own PRB ECU and have it converted to the proper KPro for your S2000 or you can provide a PRB ECU with KPro for an 02-04 K Series installed on it already and have this upgraded to the S2000 spec. Hybrid Racing does not provide an ECU for either of these options, so please plan accordingly. 

Warning
Within the USA this product is legal only for racing vehicles which may never be used upon a public highway.

Mechanical ModificationsThe following items must be replaced before the S2000 K-Pro can be used. These parts are not supplied by Hondata and should be purchased from a Honda dealer.
Crank sensor 37500-PZX-003
Crank wheel 13622-PCX-013
TDC sensor 37510-PZX-003
TDC wheel 14112-PCX-003
Valve cover 12310-PCX-020
Drain plug washer (for PCV valve) 94109-14000
PCV valve 17130-PCX-003
IAT sensor 37880-P05-A00 (not required, but stock IAT will read about 30 degrees hotter)

The approximate cost of these parts is $300-375.

Immobilizer. The S2000 immobilizer is not supported.
Water Temperature. The S2000 dash water temperature display functions as per normal. For an AP1 the second segment normally lights at 145 degrees F, and the third at 165 degrees F.
Air Conditioning. In KManager you will need to select 'Use alternate AC switch input'. No wiring changes need to be made. Idle up and enrichment is as per the stock ECU.
Closed loop.  The RSX ECU will run in closed loop using the S2000 primary oxygen sensor. Due to the RSX ECU normally using a wide band oxygen sensor, in KManager you use select 'Use Secondary Oxygen Sensor for Primary' (don't panic - the ECU is actually running off the S2000 primary oxygen sensor, which has been routed through the RSX ECU as the secondary oxygen sensor).  Using a wideband RSX oxygen sensor is not recommended because the oxygen sensor is expensive (as much as an aftermarket wideband) and substantial re-wiring is required. The ECU can datalog aftermarket wideband controller which output a analog voltage (via the ELD input).KManager ConfigurationThe following parameters should be used in KManager:
Use only PRA ECU calibrations (PRA ECUs are the only ECUs which support a narrowband primary oxygen sensor).
Disable the immobilizer.
Disable VTC.Disable the multiplexer.
Select 'Use alternate AC switch input'.
Select 'Use Secondary Oxygen Sensor for Primary'.

OBDII Scan tools.  OBDII scan tools work normally.
User Supplied ECUs. User supplied ECUs must be checked before sending to Hondata. Any damaged or faulty ECUs will incur a processing cost.
ECU Mounting. The ECU is the approximate size and shape of the S2000 ECU, and is located with the same orientation as the S2000 ECU, however it does not have the mounting holes in the same location. A mounting bracket is supplied to mount the ECU in the stock location. Note that this photo is from a hand made prototype - the finished bracket will be laser cut.
