It is now possible to run the popular Hondata Kpro V4 on the 2000-2005 Honda S2000 without any modification or sensor conversion. The original Hondata Kpro S2000 ECUs require the conversion to 2006+ Valve cover, Cam and Crank Sensors and pick up wheels, which is also specific to only S2000 F20c/F22c engines. This solution is now applicable for S2000 engines. This new unit simply plugs into the stock engine harness, standard Hondata Kpro and you're ready to tune. OBD2 ready
