SP Engineering has been testing the HKS F-CON V Pro fuel management computer system with the R35 GTR. HKS does not have a wire harness at this time so we custom made one ourselves. Our current modifications include: HKS GT570 kit, HKS Legamax exhaust, Greddy intercoolers, HKS Premium Suction Pipe Kit, 800 CC Denso Injectors, and SARD FPR.

We have tuned the vehicle and have accomplished good results by only controlling the fuel. A/F is currently at 11.4 at WOT. More testing/tuning are scheduled this coming week as we have plans to play with the ignition/timing to create more power.





We will keep you all posted as more updates come!

Any questions please let me know.
