RB26DETT, RB25DET, and RB20DET engines in the R32, R33, and R34 Skyline platforms offer tremendous tuning potential, but the factory ECU often limits what you can safely achieve. The Haltech Elite 2500 + Plug'n'Play Adaptor Harness Kit is a complete engine management solution that plugs directly into the factory harness, eliminating the need for complex rewiring while giving you full control over your engine’s performance. This kit includes the Elite 2500 ECU with drive-by-wire and race functions, the Plug'n'Play adaptor harness, M14 x 1.5 air temp sensor, auxiliary I/O harness, USB programming cable, and software key — everything needed for a straightforward upgrade on manual transmission models.
The Elite 2500 supports a wide range of OEM functionality, including boost control, idle control, A/C output, thermofan, tachometer, fuel pump control, knock sensors, and more. It features advanced tuning capabilities such as 32x32 mapping, real-time programming, closed-loop O2 control, dual channel knock control, variable cam control, and on-board data logging. Flex fuel support, wideband auto-tuning, and OBD II code storing make it ideal for both street and competition builds. The system is compatible with Windows operating systems and offers USB and CAN communication for seamless integration with modern tuning software and Haltech dashes.
