We make it talk to the devices you actually have.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGeneric CAN (GCAN) is the free firmware feature that lets an eligible Haltech Nexus ECU, iC-7 or uC-10 send and receive custom CAN messages. What it does not do is decode your vehicle or your third-party hardware for you. Frame IDs, byte layouts, scaling, endianness, update rates and bus timing all have to be defined by hand in NSP, and one wrong byte means a dead cluster or a dash showing garbage. The \u003cstrong\u003eHaltech GCAN Mapping Service\u003c\/strong\u003e is a remote session where a Tuned By Shawn technician builds that configuration for you, loads it into your map and verifies every signal live while you watch. You supply the device documentation or a DBC file, we supply the working CAN setup. Delivered over Zoom with screen share, so you keep the car in your garage and walk away with a config you can read, edit and reuse.\u003c\/p\u003e\n\u003ch3\u003eWhat We Map\u003c\/h3\u003e\n\u003cp\u003eGCAN is built for the devices that were never on Haltech's pre-built support list.

The form asks for your ECU or dash model, current firmware, the device or module you want to talk to, and any documentation you have for it: a CAN protocol sheet from the manufacturer, a DBC file, or a log capture. The more complete the documentation, the faster the session. For OEM modules where no public protocol exists, let us know in advance so we can confirm whether the messages are already known to us or will need reverse engineering, which is quoted separately.\u003c\/p\u003e\n\u003cp\u003eBefore the session, your Nexus ECU or display needs to be on GCAN-capable firmware (V1.36 or later for ECUs, V2.36 or later for dashes) through NSP 1.48 or later with beta opt-in enabled. If you are not there yet, we cover the update at the start of the call. You will need a Windows laptop with NSP installed, a USB-C connection to the unit, key-on power for displays, and the CAN device physically wired to the correct bus with termination in place. Physical wiring is not included in this service; if you need the harness side handled, see our wiring services.\u003c\/p\u003e\n\u003cp\u003eThis service is priced as a single session covering one CAN device or module. Multi-device builds, full factory cluster integrations on unsupported chassis, and reverse engineering of undocumented OEM traffic are scoped and quoted after the intake form. Unused session time can be applied to base tuning at our hourly rate.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x remote GCAN mapping session over Zoom, one CAN device or module\u003c\/li\u003e\n\u003cli\u003ePre-session intake and documentation review\u003c\/li\u003e\n\u003cli\u003eFirmware and NSP version check, GCAN enable on the correct bus\u003c\/li\u003e\n\u003cli\u003eTransmit and receive frame configuration in your NSP map\u003c\/li\u003e\n\u003cli\u003eLive verification of every mapped signal\u003c\/li\u003e\n\u003cli\u003eMap backup before and after, saved to your machine\u003c\/li\u003e\n\u003cli\u003eWritten frame and signal summary emailed after the session\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eUniversal:\u003c\/strong\u003e Any vehicle or engine running an eligible Haltech Nexus ECU or standalone Haltech display.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSupported hardware:\u003c\/strong\u003e Nexus T1, T2, S2, S3, R3, R5, all Nexus Plug-in ECUs, iC-7 and uC-10 displays.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNot supported:\u003c\/strong\u003e Haltech Elite range (no GCAN capability) and Nexus Rebel (pre-built vehicle CAN profiles only, no custom frames).
