RallyComm is a rally-grade crew communicator for the Can-Am Maverick R and any AiM MXm-equipped race car. Three models — Cockpit K8, Cockpit PKP, and headless Recon. WiFi is the primary path; 4G LTE is an optional failover add-on.
RallyComm is built around a single principle: keep the driver heads-up, and keep the crew informed. Everything the crew sends lands on the dash the driver is already watching. Everything the crew asks — "what's fuel?", "what's oil temp?" — comes back as an auto-reply with real CAN-bus telemetry.
Inbound SMS renders on your existing AiM MXm as classified alarms — SOS, URGENT, WARN, INFO — with sender name, action code, and color. No additional screen needed.
Twilio SMS backbone + Zello Channel PTT. Driver replies with a single keypad press; crew sees delivery confirmation in seconds. Text and voice on the same device.
Piper TTS speaks every inbound message over your intercom. Driver never takes eyes off the road to read — the message plays automatically, prioritized by urgency.
Eight programmable RGB keys. Cockpit K8 ships with AiM K8 Open by default; Cockpit PKP uses Blink Marine PKP-2400-SI (CANopen). Runtime config switch — no firmware rebuild. Recon ships without a keypad.
2.4 GHz WiFi is the primary link — service park router, driver's phone hotspot, or chase-car uplink. Add the SIM7600G-H global LTE modem at checkout (+$100 on Cockpit, +$120 on Recon) for cellular failover on stage. Bluetooth 5.0 standard for driver headset / tether.
Native socketCAN, two isolated buses: 1 Mbit/s keypad on can0, 500 kbit/s AiM bus on can1. Publishes alerts to the dash and reads telemetry from the ECU — a full gateway, not just a transmitter.
Inbound messages are parsed for keywords — pit, flat, fuel, mech, sos — and mapped to a 3-byte enum the dash can render without reading a single character of text.
Hidden brain box mounts behind the dash or under the seat. Single Binder 712 cable to the keypad. Power via a fused tap on the vehicle's 12 V rail — TVS-protected against alternator transients.
One firmware image, two supported keypads, three models. Updates roll out over WiFi or cellular. Swap keypads in the pit by editing one line of config and rebooting — no flashing, no builds, no bricks.
Text the car. Get the answer. Send ?fuel, ?oil, ?rpm, ?loc, ?status — RallyComm reads the CAN bus and auto-replies with live values. The standout feature of the headless Recon model; available on every model.
Every inbound message follows the same four-step pipeline. Every path is observable in the RallyComm web UI, and every classification is deterministic — no LLM in the loop, no surprises on stage.
Twilio receives the message from the crew chief's phone and webhooks RallyComm. No app install on the crew side — plain SMS from any phone.
RallyComm parses the body for keywords and maps it to (sender, category, code). Truncation and unknown-sender flags are set automatically.
The 3-byte alert frame hits CAN ID 0x303 on the AiM bus. RaceStudio 3 alarms on the MXm trigger on the rising edge of RC_SMS_Seq.
Piper TTS reads the full message over the intercom, the web UI logs it, and the keypad's reply key pre-arms with a suggested response.
Pick the cockpit model that matches your keypad preference, or go headless with Recon when you already have a dash and just want the crew-to-car link. WiFi is standard on every model; cellular is an optional failover add-on.
No keypad. No dash dependency. Just a brain box that bridges SMS, Zello, and CAN — so the crew can query the car and the car can answer back.
Dash alerts, voice readout, and a physical keypad for single-press replies. Ships with the AiM K8 Open — proven in the AiM racing ecosystem.
Same as Cockpit K8 but with the Blink Marine PKP-2400-SI. CANopen CiA 301 + 401 — industrial standard, marine-grade, M12 connector.
The Cockpit K8 and Cockpit PKP editions differ only in the keypad. RallyComm ships with a runtime keypad driver abstraction — choose AiM for racing ecosystem compatibility, or Blink Marine for CANopen standardization and marine-grade ruggedness. Swap anytime by editing one line of config.
8 RGB keys · AiM proprietary CAN · 1 Mbit/s

Runtime switch, not build-time. Edit config.keypad.driver, reboot, done. One firmware image supports both — spare keypads are drop-in replacements even if they're a different brand. Recon units ship with config.keypad.driver = none; add a keypad later and flip the flag to become a Cockpit-class unit.
Every byte accounted for. Every pin documented. RaceStudio 3 channel tables and an installer guide ship with each unit; request the full integration packet at any time.
Every model ships with WiFi. Add 4G LTE at checkout when you want cellular failover on stage. Hardware, pre-configured firmware, documentation, and 12 months of updates included in every SKU.
SMS-on-demand telemetry. No keypad. Smallest footprint, lowest price.
In-car keypad for single-press replies. Dash alerts on MXm. Proven AiM ecosystem.
Blink Marine PKP-2400-SI. Industrial-standard, marine-grade, M12 connector.
Yes. Anything with an AiM MXm / MX Strada / MXS dash is supported out of the box — you'll load the provided RaceStudio 3 project or merge the custom channels into yours. Non-AiM dashes can still be used if they expose custom CAN channels; contact us for a compatibility check before ordering.
No — cellular is optional on every model. WiFi is the primary link: you can use a chase-car hotspot, a service-park router, or even the co-driver's phone tethered to RallyComm. Twilio still handles the SMS; RallyComm just gets to the internet over WiFi. If you want on-stage cellular failover (remote areas, long liaison sections), add the LTE module at checkout for $120 or upgrade later with a $149 self-install kit.
Recon is the headless comms gateway — no keypad, no cockpit hardware, just a brain box in the vehicle. The killer feature is SMS-on-demand telemetry: the crew texts ?fuel, ?oil, ?rpm, ?loc, or ?status to the car, and RallyComm reads the vehicle CAN bus and auto-replies with live values. Perfect for teams who already run a dash, or for support / chase cars, course cars, and overlanders. Recon still publishes inbound SMS to the MXm if one is connected, and still speaks messages via Zello.
Yes. The Cockpit upgrade kit ships with the keypad of your choice, a second MCP2518FD CAN HAT, the cockpit-side harness, and a pre-written config snippet. Self-install in about an hour, or send it to our shop. $899 for the K8 kit, $949 for the PKP kit. Once installed, edit one config line (keypad.driver = aim_k8 or blink_pkp) and reboot — same firmware, same OTA, same everything.
Yes. The LTE upgrade kit is a SIM7600G-H HAT that stacks onto the existing SPI bus, plus cellular antennas and a device-tree overlay update. $149 self-install, or $49 labor at our shop. Works on any Recon or Cockpit.
Twilio SMS is $0.008 per message in the US — a typical two-day rally with 200 messages costs under $5 in message fees. Zello PTT is free on the community tier, $6/user/month on Business. If you add the optional LTE module, a data SIM runs $5–15/month depending on carrier (1 GB/month is plenty). WiFi-only teams pay $0 in connectivity — they rely on service-park routers and chase-car hotspots.
No. The crew texts from any phone to the car's Twilio number. For PTT voice, the crew uses Zello (free app, iOS/Android). The driver never touches a phone.
Tap into your vehicle's switched 12 V rail through the provided fused harness. RallyComm accepts 6–20 V DC and is TVS-protected against alternator load dumps. Draw is 2.5 W idle, 5 W peak.
No. You own the device and its firmware. Ongoing costs are your own SIM + Twilio + Zello (if you use their Business tier). Firmware updates are free for 12 months and $49/year thereafter.
The hardware is general-purpose. Overlanders, expedition trucks, off-grid crew logistics, and industrial vehicles with CAN-based dashes are all plausible use cases. Contact us if you have a non-racing application — we'd love to see it.
RallyComm ships with a fully assembled, pre-configured firmware image under commercial license — pre-trained TTS voice, RaceStudio 3 project files, classifier, CAN gateway, web UI, and OTA client included. We publish our custom CAN channel table and RaceStudio 3 integration recipe so teams can verify compatibility and do their own alarm wiring. Customers who want deeper access can contact us about a developer license.
We're taking pre-orders for the first production run. Tell us which model (Recon, Cockpit K8, Cockpit PKP), whether you want LTE, and your vehicle + dash model — we'll send back a compatibility confirmation and a secure payment link.
