A software-managed NāO system with seven independent safety interlocks, your own set points, programmable purge, and a bottle-heater thermostat ā driving its own fail-safe relays, never touching your ECU. Built for the track, framed for off-road.
The controller, live. Every set point ā RPM window, WOT minimum, coolant minimum, purge program, bottle-heater target & cutoff ā right where your thumb is.
Nothing is hard-coded. Dial in the window your engine likes, and the interlocks hold the line.
Set the RPM window the system will arm inside (e.g. 3000ā6500), the WOT / TPS minimum so it only fires at full throttle, and a coolant minimum so it never hits a cold engine. Outside the window, the run solenoid simply can't energize.
Program the purge ā number of bursts, duration each, and the interval between ā to clear the lines and put on a show. The bottle-heater thermostat holds your target bottle temperature with a hard cutoff, so pressure stays in the sweet spot without ever cooking the bottle.
Every one of these has to be true, at the same time, before a single relay clicks. Any one false, and the run solenoid stays dark.
A physical, guarded toggle in the cabin ā hardware-true and independent of any software state.
A deliberate touchscreen arm, separate from the hardware switch. Two hands on the safety.
Read from CAN. Nitrous on an unloaded driveline is an instant over-rev ā so it's blocked in Park or Neutral.
Inside your configured low/high band only. Too low to bog, too high to risk ā your call on the edges.
Throttle at or above your wide-open threshold. No part-throttle surprises.
At or above your minimum temperature. A cold engine never sees a hit.
At or below the heater cutoff, so bottle pressure stays in spec before anything fires.
Purge has its own, separate gate ā it only needs the software arm, because purge vapor never reaches the engine. And every relay is fail-safe default-OFF: lose power, lose a signal, drop a wire ā it closes.
Every part is original parametric SVG ā live values, heater glow, purge vapor, flow particles. Nothing scraped. Drop any of them onto your screen in the Dash Builder.
The dashboard reads your Corvette passively over CAN, then switches its own relays and solenoids to control the kit. Your factory tune is untouched, your warranty intact. No reflash, no CAN injection into safety-critical systems.
| Control method | Pi-driven relays / solenoids ā fail-safe default-OFF. Never writes to the ECU. |
|---|---|
| Engine data | Passive CAN read (RPM, TPS, gear, coolant) + bottle temp (DS18B20). Read-only. |
| Interlocks | Seven independent gates evaluated continuously; any failure latches the run solenoid OFF. |
| Use | Off-road / track use, framed accordingly. Built to order, per car ā we confirm feasibility first. |
Wet or dry, single-stage ā we scope your setup with you before anything ships. We don't claim what we can't put on a real car.
Nitrous Control ships as part of the C7 Dashboard's built-to-order Track build, alongside relay exhaust control, track gauges, and telemetry. Want to see it on a screen first? Lay it out in the Dash Builder.
