Before you update
V2.34.0 needs NSP 1.46.3 or newer. Update NSP on your laptop first, then load the dash firmware. If NSP's updater isn't offering new versions, check your computer against our note on NSP updater TLS requirements.
New feature
- Every dash now has an Oil Over Temperature channel, so you can build an oil temperature warning straight from it.
Haltech CAN: more channels, better scaling
If your dash reads from a Haltech ECU, these are the changes you'll notice:
- Oil Level and Clutch Pressure can now be displayed.
- The four Nitrous Enable output states (1 to 4) are now available, along with NOS Bottle Opener State and Exhaust Cutout State.
- Turbo Speed 1 and 2 now show the correct values, after a scaling error was fixed.
- Specific Humidity scaling is corrected too.
Third-party ECUs and OBD-II
- With an ECUMaster ECU, the gear readout is now right.
- On OBD-II, Ambient Air Temperature reads correctly, and channels the car doesn't support are handled more gracefully.
Running a non-Haltech ECU? See OBD-II channels supported by Haltech dashes and sourcing data for dashes in NSP.
Display and NSP fixes
| Area | What changed |
|---|---|
| Tables | On an axis set to Discrete Centered with consecutive whole-number values, lookups no longer round to the wrong cell |
| Battery light output | Its channel state now reads On or Off |
| PWM-capable outputs used as switched outputs | Only the pin state is shown now |
| Transmission oil temperature switch | Its input state now reads Ok or Over Temp |
| On-board logging | You now get a warning if a logging group has channels in it but is switched off |
| Fuel level sensor | The Input Type setting is no longer ignored |
| Error states | The dash shows an error message rather than a huge negative number |
| NSP navigation tree | External devices that are connected but not enabled in the Haltech CAN System menu no longer flicker |
| Peak Values | Now found under Functions, with its own enable setting for the input |
| Device timeout | Dash to ECU timeout messages are fixed |
| Haltech CAN System | Choosing it now turns on Enable External IO Control by default |
Should you update?
If you use any of the newly supported channels, run an ECUMaster ECU, rely on OBD-II data, or have seen odd turbo speed readings, yes. Otherwise it's a sensible update to do next time the car is plugged in. Save a copy of your dash layout before you flash anything. For how the dash and ECU share inputs and outputs, see IO between dash and ECU in NSP, and for ECU firmware changes, check the Nexus ECU release notes, such as V1.34.3.
