Firmware Update Nexus V1.24.1 and Elite V3.10.1 – October 2023

New firmware versions are available for the Elite and Nexus range of ECUs, for all the juicy details please check out the full release notes available within the NSP software, however, we wanted to share a few of the highlights with you.

The big one is the new MAP prediction and Fuel film model under Fuel Tuning. This is a new alternative to the Transient Throttle function and is used to smooth out any hesitation or “flat spots” when rolling on the throttle. Our beta testers have been raving about this new function, some even said the words, “It’s the best update ever, it’s like a new ECU!” – So be sure to check that out.

Another favourite new feature is the addition of “Exhaust Cutout”, “Nitrous Bottle Opener” and “Generic Open Loop Motor Controller” functions. These allow a DC motor to easily open or close a valve without position feedback, for use in such situations as – you guessed it, a Varex-style exhaust cutout, or operating a Nitrous Bottle Valve.

There have also been improvements to Cruise Control behaviour, Line Pressure Control and Per-cylinder Knock Control (That one is NEXUS only, sorry Elite guys).

We’ve also added trigger patterns for:

• Mini – Classic EFI – Rover Mode1 Flywheel Crank
• Rover – K Non-VVC Late with Home

And Vehicle CAN options for:

• Subaru WRX MY17
• Nissan Navara D40 2012

You’ll need to be running NSP version 1.34.0 or newer to upgrade your Haltech units to this new firmware, so make sure you’re up to date there first.
