Several options are available as upgrades to customise and grow your system. These additional features are activated through a simple password system, at any time when you need it.
For the M84 engine management system the following upgrades are available:
Dual Wideband Lambda
Single on-board Wideband Lambda is included as standard, with a dual option available as an upgrade for applications that require more than one Lambda input.
- Traction Control and Launch Control (2, 3 or 4 wheel)
- Hi/Lo Injection (secondary injection)
- Gear Change Ignition Cut (flat shifts)
- Overrun Boost Enhancement (anti-lag)
Traction Control ‡
The Traction Control option enables user-programmable Traction and Launch Control. Traction Control reduces engine power, by cutting cylinders, to limit wheel spin when traction is broken.
Hi/Lo Injection ‡
Hi/Lo injection enables control of primary and secondary sets of injectors. The injectors are controlled using a 3D table to define the balance of fuel flow between primary and secondary injectors.
Gear Change Ignition Cut ‡
Gear Change Ignition Cut (also known as ‘flat shift’) momentarily cuts engine power to allow a gear up-shift at wide open throttle. An input to the ECU is used to trigger the cut.
Overrun Boost Enhancement ‡
Enables boost control to reduce turbo lag and improve throttle response in tight and twisty stages for turbocharged cars, specifically in rally events.
‡ Traction Control, Hi/Lo Injection, Gear Change Ignition Cut and Overrun Boost Enhancement are available separately or as part of Advanced Functions.
