Description

The LPC8 is a spark ignition engine management system, presently capable of fully sequential operation (injection and ignition) on engines with up to 8 cylinders. Shares architecture and most features with the LPC4 but has more capabilities. See product's home page for more information.

New generation introduced in January 2021, this includes a new lambda sensor controller circuit, more analog inputs and the possibility of directly attaching two lambda sensors.

You can select optional input amplifier modules for the crank and cam position inputs at order time. These are necessary for some engines equipped with variable reluctance sensors but not all. If your engine has VR sensors and you are unsure, getting the module is the safe bet. If you are unsure what kind of sensors your engine uses, contact us.

This unit has a built in controller for a wide band lambda sensor so we'd suggest also getting the LSU4.9 sensor and connector to complete the package, but are leaving it optional in case you'd like to use a different sensor.

As of January 2021 the controllers are now available with an optional second lambda sensor interface at a slightly increased price to cover the labour of calibrating the second input. Existing units may be returned to get this upgrade performed also.

As of October 2022, the controllers now have dual CAN bus as a standard feature, as well as four added general purpose outputs and dedicated IO for EFI relay control, bringing the total number of connector pins on the controller up to 84 not counting the USB, which is a massive IO count in such a small box. This update also includes revised ignition output circuits to better support ignition coils that need an abnormally high amount of current to trigger their logic level inputs such as the red Audi coils.

As of June 2023, single wide band input is discontinued and all controllers come with dual wide band lambda inputs as standard.
