ECU MoTeC M 4 Lambda (adv logging Upgrade a pre requisite)

The MoTeC M4 ECU Wideband Lambda Upgrade allows the use of a single on-board wideband Lambda controller for Bosch LSM sensors. This option is enabled for a free evaluation period of the first 6 hours engine running time when the ECU is first supplied to allow for Engine Calibration and Dyno testing but can be permanently enabled by using this upgrade.

The MC31-326005 Logging Upgrade must be enabled first
