Recently we converted our fifth Oreca 03 from the Marelli Ecu to a Motec M190. We make a new internal engine harness that mates with all of the existing wiring harness’s but replaces the engine ecu with a Motec M190. We have developed our own Motec Partner Package to allow full control of the engine and traction control but still retaining the original Megaline gearshift unit. We have also done a second package which allows us to control everything including the gearshift with the M190. So either way we can give you back control of your Oreca 03 engine and traction control.
