It seems that Motec is addressing the 1UZ-FE engine specifically with the introduction of their MLS system. I have contacted Motec and it is the M4 system detuned of some advanced functions in order to offer a more economical package. In addition to the MLS you must purchase the wire harness made for the engine. I think this is a great product and it has been set up on a couple of engines already with great results. I am definitely partial to this system as Motec is a great contributor to the Lexus community.

Here is a quote taken directly from an email that was sent to me from Motec USA: "The MLS is an M4 that has been specifically limited to work with a small engine family at a reduced cost. A Motec M4 will do exactly what the MLS will do plus additionally it can support other trigger system configurations. "

I was also told that the M4 owners manual is availible for download and can by used for reference for the MLS system. Here is a link to their website
