We stock fully rebuilt Lexus SC300 and SC400 ECU’s from 1992 to 1996. All refurbished ECU units are tested in our on-site vehicles to ensure 100% functionality with no error codes. This ensures that you will receive a perfectly working plug-and-play ECU.

These replacement ECU units, including our engine control modules for sale, are year and transmission-specific. You can use automatic transmission ECUs in manual transmission cars, but not the other way around. California ECUs will work fine in a federal emissions vehicle, but you will have a check engine light for CA specific emissions equipment. Year splits also exist with federal emissions vehicles and sub-O2 sensors. 1992 and 1993 do not have these while late model 1994+ do.

All of these factors are important to consider and stress the importance of matching up your exact part number to ensure 100% compatibility.

We also carry Toyota T100 ECUs. Those part numbers are as follows:
1996-1997 2.7L 4 cylinder A/T 2WD: 89661-34190
1997 3.4L V6 A/T 2WD: 89661-0W040
1995-1996 3.4L V6 A/T 2WD: 89661-34250
1998 3.4L V6 A/T 4X4: 89661-0W062

Toyota RAV4 ECUs around 2001-2003 also had issues with transmission shifting. We can take care of these as well.
