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.

ECU units, including our engine control modules for sale, are year and transmission specific. You can use automatic transmission ECU’s in manual transmission cars, but not the other way around. California ECU’s 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 ECU’s. 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 ECU’s around 2001-2003 also had issues with transmission shifting. We can take care of these as well.
