matching up the right ecu
hey guys, i had the ecu go bad on my 92 sc300. i have an extra ecu but i think i may not be able to use it because since putting it in i cant get the car to time right and it idles really low. i have my old ecu with me now but the numbers are worn off badly and all i can make out is what looks like *9661-24300. when looking at a replacement ecu is there a way to tell which one will work with my car based on the number? also im considering just having this one re soldered. ill try to get the number off the other ecu i have as soon as i can. thanks

The ecu for at/mt does not matter for your year. You can use 92-94, 95 has heated O2's and will give a CEL for wiring problem with O2's. I believe all 96 and up are cali emissions and differ both with OBD2 cat monitoring as well as being OBD2, not your car. Yours is an early ecu OBD1. I have the same one. My origonal ecu had a cap leak on the board and shorted the injector driver. I replaced it with a 93 auto 2jzge ecu. No problems. I love how "dumb" the older toyota ecu's are.
