94 GS300 ecu in an 93 SC300
 

Ok so ive searched and read and found that an ecu out of an obd1 gs300 would work in an obd1 auto sc300 right? Well I pulled a known working one from a 94 gs and put it into my 93 sc300 and nothing...car wont start, but the ecu powered the gs prior to it being wrecked. Am I missing something? What Gives?

There's more to it than just swapping the ECU. Just because the Engine & ECU come from a 2JZ doesn't mean that they will work in an SC. The pin configuration is most likely different.

Ah...searches, and google all led me to believe it was the same and should work. This should be a psa as sc ecu's die frequently
