whats the difference between ecu from the sc300
\/
ecu1 part# 89661-24311 vs ecu2 part# 89661-24312

im looking for a replacement from my current ecu ending in 24312. just wondering if i buy an ecu with part# ending in 24311 would there be an issue?

 

what year is your sc300?

there could be some minor differences. such as, the 92-94 sc's have a kick down switch under the accelerator pedal for the transmission where as the 95+ have a computer controlled kick down

or the 24311 is a cali spec ecu that has 4-wire O2 sesnors as well as a third O2 in the cat

it may work but its best to find the exact part number your pulling out

 

i have a 93. my ecu is fed and Canada emission... they had one for sale on ebay but i missed that..

i need one... the transmission isn't shifting, have to shift manually, gear by gear, and the engine is consuming fuel alot... im in desprate need of an ecu.. but when i connected another ecu. it changed the car lol. it started to shift like a should, idling like it should, working

ecu ending # 24311 found one ebay for 59.99 in perfect working condition with warranty. its tempting
