Hello.
My question is if someone know if there are any differences on the following ecu's:
6gen celica rev3 engine,
- 3SGE JDM spec 94-99
- 3SGE EU spec, 94-95 before EGR was installed
- 3SGE EU spec, 96+ with EGR

Are all ecu using the same part numbers?
And can I use for instance a eu spec ecu on a jdm engine?
I tried toyodiy.com, but I can't find any ecu there.

you'll find the ecu in:

Electrical > Electronic fuel injection system
Computer, engine control.

afaik they have all the same plugs and pin out. but the +EGR probably has an additional wire

JDM ecu will have speed cut at 180km/h, not 100% sure the EU have it

Thanks! Finally I found what I was looking for.
EU does not have 180km/h cut.
The JDM ecu have different part number than the euro spec (non egr), but as far as I know the JDM 3sge has slighly higher compression ratio, so it produces 178HP,
while the EU spec (non egr) produce 175 or 173.
Wonder if the JDM engine would run well on a eu spec ecu...
