The guy doing my swap is wanting to know if i have a supra ecu or aristo ecu. And i can't get a hold of the guy that sold the motor to me. But i don't think he would no either.
How can i tell the difference between the 2 to see which one i have?

 

Time is very short for me and im trying to search over my phone since my computer is down, and its very hard. Thanks for any help

 

check the part number on the sticker...post a pic of the ecu and I can help you out

AHH beat me to it staticpage. touché'

 

Can't thank you all enough for the help but thanks. Maybe one day i can return the favor to someone new

 

sorry to dig up an old thread but does anyone know how to tell what a ecu is without the stickers? my comp only has a large yellow sticker with 01 on it?

 

im sure some would appreciate that you actually tried to searched . but sorry I cant help with your question. im sure someone on here can.

 

i have googled, searched every forum pertaining to toyota, lexus and have found NOTHING

 

Look all over the ecu carefully to see if the case is stamped anywhere with numbers.

 

I don't think there is a way other than having a rough idea what it came with and some trial and error based on what codes it is giving. where did you get the ecu or what did it come out of.
if you only know its a 2jz ecu and nothing else not even US or JDM then it will be difficult to figure it out.

 

its a 2jzgte swapped 95 but i dont know what engine it is either looks like some jdm and usdm parts n the engine and i am having issues with hot start and triin to figure out if its the ecu or wth the problem is lol
