hey guys i picked up a 00 gsr 4 banger from friend who retrieved it back from theft. it has a p73 type r square ecu and i want to put the original ecu. so doing some shopping i came across a couple ecu's all obd2b but some are rectangle and some are square. I wanted to know..

did usdm ever come with square ecu?

how do i tell if its a usdm ecu?

thanks but did 00-01 iintegra come in square or rectangle? even though the last three digit of my ecu confirms its usdm

 

00-01 gsr usdm ecu is square, just buy mine.
