Anyone know if the 2000 ECU is the same as the 2005 model? Can I get a 2005 ECU and do a simple swap in my 2000? Thanks.
2000 ECU same as 2005?

Is it the same p/n? Then.. yes. It's possible the 2005 may have some updates, and then that would be good news but if it's the same p/n, I wouldn't worry about it.

Part numbers.
I'm sure "LarryB" will know but if you can't find out go to "NSXCB" and ask
"kzukNA1", Kaz, he worked on the development tean in J A Pan on the NSX program and he knows all the model changes by code numbers i've never seen before. He has posted some info on that subject and there're several generations of ECU through out the years and he knows!
Tell him "nigel" told you to ask him.
Also, the last three digits in a Honda p/n designate changes, (modifications) to a particular part. It may have the same first five numbers in the p/n but the last three will let you know if there has been any modifications to the original part. Obviously the centre three, "SLO" designate "NSX".
Cheers

just go to yahoo and do a search for acura parts online delray and you will find delray acura's online website. from there you can look up any nsx part number for any year you want. i am 70% sure you will find that they are different part numbers as the 05 nsx was low emission (LEV) and i don't belive the 2000's were (i thought that change ocurred in 01. but it might have happend in 2000. (the change included air injection, air pump, different cats and exhaust)
isn't there a 'hearsay' that ulev models make 5-10hp as they run leaner? so far i only know about the cats heating up faster.
I am pretty sure 00-05 are all LEV, however according to the part number, 05 ECU is different from 00.

i would not even try swapping them if they are different part numbers. Different part numbers mean that the parts ARE different. it could be something major or as minor as the same ecu with different software based on the weight differences (distribution) of an 05 car (revised styling) versus an 00 car (heaver pop up headlights). think this is trivial, it is not, the nsx has drive by wire throutle and how it reacts when you step off the gas is part of the ecu tune for the car and the off throttle response WAS changed over the years (just one example). OR the change in part number could be major and it wont even start your car. either way, why chance or experiment , get the right part.
Not that this helps you specificly:redface: but the bee as a data point , currently I have my 96 ecu/wiring harness running a 00 3.2 liter motor.No cels(thanks Larry B):biggrin: We just removed the ulev air tubes/piping.I have not dynoed this setup but to my butometer feels fine.So the ecu is pretty tractable.
