My 2003 civic LX needs a new ECU/PCM. The dealer is asking $1000, and I'd much rather buy a used ECU and have them install it.

The problem is, the dealer says the part number is 37820-PLM-426...

...but all of the used ECUs I'm finding are 37820-PLM-L56 or L52 or L54.

Does it make a difference what the last 3 digits are? The mechanic at the dealer says everything needs to match exactly, but I'm not sure if he's just trying to get me to buy his part. Thanks for any help you can give!

Have you tried your local junk yard ,find one that has been in an accident that best matches your Honda as far as year model and same motor pull computer and try to see if # match

Price should run no higher than 100 dollars at least that's what they'd go for here in the Miami

Used? Try
www.car-part.com
Used unit will still have to be programmed before the engine will run.

Tell that dealer to suck a nut because he's blatantly trying to rip you off. Use car-part.com like they said and find a new dealer. Dont give buisness to dishonest ****s

x2, car-part.com is a great website for used parts

Thanks, guys. I posted this on the other thread, but that guy at the dealer was definitely trippin'. He lied to me about the part number, and when I went to see the part from my car myself, it definitely was something I can get used off of car-part.com. I just can't believe they would straight up lie to me about the part number. Whatever happened to trying to help people?

If I replace the ignition that came with the used ECU would you still need to re program?

No.
A matched set should work without programming.
