Default 1999 Accord ECU

Hi,

I need to replace the ECU on my 1999 Honda Accord EX 4Cyl. The local Honda dealer suggested 37820-PAA-L50 as the part number.

I'm looking for a used ECU coz the new one costs like a million bucks [sm=icon_flaming.gif]. I've found couple of ECUs on eBay with 37820-PAA-L61 and L60 part numbers. And the sellers claim it will definitely fit my car.

Can you please confirm if I can use 37820-PAA-L60 or L61 on my car.

Thanks in advance

Your best bet is to go to the junk/salvage yard or use car-part.com and have them find a used one for you. That's what I did, only cost me $85. But, those part numbers should be interchangeable, the part you really care about is the PAA part, Honda ECUs have a PXX numbering system.

They do, but I don't think the chip data is stored in the ECU... I know the transponder/reader thing is around the ignition cylinder... good point to bring up with the Honda dealer.

interesting, so your saying you took a ECU from the junkyard and put it in your accord? cause with ludes that cant be done without taking the ignition system with it.

Nope, not on this Accord. I did on my 95 though. I'm not at all sure, so I'd ask the dealer before I spent any money.

My (former) 98 Accord EX DID have an immobilizer. I dont have the Helm book (wiring drawings) any more, but Im pretty sure its in the ECU (PCM actually).

If you get a key from the donor car, I think theres a way to make it work by adding your keys. But I dont know the details of how to do that...

There is no reason to pay that kind of price if you just want your car to start. The process of eliminating the immobilizer is not hard (just need your ECM computer). Send me a personal message if you are interested in the service. Why pay honda all that money.
dude... back off...
mods! please block this guy!!!!
