I need guidance on purchasing a new PCM for 2000 corvette.

[Cerry]

I need to replace the PCM on my 2000 Corvette. Here are the numbers from the current PCM:

SERV.NO. 09354896 CYUB
*86CYUB910052Z3LJ* 09381561
HDW NO. 16220610

I need some guidance on purchasing the replacement. I am hoping to avoid going to the dealership.

What do the letters CYUB indicate?

What do *86CYUB910052Z3LJ* and 09381561 indicate?

Is a replacement that is “flash” programmed to my VIN number acceptable?

Why do some programmers ask for only the VIN number and others want my mileage, too?

Wouldn’t a remanufactured PCM be preferable to a used PCM? (I haven’t been able to find a new PCM that the seller programs.)

Which brand of PCM (AC Delco, Cardone, etc.) is the best?

Can anyone suggest a reputable seller of PCM’s for my corvette?

Thanks for the help!

Flashing your VIN will make sure it is programmed as manual or automatic and rear end ratios are correct. Of course if they have been changed then the programmer can modify it.

No need to know your mileage since that is stored in the IPC.

Remanufactured or used are fine. A reman only fixes what is wrong.

Many possible sources. I got a spare PCM and BCM from NAPA. Try Marc at VetteNuts.net for used.

Mr. Sam,

Thanks for your post. Unfortunately neither NAPA or VetteNuts had a PCM for my corvette. However, your information helped me decide on a used PCM. It arrived, I installed it, and it works great! Thank you again for your help.

Great to hear. Did you do the PCM BCM "handshake" procedure?
