I think I need a ECM

I jut bought HP Tuners and I can't write to my car it says invalid vin/os. It was tuned by a local guy for stand alone with tuner cats. I'm guessing I need a reflash with a tech 2 or get another ecm. What ecms are capable of running the 24x dbc LS engines? Will the 4 cyl computers work? The local JY has lots of 00-04 gm vehicles.

It can be fixed with tuner cats or efi live if you dont want to get another pcm. If you want a another pcm look for the last three digits of the service number 896 or 411. Either one of those will work for you. I can probably fix it cheaper than you can get another pcm for. PM if you're interested.
