Part works great and at it fair price
This was broken –
It was broken we paid 180.00 to have it programmed and lost that money

I never opened the package. Ordered wrong item. Look great.. packaged very well.
Tony –
OEM part fixed the problem mine was causing. Had to have dealer program it but was way cheaper than buying it from the dealer. Super easy to change out too. Do it yourself and save a ton of money vs the dealer
Amazon Customer –

Amazon had the best price I could find on a genuine AC DELCO ECM. Shipping was fast, only took two days. I brought my truck and this part to my local GM dealer and they programmed it no problem.

Product is the same you would get at an auto parts store but for way less. No issues at all.

Trabaja perfectamente para un Camaro ss 2010. Solo tienen que llevarla a un profesional para su programación.
