Automobile Computer Solutions (ACS) was absolutely wonderful to work with and provided first-class service. My main work truck went down due to a faulty ECM. After dealing with another ECM repair company for over a week and a half, I reached out to ACS. I received the ECM on the 3rd business day from the time the order was placed, installed the new unit, and it worked flawlessly. Absolute wonderful service, product, and price. I recommend ACS to anyone!
