I should have read the reviews prior to placing an order. Suffice to say I was taken by this outfit. I have been waiting for 2 months and thousands of attempts to contact them by phone and email with ZERO response. Same issue other reviews had. They call you back and tell you your ECM is unprogrammable, fooled me into purchasing a fully guaranteed replacement with lifetime warranty, then went completely dark... Expensive lesson learned. Will attempt to pursue legal action, but probably won't be worth time and effort. STAY AWAY from these jokers!
