Very excellent product working very well with no problems since I installed it thank you very much 😊.

I have a short somewhere in my jeep. I thought it might be the computer, but it wasnt the ECM. I guess I have to backtrack the electrical and find a wire that is probably frayed. But thanks for sending the flashed ECM fast and professionally.

I’ve had the refurbished pcm in my 02 liberty for about a month now. Everything seems to be working as it should now. Bought the unit to get my cooling fan to work again. Would not hesitate to order through flasmasters again.
