Computer gone bad in 1999 Mustang 4.6 What is best way to replace?
Hi, my computer has gone bad in my 99 4.6l automatic. The car has may aftermarket mods such as bigger injectors, supercharger, intercoller, maf etc. The current computer in the car does not sync up with the guys laptop who is dynoing the car. It doesn't do the handshake portion part correctly. So we havfe assumed that the computer is bad. Now the real problem. I bought a new computer where the part number was almost exact except for the last 2 number in the sequence, it was from a 99 4.6 automatic car. But it doesn't run in the car at all. I spoke with ford and they said the computer needs to be flashed to my car even if the specs are correct. What should I do here, has anybody gone through this experience? I am thinking I should just have my existing one repaired. Any suggestions? thanks.
