My 99 Ranger has a problem with detonation. Because of this I must put in supreme unleaded. An April 2000 technical service bulletin from Ford says that the ECM and ignition module have to be replaced. I have replaced the ignition module but the current, updated ECM is $400 at the dealership and is not available anywhere used. I picked up a 2000 Ranger ECM at an auto salvage yard ( I figured Ford would have the bugs worked out of the ECM by then). Same specs as my truck, 3.0 V-6, 2wd, automatic, flex fuel, etc… anyways I put the 00 ECM in and my truck would not start. I read that ECM's have to be programed to the individual vehicle. If this is true then can I get the 00 ECM to be programed for my 99 Ranger?? If I can then where do I have to go to get it done?? Any information would be appreciated.
Autotech thanks for responding. Are you saying that I can take the 00 ECM to a Ford dealership and then can flash it to fit my 99 ranger?

I have a 2003 Sentra with less then 90,000Km (56,000Miles) so its still got lots of life in it, too bad its missing the one thing that every new car has these days; an AUX jack in the dash. I don't want a gaudy flashy 3rd party radio when I can get a stock one from an auto salvage for 150 bucks and it does everything I want and matches the car.
