    2000 4.6 cobra engine ecu tech

     



    i am installing a 2000 4.6 4cam cobra engine/5 speed trans package in a kit car. this will be a street car and the engine will remain stock. what changes do i need to make in the stock ecu unit. i assume there are functions of the stovk ecu unit that should/can be eliminated in the kit car. it also must accept the plug in emission controle tester.[car in massachusets] what is better;a custom chip or a tuner. what products/supplyers do you rercommend? we have not worked with a computer tuned engine and need some good advice. appreciate any help. thanks george tongascrew@msn.com

    Your ECM doesnt have a removable "chip" so a reprogram is your only option regarding making a change. Older ECMs had the memory on a "prom" which plugged into a socket.....hence the marketing of a replacement "chip" with a new program on it. Newer designs (especially OBDII stuff) uses on board memory that is not removable. There are some "modules" that attach externally to the ECU.....usually you remove the connector and plug the module in between the ECU and the harness. These dont reprogram the ECU, they only modify the signal inputs or the outputs.

    For the new stuff, when the ECU is built, a program is loaded. You see a lot of activity for the LS1 stuff being reprogrammed....dont know who is competent with Ford designs. Suggest you do an internet search and/or contact some Mustang performance shops in your area.
