does anyone know where i can get an ecu for a 2003 gt besides the ford dealer, i need one buy march 15 and my ford dealer is nuts....
A lot of the popular performance shops will have a few stock PCM's lying around. Try giving a few of them a call. If you don't have any luck, try the salvage yard or the dealership. Maybe do some searching on some of the classifieds on other websites.
What happened to your PCM?
well be carefull as 2003 is unique to a 2003 so you can't substitue another model or year
is your car an auto or stick?
it is a stick, my code is xsh1, do the 2003's only have this code, im under the impression as long as a get a computer with this code and the donor vehicle is a 5 speed i would be good?
This is a very good thread. A few months ago, I went to my SCT tuner to have a SCT flip-switch chip installed but my ECU wouldn't accept the chip.. When we would try to start it would just turn the fans on. It wasn't the chip either as we tried a brand new chip as well. We ended up having to flash the computer for just one tune.
First off, does anyone know why this would happen? Also could this be solved by replacing the ECU? If so, what part number would I need? The car is a 1999 Mustang GT w/ the T-45.
PCM's can have a mind of their own and they will do all sorts of weird stuff. Sometimes after a recalibration or re-flash upload to the EEPROM, the fans will come on and that's it, no start no nothing.
What that means when just the fans come on is that the communication somehow got hosed when your tuner was programming the chip. When you put the chip in, the PCM wasn't happy and it goes straight into what is called FMEM( Failure Mode Effects Management).
You probably just needed to take the chip back to the tuner and have him re-burn the tune.
Is the car running fine now?
no luck yet, no classified ads, no ebay, and no junkyards, someone has to have a totaled 2003 gt...
That part number is indeed off a 2004, but you have to be careful because Ford used different hardware platforms within the same model years.
For example, on 2004 year models, in the middle of the year Ford switched from the MPC(15 C was the last one on that platform that I know of) hardware to the newer MP2 hardware. You need to contact that seller and ask him what the specific PCM code or hardware platform it is.
To make it easy on yourself and the shop doing the R&R, try to look for a PCM that is built on the MPC-14G hardware platform. Calibrating/Programming different hardware platforms goes beyond normal tuning skills and most techs probably wouldn't know how to do this. The car would run but, if they don't know what they are doing, they won't be able to get it right.
If you come across any other PCM's that you can get the part number or PCM code, I can look them up for you and let you know if it will be a direct swap.
so what your saying is the number on the upper left corner of the white tag on the ecu has to say mpc-??? for it to work on my car, i found another that says mp2-18c, but from what im understanding, the mp2 in that code indicates its the newer platform and wont work with my car...
