2001 GT ECU?

There are some slight differences in some of the sensors. Like I think 2002 is when they changed to the larger MAF and pink injectors, so there would be some variances in the tune. Unless yours is shot there is nothing to gain from it.
 
My buddy has a 2001 GT and he thinks the ECU went south on it. We have found a 2002 GT ECU locally but we weren't sure if this was a direct swap or not. I thought it would be because most handheld tuners cover multiple years
within that period.
