At MacDonald Motorsports, the weapon of choice for Custom Flash Tuning is the SCT Xcalibrator 3. This unit allows the user to Data Log any Ford vehicle (1996 and up) with a laptop and the software that is available; free of charge, from www.sctflash.com This is convenient for adjustments on mail order tunes or for people at the track.
Data Log the vehicle, send me the file, I make the corrections and send the tune back to you ready to go.
