03-04 Mustang Tuning - Don't Bother - Super Charged 4.6
Currently not real impressed with the ability to tune the 03-04 Mustangs. The scanner is so bogged down it can't possibly be in the correct cell. Very limited channel selection and several needed to create graphs seem unavailable. The TPS sensor will read 0 to 100 with the car off and scanning, but will only read in the 23 percent range at WOT. The display on my WB showed it going lean but the and the log file shows it rich. The Dyno RPM showed 4500 when I lifted, but the scan only shows 3500. I can't make heads or tails of where the commanded Lambda is coming from. I have The Tuning School manual for Fords and have successfully tuned a 2005. I was told these could be tuned by using the Beta Version and having it reflashed at the dealer so that I could read it. (Was SCT). I had to have it towed to the dealer and it cost $140 at the dealer. Add in the tow and credits and I nearly have $400 to just get started. There seems to be no interest in these vehicles due to the lack of response to my other thread. Do yourself a favor and install a Holley EFI system. Somebody prove me wrong if you can!
