1999 Speedo calibration issue Superchips Flashpaq 3875
Ok I have read through all the post when I searched for SC Flashpaq 3875 and saw nothing pertaining to my issue. I purchased a used Flashpaq off of Ebay that luckily was not locked. I downloaded the Spark software and successfully updated the programmer. It has successfully connected to the ECM and I loaded a tune. I have recently lifted my WJ and want to calibrate the speedo however when I try with the programmer it tells me this option is not available because an ABS module is not detected. I called Superchips and the tech said it was due to the 1999 not having 4 wheel ABS. I have speed sensors on all 4 wheels and do believe it has 4 wheel ABS. Why is it giving me this message? Anyone else have this issue with there 1999 or have had success calibrating the speedo?
