This posting is a high performance engine management computer chip primarily designed for use with 2.3 turbo Ford four cylinder applications using the PC1 calibration (see below for more details on application). This chip "piggybacks" the existing computer and optimizes full and part throttle settings, raises rev limits, and removes speed limits (where possible).
I had used this in a 85.5' Ford Thunderbird TurboCoupe (Manual) and it worked well with my particular vehicle. I have since sold the vehicle. Having the rev limit can be nice for a high performance application with a manual transmission.
Asking $40/obo buyer pays shipping from Springfield, VA (22152)
