Thank you for providing this SW for free.  I had trailered my track car 6 hours away from home when my p38 developed an EAS fault.  The vehicle did not drop to the bumps, but it appeared that the suspension was disabled and I would not have been able to reconnect the heavy trailer.  I downloaded your SW at the hotel and cut up a serial cable  in the parking lot the next day.  I  was able to clear the fault which was reported as a pressure switch stuck high.  I loaded the trailer and allowed the suspension to level back out.  I then took out the EAS relay and made the 6 hour trip back home without any more problems.  As an electrical engineer, I really appreciate the work your put into this software.  I believe your SW saved the day.  Thanks!!
