| I don't know if this is true for TunerPro RT or other scanners with the 165 ECM, but I have had problems getting and staying connected to the ECM with my scan tool Turbo-link.
One thing I have found to minimize the problem is to connect the cable to the ALDL and computer port before I power up the computer and with the key off. Then turn the key to on but do not start the car, then power up the PC wait for all start up routines to run, then open scan tool application, connect to the ECM, then start the car.
This connects on the first try 99% of the time and reduces the 'lost communication with ECM' significantly.
Hope this helps.
Mark
