So our computer died. finally able to get codes and instal workstation 6.93. Cannot get it to autotune as we need to coarse tune first. Manuals say 'servcie use only', agilent tech support says no service manual available. I have made the TFA but cant get over the 'poor slope values' error, can anyone help? Is there a service manual out there or a pdf guide that could be shared with us here at UC Davis so we can use this TQ?
