Just installed autocal from Idaho Rob (ATP). Question is how can I tell if the tune is really working? I have not noticed that great of an increase in performance. I have the dsp5 switch on 4 which is Economy 90HP. I have checked the switch through the autocal and the switch is working. Is there a way to go through the autocal to see if the tune is indeed functioning as it should. Also I got a code 2610 today, first time thats happened. It reset, I will have to wait and see if it happens again.
