You have the PJ3 system correct?
I have the PJ1 system. They no longer sell it or support it. Cody, the tech, that knew and helped with the system has moved on. I have tried the new Professional Products forum also, but they pretty much ignore the PJ1 systems. I can't find anyone on the internet that has a PJ1 system running satisfactorily. I'm on my 3rd computer and 2nd fuel pump (returnless system) and among other issues, I have a bad lean bog under acceleration at the track around 3,500. I'm too afraid I'm damaging my pistons or valves with this lean condition that I have not been able to correct.
I plan on keeping the computer and wide band O2 sensor to help tune my Holley double pumper. I should still be able to read air/fuel%, vacuume, coolant temp, and RPM and I should still be able to Data Log my runs to help dial in the new carb.
