Got the serial cable from TAQ and worked on this. Now have serial WB, left the Analog signal going in so have analog WB and both sync to my WB gauge. We have data! Thanks for the help!
But I did try changing the stoich to 14.3 for fuel, it changes the settings for AFR in LC-1 programmer analog 1 and 2, so the 0 volt and 5 volt AFR were different and the data to scanner was off? But then again if PID is set for 7.35 to 22.39 and I send it something differant then that was to be expected.
Should I try to change stoich in WB, calibration and PIDS? Would it be worth the effort? Seems like a good idea to match fuel stoich to start good data and tuning? I've done this before with good results but in OBDI tuning software when you make changes to Stoich AFR it will change O2 - Rich/Lean O2 thres vs. Air Flow voltage values! I don't see any of those paremeters in the 98-00 Vortec def, so I don't know if Stioch is being changed properly.
