Update: Connected up the wiring and started the car up. I still have to clean-up the wiring a bit, wrap it or put in a loom.
Took a short drive and pretty happy with the FiTech so far. I set the ignition timing tables for 30 degrees so I could double check the distributor install position with timing light and adjust the pickup inductive delay (VR Advance 4000 in the FiTech menu). I must have got the base timing really close, I did not have to adjust the distributor. It was reading right at 30-degrees until I really brought the RPMs up and the timing light showed the timing advancing a few degrees above 4,000 RPM. Changed that VR Advance 4000 from 17.5 to 15, and now it was holding a steady 30-degrees through the entire RPM range. I then programmed the ignition curve back in near what the stock settings were.
Right now, I have the WOT (95 kpa map) timing settings pretty conservative with 30 degrees @ 3,000 RPM, and 32 degrees @ 6,000 RPM.
I still need to work on the idle settings. I found that when adjusting the idle screw to get the IAC within the range the instructions mention, you have to cycle power after making the adjustment so the TPS can re-set its zero position.
If weather is good, going to put some miles on the car tomorrow.
