Thanks for the offer Nick. I messed around with the PC last night and everything seemed to work fine. I could upload and download maps with no issues, no run-time errors, no "not responding" warnings. I told my neighbor I'd take the one he offered me and if the one I'm using starts acting up again I'm done with it. If there's any issue with his I may take you up on your offer.
I did find out what was causing the fuel problem with my map....somehow the hardware setting got changed to TBI from MPI. It's a little confusing if you're not careful when you're uploading and downloading programs and changing things directly in the ECU. I don't know if that setting was a result of a data transfer problem or what caused it. I changed just that setting in the ECU and it fired right up. All the RPM cells seem correct now and everything is looking good for now.
I adjusted idle screw down so the IAC is controlling the idle and it seems to be working fine. Then I re-calibrated the TPS settings. The WB O2 also looks like it's working well. I'm unsure where I should have the idle spark advance set and the Holley map has it at 18 degrees. How do you determine what's optimum? Maximum vacuum? I haven't measured vacuum yet.
One other thing I tried......I got the engine to about 200F and wired the fans on at full speed. In just a couple minutes the temperature was down to 160 and stayed there. It was about 60 degrees in the shop (it was 70 here yesterday) but based on that test I think my cooling capacity is going to be fine. I thought I had a 180 thermostat although I really can't remember what I bought.
Still can't get the PS pump to work. I may have to remove it and see what's wrong. It's turning clockwise and I thought all of them turned the same but I found out they don't. I wonder if S&P screwed me up and sent me a reverse-rotation PS pump....how can you tell by looking at it?
