typical scan values for stock '91??
Trying to diagnose a very rough idle for my stock '91. The rough idle is present when the engine is cold or warm. Changed plugs, cap, wires, fuel filter, cleaned IAC and throttle body, checked timing. No trouble codes. I suspect It could be my Multec injectors, but I want to review the scan values to make sure there are no other problems. I am using Tunerpro RT. What are the typical scan values for my car? I know it's asking alot, but if anybody out there has a tunerpro log session file for thier stock car at idle (that runs well of course) and they could send it to me, that would great. That way I could run the session from Tunerpro and copmpare to my values.
Thanks,
Howdo

how I did it
I like the tuner pro rt software. It's free. I only plan on datalogging, so I don't know good it is for the other stuff. I made a " 2-transistor circuit" from the plans on the old craig moates website. Go to moates.net, then hit the link for the old web site and check under software. You might be better off buying the cable from craig moates (it runs through the usb port), I think it is around $70 total. Send him an e-mail and he'll tell you what you need. The problem with my circuit is that is was kind of a pain to get all the parts together. By the time I bought the circiuit breadboad, components and enclosure, and serial port cable, it was about $35. Spend a little more for the good hardware and plus some possible support from craig if it doesn't work.

I don't use TunerPro for scanning, but I can send you some Excel spreadsheets of my scan tool's output. Let me know what parameters you are interested in and if you want idle, part throttle, WOT, etc.
