IMHO, you will get a better tune if you are willing to learn and master the art yourself.
Why? Time. It takes a tremendous amount of time to properly tune a custom engine. With or without a dyno. I use both the dyno, and a datalogger on the street, and it still takes me months to perfect a calibration for one of my personal vehicles.
There are two DIY paths that are powerful and cost effective.
The first is the
http://www.moates.net path. He can sell you the J3 port adapter, the memory device, and the programmer and you can download the software from Paul Booth's site. Very DIY.
The second is the
http://www.tweecer.com path. They have a more commercial product and tuning software that is USB flashable in-car, which is handy.
As far as "how to" tune, it's all the same regardless of the software you're using the punch the parameters in with. The parameters don't change; they were created by Ford back in the early 80's.
Read a lot, use scientific method, and do it yourself. That's my advice. If you want help putting together a baseline calibration to get you started, email me and I'll help you free of charge. I've tuned over 1600 EEC-IV's, and developed a passive datalogger product called SnEEC-IV. I retired from the scene in 2004 to dedicate more time to medical device design. I do this automotive stuff just for fun these days. The system I used back in 86-04 was the Autologic System which is now owned by Diablosport. Actually, Diablosport is now owned by the guys that built the Autologic system...so I guess that's a better way to look at it.
