give
this a try, I just picked one up off ebay for a bit under retail. you will also need to get a palm but you can get a palm m105, thats all you really need anyway, off ebay for pretty cheap
the software pulls codes, lets you view sensor, run dyno software to get numbers, and there are a few other things like recording and freeze frame type stuff
I am going to mount the palm in my car and use it real time to watch what is going on, and to gather info, like it will tell you fuel milage and you can have it say show you timing advance at the same time
this one does some of the same things but you can't use it on all cars, just the ones that have the same protocal as Fords do
