When it comes to OE level tools. I have to say the Ford IDS is the best for your dollar. The engineers at Ford have put a lot of effort and thought into their tool. Offers great graphing's of multiple PIDS, Bi-directional controls, Network tests, Power balance, Relative compression test, fuel volume tests and saving of captures. Only drawback which is minor is the length of time you can take a capture. You can only take a 2 minute capture when triggered. The program has a little learning curve at first but all in all it is one of the best OE software applications out there.
The cost of the software went up modestly this year but well worth the money and the ROI can be recovered quickly.
