@Supporte if you are just starting out, concentrate on 1 particular brand to start and go from there. VW is some of the most well documented. Check out some file provider services. You can purchase a few tuned files and map-packs and compare them to stock to see what sort of changes are being made. You're going to need to look into WinOLS at some point. If you are lucky you may find some XDF files for TunerPro but those are harder to find. These videos are useful:

@Supporte I've only tuned gas vehicles so far. I've not used MPPS yet, but have tried similar tools such as PCM Flash. I use HPTuners a lot. I has a very nicely polished software package but does come at increased cost. What brands of vehicles are you interested in?

Sorry about that! Edited.

Hi all, I found this website on google while searching for wiring information for some Automotive ECU tools. I am an automotive technician working primarily on Engine Control systems, ECU's, TCU's etc. Some times for the purpose of repair and other for the purpose of tuning. This can involve altering the software on the ECU and sometimes replacing or programming the Chips directly. I like to try and repair things rather than replace them.

Check and see what common resources are installed on the working version. Usually its going to be some C++ runtime that's required either x86 or x64 - the version required is common to the program rather than the windows installation so try both and all years.
