TUNING & DYNO DATA
Get the right tools for the job. Over the years, it's been stock, Ron Zimmer, Accel DFI by Cartech, Mike Licht of Modern Musclecar and now ME via LT1 Edit

 

On to tuning!  LT1- Edit is the cat's ass!  Now the ability to tune the OBDI
pcm is available to the home hobbyist. It runs in Windows, so those laptop's
kept around for just running Diacom aren't going to supply the horse-
power required. Heh, more power needed.... Isn't that always the way!

The above chart isn't from a Dynojet, Mustang or any other dynometer known to man. It's from my new version of the TTS DataMaster software. Tuning requires close evaluation of all the data output from the pcm. Now that I can program within a Windows environment, data logging in the same environment was in order.  The answer was the Turbo Shop's software.        
       
       
It's so much more comprehensive than Diacom, cheaper and has this great feature to plot out these dyno graphs. The same math that's used on the professional dyno's is put to use. The spikes you see is a function of the data stream coming through the ALDL / pcm. So the author has put a filtered "second order polynomial" trend line (the bold, smoother lines) to assist in the evaluation of the plot. The solid black cross hair line is a line that you move with your mouse that shows the rpm and value in the upper right box. Real nice little add on to a data logging program. Data Master is the one to have!  The above chart is on motor only......
