For me RTT is by far my favorite feature available for HPTuners.
When moates released the roadrunner earlier in the year my initial reaction was OMG because the price was just so far out there...for the little time you might save on a tune it would take forever to make that money back especially since you need separate hardware for each PCM that $ could add up to over $2500 not to mention the actually tuning software itself.
Once HPT finally announced they were going to enter the Real Time Tuning market I really wasnt sure what to think, what was the price point going to be? how functional was it going to be? Well damn if they didn't blow all of my expectations out of the water, not only was it free for anyone that had already purchased one of the custom operating systems it was included in their current custom operating systems at no extra charge, how can you beat that?
I've already purchased the unlimited SD custom RTT & literally use it on EVERY LS1 fbody I tune now...with its simple 5 minute application, ease of use & great price Its definitly my favorite feature thus far & will only get better with autotune.
I'd like to know what your favorite features are in the program & what you use on a day to day basis that makes life/tuning easier or more fun...whether its the histograms that have nearly made excel obsolete or standalone datalogging or whatever, post it up
