I just got done reflashing my BRZ with the updated Stage 1 map. The reflashing process is easy when you use the tutorial. The program threw a stupid error code for me, but I was able just to re-start the "Program ECU" function and it went fine. Thanks again for your help John!
Before I turned in for the night I wanted to do a test run on the highway. The torque dip in the new map seems further improved, as in there seemed to be more torque between 3000 and 4000 rpm, and the top end power still feels great if not better. No issues whatsoever, just an addiction for more power and an increased risk of leadfoot.
Now, I test out the upgraded pump gas tune and wait patiently until I turn back up on John's list for my E-85 tune.
Also: Datalogging function and realtime data monitoring is freakin sweet.
