I started with it, then went to ktuner and finally hondata. It was to aggressive on 93 octane and power would cut on and off on me. I tried there ethanol 30% map as well and my fuel pump was crashing above 5,500 rpm. Did some back and forth with their customer service trying to dial it in, but I wasnt willing to start playing with the spark plug gap like they suggested. I should have gotten a real tuner from the get go. Someone with a jb4 recently posted a dyno log and the graph is choppy as hell. I would stay away.
