Also,You are not comparing apples to apples here. Do regular flexfuel vehicles run like raped apes who you substitute gasoline with E85? No because they run much more conservative tunes.

I would call it the only "complete solution." Even a genius would benefit from it. I'll explain below.

Incorrect. E85 blends change throughout the year and Shiv did some testing that proved that its very difficult to predict when and how you fuel blend is mixing. He started a thread about it, I'll look it up for you if you missed it.

Incorrect. PROcede and Cobb have full ignition control. JB4 cannot advance timing it can only retard it, and that's only if you have the latest G5 board. Previous versions rely on the factory knock sensor to retard timing

Awesome man! I wish we had E85 here.

Benzy - You are I have had this discussion before. I'm not really sure how anything you said refutes my previous post. My takeaway is that you haven't dynoed your car and you believe in logging. Who doesn't?
such a fanboy, are you actually running the e85 sensor? logs?
