I got in some successful runs in TX on the dual fuel set up. and kept resetting my personal best in my car all weekend. I will post a video of some passes once I get through all the footage. It was nice not having to worry about buying E85 at TX2k when the local pumps ran out from the large amount of cars buying it sense I was full when I left KC and still had fuel to spare after the weekend was over.

No need to dry fire injectors, the pcm grounds the injectors to fire them.
Each set of injectors is powered by a relay. Pump gas injectors can be powered by regular ignition source, E85 injectors by hobbs switch or any other snake oil tricks.

That is pretty trick. A friend back in FL did this in 2005 with pump gas and c16. Crspysqirl (sp?) I believe was his name on these forums. Worked great! I believe he used 1 stock pcm and stock injectors. Then stock ECM and HP tuners on the second set. It's been so long I don't remember. Maybe he will chime in.
