A few days ago I decided to try out E85 In my SS. Even though they never equipped the SS for E85 I decided to try It anyway. Since It has the same engine as the pickups and SUVs have and they were equipped for E85 I figured why not. Anyway I had half of tank of 87 and filled the rest with E85 and have been topping It off with E85. So far I've noticed the Idle Is smoother, the throttle response Is better and It feels alot more powerful. But I have noticed I lost about 3 MPG's as the PCM Is giving It more fuel to compensate for the lean condition as E85 has less energy. But It's still worth It as gas has skyrocketed around here. It has no starting or drivability Issuse at all so I'm assuming that means the fuel pump and Injectors have no problem keeping up with the demand of E85. But It does throw code P0171 for Bank 1 lean, obviously since the E85 tables aren't enabled In the PCM. But I'm gonna add the sensor to the fuel line and tune It so It can run both fuels reliably and not throw the lean code. I checked the fuel lines coming from the tank to the engine and they are the same across all engines so there E85 safe. But just thought I would let other SS owners know of my experience. As of right now I'm gonna keep running the E85 unless I start to have drivability problems or I go somewhere that doesn't have E85. Will keep this updated.
