So I need new injectors and a pump anyway and after a petition and multiple complaints the servo up the road has pump E85 again after being broken for two years. ( Perth has five whole E85 stations) Is the stock LS1 pcm capable of running a flex fuel sensor? Or no I need to e38 pcm conversion or stand alone? I've not ran E85 on a non boosted car but I'm assuming being able to run like 35 degrees all in and not 28 will create a pretty big bang? 10.5:1 Ported heads 231/236 111+1 LSA (custom grind but think I've finally decided) Tri y's , high flow cats twin 2.5's 3.5 K stall 3.46 diff gears I guessed the race weight of 4000lbs with me in it and Martin Smallwood reckons I'll get a 115-117 mph trap. How much difference will E85 make on my set up?
