Loves it, has the timing wound out 14 degrees advanced on the distributor cap lol, ran consistent 16.9's at Calder last Friday Link to comment Share on other sites More sharing options...

turbotrana Member 2,586 Member For: 21y 8m 13d Gender: Male Posted 19/07/14 02:00 AM Share Posted 19/07/14 02:00 AM I found that E85 actually runs better leaner. I disconnected closed loop and leaned off the injectors to run leaner than stoich air fuel ratios on light acceleration and cruise and I think it runs much better than running at stoich. I am talking about 18:1 petrol air fuel ratios. However I noticed that there was not really much improvement in fuel economy for some reason.The tuning window for E85 is much wider than petrol, I think the lean misfire limit was around19:1 but in some instance higher.You might be able to tune E85 leaner and not affect emissions too much as the cooler temps don't push up NOx too much.The problem is you can't learn very much with the Ford ECU flash tuning, You really need a live tuning EMS to learn about tuning and different fuels.
