[QUOTE="ZOSO, post: 7878260, member: 17386"] I dont think a person that has never tuned it before would not have that big of a problem. If they are good and know what they are doing they could figure it out. It may be expensive tho. As dialing in the injector slopes and fuel trims will take some time. since your in arizona you wont have too bad of cold start issues. Now just as a side note do it in the summer time. As winter e85 is more like e60-e70. So if you tune it during the winter months and when you go to summer blend it may be leaner. A good starting point would be slope the injectors ~30% smaller to fool em so they spray a little more. And use a wideband for gasoline and just tune to the regular afr you normally would. e85 stoich is 9.xx:1 where as gas is 14.7:1. Which is lambda. so think like an ecu. lambda is lamda. doesn't matter what fuel it is. the wideband is looking for lambda. so 9.xx or 14.7. And in the mix you can add timing thru out the whole range. [/QUOTE]
