switching to e85 and 65lbs injectors and have a question. i know your suppose to add about 30% more fuel for e85 but is that with the same injectors. since im doing both at the same time from stock injectors do i first factor in for the injectors then add 30% or just the 30%? if i have to factor for both does anyone have a % to add or take away instead of tuning twice?
 


that is with the same injectors already dialed in for pump gas.

scale your fueling for the injectors first, get it running, then add the 30% and fill 'er up. tune from there.
 
thanks bio....bet she would have ran like crap with just the 30%. i figured but i had to be sure...do you know where to start when switching to the 65lbs injectors? with a full rebuild and a bunch of other mods im not guessing shes gonna start easy the first time as it is and would like to get her close as possible from the door
 
im not sure about scaling injectors, but i can only assume you'd want to run a ration in comparison to stock. stock injectors are 33 lb.

therefore, with 65 lb injectors that run much more fuel, you'd want to run (33/65)*(current values). makes sense to me, but i could be wrong. dont take my word for it.
 
well thats no help...no "thanks" for you on that one bio although i do appreciate the response. your logic sounds reasonable but im assuming someone on here will have a def answer.
