In Europe many running E85 to save cash at the pump. We have ridiculous prices. For those who say it will kill the engine well back in 2004 Mercedes made a C320 sedan FFV. FFV as flex fuel version and have same internals as our N/A. I crawled diagrams parts list etc etc and the main difference is the Bosch ME2,8 had a different fuel map and bigger injectors. On my N/A I’m on the work of a conversion. The only thing needed is specific injectors, a tune and AFR reading. That’s my 2 cent for doing it good. Some uses piggy backs and it work but I don’t like to trick the ECU. Regarding fuel lines, and seals they all are from NBR and therefore E100% résistant.
N/A would need 240cc injectors, for normal driving application or 300/330cc injectors for racing use.
SRT6 would need 550cc for normal street use and 730cc for racing application and powergains.

thank you to John and AMX for both of you looking into this. I’ve been trying to do a full e85 conversion for a long time now but my research has always come up short.
To john, the only problem I’ve seen with doing the FULL e85 with the tune (and changing to larger injectors of course) is that from then on you HAVE to only use e85. You can’t switch back to regular gas unless you get a retune for the car.
Niw this points me in the direction of the kits that companies make to convert your car to e85. Doesn’t require a retune because the kits run sensors for e85 % and they have PWM changers that run inline with your injectors to increase the PWM single to use the correct amount of fuel for e85.
With that ^ you can use pump gas or switch back to e85 on the go. But... I don’t know any draw backs to it and would like your guys input.
Also AMX I have been using 30% like you had said and I do notice a slight improvement. Especially in the mid power range.
