nope, pretty much just injectors and the fuel lines need to be e85 compatible



rail is good



most will run a 255 fuel pump anyways and a regulator



hard part is tuning. e85 has a different stoich

 

around 9.7:1

 

Any updates Jon?

 

Yeah, sorry to hijack the thread. I just wanted to get that information out there, after all it is a turbo build thread.



Although E85's stoich ratio is 9.7:1, when your gasoline wideband reads 14.7 it is stoich for E85 also. Just read it the same as if you were running gasoline.

 

did you do the tuning yourself?



cuz from what ive heard from quite a few people you "trick" the wideband into reading 14.7 with e85



i cant state that from fact cuz i havent messed too much with it

 

it depends on what kind of wideband you have, and how it reads. It will appear to read the same on wideband O2's that read in lambda.



lambda = afr/afr(stoich) so for each fuel at their stoichiometric afr they have a lambda value of 1.



gasoline



1=14.7/14.7



E85



1=9.76/9.76



so if you're running E85 but your gauge is set to gasoline, at stoich it will read 14.7, even though it's actually running 9.76 on the e85 scale, because the sensor measures lambda, not AFR.



whether it's reading gasoline, E10, E85, doesn't really matter as the lambda values are equivalent. I have an AEM wideband that reads in lambda then converts it to afr. pretty sure innovate and plx both do as well.

 

Hmm pinteresting. Thanks for the info

 

Yes I tuned the car on my own. It is a PLX wideband so it does read in lambda and convert to AFR.



Jon, any progress on the car?

 

I got the wiring hooked up on the haltech and all sensors are working, but I needed to adjust the fuel map. Car wouldn't start. I spent a few hours fiddling with it but life took over. I got a new job back in February. More money, but a lot more time in the office. Any spare time I do have is with the family or at the lake. I do want to get back to it though. I just think I need to start paying people to work on my car more now that free time is no longer there for me.

I'm even paying a friend to change the clutch in the v6 Tib this weekend. Even though I could do it in my sleep....figuratively.

 

I entirely opened this thread expecting a, "Welp, I sold it."



Throw a few hundred bucks at someone and have 'em get it tuned for you
