About 5minutes after adding e85 my car stalled a stop sign.. I have not been tuned for e85 yet, but just wanted to 'clean' the gunk, and change fuel filter before my tune next month.. It does not see boost at all, maybe 2-3psi?, if that. Question is, this is normal right, just needs idling adjustment by tuner? It drives totally fine besides that. Thanks

 

Did you do injectors and an upgraded fuel pump? Are you not getting enough fuel with the switch to e85? I don't think you included enough information for us to have the correct context.

 

Oh sorry, 255lph, rc 1000s, & 65mm tb are the only changes, but car was idling fine with these parts, until adding e85. Then about 5 minutes later, stalled.

 

You CANNOT simply throw in e85 and expect the car to run or drive without a tune.

Its totally different then race gas which can still drive with, e85 require more fuel then regular gas.

Are your injectors scaled for pump at all?

 

So, is it not safe to run like this, even at no boost? Too lean now, should i drain it? runs fine if i keep it above 800rpms

edit: these injectors were purchased used, they smelled like pump, so am assuming theyre scaled. is that a big deal for normal granny driving?

 

Is your car been tuned since putting the injectors in?

I wouldn't run it in boost. At least throw in a mix of 50/50 minimum. Out of boost probably be ok but not recommended.

 

injectors don't get scaled at the injectors they get scaled in you ecu by tuning.

 

e85 is 85% ethenal which im sure you new but that means theres very little actual fuel in it which is waht your motor needs so thats why you need larger injectors that can spray more in at a time so you get the needed amount of "gas" in it and if the injectors arent scaled then theyre just spraying at normal stock settings... like said above scaling is done from car to car through a tune not from injectors

 

^ah.. lol. thats why i go here for info.. you guys rock!! I need more confirmation though, about leaving the e85 in.. i really dont want to drain it.. theres 5 gallons of e85 and about 2-3 gallons of 91pump. can i just cruise around and burn it? until i can fill up on 91 again..

car has not be tuned since 1000s, just installed along with tb.

 

injectors are scaled during tuning, so if you're untuned then they are not scaled

 

i dont htink i would leave it in there its prob not good for the car and its relatively cheap so idk if its worth a couple bucks worth of gas or some potential problems to your motor? but i have no proof of it being bad for you motor im just speculating so lets see if anyone else can chime in

 

i cant fathom how ur car even idles/drives with 1000cc injectors untuned... it took me a week to scale those and still had no luck, had to get them professionally scaled

 

^ Well my previous tune was with 720s, wonder if that has something to do with my car being able to still run. idk?

 

hmmm thaat may be helping you out a little... when i switched to e85 i put 1000's in and the car barely stayed on its idled like **** but would stay on so idk maybe those 720s helped a lil

 

I see, hope thats the case then. thanks for your input
