so i have everything i want parts wise before my tune for the season. but from what i have found out oio does not make the switch back to e85 from e70 until may and even june in some parts. i really dont wanna wait that long to get tuned. how much of an affect will being tunes on e70 be? will that be worse than a 93 tune? i 100% have my heart set on e85 but i really was looking to get tuned towards the end of march/beginnging of apirl. what do you guys think? and dave is handling my tune so if he could chime in with what he feels that would be good too.

 

why not get tune on both just to play it safe?

 

because im a 21 year old college student with a budget lol.

 

it does suck when youre on a budget and trying to play... were lucky here in vegas to have e85 a plenty year round, well usually lol. let me ask you this how much of a difference in price for both tunes, maybe you outta save $$ that way you dont have to stress about having to wait for the season switch

 

i may but its not really the change over that bothers me. but more the initial tune. as ive talked to people being tune on 85 have no problems with 70 but i doubt the other way around. plus id rather be tuned to the highest potential possible.

 

also curious

 

have you talked to dave about it? since hes the one tunning you..

 

I can only hope e85 will come around my way one day...

 

i figured id do some researching and see what others had to say before i called to bother him. i ask him enough questions as it is lol.

 

good question. I ve been wondering this myself. Im going to keep a close eye on my wideband. I was just tuned recently(probably e70). I expect my tune to lean out alot when e85 is back in. My air to fuel was 11.7;1. So when I see it get lean, Ill have to add fuel to the map I guess. Ill probably be able to more boost also and make more power.

 

if need be ill source a place in florida or texas and have some sent to be tuned on. idk if thats even possible but hopefully i find some info soon.

 

so from everything i have found the minimum octane rating of 105 posted on the pumps is pertaining to winter blend e70. which is still an arm and a leg over 93. so i guess my biggest question is will i see a huge difference when they switch it back to e85 for the summer? as in will my tune be screwed?

 

Well I talked to Dave about this recently and before I get my black tuned he wanted me to wait for e85

 

I wish I had E85 around my area

 

makes sense. but sucks as idk if i can wait that long to hit the track lol.
