OverKill Tune with E85 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Dhaliwal559 · 06-14-2016, 05:07 AM

Alright guys. I'm really lost..
I have a 2015 Camaro 1LT/RS.
My current mods are
- RotoFab intake
- OverKill 80MM throttle body
-JacFab intake spacer
- muffler delete with quad tips
- Vitesse throttle controller

And that's all. Now I'm ready to get the overkill tune. I'm stuck whether I should get the normal tune or the e85 one that's 200$ more.

If I get e85, does that mean I'll always have to fill with e85, or can I switch to 91 whenever there's no e85 nearby?
And to switch back to 91, do I gotta change my tune?
Also what's power / torque increase difference between e85 tune and normal tune

Also can I use my VTC with overkill tune? I kind of don't wanna sell it lol, my favorite mod

I pretty sure the car can adjust itself with the module will supplies you with when it comes to e85/91. The car will be able to sense what percentage of the fuel in your tank is e85 and will automatically adjust your tune accordingly. in my opinion if you have a station nearby I would definitely go for it. you should see another 20-30 wheel hp just from the e85. im almost certain on all of this but im sure others will chime in in the morning. sell your vtc, will can help you with the throttle response.

I'm in Fresno, there's plenty nearby, and holy crap! 20-30 more from just e85?! How's the gas mileage difference from 91 to E85

most lfx's are dyoing in around 280-290 wheel hp when tuned. I recall seeing a forum member come out with about 315 wheel hp on e85. you will burn a lot more fuel even if your not putting your foot down. It can burn up to 30% faster than 91

Dhaliwal559 · 06-14-2016, 05:23 AM

Man.. That's a lot of gas..
I just looked online.
The only e85 around is here from arco... How's arco e85??
I've only poured chevron 91.. Never even look at arco. If I run low, I keep driving until I found a quality gas station

im from jersey where theres maybe one or two stations in the entire state so I cant answer that question, im not sure

You can use the VTC, but you wont need it with Overkill's tune.

E85 is great for power, and you will definitely notice it all over the RPM range with E85. but it SUCKS for gas mileage. I think i average 13-14 on E85. But with the Overkill E85 kit, you can switch back and forth to gas if need be.

I had a 450 mile round trip last weekend. Ran gas. Got home just as I was about to need to fill up, and switched to E85. No change in tune needed. As long as Overkill sets you up to turn on the flex fuel sensor in his kit, then you are set!

Badmaro95 · 06-14-2016, 05:43 AM

The sensor from the e85 kit will read the alcohol content in the fuel so you don't have to fill up on only e85 you can switch back to 91 without having to switch tunes

Just make sure to get full benefits you try to switch when you are on empty or as close to it as possible.

I gained 26 hp and lost 4 mpg. But, e85 is almost a dollar cheaper than 93 here, so IDGAF

Shawno72 · 06-14-2016, 12:21 PM

I use my vtc with all my overkill stuff and love it.

Dhaliwal559 · 06-14-2016, 01:12 PM

Alright guys... Gonna pull the plug

This seems to be the great divide. Some of you guys claim there's no point of having the VTC with the overkill tune, then others claim they work great with tunes. Haha which is it? Have some of you guys just not used the VTC with the overkill stuff?
