So I'm going to be starting off with my mods and first up will be E85 sensor and a tune. Still running stock motor and its an A8 tranny. I've not had any experience with E but I know many have and its plentiful in my area. Not planning on CAI as I've read that there really isn't any pick up in RWHP, the previous owner did do a drop in K&N filter. I will also add a lower T stat from the stock 195. Has anyone done the upper cat delete? Won't do long tubes until winter. I would guess it might make 20 to 25 rwhp.

Geeezzzz thought somebody might have done this.

ErnieN85

Yes it has been done search for E85 conversion might be in the C6 forum

99vetteran

Cool, I've searched this one but will check again. Thx

My results will probably be "apples" to your "oranges" but... On my 2015 Z, with a CAI and 9% overdrive pulley and other supporting bolt-ons, going from 91 octane premium E-10 (the best available here) to E-70 (also what's available from the pump) I was able to increase timing from 16 degrees @ WOT to 28 degrees and the power jumped by over 60 rwhp. On a NA engine I wouldn't expect anywhere near that gain, but... should be worthwhile anyway.

A side benefit, running E-85 without cats Vs. E-10 premium without cats, the smell is not only less, but is "different", not objectionable. My opinion.

A lot of the guys on Camaro6 forums have done E85 on their LT1s. They have claimed gains as high as 30rwhp. But if you watch Raceproven Motorsports Youtube, they had an episode where E85 didn't produce very much over 93 on a mild LT1 build.

Thanks for the feed back. I don't think I'll see close to the 60 but maybe 25 to 30 as I've read on the Camaro6 forum, I also watched a video on how to set up my Hp Tuners for E. Still need to do that once I get my Sensor installed. I'll do some other mods later this fall, long tubes, cat delete. I need to learn a little more about NOS, wouldn't mind just spraying 100 shot for the drag strip. Pretty safe.

I gained 30 rwhp adding E85.

99vetteran

I'd be happy with 30, but we'll see next week and at the track right after that. I went 12.06@118 a week ago in the heat, maybe some decent gains of a couple tenths and we'll put some more timing down low to handle the taller tire I'm running. That probably hurt my 60ft. It feels so slow compared to my 9 second camaro I just sold.

MeanRay1

I bet! After running 9's everything is gonna feel slow lol!

I had enough motor and blower to go 9.00 but I didn't have 10 grand to spend on a fuel system.

A guy I run with at Sebring has a 17 GS M7 that he’s tuned on corn. Said he made 460 at the wheels with long tubes and E50. He absolutely loved it, made a huge difference when hitting 4th gear.

99vetteran

Thats a bunch for a stock GS on corn. Looking forward to getting it done next week.

Getting mine done tomorrow with a tune. I'll let you know the before and after results. I think they are using the Dsx Sensor. Gonna run it down to almost empty for the best results. Then fill it up on the way home with E85. I have another race this coming weekend. My Vet ran 12.06@118 which I think is pretty typical of these cars. Like to run 11.80s before the long tubes and CAI. Car is bone stock right now, need more timing on the launch since the drag radials are 1/2 taller then the stock 285's

Got some good news and not so good news. The good news is that Killer Performance in Grain Valley Mo did a great job on the DSX sensor kit. I didn't realize you had to pull the passenger front fender liner out as the ecu is located on the back side of that. I almost ran if out of fuel trying to get there with the least amount. Said it would go 33 miles but it was dinging calling me a dumb *** for trying to run out of fuel and since the dyno was not at their shop I didn't have enough fuel in the tank to do a 93 octane pull. Plus I had to drive 5 miles to get E85 after the sensor was installed. So I'm figuring it would have made about 395 rwhp and that's what my Lt1 Camaro made on that dyno when it was new and they are both A8 trans. So the first pull it made 426, he made a couple adjustments and the second pull which was basically back to back and it made 431. We let it cool about 25 minutes and the third pull was 434. For some reason it was not showing the torque as he was having problems with the tach connection. I think torque would have been close to the same. I didn't really care it will show up on the track in my 60 ft times. So in my opinion its a good bang for the buck. Did go from 29 mpg down to 22.5 on the 130 mile drive back home. I did have a chance to get on it from a dig on a nice concrete road and it pulls much harder then it did on 93 octane. The E content was 70% and it has no 93 octane in the tank now. Good to go and I'll see it runs 11.80s now like I think it will. Next will be long tubes, cat delete and Cai.

Hello, I wanted to bump this thread to get a bit more info on the E85 Sensors.

From what i seen and read the sensor helps read the ethanol content but, what good is that if most kits do not offer a gauge for the C7 set ups? if you are not able to see the ethanol content, what is the purpose of the sensor? Since it is pinned to the ECU does it allow to run Octane lower than E85 safely even though the ECU is tuned for E85?

I ran E85 on my 13 Coyote for 3 years without a sensor and never ever ran into any issues and now I'm curious to know if the sensor is even necessary for the C7.

99vetteran

I use my HP Tuners to check the E content. I don't worry about it as much until about a week before I go to the strip. Then I'll make sure I only put E85 in and its usually 65 to 70 percent E and the timing is built into the tune with 4 degrees of timing for the highest E content and as it lowers the timing will be pulled so I wouldn't run E without a sensor.

Yes, with sensor installed and activated you can run any ratio of E85 to gas. When tuned properly the PCM will adjust to whatever fuel mix that you have.

For monitoring E85 contend you could use the P3 gauge. That is what I will be using in my Z06. Another option is to use the Banks iDash gauge. I have an iDash in my ZL1 and it is a great gauge.

I have a heads/mild cam, fbo M7 '14 Coupe... picked up 25rwhp with flex fuel sensor and retune.

The main purpose of the sensor is to feed the ECM the percentage of ethanol in the fuel. With that info the ECM can set the A/F, timing, etc.

That we can read it is a bonus. I run the Interceptor gauge in the hidden cubby, it reads out the percentage of E along with MANY, MANY, other data items on the bus.
