I did the self tagged C1025 package (C replaces the S as its for California) I used the 305 upper with a 91-E85 flex tune.
The transmission laptop is being held up in Canada so that part is not done yet. the power and feeling you get when you hit it is crazy. Ive had a few 650 RWHP cars but never AWD this thing sticks and goes. the SC sound is perfect you can play with the gas pedal and not hear it or you can hear it if you want. It will drive just like stock TH also if you want it to. I agree with the 100s of others this kit is awesome and well worth the money. right now the TH is running straight 91 I just got tank down to 1/2 way so E85 will go in tomorrow. Doubt I can feel the HP increase but at least its safe that way.

I dont know a lot about E85 and first car on it so i try and read everything. To many horror stories about bad gas bad E85 the list goes on. this is why I went with the 305 pulley and flex fuel. if I run 91 (California gas) and put 1/2 tank or even less of E85 the octane will be well above the 91 and safe even if the 91 is bad. my lil head tells me even if both are bad the Octane will still be above 91 unless the E85 is way way way off im still safe. half tank 91 and half tank E85 (108 oct ) I even thought about getting a 55G drum of 117 and throwing a few gallons when at home. I used to have a buddy that would sell me 110 in drums way back in the day.
does any of this make sense or am I way off? Im very new to this so set me straight if something I am thinking is wrong please.

As a big ethanol supporter from various cars I can tell you that you absolutely will be able to tell a difference if the flex fuel tune is one right; ethanol content mapping on a full tank of 91 then add e85 in stages so that various content measurements can be associated with safe timing increases until you have a full tank of e85, at which point the max timing advance will be introduced. Because of this, when your content analyzer reads a higher ethanol content (from straight 91 to anything else) your ECU will increase your timing among other things and you will notice from 91 to full e85. Livernois seems to have a fantastic reputation, so there's no reason to believe they will do anything other than what was mentioned above! I appreciate the review as a spectator who wants to put the kit on but enjoys the thought of warrantee work :)

I think this is the exact route I will take. I live in AZ and the availability of E85 is not that abundant. I would like to hear from more owners with the "C1025" package.

yes its the s1025 except with a 3.05 upper pulley instead of the smaller 2.85. The 3.05 pulley makes about 1 maybe 1 1/2 less pounds of boost, and allows the hawk to take the timing with the lower grade 91 octane fuel.

Seems like if anything it should be called the C1000. C1025 doesn't make sense as the larger pulley will lose about 40 hp. Not sure if the OP mentioned any of this, I have the moron blocked.

Thank you for your reply. This just gave me info I had not came across yet. The computer cant adjust fast if I understand this correctly? If I was running 2-3 tanks of pure E85 then one day was stuck with only 91 my timing would be so far off I could "hurt" the motor? if this was to happen how long would it take the computer to figure out the lower content and pull the timing back to a safe level?

you say I will absolutely tell the difference between E85 and 91, about how much more HP do you think the E85 gives me in this set up? guess is fine Im trying to figure out if I should just leave 91 and small amount of E85 for octane safety. my luck ill get stuck with 91 some day and get suckered into a race or forget or something stupid.

thank you for taking your time and helping me understand this better.

How quick is a question for the tuner to answer, but yes, you could hurt the engine if you go wot immediately after filling up with 91octame from E85.

What is a safe amount of time ... ?

How much is this package and what does it add to the jeep? I'm in California too
https://www.livernoismotorsports.com/product/LPP0116354

this is what I got but swapped to the 3.05 upper pulley. I didn't want to be stuck on E85 only.
the way its set up for me is about 200 additional HP. the 200 numbers are from Scott's estimate I didn't dyno so dont really know but I believe it.
This set up worked best for me I trust Livernois has the best mail order tune. I do not know any Legit Mopar tuners only LS. If there is a legit Mopar tuner you know about you dont need this package and can probably do the same cheaper.

You really think only half the people blocked him?? I guess the rest don’t know how yet.
LMAO only half blocked him cuz the other half want to laugh at him. I personally want to see if he ever goes to a meet. I WILL with zero doubt slap him like the lil girl he is.

^^^ Thought this was a grown adult thread?!? :wink2:

TLDNR - Wait for your fuel to mix for an hour of driving or so.

Anyway, for the sake of forum merit, back to your question: How long will the tune take to adjust?

The answer is "immediately" the tune will make the timing adjustments in milliseconds based on the content sensor. The problem that you'll run into however is that the fuel in the tank has to mix with the fuel in the lines and the rest of the system so the "reading" of the ethanol content will cause an immediate timing manipulation. If you have a readout of 85% ethanol (hypothetically speaking) after filling up because the pumps drew from the new gas before the mixing has happened and your timing is consequently advanced but then the pumps draw some fuel that is, say 30%, then during a WOT pull with the engine operating at 14,000 throws per cylinder per second I don't think I would trust the computer to pull timing fast enough to account for change as it only takes one instance of knock to throw a rod. Most serialization and propagation delay in modern computer systems is in the low milliseconds, but using simple math you would likely favor caution after a new fill up since a single throw at redline only takes 71 MICROseconds.

Hope this provides some insight!

There is no “content sensor” with these tunes.

The content is calculated at the O2 sensor, after the fuel is burned. So theoretically, your E85 tankful tune and timing will be running with 91 octane running thru the rails and out the injectors.

Good to know! In that case definitely wait for around a 1/4 tank I would say.

^^^Better wear red, cuz he’s “the bloodiest” lols

I really wish there was a fuel sensor but according to my Chevy guy, only GM does it that way. Apparently all GM vehicles already have flex tune built into the software, it just needs to be turned on and then some tuning after you add his proprietary hardware.

Scott says approx 30 miles for the tune to adjust. so the first 30 miles after every new tank I should not go full WOT?
I have had plenty of cars with SC and all modded (first with E85) has this always been a issue and not talked about so much or am I just reading way to much into this? is bad fuel a rare thing and I just happened to get E85 when its talked about most?
Thank you also for helping me understand this more it really is appreciated.

Livernois is the only tuning company I've heard mention bad fuel. Maybe it's much more prevelant in the States but I can't say I've ever heard of bad fuel here in Australia.

I use an ethanol tester kit before putting it in the car to make sure. If it's no good, I just put regular pump fuel in.

I know trust me I am no bully, I have taught a few anti bulling MMA seminars for kids. This guy just talks so much smack from the safety of his computer/phone and got to me.
we re all here because of the TH some of you guys know lot about E85 or tuning in general and instead of making fun of someone like me asking silly to you questions you took the time to try and help me. ThawMike could of lit you up for the "content sensor" comments but he didnt he just explained what he knew. thats the way we all should be like, I never understood the smack talking on the net. this time he got to me and your right I shouldnt have played his game if I offended you my bad I def didnt mean to offend anyone well almost anyone.
Thank you again for your replys
