My cold starts are the same. FI might be the variable that is different for you however, it could also be a issue with the fuel system upgrades. A good tune would net you strong whp gains.
One thing that's nice is I have my tune files on the laptop and I can switch back to pump gas whenever I want. Another benefit from my tuner

If your going to do E85 you need to have your heads milled and ports cleaned up. You can run over 13.1 CR with E85 (105 octane) and make 30+ hp with the added CR. Believe it or not the EGT's actually gets cooler on E85 the higher CR you run.

Aren't there a few plastic parts that need to be replaced so you don't ruin the fuel system throughout the vehicle? I thought there were some parts that needed to be fitted to make a vehicle E85 capable..
I wish coskata and companies like it... would produce enough ethanol that we didn't need to import oil any longer..
If it didn't damage the vehicle and you could tune for it and produce the gains your showing......and it was available...I'd definitely be tuned for E85!
Thanks for the report...Something to look forward to for the future..

Ethanol has less energy in it per volume than gasoline. Nothing will ever change that.
You can be more efficient by upping compression or advancing timing to take advantage of the octane, but it will never overcome the difference in energy content of the two fluids. It's not even close.
"Ethanol is a dream and a dumb one" -Daniel Tosh. Yeah, we have a lot of land that can grow inedible corn, but all we are doing is employing a profession that should have ended a century ago. Ever drink a regular Coke or Pepsi and a throw-back or Mexican canned soda. Sugar tastes a million times better. We drink crappy soda because our government is run by lobbyists, not by anyone who is making decisions to benefit their constituents. Do you think the "Informant" was completely fiction? Nothing is completely fiction.
And in response to the last post. The amount of land it would take to create enough corn to fuel America's cars is larger than the surface area of the Unites States. So start tilling your yard and driving about a quarter as much as you do now and maybe we won't need oil anymore.

I personally think E85 is a very worth while mod. The only concern for anyone considering is availability of E85 in your area. In GA we have 14 stations and all are 20+ miles from me other than 1 that is in a direction I never travel. I'm itching to see what my H/C setup will do on E85 but I'm not driving out of my way to fill up on a regular basis. I also use the car for long trips so that becomes a drawback in my case as well.
Although boosted, the GTR guys are lovin' E85. I've heard in those applications they spool much faster and the tq gains are nuts.
For now I'm stuck with little ole 93 and envious of you MW folks in this regard.

Meth injection sees the same gains without taxing fuel pump and injectors. You run 93 (or 91 where its the max) on the hiway and such without reduced range.
Having done both mods a number of times to N/A cars, I like low end TQ with E85 but the 115 octane without E85 station hunting is great.
The downside is the meth can fail. Mr Big had a failure and 1 car I did had a pump failure. Meth has a test feature to see if its working plus an idiot light.
E85 has some debatable issues but if you can tune in the huge injectors it needs especially for FI, its a great mod.
The tune basically just chages the stoic to 9.76 and then you adjust the timing table. Meth is the same for WOT but it lowers IATS on FI cars. E85 burns cooler than gasoline.
As to cold starts, its exaggerated. I know first hand.
Both alky control and snow performance sell N/A meth kits. I think Charlie has had great success with the labonte meth kit.

The Labonte kit is pretty good from my perspective. But I have been recently told that there are some areas that leave something to be desired in my current setup, as well as the other available kits. So a fix to those shortcomings are currently in the works...

I could care less boss... It's legal to purchas and it nets more whp... Not looking past it any further than that. Hope the thread doesn't start to flood with commets like this.
I look forward to update my E85 conversion experince when I get back from vacation! Take care everyone!

E85 is awesome stuff, just tune the car for it and away you go. The FI guys love it for sure, as you can wind up the boost, and no worry so much about detonation.
I'll be seriously looking at it for mine, and researching that there's the pumps available for me to use it consistently, or have an ECU that I can easily switch between E85 and 93 as needed.
Its interesting to see people modify throttle bodies, MAF sensors etc etc, when they aren't producing enough horsepower to warrant it, but dont do something thats as simple as using a different pump at the gas station.

I've never heard of long term effects. Older car's maybe, and I mean around 2000 and earlier maybe would have an issue, but anything 1/2 modern would use quality parts ( fuel lines, injectors etc etc ) that wouldn't have issues with E85.
Just tune to make the most of it, else you are really wasting your time.

Project CTS-V Stinger R is our E85 setup build with our Stinger Ram Air Induction system and LPE pulleys, Katech intercooler, ZR1 cam, Katech titanium retainers and PSI springs, FAST injectors, and E85 fuel.
This pull was abbreviated due to injector sizing. 3200 rpm to 5300 rpm:
First pull show the increase from the stock CTS-V. The pull was aborted when we ran out of injector (65lb/hr too small) at 5300 rpm. 6500 is the power shut-off so the 15 PSI will likely be 17 PSI at 6500 rpm tomorrow.
The is an automatic with bone stock exhaust. No headers, no change in mufflers.
770 HP should be the flywheel horsepower. Amazing motors, especially with cast pistons.
We have all of our vehicles on an E85 diet including our 2950 lbs 700 HP Z06. Over two years on E85 and still lovin it!
You'll love the fuel and the cost.

Car is running great and still no ill side effects. I am doing a data log this week to see if anything needs to be adjusted.
