So I gained 12 RWHP just by doing the HEAT MOD! LOL!

Yup.. I noticed that too.. here's just one of another example of back to back run on E85 running 40* of total timing LOL yes 40! Gained 6hp by the end of 3rd run. If you also ever did some hard twisty back road runs you will also notice the harder you push the car the peppier and stronger the car will pull. The nature of our LLT is that it likes to get heated.

I'm glad that we have some great guys on this thread! Knowledge will only get us further along.

Well I tried updating the tuner and my car wasn't supported, so now the waiting game I guess for them to write a tune. Sucks this has turned out like this.

[cowboy1948]

Ok here it is.
They sent me another down load for the turner.
Uploaded it to the car, and programmed it with these three,
regular fuel, airaid intake no insert, transmission firmness set to 75%.
Started car, idle rough and fluxed between 700-300 RPMs.
Reved it up to 2000 RPMs it smoothed out.
Let off the gas smoothed out at approx 700 RPMs.
put her in sports mode, idea was smooth, gave it the gas, and she bucked and cough and stalled but stayed running, got here back to the house. Returned it to stock, starts and drives ok.
Emailed hypertech all the info.

Later in the day, they sent me another update.
Down loaded it to turner, then uploaded to car only using the three paramiters that I used above.
started it up, rought iead around 700 Rpms, but no shacking like before.
then it smoothed out. Reved it up to 2000 RPMs runs smooth. Back off to iead, running smooth at 700.
Went for drive, Started slow like i always do, running smooth, gave it some gas as it reved passed 2000 RPMs it just took off. I could fell the shifting was a lot firmer and faster.
Service stability icon came on, along with the icons telling you that the traction control and skid control were off.
went back to the house all was good.
shut her off, got my odbII reader and cleared the stability, traction control and skid cotron icons.
Started it up flux for about 1.5 sec then smoothed out at 700 RPMs.
Did that 5 times all the same. Reved to 2000 nice and smoothed.
I have emailed hypertech all this,
I LL take her out on the freeway tomarrow morning and then let you and
Hypertech knows.
By what I felt today, it pulled stronger and shifted faster. That was what my butt dyno was telling me.
Not going to play with the RPMs or shift points till this part looks ok.
I LL fell her up with premium fuel tomarrow morring and reset that.
Any one else have anything.

Sounds kind of sketchy and im just worried for mine lol, but ill keep my fingers crossed! hopefully you get yours fully settled and the car runs 100% but for now its good to hear at least the cars feels a bit stronger!

I gotta ask this again since no one did last time , is premium fuel to you guys 93 octane??? (im in canada) i usually run 91(no ethanol) from shell the only higher octane is sunoco 94(it has up to 15% ethanol) ... just wondering what would be better!

Run the highest octane you can find. 15% ethanol is not going to harm anything. Ethanol actually has higher octane values than gas. Higher the octane the less susceptible your engine will be to kr and detonation.

[SIXJAK]

I could be imagining things but I've found a gas station which sell pure 91 (no ethanol) I gotta sy my car really seems to like it. It seems to feel smoother and quicker.

[ibmrs]

ethanol equals less HP, by a lot. your car will love the pure gas much more than the octane difference between 91 and 93, you'll get much better gas mileage with the pure gas too.

My truck (02 avalanche) hates 10% ethanol (non e85 vehicle). 20% less gas mileage/power. So net effect is i burn 10% more fossil fuel now that the government has enforced the ethanol mandate than when i could buy pure gas. BRILLIANT.

I can't say I would feel completely happy with that... It doesn't sound smooth at all, and having to rev it to smooth it out? When I get my update and it's anything like this, or does not seem like all the bugs are worked out by then I'm sending it back. Hoping for the best.

20% less power and mileage with 10% ethanol It make sense that ethanol will give you less mpg due to having less energy mass than gasoline but I don't think 10% will be significant enough to notice 20% loss in mpg or power. When I was running nearly 100% ethanol(e95) I was only seeing about 25-35% drop in mpg and I was not driving her like a granny or a speed racer, and most of us know the power it can make on ethanol although it has to be tuned and not to mention, every dyno run I i've done so far on gas tune has been on 93 with 10% ethanol with no ill effect.

Not that I don't believe you but maybe its a 2002 avalanche thing

Did you get your updates yet?

Sorry about the off topic here but,

Ethanol does decrease mileage some as you stated. I can see about a 1.5 mpg drop in mileage if I run 10% ethanol in the Camaro. Normally I average about 22 mpg on non ethanol and 20.5 on 10% ethanol. Many tests have shown that E85 will result in a 15% drop in mileage over conventional gasoline. My findings are even with E10 I am seeing a 7% drop in the Camaro, my old Silverado and even my Harley. Regular gasoline has 114000 btu/gal, E100 ethanol has 76100 btu/gal and E10 has 110210 btu/gal, so theoretically E10 is about 3.5% less efficient. But in practice, I am seeing twice that loss in efficiency.

As bmorecam pointed out, you can actually make more power with E100/E85 type fuels IF the engine is built to take advantage of the increased octane rating of ethanol over gasoline. To do this you have to increase the compression ratio and amount of fuel supplied. Flex Fuel vehicles have to be able to run on regular gas and E85 and therefore can not increase the compression ratio to take advantage of the increased power potential of ethanol. All they do is advance the spark which will only give you a small gain (like bmorecam showed in his dyno of E85 earlier). Variable valve timing has the advantage of being able to change the IVC timing and increase cylinder pressure in the lower rpm range to maximize lower rpm hp but then change that timing to maximize the upper rpm power as the rpms climb. This is one of the reasons why you see a very nice wide torque curve on our little 3.6L’s. However, if you specifically built the engine to ONLY run ethanol, you would see the real potential like racer have for years. On E100 you would need to add 1.5 times as much fuel versus regular gasoline, but combine that with the increased compression ratio and you make more power, just less efficiently.

Back on topic. It sounds like Hypertech is making gains and with the more they sell and fine tune the better the updates will be for all. So do you think that each time they create an update is it global to all who update their tuners or are they buildign custom updates for each owner at this point?

[Victoryred69]

Soooooooo, would the verdict be run 94 to see optimum gains ? :P

Shu, you would only hope to think that if there are making some progress with certian cars they have to add the patch to the tuners brain to in a way like scan through each ecm and if they have different codes or whatever , to match it up unlock it and allow it to be used to full potential on any camaro v6 but it only seems there's new cases of cars that haven't been thought of which they are making last minute tunes or codes so to say for.

As I said earlier I'm crossing my fingers to see if mines going to work first shot !

Nope, not yet. If my cal number is farther off than yours they are writing one. I tried updating it but nothings been made yet and no email.

I filled up with 93 octane yesterday, today it kicked in. I notice a difference since I usually run regular. Ive tried it before and it's well worth it. If this freaking tune can pull through it should all work very well.
