That's how it is in Seattle (and many other places in the US), too - E10 also requires a richer mixture for full power because its stoichiometric ratios are lower.

This is why custom tuning has to involve a feedback process of datalogging, to be sure the tune is optimized for a given fuel quality, for a given engine's build, for a given, unique engine, and for a given operating environment.

Thank you for that Vince... BTW, your stuff is at at top of the V6 "Fast List"! Now, if you could just find another tenth in the tune somewhere....

This is a great point. Every state sells some E10. Problem is some states do not require pump labeling (Indiana), others only require labeling above 1-2%, while the majority of states require it (WA up to 10%, IL 1% or higher). Max is 10%. E85 is a flex fuel, and is regulated differently. The equivalence ratios are very close to gas, so ball-parking the AFR's is fairly straight forward. For consistency's sake, if you're state requires labeling, just make sure it reads "WITH 10% Ethanol" and not "Contains UP TO 10% Ethanol". The "up to" blends are all over the map between 1-10%.

Precisely why Kent will be taking an EZ Flash cable home for further refinement of the tune.

Guess I'm the first "production" car tune

I've been running 91 octane in my logs im sending Vince. Since day one, I noticed the feel of the car is better with 91 than 87.

Awesome! I guess I'll need to tune for the higher octane, E10 blend. It's also, on average, $.05 cheaper per gallon then straight gas 87.

Beauwulf, I'm closing in on your fast v6! I've done a best, unofficial of 14.22 @ 102mph. Maybe the tune, LTs , hi flows and possibly a CAI will get me there! Then I've gotta go find a track and make it official! My times are on my DashHawk.

Now, i've never tested on the dyno or the track... but I think I will try it this spring at the track and see what happens!

I know I've said that it was a waste of money in other threads to get the higher octane fuel, but it's good to see that we have real data now to prove that it's not a waste. I know I will be using higher octane fuel from now on. Thanks for providing us that data.

Any engine capable of adapting to varying quality/octane will show a marked improvement in tractability and mileage via KR and enhanced timing, with a slight increase in power. Depends on the actual improvement made when moving to the higher octane. Just keep in mind the E10 issues described above.

But, wasn't his after tune dyno 272 hp? Ide call that a definate increase over stock HP.

But the car WASN'T stock... it had an aftermarket CAI which according to Vince's post was causing the car to run lean. When they dyno'd the car without the tune it was only at 248 RWHP... that's what my car dyno'd at 100% stock... so it would appear the aftermarket CAI wasn't helping the car, in fact it might actually have been hurting it... Vince straightened out the A/F and that's when they seen the nice gain!

So the thing is on a stock car the A/F is fine and there really isn't anything to "fix" to get any noticeable gains... which is why Vince posted what he did... that a tune for this car is not for the masses but rather for guys who have modded there cars and need some tweaking..

So are you expecting somewhere in the 280s for your car when you get your cai installed?

[ROD1]

This is the Dyno for Hanover fist. Went to Vince untuned with a CIA, ran a stock tune dyno then a dyno with the trifecta tune. Most impressive gains.Note how the CAI took out the hp dip from 5000-5500 rpm even before the tune.

[esperman]

Rod, what other mods do you have other than the Airaid? Sorry it you already had posted that info.

how does the car respond now that you've been running this tune?

[BLK2LT]

I have ordered a trifecta tune as of two days ago and was wondering if i should pay to keep the ez flash cable so that i can do data logs or just get the tune done send it back and then wait and see if there will be anymore available options to tune on our v6's?
Anybody's thought?
Also i will be happy to inform yall of my results as soon as i do my tune. I have JBA shorties and a G5CR CAI.
Thanks,
Mark
