New Fuel system on 2010&2011

[luillo]

I am not sure how technical is my question but if i remeber good the 2010 and 2011 knock sensor is tune to use 87 or 91 fuel?

Who know about the Fuel system on these cars??? I ask because the dealer give me the car with 87 and i am planing to use 91 but i dont know if that will give me any benefit at all.

Is the car going to run better, like take less timing or it doesn't matter at all and the only difference comes when i get a mail or custom tune done in the car???

The fuel system on the 2010 is the same as the 05-09. Returnless with a single pump and single module. The 2011 however is an entirely new system and is a mechnical returnless system with a single pump. I had Justin Fore from Fore Precision Works at our facility today taking a closer look at what the stock system is comprised of as well as test fitting a new billet hat that houses up to 3 GS342 walbro pumps. I'll have a video posted up tomorrow speaking about the system.

As far as tuning goes these cars have adaptive octane. So even if the tuner uses a timing table based on 93 octane if the vehicles knock sensors notice and detonation/knock it will pull timing. It works the other way as well. If you put real good fuel in such as C16 and the knock sensors don't see anything negative the car will continue to add timing essentially making the car faster and faster as it learns.

If you have any other questions about getting a custom tune for your 2011 give us a call. All of our tuning is done by Jon Lund so you can be sure you're getting the best.

Thanks, Jared

thanks i will i just need to unlock my tuner and i will like a CAI too.

So if i go to the track i should use 91 anyway right. thanks..

How much HP should i spect from CAI and Tune, i know these questions is kind of open for dicution but can you give me an estimate???

so, if you were say using torco concentrate race gas to get you 100 unleaded, the car should run faster??

 

[Twinscrewgt]

Yes. Potentially the car could make more power and in theory run quicker.

If MBT timing cannot be reached on 91 or 93 octane, then the additional octane would allow for more power to be added via the adaptive spark.

The rest of the info you posted is very good to know! Thanks for explaining it to us.

 

[Jared@Lethal]

Yes. As mentioned below if the adaptive octane feature doesn't sense any knock it will continue to add timing and the car will make more power. Our tuner told us about a 2011 that ran C16. He said the car kept getting faster and faster each run as it loved the high octane.

If MBT timing cannot be reached on 91 or 93 octane, then the additional octane would allow for more power to be added via the adaptive spark.

Exactly.

Are we saying that if we put in gas that is higher than 91 it will just adjust timing and increase power? How far does this scale? I mean, at the track, we can put 100 in there and we'd actually see a difference or would it be a waste?

i think it's more if you put in better gas, and add more timing, if it doesn't pick up detonation, it won't pull timing

Maybe it's time to bring up octane boosters

"One bottle is enough to make 10 gallons of 96.6 octane out of 93"

Pretty good results

Torco kills that, 10 gallons of 91 is 102 5 gallons of 93 is 105!!!!!

Yes I run the Torco race fuel accelerator at the track all the time now when I can not get 104 unleaded. It works great and I am able to add 8 degrees timing to the car above the 93 octane tune and my a/f is still only 11.7.

 

[2011CS]

"Torco advertises that it can raise 93 pump to 107 when used in the highest concentrations. Tested in the highest recommended mixture we saw an AKI of ~99 though a secondary testing method. 8 full points from 107 if you assume Torco was implying 107 AKI and not 107 RON. This would mean it was raising 97RON to 107 RON. If you standardize the results on AKI you will see that 107RON is actually fairly close to 99AKI. This is much better than you could hope for with the more common additives such as with xylene or Tulene. If you assume $3.00 per gallon of 93AKI pump and $17.50 for a can of the Accelerator that works out to $6.50 a gallon. With race fuel such as VP and Sunoco in the $5.00 neighborhood this does not make since."

That torco? There is a big difference between 107 AKI and 107 RON

 

[navbtcret]

If you buy the torco in the 5 gallon can it comes out to quite a bit less than that. For someone like me who drives their car several hundred miles to the track frequently, running race gas all the time is not an option but using the torco at the track is.

I also picked up around 40 rwhp from it on the dyno so it works.

 

[2011CS]

Just making sure and not trying to argue.

The lucas per equal mix shows higher gains is all.

You are correct. If you put in better fuel and the car doesn't sense any knock/detonation the computer will add timing by itself and make more power.

i think it's more if you put in better gas, and add more timing, if it doesn't pick up detonation, it won't pull timing

I've been told by our tuner that the car will add timing by itself if no knock is recognized by the computer. The same way if you put in crap gas and the car senses knock it will pull timing.

i would think the factory programming would have it commanded to a certain extent though
