Probably more advanced timing. At least we know there are more ponies to squeeze out of her.Prometheus said:i apologize guys, seems quad t may be right. compression ratios are the same however in the infiniti qx56 it demands premium fuel only. it must be a ecu thing... :teethmast
Who you callin' chunkie? lol:rofl:tortuga said:sneaky, compression ratio is raised in the armada to increase torque and horsepower to COMPENSATE for the armada chunkiness. its all power to weight ratio relativity crap. :domohit:

Why would you use premium? Our trucks run best on 87 octane.pi3yeargrad said:darnit...can I get mine fixed to want premium and work best with premium..that usually all I use anyway...

Now, if you have changed your timing or the ECU then I understand your decision:3eyes:
Yea, My Titan seems to have more snap with 89 or higher octane...i wonder if the ECU auto compensatespi3yeargrad said:gotten this before BUT Im used to the premium just cuz my trans am, well thats all itd take and people say "ye right" BUT I PERSONALLY feel my truck actually kick with premium and not with regular...it even boggs down with regular and not with premium...it could be that the premium gas is just cleaner around here and reg is real dirty but who knows...I like it though and thats what I use so is there anyway to make my truck "run better with premium" since it "runs best on 87 octane"
This has been covered before. Consider doing a search. The difference is miniscule. So small that testing the same truck on different days accounts for that much difference. The Titan test and the Armada test were not done on the same day and probably not on the same dyno.SNEAKY said:why does the Armada have a higher torque rating? what can done to the titan to achieve the same numbers? is it ECU related or Intake/Exhaust related?
BTW we just click 12000 miles on ours, time to lay the hammer down :futwice: :teethmast
pi3year, if this is the case then I retract my previous statements.Armada said:The engines, the drive trains and ECU are identical. Premium fuel helps both vehicles the same way.
I posted the same thing somewhere else after a similar question was ask. Few peoples call me a B.S.er:rockonArmada said:I guess you all understand that our "smart ECU" is capable of advancing timing until it detects knock. That's why you get 10 extra horses in all Endurance engines (Titan, Armada, Infiniti) when running premium fuel as compared to regular.
This too has been covered in depth elsewhere here after extensive testing.
We were told on this site, a year or so ago that the ecu has a pre-set timeing setting. If it detects a knock, it would only retard the timeing, and when the knock was no longer detected it would go back to the factory setting, but it would not advance the timeing past the setting.Armada said:I guess you all understand that our "smart ECU" is capable of advancing timing until it detects knock.

Here is Juma's thread from a while back where he actually tested timing advance under load with different grades of gas.rholland said:We were told on this site, a year or so ago that the ecu has a pre-set timeing setting.

I ran 4 tanks of premium and saw no improvement on the street, gas mileage or performance that I could tell. I do agree that it might help at the dragstrip.
