I would have to challange your "racing" the dodge hemi. The truck has 345 hp, you have 305hp thats if you have the new Titan and even with your flowmasters you MIGHT have 315. Are you sure the truck was racing you? I really want to race a Titan, I have a 1997 Ford F-150 Lariat 5.4L V8 with all sorts of mods, K&N cold air intake w/filter, "superchip" and flowmaster duel exhaust 40 series. But you might have because even I could keep up with it untill we hit 50 mph then he was gone, but i have a lot of mods on my truck..

did all the "mods" you performed help or hurt your gas milege?
 
I'd sure like to get the milege printed on the window sticker of my '04 F150. Can't seem to break 15 even while hwy driving at 65 mph

if you are a truck guy, you should know that HP #'s mean almost as much to acceleration as cupholders do.
 
torque is the key, and the nissan has more torque at lower RPM than all others.
 
on top of that, the fact that its a 5-speed tranny with drive-by-wire acceleration gets the titan a solid half-length lead in a race before the dodge even gets off the line.

That 1/2 car-length lead is not due to the fact that the Dodge doesn't have a 5-speed transmission and drive-by-wire, because it does. Actually, the gasoline RAMs have a 6-speed automatic transmission (545RFE). Dusty

Drive by wire won't give you an advantage of time or speed, it actually will give you a half-second of hesitation over direct wire response, so it's not that.

and you smoked your breakfast this morning??? lol.
 
electronic throttle control has significantly faster response from the pedal over cable-actuation.

I think NV's correct.
 
The fastest a throttle can open on a direct cable system is only limited by the operator's human motor control. If we assume that drive-by-wire is faster, it still cannot be faster than the operator's foot.
 
On drive-by-wire systems the throttle is opened by a 4-pole stepper motor. Any computer lag time issues aside, these typically have a 50-150 millisecond reaction time, unless you're talking about a very expensive motor. The computer circuit that operates the throttle motor will have a reaction speed as well. This is typically limited by whatever clock frequency (speed) is plus the buffer (op. amp.). It's very likely that a drive-by-wire system could have as much as 300 ms delay, even in the best of circuits.
 
Three-hundred milliseconds would not necessarily be noticeable to the average driver. But it is very doubtful that drive-by-wire could ever be as fast as a direct cable operated throttle, in my opinion.

but dont forget that slack that forms in a cable, along with the imprecise nature of a mechanical throttle. the ETC has no lag in a cable, and the only lag time is in the computation for the right mixture, which you dont get in the mechanical ones...therefore, you get the "throttle lag".
 
this throttle lag is extremely apparent to me on non-ETC vehicles now that i know the difference.
 
drive the ford, then drive the nissan, and you will see the difference.

I'm taking my anecdotal evidence from the complaints on the Lexus boards, where the drivers are complaining about the "hesitation" in the throttle response caused by the drive by wire in the new models over the older ones. It seems noticeable to them. Maybe Nissan has a more expensive motor? Doubt it though.
