#101 of 143 Drive by wire throttle by fitluver Apr 03, 2007 (7:17 pm)
Does anyone here know exactly how this works in an MT?   I hear a sort of revving at certain points in my commute and I do not know if it has something to do with the drive by wire throttle.   I do not know much about it, and any explaination is useful.   I am used to a car that is NOT run by a computer, or minimally so, so this is a new thing for me. Never had ABS either.   I notice a sort of revving sound during certain points in travel, mainly going from one type of road surface to another. (ie gravel to road, road to gravel, road to grated bridge and back etc.)   Does the engine or transmission "adjust itself" when you hit different types of road surfaces?   Help anyone!

Replying to: fitluver (Mar 17, 2007 7:59 am) You realize dont you that you arent supposed to drive a car in cruise while traveling thru traffic, right?   Where did you ever hear that one?

Replying to: bobw3 (Apr 04, 2007 4:04 am) You realize dont you that you arent supposed to drive a car in cruise while traveling thru traffic, right?    Where did you ever hear that one?   That little warning box on page 127 with the bright orange warning sign that says "use the cruise control only when travelling on open highways in good weather".   I realize that is vague but in previous cars also it was spelled out not to use cruise in heavy traffic.   Part of the reason being that if you use the cruise to slow down, it does not light the brake light and someone can easily come up on you too fast because they do not know you disengaged. I would imagine hitting cancel would also not engage the brake light.   And we all already know not to use it on wet roads, right?

Replying to: fitluver (Apr 04, 2007 6:19 pm) I use my cruise all the time. Even in town. Makes it easy to do the speed limit if you are impaired in any way. One less thing to worry about. Not that I would condone that sort of behavior. When I take my foot the gas, my brake lights don't come on. I also run with scissors and play with BB Gun's.

Replying to: nordo (Apr 06, 2007 7:21 pm) I use my cruise in the suburbs. In fact, in can be safer because in an emergency, I don't have to move my foot from the gas to the brake, but just press the brake. So I'm saving a fraction of a second.

Replying to: fitluver (Apr 03, 2007 7:17 pm) "Throttle by wire" means that instead of a mechanical connection between the pedal and engine valves, like a cable, the signal is measured electronically (with sensors) and then relayed via a microchip to ecu and to the engine. Supposedly this is more efficient because the computer can synthesize various data and control the engine in the best way. I'm not sure what noise you're hearing, it's probably not connected to the throttle. Could it be the tires? The Fit's a pretty noisy car. The throttle by wire uses DC motors to move the valves, so maybe that's what you're hearing. The engine doesn't adjust to the type of road per se, but the computer synthesizes throttle, rpm, gear, and other factors, so perhaps a different road surface changes the traction and requires more engine.

It revs, then settles once i am "on solid ground" so to speak.   It MIGHT even do it after making a left or right at a regular stop, when I straighten wheel up to drive but I haven't paid THAT close attention.   Can someone else pay close attention to their MT at times like these? (ie solid turns such as parking/pulling out of a parking spot, driveway etc?)   Let me know?   I have a friend that just bought same car and I might ask to borrow her car for a quickie. It might give me peace of mind.
#109 of 143 Automatic trans revving by jacinta Oct 22, 2007 (10:09 am)
I can drive both an AT and MT. I bought an AT sport. I feel like it is sluggish after it shift into third. When I press on the gas it revvs and the fuel meter drops. I am only getting 28 mpg. Should I take it to the dealer?
#110 of 143 Rought Shift between 1st and 2nd by jtbryant12 Nov 20, 2007 (9:04 pm)
I just bought an AT Sport a week ago. While stuck in bumper to bumper traffic on the highway, the car seemed to shift a bit rough going from first to second and then back to first. My top speed (~15-20mph) seemed to be at the shift point but it still felt real jerky to me. Has anyone else experienced this? I'm going to mention it to my dealer when I get a chance but just wanted to know if this was common.
