also the size of the throttle body will have an effect on throttle response. the BMW M3 other than its not a mustang was one of the finest automobiles ive ever driven. if i could only get over 49,000 sticker. and throttle was NOW. im sure for a sports car ford will get it straight and the throttle response will be good. a good ETC will be faster than a cable setup

 

I certainly hope so. The lag on my Mazda 6 is intermittent but occurs often enough to be a PITA. I'm really getting pumped about the new Stang and I'm looking to possibly replace the 6 in late '05/early '06.

 

An electronic throttle shouldn't be troublesome

I have heard that many people don't like electronic controlled brakes, as they don't relay the same feel as physically linked lines. Just read any reviews on the SL500 and you hear of the belly aching...whereas I haven't heard much bad press about the electronic throttles

 

None of those cars are Fords. The Mazda 6 (which I currently drive) uses a Duratec V6 and a Ford PCM and it suffers from slight throttle lag on both automatics AND manual trannies. [/b][/quote]
The Ford engineer who was at Foxboro used to work on the Lincoln LS and is very familiar with it. He told me that although the 05 Stang uses essentially the same PCM & ETC setup and same auto trannie, the Mustang vehicle calibration engineers have spend a huge amount of time tuning the PCM code and calibration parameters. He said the the responsiveness of both the V8 engine and the auto trannie were great and were improved over the LS.

Sounds like some of you are worrying about nothing.

 

I own a Tribute too, and it seems to be working fine so far.

Maybe it's just a problem particular to the 6 and not all Mazdas (or Fords). It's good to hear that the engineers have been paying attention to throttle response on the Mustang.

 

the electronice throtles I have tried worked well, but they wernt ford ones. So I dont have much imput on the 05 stang throtle

 

I have a 2003 Jaguar X-type with the 3.0 and throttle by wire. This system is made by Ford (the engine is built in Cleveland, Oh). Under normal driving I can't tell the difference but some times when I floor it, there is a hesitation. Mine is an automatic and it is not the transmission causing the hesitation. One of the reasons they went to it was because it can better operate the traction control. Maybe with traction control off, we won't notice any difference. Time will tell.

 

That's exactly what happens with the Mazda 6. The lag problem is intermittent, occurs with both the auto and manual, and seems to get better when the TCS is turned off. I hope they've improved the ETC and TCS in the Mustang.

 

I just got my 2003 Lincoln LS updated to the latest software. Engine response and trannie shifting are significantly improved. The 05 Stang will have newer software. I think you guys are worrying about nothing.

 

the underlying reason for drive by wire is for emmissions. keeping this in mind, it's easy to understand that ALL drive by wire system will have a delay or lag under certain conditions. this is EXACTLY what the dbw is designed to do. in order to meet fed requirments, especially when the engine has not reached operating temps, the computer controlling the input from the throttle pedal will NOT allow you to "floor" the pedal and expect full throttle acceleration...won't happen on ANY car...not under those conditions...this is the future of engine management systems, jackg 90seville 94k

 

All this talk about PCMs, safety protocols, and tuning...

Perhaps it needs a more powerful throttle motor? I mean, the thing's rather rinky dink lookin...

Just something that popped into my head. I must be nuts.

 

Electric motors are enoumously powerfull. You wouldnt believe the phenominal power of electric motors in modern RC aircraft, or how much torque an 8hp elec motor can produce in a hybrid(more then 4 times its hp rating easilly).

exactly. Especially a starter motor. Man those things have power to start your car in a sec. More torque than a honda

Like I said before, cars tend to evolve not the opposite.

 

justgreat, you're right about this. The first time I take off when it's cold, it hesitates and surges BAD. I figured it was just what you were saying. Earlier I was referring to normal driving with the car warmed up. I hope someone high up figures out emissions should never be put ahead of throttle response. My family's safety is more important than a few seconds of bad emissions.

 

Allow me to repeat myself:

Don't Worry About It

I think this will turn out to be a non-issue. Ford certainly is very well aware of the compaints involving electronic throttle. That last thing they'd want is a poorly responding stang. Mustang drivers are purists, they'd rather have cables etc. that allow them to connect with and feel the car. You make a substitution, it'd better not deminish that connection.

 

Yea Ford offical releases have harped on how fast the new computer system is in the Stang. Also the electronic control allows them to vary the throttle position at altitude so half throttle at 1000' will feel the same as half throttle at 5000'
