Drive by wire conversion to Drive by cable?

[ZED SLED]

The only way to do this properly would be to replace your LS engine with an L89 427 from 1967, complete with tri-power and distributor setup. That don't need no stinkin' computer.

As for the Mustang guy that couldn't cut his usual light, you simply need to adjust your launch. No different than if you've changed a suspension, driveline, or engine component. Plenty of guys in those cars can cut a quick light. To blame it on the DBW isn't a good defense.

I know some guys could get used to it and cut better lights, I was simply throwing out averages. I could not get used to the lag, I needed the driver mod lol.

in the 04 on sportsman tree, I would hit the throttle when the last amber is lit. With my 07 on a sportsman, I had to hit the throttle inbetween the second amber going off and third amber lighting up to cut a decent light. more seat time would have helped for sure. But I I know if I could do back to back to passes I could cut better lights in a cable throttle then wire

I personally HATE the DBW! I don't lift on shifts, and I can hear the TB closing the moment the clutch pedal is depressed (there's a switch at the top, that also controls the cruise control turning off). I can hit the next gear and be out of the clutch before the TB opens back up, which then lurches the car. It's even more noticeable now that I have gears in the back. I miss the days of wide-open, full-throttle power shifts!

bump from the past...

I will be running a drive by cable in my 70 GTO with the LS3... I have all the 2004 GTO stuff... LS1 computer and harness and 2004 GTO interior.

I hear the Challenger guys complaining about the decal and accel of drive by wire...

The swap isn't pretty, but I had a 2004 GTO as a donor...

If you were to remove the gas pedal on DBW systems, which has about 10 wires in a harness that plugs into a harness that goes to your ECM, and replace it with one that uses a cable, you will have check engine lights all over the place and an engine that may not even start. The gas pedal in your car now is actually an electronic potentiometer, like a volume knob on modern stereos. As you press your foot down, it takes the input voltage from the ECM and increases it. The difference in voltages is what the ECM uses to increase timing, fuel/air delivery, and everything else.

It's really completely computer controlled. You cannot operate your engine without the DBW gas pedal installed.

In other words this does not make a good post apocalyptic dooms day get around vehicle, need an old carburetor '69 for that. A 5th gen Mad Max will not be riding around in

The throttle response is there when you need it. It would just smoke off the tires all day if it had a cable throttle and no traction control.

You want to rev your engine at stoplights and stuff, well the ECM knows that isn't necessary so it's not quick on the throttle response when you try to do that. Ask your tuner there are probably some settings they can adjust to speed up the delay a little bit.

Yes that is true but just because you have it to the floor does not mean the butterfly is wide open. The ecm has total control over the throttle servo motor. The system regulates airflow automatically when you tell it to do something the engine doesn't need, such as being WOT at 2000 rpm or tapping on your gas pedal, dancing on your gas pedal there will always be lag. They are programmed to take your foot input as a suggestion. Most of the time it is doing exactly what you tell it to do though if you are driving the car correctly. This system along with the ECM also operates the cruise control function.
