Convert DBW to wired throttle... Anyone done it, is it possible?

[VAG-Slag]

Probably sounds mental to most of you but I've always missed the crisp feel and direct connection a good old fashioned wired throttle gives...

Has anyone ever converted to wired throttle?

Besides obviously having to feed a wire/change the pedal etc are you likely to encounter problems mapping me7 to work with a wired throttle or will the TPS take care of that?

Would be interested to know, if it's not too overly complicated would consider giving it a bash...

Might be worth mentioning I have a face lift A3 (AUM), any thoughts/experiences/input welcome...

Thanks!

Doesn't work that way.. ME7 controls the throttle based on load request... fuelling strategies and timing is based on that too...

If you want a cable throttle then go standalone

Ah right, that's pretty much along the lines of the answer I was expecting... Damn ME7!

Deffo not worth going down the route of stand alone in my case, was more just curious than anything else. . . The DBW will do just fine for now!

Cheers Tuffty, always on hand! lol

map throttle linear then ??

Bill, are you saying this is a way you could map ME7 to work with a wired throttle? If so would there be any drawbacks to doing this?

No... what he means is you linearise the throttle maps so it feels more like a cable throttle

Pedal maps have a peaky bit so you get high load request for a small amount of throttle movement... linearising this makes the throttle pedal feel more one to one with the throttle body...

You are still not 100% in control of the throttle plate of course as the ECU will open it to suit its needs but feels nicer to drive with

Oh right, I understand... I think :-/

Bill, I might have a chat with you about this when I come back for mapping 2.0

Why is this not a standard thing on a map then?.. Sorry for all the questions! Don't really know much about mapping as you can see!

you can make its "drive" quite different with the maps in me7..

the pedal is a "torque request" device.. asks for a % of full torque for % pedal movement.
std pedal map is anything but linear in its torque requests.

Many people, having owned their cars for a long time, don't like the linear throttle maps intially when they're loaded on, saying it makes the car feel very strange. I guess it's because you have to use a little more throttle to get the same initial reaction compared to stock pedal mapping.

I'd imagine that's why it's not done as standard unless it's actually requested

 

[badger5]

all down to degree I guess. Some maps exaggerate the dbw effort, so it "feels" faster, lol, whilst making no power difference what so ever.

 

[VAG-Slag]

Mmmmm, so by the sounds of things a linear map won't necessarily be any more "responsive" as such...

Ah well, thanks for taking the time to explain Bill! . . Will be giving you a shout when I've built my new engine a swapped it over

 

[badger5]

response can be whatever you want it to be..
way more pro's of dbw on wideband than downsides imho
