converting s54 to throttle cable

[got psi]

DBW offers more precise control over everything than a throttle cable can.

The "feel" of the throttle cable is just friction and spring tension. You can emulate all of that. (hell, you can put the throttle pot at the end of a gunked up old cable with a rusty spring if you really want to.)

I said what I did because it showed that it was a technology some haven't used yet. DBW can be *faster* and *more responsive* than a cable. It can also offer more precise control.

I agree what you said BUT BMW hasn't figured it out what their customers want out of a drive by wire as far as I am concerned. I have been in a number of BMW's that have horrible throttle manners. ///J.T.///

Only reason I'd choose cable vs. DBW is troubleshooting. I'm running motec on my S54 which is capable of handling DBW but opted to keep the cable and use the Sunbelt system. I've seen problems w/ the DBW after being in the garage next to RJ Valentine's PTG F1 Air car. While I am sure it is great when working and when you have electrical engineers around, it could be overwhelming for an amateur driver/club racer. I'd definitely go ahead and buy the Sunbelt setup as the VAC setup has the most awkward hinge point and with a 5.5" clutch, makes leaving the pits a smoke show.

Why not get a real standalone that can handle DBW?

Did you read what I said before you quoted me? I am saying, get an ECU that can use the DBW, as its better.

okay guys, DBW isnt really an option. anybody else done the conversion without using the kit?

here's how i did mines, i took a e36 throttle body, cut off the pivot piece, took off the bracket that holds the gas cable, a piece off plate 4" x 4", the gas cable is actually from a older 5 series (shorter), the pedal feel is like stock, i also have a pedal stop at the gas pedal not to over stress the the linkage, everything is adjustable till u get the pivot angle that give u full throttle, drill holes bolt down, this works for me , total cost, a gas cable if yours is too long,

[lifeiskaos]

that is EXACTLY what i'm looking for. thank you so much

how is the response?

like stock, remember to have some kind of throttle stop under the gas pedal, adjust it to full throttle, so u don't stress the linkage assy at full throttle,

i believe you sir have just saved me $400. that looks awesome.

got a build thread somewhere? that there is a monster e30

servo motor = throttle lag = fail and gettin passed by the competitor

Incorrect, try again



It all comes down to the tune. From factory the drive-by-wire is rediculous because it "adapts" to the driver so it's always changing its responsiveness. Throw a decent standalone on that bish and it'll be all good.

Deagle on this forum would have a lot more input on this since he's actually working on a BMW Motorsport (or PTG, can't remember) S54. And what do you know...no cables

[Mr Deagle]

Well Mazur, there are 11 cables. I like to call them conductors. All those, some digital processing by motec, and you get a freaking touchy throttle pedal. I doubt that anybody who disses DBW can outrun a proper DBW setup.

this is going to be fun:

awwhh.. I was doing a little research on S54 throttle cable conversion and came across this thread. So many old-heads in here that use to post all the time! *sigh* memories.
