      Wanna do a pedal box, and there is a DBW version but its almost twice the price. I know obd2 cars can be converted to DBC. Buddy did it in his VR race car.

      Question is can DBW be disabled through vagcom like his mk4 was?

      Also doing this for throttle response, along with R8 coil packs.

      I forgot.. Nobody does anything to their cars outside of buying dope bolt ons. Nvm took care of it, and it can be done rather easily.

      agreed.

      Let me start by saying, WHY?
      i have a VERY good throttle response, almost instantaneous.
      Keeping the oem system is good as it helps tuners, and keeps the car "simple".

      Secondly,
      have you ever done anything yourself?
      tried anything new?

      by all means, dont complain and go ahead and do it.

      My throttle body pretty much took a crap. All I asked was if anyone knew a way to essentially "turn off" dbw. We are gonna try. Mk4 its as easy as vagcom. If it doesn't work I'll just buy the 80mm Hemi body I.E sells.

      Ya I'm the only one that touches my car, unless custom tools are needed

      Also brake boosting, left foot braking, and total front and rear brake bias tuneability. Has anyone been able to enable left foot braking while blipping the throttle on the DBW in a tune? I thought not, which is another reason I'm looking to do this.

      I right foot break and blip the throttle on down shifts all the time. Could have sworn that was how you were suppose to drive. I doubt any of us have cars that merit left foot breaking unless someone has some sort of really huge overkill track break setup that needs heat kept in them. The front to rear bias tuning would be really nice.

      Idk, when I brake in a corner and push the throttle with even the slightest brake pressure it cuts all power and takes a second for throttle to work again. But that was on Unitronic, I have not tried on the UM.

      Can't do anything with the pedal box till my hand heals anyway because you have to heavily modify the fire wall.

      I'm starting to look at it this way 3600$ total for fully adjustable brake, clutch, and gas pedal is it worth it? Car is retired as a daily driver.

      For me there would be a lot on my list to spend 3600 bucks on before those mods. However i completely understand your justification for it and it would be really cool to pull off.

      A local shop has offered to do the fab work as payback for all the times I helped them. There is a dbw pedal box but its terribly expensive. You can also get just clutch and brake pedal box which is what I'm leaning toward.

      And no dbw can't simply be turned off on the mkv. Somebody has had to of done it!

      3600 includes box, fluid, stainless lines, front bbk. That was a crude estimate.

      I want to do.it, it.would be very cool but I think I'll just get a new throttle body and keep an eye out in Corvette forums for a pedal box to show up used.

      Seriously...why? No seriously..... WHY? the left foot braking can be tuned in.mine does. And brake boosting can be done as well....shoot even apr had left foot braking enabled
      ... No body needs a new box unless they have a fully built standalone managed full on rally car built for some serious pro driver

      god i love my car. it may not be fast, but it's crazy fun!

      No it can't. I was told it could, I'll tell you who said it, they are kinda known, but when I dropped the car off really quick it was clear it can't just be turned off. They said have it written out which again I doubt can be the case, and then I've been reading standalone is the only way. Also been reading the Corvette and GT40 forums on this idea and those guys just swap the stuff out and call it a day.

      one of the forums has a dbw box fs for 400$, but I need to sell my wheels or parts before I can even think of buying it.

      Just think it would be cool to have. Wasn't really a thread about doing a pedal box, more can dbc be done because my second dbw throttle body is acting up, just a local guy has one going in his mk4 track.car.

      Good because whoever told you it could has 0 understanding of Motronic systems.
      The throttle body is not a simply an on / off switch. The electronics behind a DBW throttle body are much more involved than what people think. If you get in an accident , your throttle body shuts off , if you press brakes your throttle body closes and these are just simple tasks...

      DBW to DBC conversion can only be done via the following:
      • Standalone system
      • Bosch Motorsport plug & play ecu - $12,000+ USD

      If you have a mafless car im 99% sure you would need a custom tune as the throttle plate size difference screws up the airflow where as the maf reading normally compensates it

      my car isn't mafless, and I haven't hooked it up to see if it works. It should work according to I.E. If not I'll sell it no big deal, tons of 1.8t guys could use that and the adapter plate.

      This is in my way atm, no.working on the car for months.

      The car is on standalone which I did not know. I talked to the guys who did it, before that, the owner is the one who said the shop did it through vagcom. They did not use vagcom like the owner said.

      Qft Keep me posted on that swap. I have my eye on a b7 s4 that has a blown motor and front end damage. A 2.5l would be awesome in it.

      You broke at least your 5th metacarpal and looks like probably 3rd and maybe 4th?...did you punch something? Whoever did you your surgery left those K wires really long! Good luck with the healing/physical therapy!

      No bmx accident. I broke those 3 top bones, they dislocated, broke 4 bones in my wrist, and fractured my forearm. They had to be that long. They're just gonna yank em out with pliers when they're ready
