Even if you turn off VDC your going to have a hard time doing a burnout in an auto V35

Reason being is as a safety feature

When you press the accelerator and the break pedal at the same time, the the engine has its power cut to about 20%. Why you ask? well remember not so long ago all those people in Toyotas in the US who had their cars accelerator jam and then ended up driving along at 100mph+ to their deaths as they were too stupid to turn the key to the off position or move the gear stick into neutral. Most cars these days have engines powerful enough to overpower the brakes and as the brakes get hotter unless your running high temp pads the less they work. The whole idea is that if your pedal gets jammed as soon as you press the break pedal the engine has its power reduced to a level that the brakes are able to deal with and slow the car down

Now you wonder how dose one bypass this in order to do a burnout?

Pull off the fuse box kick panel in the car and remove the brake light fuse, now this may take some trial and error if you cant read Japanese

Once the fuse is removed the car wont know that you are pressing the break pedal and allow 100% of the cars power to be used

As you may notice by my avatar I may have had some experience doing this myself :P

My 2001 model 300GT did not have this feature :P

I don't have a definitive answer, but many have stated that if you just press the VDC off button, that it does still work if you exceed 60km/h or really get out of shape. I have also heard if you hold it down for 10sec, it turns off completly..

Haven't actually tested any of this myself though. - and no idea if it impacts wanabe said..

I thought the 2001 300gt didn't come with VDC?

The 2001 300GT did not come with VDC note the quote of one of my other replys, they didnt come with it until 03 i believe.

      Boost level and torque curve

      As someone who has been playing with turbo things for some time now, be prepared for this to not be the first time feeling this way    I'm busy as atm, but if no one else covers the things I'm realising are worth mentioning to you then I will when I have a chance as it seems like I overestimated your knowledge on how turbos and wastegates work.  Otherwise I recommend having a look around how wastegates and boost control work, really anything on understanding the general mechanism of boost control as it will help you find the answers to the questions you're looking for.  Your initial question jumps some fundamentals.

      I don't understand anything anymore.

      so this is an anomaly??? I thought it was a voluntary increase

      we can only guess exactly what happened from our keyboards, but to me it looks like they were targeting 27 but the wastegate was too small or poorly controlled and the boost crept up, that is quite common

      Good points!  Took those for granted - though I *did* actually give an example of winding boost up more than it had been before where I wasn't actually specifically looking for more peak power.  The Toyota Starlet dyno plot that I shared and mentioned showed an overlay from the previous tune it had and the one I'd redone, I left the boost targetting the same as the old tune but then after peak power I ramped boost up by a good 5psi or so over what the old tune had at the same rpm. The reason I felt comfortable with this (though the owner of the car had a "are you sure?" moment when I suggested it) is that the setup wasn't turbo limited, it was largely head sealing limited and the owner was a bit concerned as for the last few seasons he'd had issues with head lifting - sometimes not completing an event without having some headgasket issue, so he didn't want to run any more boost than it was. The reasons I was ok with raising the boost a good 5+psi MORE than that was that I left it where it was in the middle, and only increased it where VE (and therefore cylinder pressure vs psi) were dropping hard and I didn't stop the torque from dropping, just reduced the drop.  Well, there is that and the fact that the previous tuner had it overtimed by near 7degrees at peak torque - but that's another story haha.    I didn't really go into detail about that "turning it up more" thing but now you've mentioned the "not detuning", sometimes the boost *can* be turned up higher than you'd expect if the setup allows for it and you do it smartly.  I've tuned things to run 30psi on BP98 "safely" that a few years ago (or still?) people would cry that it was a stupid idea - but given they were well intercooled, low EMAP turbos and only doing that kind of boost where VE is dropping etc I was pretty confident it wasn't as cowboy as it sounded at face value and we never ended up with issues as a result of it.
