    so I’ve got a vt commodore I’ve turbocharged and got tuned and when I try to do a stand still burnout it won’t rev past 2000rpm, it’s an auto and also it will get the wheels spinning if I do a doughnut but will stop when I have the brake and accerator down. It hasn’t got a traction control button and no abs module. The guys who dynoed it say that there could be something that’s connected to either the brake light sensor/button or the cruise control one, anyone here have any knowledge on this stuff?
    Vt commodore 2000 Sydney Olympic is the car name

    Lol, get ready for a flaming.

    Take the brake globes out and see if that changes it then.

    Possibly anti-abuse too. Car is revving out but the ECU isn't seeing any speed change from the VSS, so it won't let it over rev.

    Also likely to bog down in doughnuts if you're still running a single pegger/open diff.

    You keeping it in first?

    What ya mean by a flaming?xD
    And it’s got a mini spool in it and I just read up the anti abuse thing and it seems that may be the case. Also I’ve had it in first then I tried just in drive it doesn’t make a difference.

    I’ve pushed it Down hard and soft tried it all at this point that’s why I’ve come to here

    I’ve also tried to have the brake lights not connected and do it but nothing so I’ll try the cruise control one tonight and see what happens

    A guy at work said line lock the back brakes but correct me if I’m wrong it doesn’t matter if the back brakes are working or not cause it’s a computer thing right?

    I’ve checked the page out when I first found out, and I’ll remove the cruise control plugs tomorrow and try because I’ve already tried with the brake lights

    Could your tuner not turn off the abuse safety in the tune?

    commodore has anti abuse in the software aka take out the fun
    basically if assumes you are trying to do a hill start and limits the power to prevent wheel spin
    it is the input to the computer not the output
    unless your car is built to take this abuse stop it
    as for flaming
    stop being a tool
    a v6 commodore is not a street outlaw

    The guy who tuned it the first time didn’t even know it was a thing till I’ve brought it up. He said he will do some research n get back to me

    I realise we should not encourage destructive behaviour on public property. But this is a bit harsh I reckon. Some of the coolest and quickest car builds on this site have been boosted V6 commo's (mostly 2nd gen, but still). Ok, not an avid 'street outlaw' contender, but only 0.000001% of cars world wide are.
    OP is building something cool (hopefully he will post pics to confirm) and I'm keen to help where we can.
    But OP, please try to find private property or personal skid pads for your 'testing'.

    Sounds like it doesn’t have enough power to spin the wheels tbh. Don’t think the vt’s smart enough to limit torque with the v6’s. The v8’s have torque reduction for sure though.

    First post says the thing is turbocharged, as long as it's not stupidly big and laggy it should have enough power to break traction at a minimum.

    You know when you hit full boost OP?

    Yeah definitely I have a mate who has a place but it isn’t close so it’s more of a go down for the weekend that’s the only reason I’m “testing” on public roads, also it’s a t3t4 turbo which is .53 air compressor and smaller exhaust side, also at the moment I’ve been having problems with my boost gauge I have a feeling it’s broken but I’m going to get someone to check it for me, it seems to come on boost around 3000 maybe a little less

    Turbo is kinda big from what I’ve been told but is ment for a v6
