    Vl turbo won't rev past 4000-4500rpm

    Yeah mate, got car back from tuners today. Made a massive 270hp . problem was the rev limiter in ecu wasn't saving on anything other then 4500rpm on one of the settings. Changed setting and was able to adjust the rev limit up to 6200rpm

    Vl turbo won't rev past 4000-4500rpm

    Can the crank angle sensor or chopper wheel be installed upside down? Looks like it would only go one way to me , but I've only had a quick look at it

    Vl turbo won't rev past 4000-4500rpm

    I'm just going to try try a new crank angle sensor tomorrow , there only roughly $100 and that way I know its new etc , if that fails I'm going to a mechanics but not to keen on taking it there to be charged $100 an hour for them to probably not even sort it out. We have one dyno tuning joint in...

    Vl turbo won't rev past 4000-4500rpm

    It makes 20psi on 20psi by 4200rpm and then cuts out at 4500rpm so makes boost and then quits. Its just confusing really , like its the crank angle sensor but runs fine drives fine etc until 4500rpm sometimes 4400rpm or 4700rpm but never get it over 5000rpm and never happens before 4000rpm

    Vl turbo won't rev past 4000-4500rpm

    I've tried it on 10psi even 8psi still does it at exactly 4500rpm every time. Plugs are gapped to 0.8 which shouldn't be blowing out with 10psi

    Vl turbo won't rev past 4000-4500rpm

    Yeah pulls great on 20psi until it just stops pulling , but yes it sort of does feel like a rev limiter but its set at 6000rpm , its not getting close to that at all...I'll try turning it up to 7000rpm and see what happens...

    Vl turbo won't rev past 4000-4500rpm

    It revs good when not under load , underload revs fine until 4500rpm and just hits a brick wall sort of thing, throws you forward ...it does have a rev limiter on the microtech but its set at 6000rpm I've checked that a few times...I was thinking that CAS but pulled dizzy cap etc off the other...
