    3.8L v6 Ecotec in vx commodore wont rev out

    If it's back firing I would suggest looking into the dfi module, CAS, and cam position sensor, as these are the only things which control ignition timing, I resmember a really really good thread on testing ignition modules (not just the module as uv replaced yours twice but the operation of...

    worse day for my vt yesterday solved and worked out alot of problems

    How does throttle cable slack affect vacuum at the same rpm? Aren't u technically reaching the same throttle position?

    Has anyone installed one of these speedo correctors?

    I spliced into the speed sensor wires just before it enters the ecu, I didn't have trouble with the gain though (newest module which replaced the kit) I have T56 which when doing 100 said I was doing 40 lol so can't complain with that part I guess....

    Supercharged VX starting difficulties recently. Now wont start at all.

    Use a screw driver as a stethoscope and check to see if injectors are working, take out plugs and see if you have spark (use a spark tester) failing that check spark at leads, failing that check at coil tower, even if you can hear injectors working take off fuel filter hose off (hose on engine...

    Assist spring - VU ute

    Seeing as the vs is a chain I ended up cutting it and using a hose clamp lol works good though now!

    Assist spring - VU ute

    If it's similar to the vs set up, you need to shorten the chain the amount youv lowered it eg 30mm, it's a needle type valve on the vs , you'll find you'll have a lot of brake dust on the rears and brake excellently reversing down hills lol but what made me aware was when it was wet and I had to...

    What is easy worthwhile proformance mods for vs v6

    Depends on budget and skill (how much you can do yourself) Crown wheel n pinion ratio, Cam and supporting mods, Intake manifold spacer, Vt up injectors , rail and fpr Exhaust, (extractors inc), Replace crinkly intake tube And tune But really for that money u could boost it which...

    Adjusting hand brake - no hole to adjust

    Why not just tighten the tensioner where the 2 lines merge to 1? Or have you already maxed that out?

    Not surprised you came unstuck with a spool around a round about in the wet, spools aren't legal on the road and you can see why..... Hope you never hit anybody cause you'll have no insurence

    Intermittent Miss firing only when starting

    I got code 47 the other day but that's no indication of cas as it runs through the dfi to pcm, fuels fine new pump, regulator, injectors reco'd , and it's misfiring or just endlessly cranking then for no reason what so ever you go to start it and it starts fine that tells me spark ..... Or...

    Want to build a motor

    If you want to spend the money ull have a pretty sweet v6 and will be quick sure it won't be a super car or anything but hey probably quick enough for any normal person, clearly it's just a project and if it's what you enjoy, you should.... Iv done the same thing iv got an l67 with t56 sure...

    Faulty DFI module?

    You can test the cas with a test light or multimeter , you just put pos on pin in dfi connection and earth on chasis and watch as somebody (not female going to bug u and get annoyed at you ) cranks the engine, you can test both the 3x and 18x signal Iv read a lot recently that the earth can...

    Intermittent Miss firing only when starting

    New CAS in and it seems to start immediately now even when cold (used to crank for 1-2seconds) well most of time, anyways long story short it still intermitantly won't start will just crank endlessly and sometimes (during the no start) will miss fire ..... So I'm a bit lost cause cas is...

    Want to build a motor

    You could spend 3 k and get a nice reliable motor, no need for 8, forged Pistons , h beam rods, double row timing chain , cam, associated valve train components and a decent head gasket are all they need and the usual new bearings n gaskets throughout obviously and you can just build it from the...

    [Ecotec] Upgrades for burnout cars

    Locked diff, shorter ratio crown wheel n pinion, I would assume being charged an intercooler and manifold insulator would work well, cam obviously would be ideal, rockers if not, a mail order tune and a good service I think will go along way! Maybe you need to look into some bigger injectors...

    How do I take my vt engine out

    DONT USE THE PLENUM so many idiots do and break them it's only cast alloy and cant support 350kg! Lol

    Want to build a motor

    Having done this yes I agree with EYY , just buy a $400 motor and if u want longevity through some bearings and gaskets at it , job done it blows up get a new one .... An Eco could probably handle 15 pound daily for a while iv heard of people running 20 on unopened engines just fine

    Intermittent Miss firing only when starting

    Interesting, I hope this is the problem either way I got a new CAS coming so if not I can cross it off!!

    Intermittent Miss firing only when starting

    So it's happening more frequently now, but it's strange because this time (20 min ago) it didn't start so I got some cold water splashed on cas and it started fine, but it's never ever cut out on me while driving just refused to start.... I thought if they went they cut out on you?

    Intermittent Miss firing only when starting

    So just traced my ebay history and found that the CAS wasn't genuine it was an aftermarket part, I'm thinking this could be the problem.... Even though it's been in for over a year approaching 2 even I think it's not genuine and I don't trust it for $38 it's worth wacking in a genuine!

    Attempt to fix crank angle sensor my self?

    Are you certain it's the CAS? Something's wrong if you've gone through 3? Don't the mechanics offer some sort of warranty? You sure it isn't a swirl pot issue (no fuel in swirl pot when you turn a corner sharply) Cas replacement is easy just remember you need a new harmonic balancer bolt...

    my vs v6 ecotech seem really guttless

    Fuel pressure regulator (the diaphragm gets ruptured, easy tell if you take off vac hose and smell it if it smells like fuel chances are its buggered), Iacv is intake air control valve or stepper motor which is basically the bypass at the throttle body which controls your idle etc they get...

    V6 replaced into car that was a Supercharged V6, now chugging at idle, what's wrong?

    Hmmm wonder if your loosing vacuum perhaps one of the vacuum connections you didn't put on goes to the vacuum ball and is subsequently making you loose vacuum from all the other vacuum points..... Supercharged tune also has 2 deg more base timing advance but should be fine .... What...

    vr ss 185 clutch swap problems

    You probably have an aftermarket flywheel? Might have to buy a clutch kit with a flywheel included, then just flog your old set probe be cheaper than anything else, don't think you'll be able to use your pressure plate if it's had a button clutch through it they tend to dig trenches but check...

    Vr v6 wont start.

    When it's failing to start is the VATS light flashing? It should turn off when your key is on ignition or start....... Is it just endless cranking or not cranking at all? Could be cas or dfi if it's getting no spark or fuel Scan for codes
