Just an awesome piece of work mate, now the fun begins
I’m really surprised/impressed by how well it drives straight off the Hoist! Wasn’t sure what to expect from my suspension/steering design..
thats always a win! What was your final suspension/steering design?
September 24, 2015 at 9:37 pm #9616yes that’s a possibility with the BCM bus master. I haven’t read the specs on the custom code for a while but I believe all the trip computer stuff works.
September 24, 2015 at 9:36 pm #9615yea my pwm controller is a great piece of kit, I just need to get around to getting it hooked up properly
Which controller are you using?
September 24, 2015 at 6:50 pm #9599The problem is the way the dash is driven, to use a late model dash you would basically need to upgrade the PCM and associated bits and pieces because from VT onward the dash is driven by the PCM via the can-bus. Also depending on the model the data/communications protocols change as well so it gets fairly technical. The guy to speak to would be Tazzi as he’s right into dash upgrades. He can be contacted on the PCMHacking forum or Just Commodores. He’ll be able to give specifics of what is required for the various model dash’s.
In theory, for a V6 you can use an ecotec VY dash and the ecotec VY PCM everything should work as per the factory with the exception of VATs which youd need to turn off. Or ‘424 PCM with modified code for Class 1 dash data
For 5L you could use a LS1 pcm + PIM from a VY or the stock ‘424 PCM with modified code for the Class1 dash data
Note.
‘424 is a VR v6 PCM, VR/VS 5L PCM.
VY ecotec flash PCM is the same as a VX
VY Supercharged Memcal PCM is the same as VT Ecotec and VX-VY Supercharged PCM
Shouldn’t be too hard to get the electrical side going. Might give it a go on day one I finish all the other mods…

September 24, 2015 at 3:48 pm #9567VY dash would be a nice touch, matches well with a VY indicator and wiper stalk haha
September 24, 2015 at 3:44 pm #9566..that would be a awesome way to do it as its load detected so the pump doesn’t go flat out while goin back gears as a rpm switch would
Yep exactly, so its basically matching the pump performance to the actual fuel demand, which is basically ideal. As you say if you are doing 5,000 rpm on a downshift blip it needs next to no fuel, whereas passing through 5,000 under wot it needs full flow. Such an interesting subject, I mean basically we are able to put JDM “trickery” into our cars now.
The Delco PCMs in the supercharger v6 commodores run a fuel pump controller. The PCM changes the fuel pump speed based on fuel demand so its not always running full tilt. I think the VU LS1 ute also had one
September 24, 2015 at 3:42 pm #9565I’m not sure I know with the older holden delco ECU it can be done by the power economy button and kalmaker do provide for lots of stuff such as water meth activation, pretty sure you can tune in 2 different tunes using the power economy some how so one with normal timing and one with certain timing pulled out I would imagine there would have to be a way of doin it as lots of LS powered cars have NOS i have EFI live so I would just go in and select every thing above a certain rpm like 3500 as I know when I change gears I’m still above that or if you have a auto just take it from just above the converters rpm and just take out the desired timing for HP of nos, as above its 4 degrees for 100hp and 6 for 150hp (not sure above this HP though) but it all comes on the sheet when you buy a kit best of talking to a tuner about that as different tuning programs can be set up different so it’s not just 1 way of doin it and that will work with efi live, HP tuners and ls1 edit each program may or may not require a different wiring pin to ECU for some sort of activation switch to know to pull timing out
EFILive have a custom operating system for the LS1 PCM that has a NOS function, you wire up to a spare pin on the PCM and when it is activated the PCM switches to NOS fuelling and spark table.
September 10, 2015 at 10:08 am #9092I got a set of vented IRS rears I’ll never use again , slight lip,light machine all good. You can have them if you pay post & show me fast lines round lakey one day
What sort of calipers go with those discs?
September 7, 2015 at 4:22 pm #9012thanks for that. Interesting info on those cones.
September 7, 2015 at 10:09 am #8998Cheers mate, great to have you part of the forum. I have certainly learnt a hell of a lot during this build. Apparently its not uncommon to take a basically new car and it fails a full emissions test, its a very strict. To get an ITB fed 454 NA through I am really happy about, it took a lot of effort, it almost became an obsession for me to totally pass engineering, tbh I think a lot of people would have chucked in the towel (or run out of money lol ). But its something now nobody can take away. I can drive into any car event knowing its legal, whereas I would have always been worried it would get pinged. Those exhaust cones work very well, as you say it wasn’t enough in the final wash up for what I needed, but if anyone was just needing to drop a few dB they are a great option. With my car I definitely think there is a harmonic (or two) in the exhaust note that gives it such a high reading. At some stage now its been tuned properly I will recheck it, I am pretty confident it would be under. I just got to the stage where swapping the exhaust just got it done. Probably if I had more time (and inclination) I reckon a hemholtz pipe would have been a good option, particularly now I have widened the area where the rear muffler sits.
Are those the perforated cones? Do you have any more details on them?
August 28, 2015 at 3:03 pm #8811cheers guys, appreciate the photos. will get getting stuck in fitting them next weekend and post pics up.
Track days are great fun, just finding the time and who runs them at a reasonable price is the challenge haha. Oh and the list of mods that go to the top of the list immediately following a track day…
August 27, 2015 at 10:14 pm #8779thank’s for the reply guys, I ordered 2 red bolt on straps earlier in the week and I’ll cut a slot in the bumper and have it hanging out. Easy to fibreglass the holes back up if I ever need to.
Who was running the super sprint?
August 24, 2015 at 8:32 pm #8738That is good news, especially for aussie engineers!
August 24, 2015 at 1:11 pm #8726A guy on the VG-VS holden utes facebook page has run this setup before and i will be going down this path soon. Will be running vt-vz lcas, knuckles and hubs with adjustable radius rods. Will put up pictures once i get around to doing it.
what’s the reason guys go VT LCA’s on a VS? I know on the vn-vp they do it to gain track but the vt and vs arms appear to be the same length?
August 23, 2015 at 6:27 pm #8688Is it possible to get notifications for a thread without posting?
Georgie is right in the middle of uni exams right now, so she may not reply to this for a few days but we aren’t ignoring you
No worries, just new here and checking out the forum. Appears to be different software to most other forums.
Good luck with the exams Georgie!
August 23, 2015 at 4:39 pm #8672Hey guys, Thanks for letting me know about this. There is a checkbox under the emoticons that says ‘Notify me of follow-up replies via email’ – is this not working for you? I can look into implementing a feature in the next upgrade which allows you to follow posts without having to reply! Georgie
Is it possible to get notifications for a thread without posting?
August 23, 2015 at 4:38 pm #8671awesome thread, I was following on SC but might stick with this forum :XD:
August 23, 2015 at 3:52 pm #8663If you use the VT arms you might be able to get more caster, with VS arms and adjustable radius rods, you’re limited by how much caster you can put in as the wheel rubs on the guards. With the VT arms it looks like the wheel starts off further back in the wheel arch so you could get more caster – possibly…
Can you tell if the VT wheel hub bolts straight up to the rest of the VS suspension? Struts are the same but is the flange and ball joint location compatible?
P.S. Apparently the VT S1 ball joint connection to the hub is pinch bolt, VT SII onwards is tapered.

August 23, 2015 at 3:39 pm #8661VS stock manual pedal box here and works fine, you do need to kick your heel out a little more than most jap cars but not a big difference. Drove without the rubber pad for ages but it does help a lot with grip :XD:
August 23, 2015 at 12:13 pm #8650where did you get that bit of trim around the hole where the intake pipe goes through the body?
