VCM Suite tune for SV6

[GTRwilson]

Ive been through the FAQ's but they seem to be a few years old so i thought id start this incase theres been anymore updates with it and get some accurate pricing.

So what am i looking at for the tune? have heard about $900?

Also, I have been told power of up to 201KW give or take after tune. Would this figure be including a range of mods like 2 hole, exhaust, filter ect or just stock?

Basically, I'd rather leave the exhaust if possible, would this effect the chances of a decent gain through the tune?

thanks people!

P.S waiting for andyman to reply to this thread too.

I have had it done to my Calais and it gave me 201.1 RWHP so approx 201 FWKW.
Mine was completely stock, not even an air filter change at the time so with those mods possibly looking at more.
A good option also for quicker acceleration is diff gears, there the way to go if you want a quicker take off, a tune help all over the rev range.

[GTRwilson]

Hmmm. Ive been thinking of diff gears atm too, to go in before a tune. Whats the cost of these though? What do the SV6s come with? have heard of i think 3.45s being used?

Also, what was the cost of yours if you dont mind me asking? PM me if you like. Where did you get it done?

[cold_carve]

Seeing as your in Brissie GTRwilson, dare say pop ya head in at Matt Stockers, hes had thorough involvement with alloytecs and the sv6's expecially as ya know by one privalaged member!

[Ewok]

Had a recent quote by VCM, still $900 for the tune.
The increase in power they quoted was based on a stock car with the tune. They reckon 20-30rwhp gain. I had my sv6 dyno'd last year stock at 65,000km and pulled 193rwhp with nothing more than a K&N air filter.

A lot of people are going for 3.46 diff gears (standard is 2.89) as they provide good off the line acceleration. Think impulsive ran a 14.4 sec quater with diff gears, zorst, cai and tune.

haha also, clicked the link that kept flashing around top of the screen RE: performance manifolds intake manifolds. they gaurantee 25rwhp gain in power over whatever you already have bolted on or done to the car. For a stupidly priced $1900 + shipping + gst. Uh yeah, they are living on another planet and they can get f**ked.

I had my Tune done at castle hill exhaust in sydney, it was $900 or $950.
The auto's have 2.89 diff gears and as mentioned 3.46 are usually a good balance.

[GTRwilson]

So is VCM a shop themselves or do i go to any tuning shop that would know how to do a VCM tune?

who/what shop is matt stockers? got details?

As for diff gears. Ive never had any experience with this sort of mod. Would it be something attempted by myself? What the cost of just a set of diff gears? Where would i get them?

Doesnt changing the diff gears also put out the speedo? Would this be corrected if i got the VCM tune, or would i need to get it done elsewhere?

hope that makes sense, thanks for the help people.

[monaro327]

yes vcm is a shop but they are in vic you need to find a tuner in qld that has vcm suite and some experience tuning alloytecs. alloytecs are alot harder to tune the the LS series so don't just go to anyone.

yes changing the diff ratio will thorw out your speedo but yes vcm can fix that when tuning.

no charging diff gears is not easy in fact it's a science but the easy way is to get a complete diff housing with a different ratio and change that yourself. SS etc have different diff ratios what they are in the vz i don't know do some searching.

[Ewok]

Yeah, what Monaro said. It does throw out the speedo just a little, but take it to a holden shop after the gears are installed and they will be able to calibrate it for you easily enough. Also, as a point of interest, having diff gears put in, only really increases RPM's at highway speeds (100kmph) by about 200rpm average (been doing a bit of research into this hehe).

[jimmybobrowe]

So what would the fuel economy be like on the highway? I've been getting around 7L/100km when driving home to South Aust, and its one thing I'd like to stay roughly the same! lol Most of the performance is at the complete opposite side of the scale of fuel economy!

[cold_carve]

VCM Suite too is able to recallerbrate the pcm to take into consideration of new diff ratios.
As for Matt Stocker's contact details, pm RaptopSC, as theyve been working with each other on the supercharging of the alloytec engines.
Btw that hp figure too sounds on the money for an SV6.
Yeah as for the autos theyre running 3.08s the manuals that run 2.89's

[Ewok]

Ah, thought there was a difference between the auto/manual diff ratios, thanks for that. Yeah, as for the rwhp dyno figure, few people arked up and called bullshit/happy dyno/quater mile it/ etc because they were pissed they spent $x on their car and pulled the same figure. I've got it on good knowledge that the dyno I was on was a reputable and reliable one.

[monaro327]

i copped a bit too ewok my car made 200rwhp on the CHE dyno. so many sv6 make less then that with full exhausts and tunes. Dale says my cars a freak, just wish vcm would get the bloody ve update out so i can see what this freak will do.

as for fuel econ, 7 is about right in a vz on the highway i'd say. my fat ve does 7.2/3 on the open road. about 9.1-3 round town. most bolton perforance mods increase fuel econ extractors cai and tune will improve fuel econ dramatically if you drive it nicely.

the alloytecs run rich from factory mine was running 11.5:1 on the dyno they lean them out to 12.5: with a tune so you can see instantly you will get better consumption.

[GTRwilson]

Do all shops do a before and after dyno run for the $900-$950 VCM suite tune?

will be interesting to see what mine makes. Would said shops do my diff gears at the same time or is that suited for a run of the mill mechanic ect? What would this cost?

[GTRwilson]

thought id ask this question in here, rather than me make ANOTHER topic

Has anyone had any problems with mods such as: Phreedy dash mods, VCM tune, 2 hole mod ect voiding their insurance when making a claim?

[monaro327]

i'd like to see the go to the effort to prove your car is tuned. there is no easy way to prove a alloytec has been tuned as you have to retain all factory sensors. with the v8's it's easy no maf non factory with the 6 they'd have to pull out the ecu and compare it's tune to a stock one which they'd never do.

but you'd be best to ask your insurance company we can't speak for them.


yes they'll do a before and after they'll probably to several runs as they are tuning.

what about a before and after run at the strip?

[GTRwilson]

The increase in power they quoted was based on a stock car with the tune. They reckon 20-30rwhp gain. I had my sv6 dyno'd last year stock at 65,000km and pulled 193rwhp with nothing more than a K&N air filter.

So based on this, a power of around 210-220 rwhp can be expected? can someone put this in KW for me haha. Is there a calculator or something for this?

every car is different, every dyno is different, hard to expect an after power figure when you dont know what your before power figure is,
with K&N filter, full exhaust i was 193rwhp before tune....


get in touch with Hi Torque Performance, they will look after you, they tuned my sv6 they also did my diff gears

Hi Torque Performance
KW to HP Convertor

[Ewok]

Yeah, what impulsive said pretty much. You can add all the mods in the world to a car, but if you don't have it tuned for those mods at some stage, the power advantage remains dormant/goes to waste. The only other way to really verify the gains, is, to HIT THE QUATER WOOOOOOOOOOO! 220rwhp = 164rwkw based on International Horsepower base figures. Bow down to the all mighty Online Conversion - Power Conversion

Gotta get down to a whup ass wednesday at Motorplex sometime to do a few quaters ............ I reckon 15.1's stock with my current readout .......... We'll see heh

15.1-15.4 @ 89-92mph i reckon, completely stock

[GTRwilson]

thats a nice figure. I know of some fag in a POS old school intergra, claims to beat new model SV6/XR6s by car lengths, yet only got a 15.3 i believe.

would a mid 14 be possible with just a VCM tune, diff gears and 2 hole mod? i know that all are different ect but ball park figure is that about right? Auto too.

i ran a 14.37 with diff gears, 2 hole mod, Hi Torque Performance tune. mine is auto.
havent heard/seen anyone get close yet, done in qld weather too...


...well, have heard of a ute going quicker, but only heard... havent seen any proof or vid yet...

[Ewok]

I want to get some proof of that CAM'd SV6 runnint 13.5's. Shame that it's $3500 for CAM job as you have to replace 4 of the bloody things >.< heh

[Nitronic_12]

I wish they didn't have that 125KW/1000Kg Ratio. I have to wait 4 years before I do anything serious to my car. But if I can get an extra 10KW at the flywheel, that'll still be legal, not that anyone cares, but the rents can do maths. Anything over and I'm in trouble.

So if I wanted to do a tuneup for my stock as a rock Calais, down here in Vic should I go to VCM?
