Oztrack Tuning is an Australian Reseller of the EFIlive Digital Tools for onboard vehicle electronics. This brand offers market leading scanning and tuning software. We also provide support & training for clients who purchase these tools from us. This extends to DVD Video Tutorials including audio commentary and on screen footage of the tools in action.
Oztrack Tuning also aims to provide a leading pcm tuning service for people who have cars with Gen III or IV engines. This involves doing both MAF and MAFless tunes on the cars.
The aim is to provide a service within the budget of regular car owners not just enthusiasts that race their vehicles. All of our activities are willingly explained to the customer, and some are even given an introduction to the use and operate all aspects of the EFILive Tuning system.
Oztrack's Clubsport was the NSW Season Champion in 2005/2006 in "Super Street" Drag Racing it ran a best of 10.9/123mph. So we certainly know what to do to get maximum performance from these vehicles. This car could accelerate 0 - 160kph in 7.0s and could still get under 10L/100km cruising at 110kph on the motorway.
Our new race car is almost ready to start racing in Super Sedan. Its a white version of the old car but has a far more powerful 6.7L engine, bigger tyres, bigger stall converter and more. We expect it to be racing soon in the low10s in naturally aspirated form and no nitrous.
We have had great success tuning the new VE 270kw engine and the 307/317kw HSV's. A couple of years ago we started tuning a blue VE SSV with an A6 gearbox which still holds the honour of the fastest time in the world in a NA VE Commodore while retaining the stock 6L80e auto box and converter. Since then we have tuned around 100 VE Commodores.
In factory supplied unmodified VE 6L or 6.2L that we have done the usuall result is very positive. They improve in throttle response and have increased torque right through the rpm range. The extra torque below 2000rpm usually gives the car a boost in fuel economy as well. Cars with 6spd autos can gain even further with improved shifting and better behaviour from the gearbox overall. The Basic 6L & 6.2L tune costs $500 or if the auto box is done its $650. The gain in power is often a question asked, its usually around 20rwkw or close to 30 engine kw. We often see VE 6L and VZ L76 6L engines make around 260rwkw (325 engine kw), recently we saw a VE L98 make 286rwkw with from a mafless tune with minimal mods - it was just equipped with extractors and over radiator intake. It still retained its original cam and catback exhaust.
We also have some nice exhaust systems, over radiator intakes, clutches on offer that are installed by WCC Performance at very competitive prices. Below are some experiences we have had with modified VE's.
in 2007 a Blue VE owned at the time by Paul Jarman had a 224 228 114 cam and some imported CNC Ported L92 heads, full exhaust system and an over radiator intake . It made 326 rear wheel kw (400 engine kw) and backed it up by being the 1st Naturally Aspirated A6 Commodore to run into the 11s bracket in the world. Its best is run was 11.867/118.7mph at WSID and this was done with the car still retaining all seats & full exhaust. We just changed the wheels and took the out the air filter,spare and jack. The car did during its 11.8 run 0-100kph in less than 4.0s and 160kph in less than 9s.
We have seen numerous VE Commodores and HSVs recently make over 300rwkw. We have even seen as much as 320rwkw from our most common cam the 220 220 112 & 336 rwkw from my new favorite the Stealth II while it idles at 650rpm. These cams can be tuned to idle at 650-700rpm or roughened up for people wanting that. It can get great economy because it pulls smoothly and strongly from 1000rpm to 7000rpm.
All of the work done can be arrange by Oztrack Tuning in co-operation with WCC Performance. We have a wide range of modification packages that we can believe in and strongly recommend. We can supply and install highly recommended choices in exhaust systems, intakes, manifolds, cams , heads, blowers, turbo systems etc.
Recently we have done a few VE Commodores with Forced Induction and we have some great combinations we install. Its quite easy to gain near 400 rear wheel kw in an A6 and still retain nice driveability and road manners. A VE 6L twin turbo that we did has been able to make 440rwkw and can still travel on trips in the mid8L/100km range.
A good recommendation is to install a small torque cam We offer one cam we have called the Oztrack Gen IV Torque Cam. This package gives incredible torque from 800rpm and it is far superior to anything else naturally aspirated that we have tested between 800rpm and 3000rpm. Its close to Supercharged Cars even when at around 2000rpm! The good news is that this cam can give touring fuel economy around 1.0L/100km better than stock and has far superior street power. The kind of power you would notice everytime you press the accelerator even a small amount. It idles so close to stock in most cars you cant tell the cam has been swapped.
We also have developed another cam called the Oztrack Stealth Cam II, this cam is able to mix it at high revs with cams that are far worst behaved at idle eg 224 228 112 , yet the cam idles with a small amount of lope only.If the car has a quiet exhaust it is almost not detectable. This cam is able to pull down low not far at all away from the Oztrack Gen IV Torque Cam yet it will be far stronger above 5000rpm.
Gen IV Torque Cam packages for VE 6L and 6.2L are about $2700 inc single springs, the Gen IV Torque Cam, Moly pushrods, Fully Tuned on the dyno and Installed.
Stealth Cam (and all other cam profile) packages are about $2900 including the custom grind Comp Cam, Double Valve springs and Moly Pushrods, Fully Tuned on the Dyno and Installed.
Dyno Tuning VT-VE Gen III & IV
Written by Steve
Saturday, 01 July 2006
The Full Dyno Tune involves careful measurement of many more parameters and more time spent customizing the settings.
A statistical procedure is performed from logs gathered using EFI Live that results in much more accurate air fuel ratios in all conditions.
Most owners will notice an instant gain in power everywhere. It should give more power than a stock GTS 300kw tune and with the stock cam with any A4 around 210-230 rwkw and M6 around 220-240rwkw. Some owners notice an increase in smoothness of power delivery. Overall Fuel economy usually improves as cruise air fuel ratios can be optimized. Many will say custom tuning unlocks the engines true potential because the standard settings can be improved easily.
VT-VZ LS1 5.7L Engine $700 on the Dyno VT-VZ LS1 5.7L with Over Radiator Cold Air Intake $1350.
VZ LS2 & VZ L76 6.0L $700 VE LS2 and L98 $700
LS1 with non-standard camshaft $900 ($1550 with OTRCAI) LS2, L76 and L98 with non-standard camshaft $900 ($1550 with OTR)
Cam upgrade cars and Forced induction cars usually yield more improvement from what is learned about their characteristics on the dyno. However stock cammed LS1s usually gain very little usually because the settings required to make good power in normal LS1s has been well developed in our base tunes.
Turbo & Supercharged VT-VE V8 Dyno Tuning $1200.

Gen III LS1 Engine VT-VZ Upgrade MAF or MAFless. Cost $500
We can also provide for VT-VY an over radiator intake with K&N Filter and tune to suit.
Gen IV - We have tuned the quickest VE A6 (NA) so far 11.86/118.7mph. VZ 6L L76 & LS2 Engine 6.0L , VE 270 L98, 307 LS2 & 317 LS3 MAF Tune Cost $500 extra $150 for A6 box.
Involves a new improved calibration being flashed into the car - that has revisions in many areas to improve fuel economy, responsiveness and power right through the range. Its then customized to suit the car and driver.
Often an average gain in fuel economy of over 1.5L/100km is the result and the majority of LS1's show an improvement in power of at least 12%.
The Gen IV can be improved further with a full tune especially when its accompanied or preceded by exhaust improvements and an over radiator intake. This is $800 or $750 when done in combination with purchasing exhaust or intake through us.
The Gen IV strongly respond to improvements in exhaust and the air intake strategy.
The A6 can be improved considerbly as well. It can be made to shift much nicer than the stock calibration and with no ill effects. We have some customers cars that have been racing at the strip and driving around for long time with no problems at all.
We are now offering a special on the installation of the top quality Duspeed brand and a mafless dual timing tune together, the prices depend on the model of the car.
VT-VZ 5.7L, VZ 6L $1150 Mafless
VT - VZ with the Monaro Bonnet $1150 Mafless
VE 6.0L/6.2L $1150 Mafless - automatics are an extra $150 for the A6 tune calibration.
For an extra $200 the cars can be tuned on the dyno.
See the webshop for prices for Mail Order Tune packages.
We are a leader in VE model Commodore & HSV Tuning. Customers are travelling from all over the East Coast.
