Text Box: Vehicle Technologies Australia (VTA) specialise in re-programming the Holden Gen111 & Gen1V engine management computer maximising engine and transmission settings (auto) for optimum performance using the latest  software. The following packages have been developed and extensively tested on our development vehicles and then used in our customers vehicles.

                           STAGE 1 PROGRAM UPGRADE VT-VY    UG591  
Up to a 7% improvement in  fuel consumption, increased performance and responsiveness, this tune will reduce 1/4 mile times by .5 seconds, no other modification for the price can achieve this increase in performance. Either unleaded or premium unleaded fuel can be used. 

                           STAGE 11 CUSTOM  TUNE VT-VZ    UG593
The “Universal Custom Tune” this tune is for those performance enthusiasts that are interested in a considerable improvement in performance and fuel consumption at a reduced cost it achieves around  85% of the performance and  fuel consumption improvement that a full custom tune would achieve and represents excellent value, this upgrade includes a data log session to confirm operating parameters for the given vehicle are met, premium unleaded fuel is recommended. This upgrade is equal to your typical Dyno tune at a fraction of the price.

Typical Performance improvement: 
Standard tune 14.9 seconds ¼ mile 
VTA Upgrade tune 13.8 second ¼ mile 

Based on our development vehicle a VY SS Ute 21000ks at WSID using 98 octane fuel , absolutely standard including street tyres, standard exhaust system and induction system. 

         STAGE 111 FULL CUSTOM TUNE  VT- VZ  UG596
A VTA developed base tune is downloaded into your car that has been developed at WSID and under actual road conditions for optimum performance and economy this is then data logged on the road and re-programmed to suit your vehicle ensuring that not only is there a substantial increase in performance but the vehicle feels responsive under all operating conditions including auto transmission operation. Overall a high performance level is achieved with a broad responsive feel with the added benefit of reduced fuel consumption at around 12% over the standard tune under the same operating conditions. The vehicle is required for a minimum of one day, premium unleaded fuel is required. 

Typical Performance improvement: 
Standard tune 14.9 seconds ¼ mile 
VTA Custom tune 13.6 second ¼ mile 

Based on our development vehicle a VY SS Ute 21000ks at WSID, absolutely standard including street tyres, standard exhaust system and induction system . 
STAGE 11 & 111 tunes are available in Speed Density (mafless) at no extra 

 Nitrous Oxide System NOS
This is comparable to an athlete on performance enhancing drugs, it does work and is relatively cost effective however it is illegal to operate a vehicle on NOS on a public road In Australia therefore NOS can only be used on the race track.

Vehicle Technologies Australia can supply and install  NOS with an upgrade of your engine management system to a full custom tune both for the road and the track with a custom operating system allowing fine adjustment of the custom tune program to accommodate optimum performance on NOS at the track. If the customer prefers to buy and install the NOS system then VTA can supply a custom operating system and a full custom tune.

NOS usage costs, with two 1/4 mile runs one 10.9 and one at 10.8 used 4lbs of NOS. With a 10lb capacity cylinder and a fill cost of around $140 this equates to around $28 per 1/4 mile run. Given the cost of supply install and tune of a NOS system giving a 1/4 mile reduction of 1.1 second on a 11.9 second car It would not be possible that this result could be achieved by any other means for the cost.
