This is our most popular choice of tune and usually results in a considerable gain in performance and overall fuel economy.

Dual timing table mafless tunes are now available for cars with the VT - VE Gen III./IV  engines at a price of just $550.  If its an Auto 6 spd this can also be tuned for better shifts for an extra $150

These are done using a new custom operating system made by EFILive. The usual Mafless tunes which are based on the VT-VY HSV GTS tunes calibration are only able to have the lower timing table as active. This gives less ability for the engine to be protected from regular low level knock. The use of an upper and lower timing table provides the added benefit of the car being able to learn its way upward and downward rapidly between the two spark timing tables adding engine protection and also better performance in varying conditions.

 The Custom Operating system also has added tables;

• Improved  temperature correction of the air fuel ratios.
• The ability to specify air fuel ratios at any rpm and manifold pressure.

 
The Base Tunes have been optimized for much more than just wide open throttle. They also contain some special calibrations that usually provide a considerable improvement in mid range power and fuel economy. 

A recent customers LS1 Manual made 255rwkw (317 engine kw) on a dynolog dyno with one of these upgrades.
Pretty good for a LS1 with an over radiator intake, ported throttle body and metal cats. Still having the stock balancer and stock valve springs.  The car has also been returning great fuel economy. Better than 30MPG on a trip.

A customer Peter did 12.98/108mph in his VY SS auto at WSID, its only modifications to support the tune was that it had an over radiator intake and a good exhaust system. It even had the standard diff gears.  His son Steve beat his dads time with a 12.63/111mph in his VZ 4 speed auto LS1 stock cam, stock converter. It just has 3.9s, full exhaust and an over radiator intake.Recently both Peter and Steve have changed the cams in their cars and are both regularly in the 11.6s/116mph standard.

The fuel economy record on our basic mafless tunes is 816km to a tank. Paul from Gosford did this in his VY SS ute which is a M6. Its was around 8.2L/100km for the trip from Gosford to Canberra and back, to of all things the Canberra Summernats.
Many of our customers cars can get in the 8s/100km M6 or 9s/100km A4 on a trip and we also have some inner city customers who have reduced their fuel economy from 20L/100km to 13L/100km.

VE Commodore Gen IVs all gain heaps in their throttle response and part throttle torque meaning 6th gear can be used at a lower speed and they improved in economy. They also gain on the dyno by around 20kw at the wheels from just the tune.  We have seen a few L98 270kw VE manuals make 289 kw at the wheels from minimal mods including a full exhaust upgrade and a quality over the radiator intake from Duspeed.  The same gains are apparent in L98, L76 and LS3.  We have seen stock cammed LS3s tuned to make as much as 311rwkw and our own Grange is making 302rwkw as an automatic while still retaining the stock camshaft.

We also have done numerous AFM equipped L76s and can advise on smart exhaust mods for them. They are able to be tuned to improve even further in economy because we tune them specifically in AFM mode in addition to the performance adjustments.
