A first in Australia, LS1Edit allows us to directly modify the software in your 1999 - 2003 onwards Gen III Holden Engine Management System (PCM). Unlike the chip tuners that hack at your computer with a soldering iron, we plug into your diagnostic port and 'flash' in a new program. Quick, seamless and able to be reverted to stock if needed. LS1 Edit does not require you to pull the car apart to get things happening.. !!

From the factory GM very carefully calibrate the LS1 engine management to restrict power. They do this for a number of reasons, but the main one is to give them a growth path with the engine over the model cycle. Why give the stock 260 - 270kw of power now when it can be slowly phased in 10kw at a time with each new model update? In most cases removing the limiters and tuning the tables correctly not only gives more power but also improves economy
There arent too many new car dealers that will officially condone modification of your new car. There are however a few that dont mind the advantages that LS1 Edit can give, particularly in cars that are there to be driven by the public.

With LS1Edit software we can modify the following parameters to get peak power from your engine, on our state of the art chassis dyno: LIMITERS: four Idle Speed Tables Five RPM Limits RPM limit By Gear Table RPM Limit by Temperature RPM Limit Delay
FUEL: Fuel Air Ratio Table Volumetric Efficiency Table MAF calibration Table Fuel Pressure versus voltage Fuel Injector flow rate Manifold vacuum Fuel injector Offset Table Power Enrichment vs Temp Table Power enrichment versus RPM Table Wide Open Throttle Hot & Cold Tables Closed Loop Enable vs Temperature
