Engine Mapping and Dyno Tuning

Vision4 10Competition Systems offers a comprehensive custom dyno tuning service for all types of competition and road going vehicles with over twenty years of experience with OEM and motorsport engine management systems.





A Competition Systems dyno tune is not just a full power run but a complete engine calibration with the intention of maximising your engine's performance under all conditions. Our in house chassis dynamometer or engine dynamometer is utilised to provide you with the best result for road or track.

We have experience tuning a wide range of competition engines including

  • GT1
  • GT3
  • Formula 3
  • V8 Supercars
  • Australian Rally Championship
  • Australian Production Car Championship
  • Improved Production (IPRA)
  • Historic open wheelers (including turbo F1)
  • Superbike

Engines we have mapped have gone on to win an Australian GT3 Championship, Australian Rally Championship, several Island Magic GT enduros and Targa Tasmania. Our experience also stretches to an even wider range of motorsport engine control units (ECU's) including Magneti Marelli, EFI Technology, Motec, Pectel, Haltech, Nemesis and Microtec (Italy).

Our range of expertise also includes Individual Throttle Bodies (both NA and Turbo!), Drive By Wire (DBW), variable camshaft systems and traction control mapping. Having been the original importer of Jenvey throttle bodies for many years, we have a lot of experience in mapping multiple throttle bodies with excellent results from daily driven street sleepers to track animals.

 Located in Carrum Downs, Victoria, our workshop is readily accessible via Eastlink.

LGN843 InitialVsFinal

Renault 12 Gordini Heritage throttle body conversion

This little guy really surprised us. The initial green run is on a pair of 45 Webers with electronic ignition. The red run is after a conversion to Heritage EFI complete with Emtron SL4 ECU, Competition Systems distributor and 45mm Jenvey throttle bodies.

It probably would have gone further but we suspect the valve springs are a little soft after all these years!

ECU - Emtron SL4 with Compsystems Classic Throttle distributor.

Intake - Jenvey TBP45i's with stock cold airbox

 GTP040 Initial Vs Remap

RF40 with a stroked 347 Windsor, Motec M800, eight stack injection and bad manners.

Came to us as a beautiful, but undriveable, example of an early Roaring Forty GT40 replica. The throttles were unbalanced and the mapping couldn't decide if it was rich or dangerously lean. After some airflow balancing and a thorough remap, this bronze beauty drove like a pussy cat.

ECU: Motec M800

Intake: IDA throttle bodies


Megane RS265 CAT5506401


Renault Megane RS265 remap with mild CAT Cams.

One of our favourite Euro Hatches really came alive with a set of mild Cat Cams and an ORECA GrN exhaust. After a remap of the stock SAGEM ECU, the results speak for themselves.

ECU: Stock SAGEM 300

Intake: Stock with standard turbo

Exhaust: ORECA GrN with high flow cat.


Dalrick 160607 Final


This was an odd one. A Dalrick Clubman with an SR16VE Nissan engine and an old Wolf 3D.

Haven't had to use a hand controller for a long time!

ECU: Wolf 3D

Intake: Jenvey TBP45i's


Check out this link for an update on this car, now with Emtron SL4 and lanuch control.


VROK InitialVsFinal 150213


 Renault Clio 197

Better top end performance and mid range torque.

ECU: Stock SAGEM S3000

Intake: Stock


LP600GT3 077 150204 InVFnl


Lamborghini LP600GT3 before and after.

It's hard to squeeze any more out with limited compression and 43mm inlet restrictors. The biggest advantage was superior traction control mapping and drive by wire calibration.

ECU: EFI Technology Euro12

Intake 2 X 43mm restrictors

LP600GT3077 102RON Remap

What difference is their in 102RON? Lamborghini LP600GT3 before and after.

High compression, restrictor plate engines love high octane fuels. And fuels don't get any better than ETS Extramax 102RON.

This one was mapped completely for either fuel. Guess which one the driver likes?
