These are not simply an add-in chip but a complete retune of the fuel maps and ignition timing (where applicable) for maximum efficiency using modern fuels and real world conditions.

Syntek spent years developing these custom tunes and recalibrations. These have been performed on our own vehicles and as such have been tuned for maximum efficiency. Original factory tunes assume that vehicles have to be able to use low quality fuels and run in very hot and tough conditions (Lowest grade gasoline in the US for example was typically 80 octane). Hence they were never an efficient tune and do not suit local fuels (eg. 91 octane ULP in Australia). Syntek recalibrates the ECU fuel maps and timing curves to suit modern fuels and typical Australian conditions. Typical improvements usually exceed 5l/100km reduction in fuel consumption. Powerand drivability are improved giving the ideal balance. Emissions are often improved once the engine is correctly tuned.

Real world case

Discovery 1 3.9 litre V8

Engine left untouched apart from ECU remap and ignition timing regraph.

Original consumption 25L/100K city driving
After conversion 17L/100K city driving

This is a saving of 1600 litres per annum at 20,000Ks per year driven. Financial saving of $2,400 per year at $1.50 per litre. The price of the conversion was recovered in under 2 months. Performance improved noticably and the vehicle emits approx 1.28 tonnes of carbon less per year. Savings could be greater as the highway consumption dropped to 15L/100K.

Real world case

Discovery II TD5 Turbo Diesel

Re-tune of ECU and adjustment of turbo wastegate.

Original consumption towing 14L/100Ks
After conversion 8.7L/100Ks

Power was increased by 25% and torque by 30%. Performance improved noticably with less turbo lag and mid range torque. To quote the owner "We towed the campervan to Mount Warning yesterday and hardly knew we had anything in tow. What a great difference your adjustment made. On refilling the tank with 35.50ltrs for 312.20 ks, it worked out at 8.794ltrs to the 100ks. I don't think that can be improved on, do you?".

Real world case

1997 5.7L MPI Chev truck

Re-tune of the ECU only.

Original consumption towing 27L/100Ks
After conversion 17L/100Ks

This vehicle tows a 4.5 tonne gooseneck mobile home/trailer. GM never tuned these vehicles accurately for such a heavy loads or for modern higher octane fuels. Ignition maps were re tuned and cruise fuel mixtures were set on the road whilst towing. Power unladen was increased slightly but low to mid range torque was raised to suit the towing. Fuel economy improved by 37%! The surprising improvement comes about because the vehicle was never tuned for this kind of work. This resulted in gross overfuelling when towing. Most petrol engines doing heavy towing respond to this tuning.
