Re:


For the petrol you would need a piggy back ECU, but I doubt anyone fitted them to their T31 petrol as yet. Do a search for piggy back ECU and you will see the ones for the T30 model (same engine).

Re: T31 ECU


I fitted the unichip from Dastek in South Africa which is a piggy back. I had it setup/tuned for fuel consumption. The day the dynatune was done, it was 32°C. Improvement in power was 9.5% at 1500 rpm, 7.7% at 2000 rpm and overall average increase of 6%.

I got 10.8l/100 km over a distance of 10 000km before fitting the Unichip from Dastek. Fuel consumption improved after installation of the chip. Now I get average 9.8l/100 km over a distance of 12 000km. Most of it is done in city driving which averages at 10.4l/100 km and open road/highway 9.3 l/100 km. Best open road was 8.1 l/100 km driving speed at 120 kmph.

Should the chip be set for performance, the gain will be more. I am happy with the low down power gain. The car accelerates far smoother than before. It was worth it. I paid about 300 AUD.

Re:


We have covered the Unichip in the existing T30 thread HERE and the way I see it based on previous experience is that it is useless to fit a piggy back ECU if you haven't done any performance modifications to the car, as the factory ECU is designed to handle all minor performance mods like an exhaust system upgrade...etc.

To use a piggy back for the sole reason of saving fuel is a waste of money, as that is not the primary purpose of the piggy back ECU.
