Just purchased 2015 TDI and wondered if anyone has used this chip and if so what were results
They are very impressive figgers it must be a blast to drive, just curious if you live in Brisbane how come you got the tune in Perth? I have contacted UFI and they wanted to splice the wiring harness and fit 2 of there tuning boxes, is this what you had installed and what was the cost if you don't mind and how long have you had them. I have a Malone tune on mine and i have a small issue but they wont communicate with me. Regards Vaughan.I've got Tunit boxes on my R50. More power and torque at slightly better economy. Dynotest is attached. I run it on the maximum setting all the time as the economy gets better the higher you set it. On my car anyway. I haven't had any issues with them. Not sure if they are available in the US.
Don't fool yourself. If you want economy, drive slower. The engine is already tuned for best economy.
If you want more power and you chip it, then more fuel is added. Sometimes remaps will up the boost as well.
I had a chip and saw the oil temps shoot up by about 10-15 degrees celsius. I sold the chip.
The really cheap plug and play chips is a parralel resistor on the fuel temp sensor. It fools the ecu into thinking the fuel is hotter than what it actually is so the ecu injects more fuel to compensate (as hot fuel is less dense than cold fuel). More fuel = more power.
My advice : just leave the thing alone. It's not a supercar and it's by no means slow for a 2.5 tonne SUV.
