How? do you have an evoque to work on somehow? I would have thought it would be similar to mapping a freelander which can be done but who knows what effect any extra electronics/software might have.

I don't need the car at first I only need it's software calibration file which I have. Once I have this i can Start work on the tuning and them move on to the car when available to finalize.

RE: Engine question ... Td4 sd4

Guys....take a look at http://www.tunit.com diesel tuning, typically 20-30% increase in power/torque.
Evoque made the listing of available products already.

RE: Engine question ... Td4 sd4

I already have one of those tuneit boxes here. I am puzzled how it works on an SD4 , I cannot find a remap listed for an SD4 yet

If an SD4 is just a remapped td4 surely if you remapped both engines they would produce the same power ?

RE: Engine question ... Td4 sd4

Just checking, Didn't somebody mentioned that Td4 has a single exhaust (vs Sd4 having two)? If that's the case, would that not mean a different exhaust set for the two, which could translate to different power figures? Hence other thgs which could be different - apart from the fuel maps, different sized turbo manifold, different fuel rail pressures....

-----------------------------------------------------------------------------------------
How does Tunit work?
All tunits are specifically designed to achieve enhanced diesel performance and economy by modifying the fuel injection parameters of the engine. Only by the careful interplay of these values and characteristics can the optimum performance of your engine be achieved.

The tunit does not over-fuel the engine or adjust boost pressure. All enhancements are safe and work within the engine’s own safety parameters programmed into the ECU. This means that the tunit cannot damage your engine and works with the manufacture's settings to achieve maximum efficiency.
------------------------------------------------------------------------------------------

Looking at that description, this means it works by modifying the diesel commonrail pressures. Which means we can still upgrade the diesel fuel pump, air intake (K&N anyone), change the AFR maps, change the boost pressures, (and if its electronic throttle) we can change the throttle response. Tuners might able to do this once the Evoque comes out, and it sure will be interesting stuff to look out for (esp for the power-hungry) Smile

RE: Engine question ... Td4 sd4

It's all possible, but only by bench mapping, evoque will almost certainly have edc17 ecu which can't be mapped through obd port

RE: Engine question ... Td4 sd4

Just checking then to upgrade £1000 to an SD4 is a waste of money as someone can just retune the TD4 to an SD4 performance pretty easily?

If someone could confirm as I am currently debating the TD4 v SD4
