Can you explain to me how a box wire 2 plugs, and about 5 wires going into it, can properly manipulate ECU signals that a proper remap would alter? What about drivers wish, smoke maps, injection maps, boost duty maps, torque maps, Boost limiter maps, IQ maps, MAF sensor maps etc etc. You get the idea.
Not saying they dont work, but they are still a crude way of making a car quicker, by fooling or manipulating signals to 2 sensors on the engine. I believe these are the rail pressure sensor and the boost duty sensor.
What happens when the box increases boost over the overboost threshold and the ECU sees this via the map sensor and begins to add ECU level interventions to start to protect itself?
Regardless of how far box technology has come, in my opinion, they are still a VERY expensive (£370) and poor way to get increased performance. For that price, you might aswell take it to a proper company who specialises in remapping the VAG range.
All just my opinion based on what ive learnt over 7-8years tuning and also remapping cars at home myself and teaching myself what to do and what changes affect other areas of the mapping/vehicle performance. A decent map will change upwards of 30-50maps to get a performace map with a proper OEM feel to it and at the end of the day, safe. You aint going to get that manipulating 2 sensors.
