I feel like this is probably a good place to share, with A2’s being fairly economy optimised as they are. I’m hoping to collect some data using the most “standard” set of conditions as I can on how various ECU adjustments affect economy. This information is all going to be in relation to a 1.4 TDI fitted to a Skoda Fabia, using standard EDC15 management with an wastegated turbo.
The main things I’ll be focussing on is adjusting SOI, EGR and boost calibrations around the part throttle cruise region. From the factory, the ECU has to compromise between NOx, soot, CO2 and economy. Now in the aftermarket world, we can forget about 3 of these (environmental concerns are another topic, this is purely for research purposes)z
I’m not a tuning expert, nor do I have dyno, but hopefully some people can learn something.
