Nowdays I test with limited IQ setting on the program itself. So I have a test ecu programs like 15 mg of injection per stroke on the a4b6 1.9 tdi is about 4 liters of fuel consumption per 100km/h and on 3 cylinder engines it is 3 liters. Program activates when you floor the gas pedal so it works normally on all other positions so its more easier to get to your start speed when you start testing.

This is even more accurate as the map changes if rpms change a lot on a hilly route etc. This way you get even better results when testing different boost, start of injection, torsion value settings. You can also do sweep accerelerations in same way like I have also done. You have different settings for different rpm and each IQ settings levels.

With the constant IQ setting you measure again the time for certain distance and from the time difference you can calculate avg speed--> from that you can calculate the changes in efficiency or drag reduction.

As always when testing drive the car first fully warm before you start measuring. On my diesels 50-100km depending on weather.

At the moment I can say my programs for 1.9tdi, 1.4tdi and 1.2tdi are pretty efficient as I have tested all those settings individually which is most efficient settings for each value. I can sell my programs online if somebody is interested send me email.
