Who has done ANYTHING with success along this topic?
Depends on what you call succes.
On a 1999 turbo diesel I was able to increase fuel efficiency with 6% measured over approx. 30.000 miles. Also the emission cleaned up to the extend that the MOT thought it had a gen 4 cat.
Same pattern on a 2006 VW/Audi 2,5 TDI. Approx 6% improvement in fuel efficiency and emission so clean that it could pass a Euro 5a eventhough it is a Euro3 spec engine. I got the car at 189,000 km. Now 385,000 km and counting.
When you cover something like 45.000 miles per year even 6% savings on the fuel begins to add up, but just as important is the emissions. I am not even close to run in to problems at the inspection. My biggest concern is that the car will soon be banned in larger German cities due to the fact that on paper it is only a Euro3.
Both cars had increased power. The 1999 TDI was tested at 267,000 km. to 127 hp & 270 Nm. At 502,000 it was tested again and showed 136 hp and 285 Nm.
The 2,5 TDI was tested at 190,000 km to 189 hp and 385 Nm. Got a new pump at 345,000 was tested again with the new pump and with the HHO on, and pulled 204 hp/400 Nm. Same day we tested it with Vpower diesel and HHO and got 212 hp and 410 Nm. I did not test it without the cell.
The advertised 20-30% I never got even remotely close to, but I also did not modify the sensor signals apart from 10% on the Nr. 1 O2 sensor.
