And one more thing. I think that it would be useful for hobd user function which let to reset counter (km counter) when change oil.

I used EL coefficient 3.5 for my Mazda 5 (105 Kw diesel) and I put full tank and run with hobdrive always on all the tank. Hobd shows 7.3 L/100 km, and I get 7.1 L/100 km. It's very good I think. But usualy my speed is until 90 km/h (about 1500 rpm). But when speed increases under 90 km/h and more ...

I am not sure if you understand what I wanted to say. Is there a possibility to install HobDrive function, which recommend when shift gear. For example from 5 to 6 and so on.
Thanks for answer.

Is there a possibility to insert Gear shift indicator in to Hobdrive?

I'm not sure, but maybe these data are suitable for the calculation of fuel consumption

I wanted to ask whether it is possible to calculate the fuel consumption by diesel injectors? (diesel engine is a direct injection (car MAZDA 5))

First of all sorry for my English language. Hobd program I re-installed it as many times, so in that file you does'nt find the necessary information . If you could send me HOBD old version that was before 1.1.27 update (approximately 2012 January) I could install it and try on my navigation. and ...

Yes I can. but I was reinstaled several times.

I tryed standart (car) with ELM int (custom)

Diagnostic was working somewhere at the beginning of 2012, then I first try HOBD.
sorry for my English

I remember that diagnostic was working in old version HOBD. But after adding Nissan custom it don't work.

I wanted to know how things are going with mil code problems. I tried the latest 1.1.51 version of HOBD, but it still not working diagnostic.
Thanks for the answers Cail.
