Which dongle do you have? Few years ago, I had basic cheap ELM327 and it worked fine

Just install Petrolhead version and then in Add-ons find Grand Prix update and "but it". App will remember your previous purchase, so it will just switch version to Grand Prix.

i did it several times, its not a problem

Hi Harry, So, you were right. I´m testing it on my company car which is Skoda Fabia 3gen 1.0TSI (MQB platform), and that sh*t box really shows only 69% even on full fuel tank also in VCDS. So Settings for HLT are correct and ussable, tomorrow I´ll test it in my older Octavia II RS. next step is oil ...

Harry, My apologies. I dont had any bad intentions about "hijacking" other topic. I just don't wanted to start another thread for almost same thing. I´m moderator on other car forum, so I know how messy it can be. Back to my "problem". I´ve tried it several times, turn engine off...

Ok thanks, I´ll try it in car and then I´ll give you feedback

just like that? Im not sure about Mode, which I should use 21, 22 or 23

thanks, and what about syntax of formula in HLT? for example for fuel imput is it 100/255A (see on picture). So how I can set it in HLT? like =(100/255)A or just =100/255A or any else option?

Hi Harry, according to this page https://en.wikipedia.org/wiki/OBD-II_PIDs its possible to set fuel, EOT or brakes in custom PIDs?
