On the former discussion: LapTimer v23 had a bug for custom PID requests in the Android implementation. It should be fixed for v23.0.1.

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?

Here is the full syntax for expressions in LapTimer:
So you better use "=100/255*A". Brackets are not required, evaluation for a <term> is left to right.

Code: Select all
formula = [ "=" ] conditionalexpression
conditionalexpression = equalityexpression { "?" equalityexpression ":" equalityexpression }
equalityexpression = relationalexpression { "=="|"!=" relationalexpression }
relationalexpression = expression { "<"|">"|"<="|">=" expression }
expression = [ "+"|"-" ] term { "+"|"-" term }
term = exponent { "*"|"/" exponent }
exponent = factor { "^" factor }
factor = parameter|number|"(" conditionalexpression ")"
integer = "0"|...|"9" { "0"|...|"9" }
number = integer [ "." { "0"|...|"9" } ]
parameter = "A"|...|"Z" { "A"|...|"Z" } [ bitqualifier ]
bitqualifier = integer

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

You will need an ECU selection at least. Formally that's fine otherwise, but I cannot comment on any custom PID setting for Skodas.

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

Do you have a valid source for Skoda PIDs? Which one is it? Please keep in mind that custom PIDs are different for every manufacturer and even model. So you can't use a custom PID spec from other cars.

Unfortunately I dont, I spent several hours to find anything but without success. Or, its possible to use VCDS cable and SW (I already have it) to dig some info about it directly from car?

Hi Harry. I´ve tried to check oil temp via VCDS and I can see correct value. Can I use VCDS data to find optimal PID settings for HLT? Or it´s nonsense?

I have no experience or insights into the VCDS tool. Someone else to help?
