How does vems get info regarding the consuption in l/100kms?

Probably something like Injector Flow Rate(BaseSetup->EngineSetup) * Number of injectors * Injector Dutycycle / Road Speed.

but mine on 1.1.27 at the moment does not have any road speed input!

Upgrade ;)

i have an old V3.3 does it reads the speed signal? P259 dont show anything. running on 1.1.81 now

P259 shouln't "show" anything, it's an output and has nothing to do with wheel speed input.

V3.6 comes with wheel speed input, best to send off to Budapest for upgrade unless you have the right skills and tools.

Skills and tools are there....i need a guide.

Something tells me though that it will not be an easy task.

i bought my vems in 2009. It has version 1.1.27, and i am now waiting for a new ECu unit with a few upgrades i have requested,

i posted this because i wasnt expecting any reading from the fuel consuption, as speed input was not there back in 2009(or so i knew)!

it is weird that i do get a reading although still on 1.1.27. Does this mean that it is of no use at the moment?

The fuel consumption always works, but can be based on rpm - which means the gauge is calibrated for a specific gear (cruising, maybe 5th gear). I can't say right now how it's done.

no worries
the new ecu is now almost ready to ship!

obviously the speed sensor now that i have upgraded needs a PID control!!

my car spedoemeter which is where the sensor is getting it's input is working fine. Always has. The sensor it self on Marcel's guide picks up the proper signal that shows the km/h, but then jumps around constantly when accelerating. Mostly upwards on the gauge. I doubt i would be able to use the consumption or gear depended boost with a jumpy signal like that.

How difficult can it be to get a proper reading when VEMS is able to get a signal from the speedometer which works fine?

+1 problematic roadspeed signal, with good working speedometer

i hope this can be tackled by the developers as it seems to be a good choise for boost as well.
