Is it a bit accurate? You know you're way with electronics :idea:

What did you use as input signal?

Wow!! dit you have technical details about it. 1 want to now how that thing the fuel consumption knows?????

kaczart · Posted: Sat Jan 22, 2011 8:49 pm

speed is exacly the same like GPS (from original VSS - vehicle speed sensor, rescaled)

fuel consumption is +/- 0.3l for 50liters (it's counting impulses from injectors, accuracy is 0.1ms per cycle)

it's home made, maybe i'll do some for trade, dont know ;)

You only count the pulses? Inject time vary with rpm/speed/load does your mod use the inject time(it must be or else it can not be accurate)?

Microcontroller counts width of pulses with 0.1ms accuracy. You need to know also a injector const (about 0.003 l/s) to calculate real-time and avg. fuel cons.

Take a look at pct:

Top work

Always wanted one of these after I saw the first version you did

added some new functionality to onboard computer, but still need new inspiration... have u got any ideas what else can i add to it ? :)

I'd like to start up with production of it (in few months) .. it's now universal to any car with electr. injection.

ps. my new zx wallpaper http://www.klub.citroen.triger.com.pl/i ... d82824.jpg :p

last photo is fuel tanks (i have pb and lpg in car - lpg in PL is twice chipper than pb)

Engine load. Maybe you can take a signal for it from the throttle position sensor, Exhaust temperature. I like your project. I think a want some of it in the futere ugeek

How about battery voltage + CO2 value? if possible 8-)

great work!

what about data from lambda sensor.. air/fuel ratio in the exhaust..oxygen..
keep updating! ugeek
