Hi friend,

I know it´s a bit late for this post, but here we go ...

I was making some experiments with my new Opel Corsa (Brazillian version - small 1.0 litre engine - 79 Hp)

The car is good, but I don´t use gasoline, but Alcohol. The performance is good but the consumption is very high,
specially on heavy duty or high speed.

I did a small "on-board" (with lot of help from this forum) computer for my old Opel Corsa, but without Fuel Consumption display.

Now, i Would like to implement that function.

I Did some search on internet and I foud this :

Don´t worry about the display. This display is just an I2C module made for GM/Opel cars, like Astra, Corsa Meriva etc.

They are monitoring the Car´s speed sensor and the Injector´s "on-time"

My doubt is : do you think the method used by the author really eficient ?

Did you have some progress on implementing the GM VPW ? (i´m still trying with an old GM´s corsa ECU on my desk - but with out success).
