Conversion from g/s in VAGCOM to bhp

[Al]

Hi peeps. What is the conversion from g/s to bhp in VAGCOM? From the searches I have done, it seems to go from a pessimistic 1.2 to an optimistic 1.3. Is there a definitive answer or is it just approximate?

For example, 200g/s would be either 240bhp when multiplied by 1.2 or 260bhp when multiplied by 1.3.

1.38 ish is pretty much bob on.

logged while on dyno, then logged on the road.

so if this cant be affected by happy dynos/operators... is this more accurate way of calculating bhp?

or are mafs just as unique?

1.31 works for me. But i would defo say that 1.2 is a bit of an under estimate.
It would be interesting to see what a new stock cupra logs.

Thanks guys. However using these figures, that same car is;

200g/s x 1.31 = 262bhp
200g/s x 1.38 = 276bhp

I wonder if Ross-Tech could explain?

not likely... it's all a rough guess anyway.

hello there please help as i am going to get my car remapped but i dont want to have to buy a maf.

my reading is at 183g/s is this about right for just a twister induction kit with no pipe down to front of car and if i were to fit a pipe to front of car would or should this increase?

thanks

183g/s on an ibiza with k03s is good.
