RSTuner Vehicle Weight??

IIRC the kerb weight of a cliosport is about the 1100kg mark.
You can approximate at about 1kg per litre for fluids (thats for water, petrol is less dense (about .75kg per litre)) while oil is more dense.
So at the most you would be looking at the most 1250kg (1100 for the car, 100 for you, 20 for the petrol and an extra 30 for various fluids and other crap floating around in the car)
Though it depends on what you're using the readout for. If you want actual HP, the you'll need the true weight, but if you only want to work out percentage increases, then as long as the weight is always the same then the percentage increase will always be correct.
For example (and these numbers are totally made up) if you put 1500kg in as the weight and got a reading of 200bhp, then make some changes to the setup, do it again and get a reading of 210HP giving you a 10% increase. While the actual power figure may (will) be innacurate, the percentage it has increased by will be correct.
If you did the same runs as above but with a car wieght of 1250, you may get 180 for the first run and 188 for the second, but you will still know that you have an overall increase of 10%

Without meaning to be pedantic. is it not a 5% increase based on them figures?
Whoops :rasp: very true.
Doh, I was quoting 172/182 figures. Should have noticed it was for 197.
Iceberg 172
I would say that's the only reliable way to get an accurate figure if you want to put any stock in the calculations. Too many approximated variables otherwise - you could be miles out.
Question is - how do you get access to a weighbridge? Are there public ones?
