Can you explain what the two sets of lines are for? I'm guessing the top set is KW power. Is the bottom line Nm or A/F ratio? The numbers on the side read AFR (air/fue ratio?).

Thanks.

Good work topgear,
Its good to see a genuine stock output at the treads for comparison, most people don't bother. The only one I found on this site was in the supertune article in the tech section..... just under 40 hp at the treads after the 'Supertune' and 25hp beforehand

40 hp is about 30 kW, so perhaps the old girl wasn't as tired as you thought

Have spoken to a lot of tuner friends, they all say that what ever you get in KW atw you double and get engine horsepower. Its not exact but they so its so close your not lying if you use this method...

Therefore we have around 60hp, they had 69std, a loss of 15% (9hp) over time is pretty accurate dont you think...??

The power line is crazy because its when the secondary vacuum butterfly starts to open. tried dynoing with the vacuum butterfly tied open. It makes less hp and runs crazy rich down low. So for anyone thinking that it makes the car go better, trust me, it doesnt, might sound a bit better though
