The dyno is unusual as it is load measuring rather than inferring it from acceleration of a heavy drum as done by the Mainline dynos used in the dyno days over the last couple of years (btw when is the next one in Melb??). It produces a slightly different output so I will discuss with the dyno operator (builder) before posting any figures.
But the object was to compare the maps relative to each other and I got what I wanted.
As expected, all 3 remaps give far more torque at all rpm than stock.
The economy map tails off similarly to the stock while the performance and motorsport maps hold torque for longer so they produce more power. Interestingly, the performance and motorsport maps didn't have a very large power difference but the motorsport map produces a little lower peak torque but at higher rpm so it has a bit more power but better over-rev.
I'll be using the perfomance map at Winton today (at least to begin with) as the earlier torque delivery of this map should offset the marginally lower map power vs the motorsport map that I used there last time. At the Island, the over-rev + slightly higher max power is an advantage.
At the dyno day a couple of years ago, Scotty's TDi pulled about 4kW more than mine with his car running the motorsport map and mine running the performance map (both ChippedUK/Viezu). Switching between the 2 maps on Saturday, my car only saw about 1 kW difference so could the difference on that previous dyno day be due to my car being rather new and possibly 'tighter' than Scotty's well run in engine?
I also bedded in my QPF AR1M pads properly today so they are a bit 'bitier' (noticably stronger than stock even when partially bedded in) and the squealing has gone
