Neat add-on. You may want to pause it at start-up though, because if you happen to have the exe in a directory which contains files or folders starting with "g", windows will just cycle through those very quickly. Maybe it'd also be possible to check which window is currently active and send the keystrokes only if LFS is on top. It might also interfere with instant messengers and the like.
You have to check if the tweak uses "," or "." as a decimal point, otherwise the values will be way off and LFS won't load the car. Open the .twk file with a text editor and if necessary, replace "," with ".".
The set I'm posting could be slightly different since I played around with it a bit after the 7.64, but it should still be good for like high 60's with the right launch. Be careful not to overrev the engine at the start.
You're right, it doesn't, but I figure a V12 is close enough. The W16 has about the same dimensions as a V12, the output matches in terms of torque and power, and the weight distribution is correct, so basically only the sound is different.
There are great sounding V8's, but stock exhaust Corvettes are nothing to write home about, at least not LSx-powered ones. They pretty much sound like any other V8.
VR6's on the other hand have a very unique sound that sets them apart from other 6-cyls. They produce a distinct deep resonance around like 4000rpm that you just don't get from regular V6's or I6's.
I assume a lot of this sound is down to the unequal length intake and exhaust runners of the VR6 head. There are 3 cyls with short intake and long exhaust runners and 3 cyls with long intake and short exhaust runners. So basically you have a 15° V6 with two different sounding cylinder banks, and I guess that would be difficult to replicate in LFS.
