Was a bit bored that some bots took so long time (or crashed after a while) so I made one bot out of two instead. I like tweaking, it's part of my real-life job.
So how about 1M IGC, 500k+ rep and 10.000 km every hour?
I use NFSW Multihack SilverAngel together with the macro-software Easy Macro Recorder, both are linked here in this forum. The macro-reader is not a bot itself, but when used as third-part software to automate your gaming then it's a bot.
Hastings Circuit is 30.12 km long and that's the only reason I use that circuit! Available at all classes after you done the first two mandatory races!
You will not be able to see reputation or IGC-increase until you visit driver-screen or relog game. But you can still see the achievement-counter in upper left corner.
These numbers are with amplifier-bonus at level 50+ and remember that exp. gained increases with level.
6 races per minute or 360 races per hour!
532.080 experience/hour (at level 52) (you'll be 60 in like 12 hours or so, achievement "Payday")!
1.080.000 IGC per hour!
10.843 km/hour (damn, that's a fast car!!)! Completes "Long Haul" in just 4 hours.
But, use at own risk. This shit is wild, and on steroids.
I also managed to create a quick one for pursuit, painting and vinyls aswell.
First video (lame setup video-guide, I know)
For this you need, as already mentioned the software Easy Macro Recorder and the hack SilverAngel NFS World Multihack and enable "Auto finish".
Tested and configured one to work with GMZ trainer aswell, if you don't want to use SilverAngels hack.
Read the guide how to create your macro in Easy Macro Recorder. Manage the in-game windows so it's easy and fast to click around (don't use keystrokes, only use your mouse/mouseclicks).
Took a few tries to get a good loop, so be patient. Personally I recorded a slow one, and changed setting in EMR to playback fast instead.
Don't set it to tight, sometimes it takes 2-4 seconds longer to start a new game, at least for me.
About setting up the hack? There is no setup. Just download and enable "Auto Finish".
Have fun!
