ORDC prep = badger pesters me, i do a basic tune for stabilty, tweak and then save it.
If i catch BladeRunner or Badger on during the week we might have a little lap around a championship track and tweak.
Sometimes as per round 1 Badgers first outing in the car is qualifying
I like the tuning part and as long as I lap well for the tune I am happy. I love the dueling for a clean pass and I love lapping fast to catch a gap - often race lap will be faster than practice so the competition really makes the tuning worthwhile. Otherwise I only compete against myself
Generally it takes about 10 minutes to tune the basics and an hour to get it nice for 90% of tracks.
I use an old feuerdog base setting calculator from android market
but I find the diffs a little off and the roll bars far too hard (but the right balance)
But I know the basic balance of FM3 pretty well and apart from a few tweaks to some cars and the amount of effect ARB and springs have most of the time the tune I save in first out of my head is pretty close to the ones the various sheets recommend - i tend to run a little stiffer than they suggest and use a fair amount of off throttle oversteer on the rear differential which helps me hit apexes albeit at the cost of a little speed. but the consequence as you may have seen is that hitting some kerbs can be disproportionately serious. So no tune is perfect for everyone. I cant drive most of badgers tunes but he laps as fast as me when driving a shitbag so cojones seem to be >= tuning (at least at my level). And seeing as people who say they cant tune appear to be able to ride far worse set ups and kick my ass I need all my tuning skill to make up for balls out racing.
Less time is spent tuning if you don't have the race gearbox because then you only need to tune final drive for the worst corner and dont need to back to back time test different gear options as much. There is a tuner calculator in the Forzamotorsports forums which is good for base tunes but has a really good gearing calculator - that saves a mahoosive amount of track time but may not be to everyones taste.
Some say its cheating to use spreadsheets but I built my own for Gran Turismo and FM2 and FM3 so I reckon I didnt slack on effort. but the rate at which the community develop theirs was simply outpacing the time I could spend so I appraise whats out there and use and adapt bits from each
The day job is Excel and analysis so it fits nicely with skills i need to keep on top of anyway
They arent a magic bullet but if they give you a stable platform you can feel what might need tweaking and adjust to suit your style/preference
But the time spent in tune shoppes means that unpestered Paintwork would be plain white with the Imperial symbol i have.
Then I can waste hours reminding myself how badly I know my way around the paintshop
