FITT Transmission tuning challenge
This is a quick challenge to finish out the year and not interfere too much with the year end holidays.We will be using a prebuilt car, @ImToLegitToQuit
RE Amemiya RX-7 the following settings have been changed to better fit the car to Grand Valley East.
LSD 9/8/10
Aero Front 150 Rear 280
Tyres Sport Soft, (consistency and removes any worry about spinning, this is supposed to be low stress
)These changes have been approved by @ImToLegitToQuit
All participants should be be familiar with FITT standardized rules
The track that all tuning and testing will be done at is; Grand Valley East
Time line
Dec 8th-15th Tuning of the transmissions.
8th-17th Testing
Tuning rules
5 of the 6 gears must be changed by a minimum of 0.010 from stock values for the Final drive and Top speed slider setting.
The Final Drive doesn’t have to be changed but that is encouraged.
You CAN NOT use the transmission that @ImToLegitToQuit built for the car. *yes you will need to rebuild it for the challenge Tolegit if you tune for this one*
Due to the highly compressed nature of the challenge and the time of year, Once you submit your transmission it’s FINAL typo corrections are permitted.
Testing
Go ahead and build the car and start putting down laps at GVE to get yourself familiar with the track and car combo it’s not changing for this challenge. Once a Transmission is posted test it, it’s final.
Although not required I would like to ask testers for a base lap time using the stock 5 speed transmission, for future use and to use as a tie breaker in the event of a tie. The most improved transmission would win. A base lap will also give you a feel for what the custom transmission has done for the car which should help a bit wit the DC scoring of this event as the car is not changing.
As for your DC score, as always its a preference score, but this time it’s focused entirely on the transmission of the car, example things to consider;
did the acceleration improve, how was wheel spin, did you have enough speed for each gear?
Testers please don't post results for any posted transmissions till after the tuning deadline passes thank you.
Tune posting
To reduce the headache of tuning the transmission all tunes need to be posted as follows.
Initial Final Gear (IFG)
Top Speed (TS) km/h & mph Google speed converter when switching to km/h round to nearest 10 km/h when switching to MPH round to nearest 5 MPH
Gears
1

Results posting I ask that you post your results for the tuners in the same order as the list for tuners this reduces the chance I will switch up a time.

Looking at the results MrGrado had the best set up with a 2/1 finish on the podiums. I will be studying his transmission closely 
I think with the limited laps we had what we see is the build of the transmission can be worth more than 0.500 seconds on a short high speed track like Grand Valley east, it would be interesting to run testing on longer and or more technical tracks. To see how much a well built transmission can help you there. 
Last time I try that, I'm too lazy for that frustration.
