I just have a spreadsheet with all of my cars in it. I use a timing system on my laptop. I pick out a car, and I try to beat its fastest 2 minute run. Some nights, I try running two or three minutes on each lane and taking total laps, just like I would be doing in a real race. I do allow myself a mulligan on one lane if I have a real problem, as I have to self marshal. Other times, I have the spreadsheet sort the cars by speed, and I take a car and try to tune it to beat a car that was ahead of it on the spreadsheet. Then they end up switching places. Once, I had a whole day to kill, so I took four cars that I was tuning to make a matched set. I set up four identical controllers, and put one car in each lane. Then I ran three minute runs with each car. Then, I moved each car ahead a lane, just like racers rotating in a real race. I ended up driving all four cars in each lane and recording the results. (Four cars times four lanes equals 16 three minute runs!) After looking at which cars did best in which lanes, I tuned them a little bit and re ran the whole test. This helped me set up the four cars for IROC racing so that the car were placed in lanes that gave them almost identical times. With the faster cars in the slower lanes, the IROC race stayed close for all four segments!
Other times, I just go through the spreadsheet over the course of a few days, trying to make a faster run with each car. I usually start with the slowest ones, and progress to the fastest. I just keep track of where I left off, and make a two or three minute run with each car in a specific lane. I have columns in the spreadsheet for the best two, three and five minute runs in all four lanes, the fastest lap in each lane, the fastest overall lap, and the fastest four lane "Race" at two and three and five minutes per lane. (Sometimes our club goes two, sometimes three, sometimes five) Of course, any time I work on a car, or modify one to a faster class, I run it and watch the spread sheet sort it into its new place. I also try to run the cars in all four lanes, lest I have one really rubbered in lane and three greasy ones! When I had to move my track, I was finishing up making a batch of two minute runs with every car in red. Next, I was going to run them all in yellow. I always made sure I had done an equal number of two, three or five minute runs with all of the cars in all four lanes before going back to my favorite lane again.
One funny thing I learned was that my old track gave a lot of cars their quickest lap in the two middle lanes (This is to be expected) fairly evenly split between blue and white, but certain classes and types of cars seemed to like one lane over the other. About a dozen of my cars had their quickest lap in red! (Gutter), but no car ran the fastest lap in yellow. Several cars, though had their fastest three and five minutes in yellow! No car had a fastest five minute run in Red. My track had a bridge, so all of the lanes were equal length, but the two gutters had very different challenges. There was one R1 turn in each direction. The esses and the increasing/ decreasing turns made the challenges in the two gutters very different. Red was tricky to drive, but if you were perfect, you could get a killer lap out of it. Yellow was a bit slower, but more mellow and repeatable from lap to lap. Very few people would make three minutes in red without making a few mistakes.
With my new layout, I have to start over. I think I will just record all of the runs at three minutes instead of the three different "race" lengths. That will make the spreadsheet a lot easier to manage. The bad thing is I am going to make the new track bi directional. I will have to keep a second section in the spreadsheet for reverse direction.
Of all of the formats, one of my favorites is taking a car and tweaking it to beat the time of a similar car that is ahead of it on the spreadsheet. I make sure to spread the love and work on all of my cars over time though. I usually keep track of which cars haven't been run lately. For me, tuning and tweaking is a big part of the game. Since I do race with other people, it is a good idea to keep improving my cars.
