I have many carsets for NR1, including Winston Cup, Bucsh, and Craftsman Trucks and would like to make them more realisticly different. The only way I have figured I can do this is to edit the Drivers2.txt files for each carset. I need to know if anyone knows how much of a difference a power rating of 800-900 would be from say 100-200. If I can figure this out and incorporate this to the traction, drag, and aggression settings, I can make it more realistic. Thanks in advance, Gary

Sim = IndyCar Racing II Track = Michigan AI Settings = 100% Strength BLAP=30166 RELS=100 With all numbers set to 500 for min and 501 for max the AI Lap Times were equal to 234.045 MPH. This is the "baseline" setup. This means that with these settings the AI will run the EXACT lap speed of the value in BLAP. Every time, 100% of the time. Even if I set ALL drivers the same then they will ALL run EXACTLY what is in BLAP. This is how the numbers effected the lap times (all settings = 500/501 unless noted): Setting Value Lap Speed --------------------------------------------------- Aggression 998/999 234.045 MPH Traction 998/999 248.464 MPH Drag 998/999 221.195 MPH Traction & Drag 998/999 234.045 MPH Power 998/999 248.464 MPH Traction & Power 998/999 264.804 MPH Traction, Drag & Power 998/999 248.464 MPH Look carefully at the overall lap speeds. Some are equal with huge changes in the numbers for each setting when combining changes. This is because the numbers make up a formula based on these settings along with AI Strength (in the options menu) and the BLAP and RELS numbers in the track.txt file as well as the values in the .LP files in each directory. A summary: Aggression: Higher = more tendency to block and hog line Lower = more tendency to give up line and not block Either way it has absolutely no effect on the lap times Power: Higher = better acceleration out of corners and higher top speed Lower = poorer acceleration and not as high of a top speed Traction: Higher = better cornering ability and more grip for late braking Lower = slow in the corners and WAY early on the brakes (wimps) Drag: Higher = lower top speed and poorer acceleration Lower = higher top speed and better acceleration Each of the above is based on an adjustment of just that setting. When changed together it is combining a formula that has many variables that will make the same lap times. However, even with the same lap times, the AI will still drive differently depending on what has changed and by how much. The best thing to do is start from a baseline of 500/501 and use the BLAP and RELS numbers to get the AI to turn laps that you can run as well. Then, based on your driving, either add or subtract the settings to tune the AI to your abilities, such as a lower straight speed, but better in the corners based on the charts above. Experimentation is the best you can do. As you improve, make the adjustments to the AI as well. It will make you a better racer when you are going 100% full out and you are stuck 0.4s behind the car just in front of you lap after lap. All you can do is pray for traffic and hope for the best. It is possible to get most of the tracks equal with just one DRIVERS2.TXT file, but it is almost impossible to get them all equal. That is due to the way the .LP files come into the equation. Sometimes they just go too slow in one corner, but are ok for the remainder of the track. That is ok, but then when you turn them up for that one slow corner they will smoke you over the rest of the track. Sometimes it is best to leave them slow in a few corners so you can get the overall laps better adjusted.
