Tommy Kaira ZZII '00 Tune

[teknic93]

Tuning Track: Nurburgring Nordschleife

All upgrades, including structural rigidity, weight reduction and spoiler have been purchased.The car was tuned with Racing Softs. The car has very minimal understeer at high speed, which can be corrected by shifting a greater balance of torque to the rear wheels. The car will lose a little bit off the launch and acceleration if the balance is changed, however.

Transmission:
Default Settings, adjusted top speed to 370km/h. I was only tuning the suspension, so I left this alone.

I know quite a few use this car online, so can anyone help me with the tune?

What do you need help with?

Any ideas as to how to set the LSD? This setup still has a bit of understeer that I haven't been able to figure out how to eliminate without losing the 60/40 split.

Toe +0.15/-0.20

That toe leads to some serious turn-in issues. Not too sure on the LSD though.

I did try it, and it didn't feel like an improvement. Thanks though.

Bump.

I've found that often things that don't "feel" like an improvement sometimes mean the cars are smoother and more predictable (aka faster), and less twitchy (fast but not consistent). Praiano's Tommy tune in the recent 600PP Tuner Shootout for the Indy Road Course and Oval, was balls to the wall and I wouldn't dismiss it so easily without running a few laps and comparing times. Take advantage of his entire online version of the tune if that's what you're running, or his excellent offline, shootout tune.

It may also be that you need to adjust your driving style to suit this car, with a slightly more measured and precise entry to corners, to set up for earlier, faster exits. Not every car can be thrashed around like an Italia or a GT500 and this may be one of those cars that demands precision, as opposed to brute force to get good, consistent lap times.

I actually did add Praiano to psn and drove his car. It's not bad, but as I said, it doesn't feel like an improvement. My lap times were 4s faster on a lap of the Nurburgring with my tune. That's probably only because my tune was made to suit my driving style, so it's easier for me to drive, though.

I'm really looking for some feedback on my tune, so if anyone has a few minutes and wants to play around with the ZZII, I'd appreciate it.
