Your time slips become tuning intelligence.

60ft is 0.04s slower than your best at this DA range. Your last 3 runs show a tire spin pattern above 1,800ft DA. Drop 2 PSI in the rears or add a tenth to the delay box. MPH is strong, the car has the power. You're leaving time on the tree and the 60ft.

Log Every Pass

Enter your time slip data after each run. NineSlip builds a profile of your car across every track, weather condition, and setup change.

Weather-Aware Tuning

DA, humidity, barometric pressure, temperature. NineSlip correlates your best runs with conditions and tells you when to lean on it or back off.

AI Pattern Recognition

The AI spots trends you can't see on paper. Your 60ft drops when DA climbs above 2,000? It knows. Your trap speed improves with 15% humidity? It remembers.

Track-by-Track History

Every strip runs different. NineSlip keeps separate profiles per track so you know exactly what worked last time you were at Valdosta, Atlanta, or your local eighth-mile.
