Junk

Absolutely zero real time or anywhere near close data. I have now made 18 poles and every one of them has been different. Nothing near realistic I have tried every single option available and setting tells me my car has 1100 foot pounds of torque with 40 hp probably the biggest waste of my money I’ve ever spent.

Response from developer

In the settings you shared, the gear fields already include the 4.10 final drive: 13.77, 8.18, 5.47, 4.11 and 2.79. The app multiplies each gear by the final drive you enter, so it treats 1st gear as about 56:1 instead of about 13.7:1, and that throws off the torque figures. The gear fields need the transmission’s own ratios so the final drive is applied only once. For a 1994 Mustang GT with the T-5, enter 3.35, 1.99, 1.33, 1.00 and 0.68, with 4.10 as the final drive.

This is a game changer

This is the only app I’ve even found that can actually calculate your cars horsepower and not need other hardware, pretty cool! Seems to be pretty accurate and stable. Overall I’m very happy with it!
