Машин стал ехать бодрее. Выкладываю рекомендации, которые получил от производителя.
The 20 inch rims is irrelevant; if the tires (rubber) is not the original size that came on the vehicle from the factory the speedometer will not be accurate. You’ll enter the new tire size to correct the speedometer. Measure the tire from the ground to the top of the tire while mounted on the vehicle with proper air pressure and enter the measured diameter to the nearest .25 inch and that will correct the speedometer. Do not use what the tire MFG states to be the tire size.
The shift points only affect wide open throttle shifts, recommend going =300 RPM on the 1-2 and the 2-3 shift. Most don't move the 3-4 shift, at wide open throttle at the 3-4 shift you will be traveling at a high rate of speed that most never see. The shift pressure is a yes or no answer and I'd definitely recommend choosing Yes. It helps the transmission clutch packs last longer since they don't slip and the transmission temperature is lower. Choose no to both the tire and gear option unless there has been a change from what came stock. The speed limiter is also your option, if you want to go faster than the stock 98 mph speed limiter move it up, as long as the vehicle is equipped with the speed rated tires you have selected. I hope this helps and we appreciate your interest in Hypertech.
I’ve attached the dyno chart that shows the power gains for both settings.
