My torque lite app works for all that stuff already. However, driving a 5-speed down the interstate, the coolant temp (for example) changes so very little (always in the thermostat opening temp zone), it's useless data. Which means, the cooling system is adequately sized for a 5-speed ... one that's not towing. I'll have to run that app the next time I tow and see if the coolant goes higher.
