General Questions

4wheelers

I have some questions setting shift points, under load condition. Does this controller have the ability to learn duty and shift points under real condition?

1. Does the controller have the ability to learn by repeating the conditions under flight?

2. Is it possible to set the basic perimeters, triggering the shifts at the desired throttle (TPS) and also with the actual speed count (VSS) and have the controller repeat the conditions? In addition using a (MAP) sensor to calculate load condition.
3. It would be like having the controller use snapshot frames to learn from? Wink

4. Has PCS, LLC thought about offering a generic (TPS) with mounting plates? Also a (VSS) tone wheel ring and a mount kit for rear differentials? As an option kit for general applications? Question

Don,

1. Our TCU is fully programmable for desired shift points based on your load condition and speed. This is a 16 point table for each upshift and downshift for each calibration. There is not an easy way to autolearn, learn, or assume what operating conditions exist for the wide range of applications our controller is designed for. Luckily, it is very easy to sit down and tune most applications for specific conditions.
2. The "transmission setup" section of our software includes all the basic parameters for your transmission including TPS parameters, speed input counts and load determination. You can only select one form of load determination which decides how shifting is accomplished (MAP or TPS). However, you can use additional inputs to trim the line pressure & shift points based on any analog voltage. So you can base your shifting on TPS and use MAP as a trim so that your shift schedule is modified at high or low boost levels. Alternatively you can base your shifting on MAP and use TPS to trim your shift schedule.
3. Our unit works on tables of points so you can determine the settings you want from specific conditions and input those points. For conditions in between you will need to interpolate or guess and refine your tune.
4. Yes, we have. We do offer a basic remote mount TPS kit with a plate for carbureted applications. We have not yet addressed the possibility of a generic signal wheel and speed sensor for differentials or wheels as most applications have some sort of speed indication and our unit is compatible with wheel speed, output shaft speed and transfer case output speed.

I'm not sure if I answered your questions as I am a little unclear about what you are asking for. If you still have questions, feel free to ask again.
