Welcome to the technical support page for Skier to Skier. This page is where we will post the latest information on how to setup and use your speed control system.What's new for 2005 PerfectPass 6.5N software How
to Install Magnets Hmmm...... Click here for some picture of how other folks do it. We do not specifically endorse any method of installation. The key is for you to determine what is safe. Depth of magnets depends on many factors (type of timing system, water density, boat ignition system, etc.). We recommend that you follow the directions of the manufacturer of your timing systems. As a rule of thumb -- the closer to the surface -- the more accurate the times will be. The further from the surface, the less chance a skier or boat will come into contact with the magnets. Well, now the slalom switch is now everyday. How can we really use it to our advantage? Why not try different KX and PX settings. Currently, many if not all tournaments are letting the skier pick both the KX and Switch (PX) values. Basically all the PX does is set the percentage value of additional RPM added when the skier is in the lean. Let's say you set the PX at 15 and you weigh 150 pounds. You would get 15% of your skier weight added when you lean -- thus an additional 22.5 RPM. That little boost in rpm sets the skier wider into the turn. If the PX was 20 it would be 30 additional RPM for a skier value of 150. Here are some combinations that we have gotten feedback on as well liked. We have noted that generally skiers who choose the higher KX value like a lower PX value and skiers who like the lower KX value like a higher PX value. These numbers are examples with 2002 Mastercraft LTR Slots or Nautique GT-40s. This adjustment is very subjective. KX Standard and PX of 15 -- For many, this is becoming the standard setting. KX Low and PX 20 - 25 -- Low KX and higher than normal PX. This setting makes the lean pretty soft yet gives a lot of whip like action that tends the set the skier wide. However, boat really releases skier at the ball. Thus, you must be able to hold outward direction to the end of the rope to initiate tight line turn. Boat feels very soft yet lively. Complete freedom at the ball. Lot of throttle behind the boat. Many skiers like this setting skiing in windy conditions. KX High PX 5 or 10 -- High KX with a low PC switch value. Boat feels very firm with a slight release at the ball. Some say it seems to make the pre-turn very predictable. However, must have hips thru the turn as there is less forgiveness as you link back up.
PerfectPass Slalom Skiing KX Values: KX values change how rapidly the PerfectPass moves the throttle. The result is a firmer or softer pull. If the KX values are too low, the rpm's will swing more and the pull will feel soft and easy but the boat will run with the skier into the pre-turn. If the KX values are too high, the skier will feel completely free from the boat in the pre-turn but will feel no give in the pull off the ball. The key is to find a compromise. You have three choices: KX low, KX normal, KX high Why Skier Value must be Close to Skier Weight Every once in a while, I ski behind a boat and as it goes thru the gates -- I get either nothing or the ride of my life. When we get to the other end, I ask "what is the skier value?' and am told something ridiculous like 25 or 450. Both the gate up feature and the slalom switch are based on a percentage of the skier value. Thus, it is critical to get the base line RPM's and the crew weight dialed in so that the skier value is close to the skier's weight. Here is the fix. If you have the crew weight set correctly and the times are off for all skiers. Leave the skier value at the skiers weight and adjust the RPM@ by the same amount that the PerfectPass recommends you change the skier value. That should get the base lines in place. Setting the baselines with no skier only gets you close -- this is the final adjustment for perfection. Crew Weight is also a good guess rather than an exact science. I have noticed the more the weight is to the front of the boat -- the more it seems to affect the times. What I have discovered is that for every 200 pounds of crew weight you add, the PP adds 30 rpm to the baseline RPM behind the scenes. Thus, if you usually get great times but now have added two people more and have the crew weight added up correctly but still getting slow times -- do a little math in the head. If the PerfectPass is suggestion you add 15 to the skier value, just add 100 pounds more crew weight. Same thing goes for the top. Flip it up and make a pass. Note how much the PerfectPass says to add to the skier value. Lets say it says add 45 to the Skier Value now that the top is up. Rather than changing the skier value, add 300 pounds of crew weight for the top (200 pounds of crew weight adds 30 RPM -- thus 300 pounds of crew weight adds 45 rpm.) This will keep the skier value close to the skier weight and give the skier much better gates and a better feel of from the switch. Once you learn how much crew weight your top takes - write it down. Remember too the top is highly affected by the wind. Max's easy chip upgrade procedure. Here is how I have found is the quick way to upgrade a chip. Before your remove your old chip do these things.
Change out the chip for the new chip.
OK, you have read the PerfectPass owners manual and tried the device test on the slalom switch and can not get it to work. Does this sound familiar. Basically, it takes a huge amount of pull to activate the slalom switch in the test mode. I had both feet up on the engine cover and thought I was going to tear the engine cover off. Here are two easier ways. One: Slide the blue shock tube off the switch. Put the PerfectPass in device test mode. (you can find device test in a sub menu under magnet test). Then follow the wire up to the yellow plastic on the slalom switch. The wire terminates at a little micro switch. Press the red knob on the micro switch with a finger nail - screw driver - etc. Switch test should activate. Two: When skiing, the underscore toward the right side of the display turns to an dash mark when the skier leans. PerfectPass Surges at Slow Speeds Occasionally, I get a call about a PerfectPass surging at slow speeds. 99% of the time this is caused by a week throttle return spring. Many people have cured this problem simply by adding an additional throttle return spring to keep the throttle tight. PerfectPass Turns off and on as we ski This problem is almost always caused by a loose wire or low voltage at the PerfectPass. The PerfectPass needs 12 volts to operate. Your voltmeter may say you have 12 volts but there could be a problem with the wiring. Electricity travels thru the wires much like water thru a garden hose. If the hose is kinked -- voltage will drop. If you check the hose at the house -- it has lots of water, but the nozzle has no water. What can cause an electrical kink? Corrosion in a terminal, to many accessories on a wire, a bad contact in a switch, or loose connection under the dash somewhere to just name a few. A quick way to diagnose this problem is:
