Redneck Perfect Pass

The humming bird works like a champ! Easy to install and has never failed me. It is a little slow but nothing to bad to wakeboard with.

Well I've got the thing now so it's going on whatever, but I'd be curious to know what morfoot thought of the pull.

That's what I've got. Mine has been removed from a car. I don't think it's manufactured any more.

I was going to try it just on revs for now. Was talking to someone at the weekend who had PP wakeboard pro on his boat and said he always ran it in RPM mode because the speed mode never worked right - I spent a season riding behind the boat and was never aware of any issues with holding speed.

The pulse generator is the way I'll go if it doesn't work. I was wondering this morning if anyone has written a pulse generating ap for the iphone? Tunes, comms and speed control in one unit - now that's effecient.

Doc, may need a bit of info on this as i have come by a ccs100 cruise unit and am thinking of using it on the boat if you are still happy with it. If not what was the problem?

From another thread...

If that is indeed hall effect does it produce AC or DC voltage. I have one hooked up in the shop and cannot get a reading either way,sorry for being less than smart on this issue. Share some brain cells with the old man..................Billy

Billy, I believe the cruise control uses a hall effect switch where it does not produce voltage or current. It is a pulsing contact.

Think of it like a wall switch for your lights at home. If you turn that switch on and off as fast as you can with a meter across it, will you generate electricity? Nope. However, if you apply 120V and a light bulb to the circuit, you can now turn the light bulb on and off. If you turn it on and off really slow, you have darkness and light. If you turn it off and on really fast, you'd have something that looks like a continuous dim light. If you turn it on and off super duper fast, you'd have a bright light.

Well, that is how your cruise control module reads the speed from the hall effect switch and the magnets on your coupling. The cruise control module supplies (sources) power to the circuit and reads the frequency of the pulsing contact to figure speed. The module then modulates the throttle actuator to make the frequency equal to the frequency it was reading when you pressed your 'cruise' button.

If you want to read anything from the hall effect switch, you need to use your digital volt meter and measure the frequency. It should go up and down as you rev the mighty 331.

Has anybody done this to their boat, and used it for wakeboarding yet? I can pull people at a steady speed, but none of my friends can do it for me. I would love to do this for under $100 but not gonna pay $1000 for perfect pass.

I wanna hear from you before I get started on this. I wakeboard at a small lake, and need to know how it does on the turns pulling a wakeboarder.

Thanks

Doc, I never had any doubts what so ever that you wouldn't get it going! Fantastic!

Gary,
I found some more info on the S9020 Nordskog GPS unit. It can put out 8000 pulses per mile or 16000 pulses per mile. I have a data sheet if you want to look at it.

If the PPM needed is not 8K or 16K, they have a pulse converter module for about $100, model S9000. It will translate to almost any PPM for any specific application. I have a data sheet on this as well.

I'm pretty sold on using the S9020 to drive an analog Stewart Warner speedo. I'm waiting to find a good, matching SW gauge on Ebay to keep the costs within reason.

Tim, give me a call anytime today......
I will leave early for a trip to town about 4;30 cental time 1-318-386-2825.....Billy

Eric, I can't even buy a brick for $100!

Billy, Where did you buy the kit? The ones I see for around $100 are the vacuum operated ones. I think the electric version would work better since my cam doesn't make alot of vacuum.

Thanks!

Dr-

I will be installing mine this weekend. Any best time to call you??


Thanks

Tim

So it works fine? How does it do around 20 mph? That's the hardest speed to hold...boarding speed. Skiing is not problem.

Where did you mount the actuator?

Is the actuator strong enough to move the pedal up and down? It kind of looks like you installed a "slip link" on the morse cable but I can't tell for sure.

Looks like I'll have one soon! Sweet!

Thanks for the pics!

Tim, thank you bunches for posting the pics for this Old Man.As you can see there is not much to see,the switch on the dash, and the actuator cable sitting beside the Teleflex throttle cable.
The return spring is not needed but was installed for safety reasons.
The speed sensor is mounted in a hidden area,close to the coupler.The two magnets, epoxied to the flanges and the glass tape , just for security of the magnets.
The actuator is mounted with the cable going to the floor and then following the throttle cable. Wiring for the control unit then passes along the starboard stringer to terminate at the swich mounted on the dash.
Works better than I would have dreamed, and still have coins for a couple of gallons of fuel.............
The "keep it originals " will scoff but..........Boat dr

Matt, 3/4 of the hours spent on the install were used on the "linkage and return".I could spend an hour trying to describe the pain I went thru to "fail proof" the linkage and the return springs.
Simple is always my mode but this does not translate to ease of fabrication.
If you would like more info or just want to talk "redneck" my phone is always close and love to talk to fellow CCFans.......Billy
