[Help] Vehicle restricted to 25mph ------------Cushman Super-Van

Hello all, I have a oppurtunity to purchase a Cushman Super-Van, with 26miles on it for a decently low price. Only issue with the vehicle, is it's somehow restricted to 25mph.

The vehicle I will be purchasing can be seen in this manufacturer pdf attached.

The way they were imported was to have them restricted to 25mph so in some states it could be classified as a low speed vehicle for road use.

We will be using it off-road use, and do not need the speed restriction.

Has anyone here had any experiences with these vehicles? Cushman Corp is not of any help.

Ideas? The one in question is a 4 speed, can shift into any of the speeds, seems electronically restricted, though, is extremely quick off the line (I ran raise the front wheels off the ground with ease!)

Cheers!

I don't know about WI, but here in CA, there are some vehicles that are allowed to be used on roads with speed limits of 25 MPH or less.

Various "city car" genres are included, but since my driveway terminates on a 55 MPH road, I'm screwed.

It seems that with a 1200cc engine that Cushman could easily attain 65 MPH. A little reverse engineering might be in order.

That is part of the issue, the vehicle is limited to 25 MPH or has to pass stricter safety regulations if it is faster than 25MPH.
Cushman is not in the business of producing "off road" vehicles so no help will be coming from that direction.

Just a suggestion, I would be looking at real off road buggies instead. Built for that purpose, faster, probably safer.

Re: [Help] Vehicle restricted to 25mph ------------Cushman Super

Safety is not the issue. I already sell 3 other brands of street legal chinese cars. 1 low speed Electric one that is a Smart Car Knock-Off, 1 that is a 3 wheel electric truck/cars, and 1 that is three wheeled gas trucks and cars. I yah, safety is not the best in them, still better then a cycle.

Reason being, I can get this one for less then $3,000 brand new with 20 some miles on it. When I say off-road, I'm not talking about mudding or going off paved surfaces, I'm talking about off street use, such as parking lots, and other off-street paved roads where 25mph does not cut it.
So I'm no stranger to Chinese Vehicles. Just not then perticular model.

Cheers!

Well, it is fuel injected, so you would probably be looking for a speed signal wire to the engine control computer.

Heres what Ive found thus far.

Their is a fuse labeled governor, and the truck has a carb. I pulled the governor fuse, and it killed the engine, so I think it's in the computer somewhere. I will investigate further.

If it's a carb engine then the fuse is probably wired in with the ignition circuit. Should be easy enough to test out with a voltmeter. It will be unsafe if you get around the governor though.

The PDF you provided says that it is fuel injected.

If it has a carburetor, would not the governor control the speed via a mechanical linkage? One that could possibly be disconnected (for testing purposes, of course)?

It's probably throttle-body injection. 71hp, 2700 lbs, I had an old Datsun with similar specs, I bet it can do 80 if it's geared right, given no headwind and a long enough flat stretch.

As far as safety, it looks to be ca. 1980 suspension and DOT tires, it should handle OK if you don't get too wild. I bet they drive these highway speed in China. The issue is probably crash protection and emissions. Just don't crash at speed.

I'd look for the speed sensor (probably near the tranny output) and unplug it. You'll lose your speedo (if it has one) but I bet it will go then. Use a GPS for speed, it's more accurate anyway ...

Yah, it does have Carb. It's 71hp, but carbed. I drove one of these in Vietnam, as well as rode in many in Vietnam, and they take these suckers through the mountains flooring it on 2 lane roads with thousand feet drop offs inches away with no safety baracade on the side of the road. Just dont hit anything! Though, these things are very agile, and take off like a rocket! On one of the main highways, we were doing about 70mph with 10 of us in one of these (Fit 10, even though seats 8, as it was 1 white guy (me) and 9 vietnamese (wife and her family), and they all weigh 65-85lbs, I weigh 170.....)

I think I have video, I'll post it if I can find it. It does have DOT Tires from Duro, same people that make my dot cycle tires for my 49-250cc scooters.

Some videos.

The video of the busses are in DV, and are 5-6 gigs/file, so I will need to figure out a way to edit out clips.

Can you either post a couple of pictures of the carb, or post a PDF that actually applies to the vehicle in question?

In the pictures above, the bottom three are a Toyota, not a Cushman. I don't know about the one on the top.

Edit:
I should clarify that I meant the vehicle the photos were taken from.

That "Cushman" isn't a Cushman....

It's made in China by First Auto Works.

The speed limiter is a custom US only firmware in the PCM that cuts both fuel and spark.
It IS possible to flash the PCM back to the original outconus (outside continental us) firmware.

Yep, you betcha, I know more about that vehicle than you could possibly imagine......I helped design it for the US market.
»www.vantagevehicle.com/

You can't get the original firmware, the interface is coded in chinese charicature, and it's ILLEGAL in the conus to go over 25mph on or offroad in a vehicle classified as OFF ROAD USE ONLY.

Talk to the HTHSB if you want to change that....it'll cost a few million for them to test everything and say NO.

Yah, I know Cushman doesn't make it, just the importer. Like I said earlier, I'm very usted to dealing with imported Chinese Cars, scooters and electric cars.
I've been to the factory that makes the electric version.

I was starting to think that it was in the PCM, and being so, I'm SOL.

Guess I'll just stick with my electric buggers ^_^

Cheers!
Thanks all for the input!

It IS NOT a Cushman.

They have several engine options, ALL being a Toyota licensed and based 4 cylinder with full bi-directional OBD2 compliance.
They are ALL fuel injected, carbs are not legal in the US on new manufactured VEHICLES displacing 500cc and above.

»www.faw.com/webcontent/index.jsp
Go there, you will find first hand who makes them.

They have Chinese Delphi (GM) electronic control systems on them.
FULL OBD2 compliance, that means full feedback, no distributor, no carb, full 3-way cats....and so on.

If you don't know about them, please save your comments to yourself.

Here is a pic of one of them that I built for Bellagio hotel/casino in Las Vegas as a people mover tram...
It IS NOT complete in this pic so don't get all pissy and stuff.
I built 4 of these for them.
Go there, get a ride from the parking lot to the lobby....you will ride in MY HANDWORK.

I did all the prototype work on these for the tram, the dumptruck, the scissor lift, the convertable scissor-dump, the 4 cu.yd. box hauler....etc etc etc and so on.
I have thousands of pics, this is just a simple one that you guys can figure out....mmmk ?

Re: [Help] Vehicle restricted to 25mph ------------Cushman Super

Appears that someone in similar circumstances as you had one quick and cheap method done. A gear ratio reducer made for the speedo cable ~$60, which doubled the speed to 50 mph.

See: »www.minitrucktalk.com/showthread.php?t=1742

Assuming it is the same set up as the one that you are looking at.

Actually, there are more than one way to skin the cat.

Instead of messing with the PCM, you can just 'modify' the output of the speed sensor -- put a 2 to 1 or 3 to 1 frequency divider in there to double or triple the cutoff speed.

It called a governor, and they are NOT road legal (crash standards etc.)

They are only legal for private property/campuses.

The ONLY Cushmans that have ever been road legal are the meter maid 3 wheelers, because they are considered scooter/motocycles, and do not have to met those standards.

The 4 wheel versions of those even are again not DOT road legal..

Not necessarily, I have a 2001 (last year they made them) Cushman road legal 3 wheeler.... not actually a governor, just the transmission is geared so low it just doesn't go over 35.... well actually 42 but it is very unpleasant at that max RPM.

So unless you want to rebuild the transmission or rear end that's it.

But since max speed on all of Key West is 35 tops no big issue for me.
