Zemco Compucruise 44 New In Box...
 

I was looking for a Compucruise trip computer for my 1986 Tercel wagon, and bought out the stash of a Zemco dealer from the 80s. If you have a carbureted car, and want a trip computer for instant feedback on fuel consumption, here you go. Features include:

Clock

Elapsed Time

Stopwatch

Trip Time

ETA

Alarm (wakeup or reminder)

Distance Traveled (miles or KM)

Distance Till Arrival (miles or KM)

Distance Till Empty (miles or KM)

Fuel Used Since Fillup (gallons or liters)

Fuel Used on Trip (gallons or liters)

Fuel to Arrival (gallons or liters)

Fuel to Empty (gallons or liters)

Current Vehicle Speed (MPH or KPH)

Average Vehicle Speed for Trip (mph or KPH)

Current Fuel Consumption (GPH or LPH)

Average Fuel Consumption for Trip (GPH or LPH)

Current Fuel Efficiency (MPG or L/100 KM)

Average Fuel Efficiency for Trip (MPG or L/100 KM)

Inside Temperature (F or C)

Outside Temperature or Coolant Temperature (F or C)

Battery Voltage (volts)

Cruise Control (digitally input speed)

Cruise Control (engage at current speed)

Cruise Control (resume)

Night Time Display Dimmer

The price is $150 plus shipping, and the kit is brand new in the box from the 80's. The kit is made for a carbureted RWD car. If you have a FWD car and need the extra sensor kit, I'll include one for an additional $5. I don't have any of the fuel injection interfaces, but from what I've read, they're not hard to build. This was one of the best aftermarket trip computers ever built, and they're getting about impossible to find brand new in the box.

I have one of the older versions before they had cruise. I have replaced a few things over the years and still have it installed on a rabbit diesel to this day. I found that a modern cam/crank position sensor works well to pickup the six bolts that hold on my front drive shaft. The recirculating ball has been replaced with a .12 gram competition plastic BB. And the light source in the flow meter has been replaced with a white LED. Those are the only things that I have replaced in almost 30 years.

I'm going to install mine with a speed pulse generator in a two-piece speedometer cable. I'm also using a vacuum servo and the relays from an A-R-A cruise that was made specifically for my car. That setup will allow me to mount the servo under the dash to work directly on an arm bolted to the top of the accelerator pedal. The only part mounted under the hood will be the two relays and their bracket. I need all the room I can free up to mount the tank for my Waag-Injection kit.

Zempco Compucuise
 

Hello, will this unit work with 1989 Honda Accord LX1 2.0 liter fuel injected engine? Please advise, thank you...James

Not without an interface box for the fuel injection, and they're impossible to find. I know a guy who has the schematic if you want to build the interface.

Great, can you send me the info so I may contact this guy with the schematic, thank you...James

When I get the schematic from the guy you know I will then be able to build the interface, thank you...James

I like your Zemco. Questions
 

Dear,

It is probable that you have what I want. A trip computer for carburated engines. However, I need it for a diesel engine, year 1995, non electronic.

Then, I need the extra sensor.

However, before purchasing it, I need more info, as to ensure it will serve my purposes.

For instance: will the fuel flow sensor work? Are are they designed to deal with fuel flow sensing?

Thank you very much,

Old Beaver

As described, this is designed for a carbureted engine, and diesels don't use carburetors. Any adaptation work that this would require would be at your own risk. I've listed everything I know about this unit.

Zemco Trip Computer
 

Dear,

I understood that you said for a front wheel drive car the Zemco will need an extra sensor.

What I need to know is how the Zemco 44 TC connects to a carburated engine. If you can scan the connections diagram, I will know if I take the risk or not.

At last, "a carburated engine" means a non-injected engine, that is, the fuel flow sensors are not attached to injectors. That is exactly what I need: to sense the fuel flow somewhere else. It probably uses mechanic flow sensor, and that is what I need.

If you do not want to send me more info about the Zemco 44, then please tell me about the fuel flow sensors it uses, and where can I get them. Just give me the brand and model. Of course a picture will be a useful complement.

Thank you in advance for sharing that info with me.

Hi there just wondering if you still have the compucruise in you possesion
Glenn

Zemco
 

Do you still have the zemco for sale
Regards
Bruce

Sorry, they've all been sold.

Could I have that info also because I have a zt2 by zemco I would like to hook up to my 92 lebaron or 1996 dodge ram

thank

phw

could I have that info for the schematic PLEASE

Zemco EFI interface
 

Greetings clbolt;
I am looking for the EFI interface schematic (have been for years). Do you still have access to the schematic?
Thanks in advance,
Flynlow

I have a copy, but when I built it it did not seem to work so if you can figure it out, please tell me.

Email me at racprosp@cox.net and I will gladly send you a copy.

Rich

I found how to upload pictures so here it is.

Rich

sweet, I was bugging cbolt for a copy. That is wild.

'course I'd be doing all that in software these days on a $3 chip.

A friend has redrawn that drawing and corrected a couple of the mistakes...

I am waiting premission to post his updated drawing.

Note there ARE mistakes in the drawing...

He is also going to breadboard a test model and see it it can be made to work.

More when it is done.

On a personal note with the MPGunio doing a better job on FI injected cars, these old units are really better used on cars with carbs, so if the MPGonio works as I beleive it will, I maybe offering my four Zemco Units to those with a greater need for them.

As I can not think of any way of making a MPGunio work on aolder car, even with a add on VSS driver, I can think no flow meter will give the pulase wirth that a injector will, and if I understand the current set up thus the MPGunio will not read MPG with a flow meter count..??

Rich

It would be trivial (for a programmer) to reprogram a mpguino to read fuel flow sensor pulses and assign each one a fixed amount of fuel for display purposes. Heck even a bicycle computer can be calibrated to read a fuel sensor and give a meaningful result. Diesel John has been looking at the sensor end of it closely:
http://ecomodder.com/forum/showthrea...gine-1123.html and I haven't come up with anything better.

But I agree that the still functioning zemcos would be best put to service in a carbureted vehicle, at least until something else comes along.

HA I kinda thought so but as I did/do not program it I was thinking outside the chip whereas you are able to think inside the chip/program.

Can you also program/set it up to read off a small coil that is responding to a pair of nagnets on a drive shaft??

Did you see my post about the peak and hold injector adaptor??

And have you considered makeing they with a case??

And have you considered suppling the three buttons on wires so the builder can pit them in other places?

Rich

What about the changes in the diagram ??

thanks

phw

I asked and he said he wants to wait until he can test things on a breadboard before giving it out.

Once proven he will send me a copy.

And either he or I will post it.

Zemco Units
 

Hey racprops, if you (or anyone else) has a Zemco unit that you are willing to part with I am interested. Drop me a note at chazh@bellsouth.net

Thanks

Unsure but interested.
 

I've been looking for a fuel flow monitor.

Are there any of them left? If yes how much to ship to the United kingdom?

Hi there mate, I have one currently coming to the UK this December. Apparently they only can be fit to carb cars but mine is a EFI car. Cheers there.

Zemco Compucruise 44 parts
 

Do have any parts for the model 44?
I need a either a replacement cruise control vacuum servo or the internal vacuum connector for my Compucruise 44. The vacuum connector broke off rendering the unit inoperable. It's installed on my 1980 Mustang. I miss the cruise control.

Thanks.

Re:Zemco Compucruise 44
 

I came across this very old post of yours and was wondering if by any remote chance you still have one to sell to me? If not, perhaps you know where I can look for one?

Funny you should ask, one just popped up on ebay:

ZT1 Driving Computer w Cruise Control 1980 Zemco Brand New Old Stock | eBay

Best of luck.
