The odometer can be set to any number you want, just like a mechanical odometer can! The odometer is constructed using Motorola liquid crystal display drivers, a 4 MHz Motorola MC6805 CPU, and an NCR nonvolatile memory chip. It counts pulses from the speedo gear located in the transmission, and stores the equivalent mileage into the memory about every 10 miles, or when the ignition switch is turned off.

Need to exchange mileage between two digital odometer clusters?

- You need to disassemble the cluster and desolder and swap IC3 from the speedo/odometer module

Need to change mileage numbers or reset to zero after an engine rebuild?
Talk to a speedometer shop, or figure out how the odometer works based on Ford's publicly available patents!

dude, this is some serious sh_t!

I need to figure out how to read the 8-pin chip in my Mark 7. It won't display on the readout but I want to know the mileage. I also need to turn that S back off that came on after I re-soldered the connections.

I'M NOT! :disappoin Zeroing the odometer or proliferating the knowledge on how to do it just makes judging used vehicles even harder.
An engine replacement isn't an execuse either. I put another engine in my Ranger and installed a plaque certifying the original mileage and the mileage on the engine as being different. And just in case anyone thinks that means butkus it's certified by an independent authority! That's right, anybody looking at the vehicle, if I wanted to sell it, can check the veracity by contacting that authority IF they didn't believe the TITLE. Now about titles, yea its against the law to lie or fudge the mileage but in certain cirspoogestances some people will do it anyway. Spreading the knowledge on how to circumvent it OR an Odometer on this board isn't responsible and I think it qualifies as deletable. I have no authority personally but I call on you the poster to TAKE IT OFF THE FORUMS. If you intend to act recalcitrant about it, I call on the moderators to delete it.

If something suffient isn't done in 72 hours I PUBLICLY RENOUNCE MY MEMBERSHIP and request that my account and the information in it be stricken from server or servers. That all photos that I've put in posts be removed as well or if told to I will personally delete them.

By leaving that kind of information up I consider it similar to publishing someones personal and financial information. I don't want to be around that.

Well if you're the responsible moderator..... go ahead and strike it..

I'm more than willing to say goodby I'm not interested in being in the proverbial "den of thieves!" That's my opinion and I stand by it. You want this forum to become that's your prerogative.

I really don't see what the big deal is. Anyone could have figured it out if they had enough time, patience, and know how. If you were dead set on resetting it, you could do it anyways. Its not like switching out the speedo cluster is impossible or anything like that. So should such a big deal be made about someone posting pictures of the bolts on the cluster?

You can tell by looking at the car how well it was cared for. If someone's telling you a car has 20,000 miles, and there's a million cigarette burns, dents and non-matching rims, its prolly a good indication that there lying.

You gotta be willing to look at more then just numbers when you buy a car. Personally, where I live the mileage inst recorded after 10 years of age on the title, or through the dmv.

Well things get a little trickier when someone goes swapping parts and shaving miles off a car. According to the National Highway Traffic Safety Administration as many as one in four used cars arriving on the market each year have had their odometers rolled back. Yeah pedal pads should last 50,000 miles for example, but every time I go to the junkyard and find a Ranger with a compatible heater blower control switch , I grab it! Try to buy one for a 92 at a dealership? You can't. How many T-birds/Cougars have you seen at the junkyard with the pedal pads missing? Bet you've never looked! I've bought cars that looked in very good shape with reasonable miles 4-5 years old with 52,000 miles on the clock. Drive them another 48,000 miles or so and the motor or transmission goes bad. At that point, you know they had more miles on them than advertised!

Maybe I'm being too skiddish or stupid

but it seems to me if you want to be taken seriously about having a classic car or caring about a class of cars because you like them and you think their worthy historically you don't publish how-to articles on zeroing out electronic odometers. After someone has went to the trouble, and it's not that easy to find out how they work and hints on how to circumvent something the manufacturer intended to be secure from the general public; Well it casts a very big shadow on the membership. Yeah, I buy another fox car I'll be asking them if they belong to Cool Cats or have they ever heard of yah. Yeah, I'll be staying away from those cars. :disappoin

Yes JP in your own words you are being stupid. Im installing a 140mph speedo in my TC, its replacing the oem 85mph speedo with 152,000 miles on it. The new one has 1 mile on it.

Yes, people do rollback speedos. I have a nice collection of low mileage speedos for various cars that I buy and sell on ebay. I make a tidy profit and what they do with them is thier business.

The thing is, with our generation of cars, we cant turn em around and sell them like you can a late 90's car. Most of these cars are in their final destination. If the milage is rolled back at this point, who cares? My other car has 182K on it, speedo reads 144K. The car isnt going anywhere, so what does it matter?

If you buy a car based on milage, you have more to worry about. By 60K, my other bird was in 2 nasty accidents, and the only reason it wasnt totaled is because it was only a few years old. Milage doesnt tell you that, and your vehicle components dont fail based on milage. Milage is only good for calculating value based on KBB or other idiotic methods of vehicle value. Look at some of these new cars, 2002 and newer, being completely ragged out with less than 100K, and you look at other cars with 200K looking better than many newer cars.

I agree with Shawn's statements 110%...
I've seen some new cars that were pure shiznit with 20 miles on them, mileage doesn't really mean jack.
Especially considering that most states in the us have a clause on the title "mileage in excess of mechanical limits". Missouri does, for example.
And the last thing, if I buy a 19 year old -box Fox, the LAST thing I'm worried about is whether it's got 20,000, or 200,000 miles, I'm more worried about the obvious mechanicals so I can drive the POS home w/o killing myslef or anybody else. No one here probably buys a worn out, clapped out Tbird or Cougar with the intentions of sinking 3-5 grand in it, to resell to some dumbass to make a profit, and rip someone off...I know if i spent that kind of dough on mine, it will never be sold, regardless of how many miles.
In fact, i think odometers should be banned anyway...miles don't make a car more or less reliable, it's how well they were maintained that concerns me most of all. Brake lines don't rust out cause the vehicle has been around the worl 14 times, they rust cause the SOB that owned it before you or I did failed to wash it after driving on salty-assed winter roads.
Not to be a hard-ass, but basing vehicle reliability on mileage alone is akin to looking up one's ass to determine what one's teeth look like. :hick:
sorry if I've offended anyone, and FWIW, I have 2 chevies here with less than 50 K on either, that have had more than their fair share of non-mileage related probs. 1 Alternator rebuild, 1 transfer case rebuild, heater blower motor (2 times, same car)
several batteries apiece, 1 idler arm.

Funny, mileage doesn't seem as important to me now....
Also, my truck still runs and runs good on the original 5.0 with close to 300,000...so...whatever man :flame:

This isn't about whether or not a car runs good with x amount of miles, it's about making available the information necessary for some unscrupulous individuals to commit odometer fraud. I don't think anyone here would go to such trouble, nor has that evil streak in them but nonetheless it is posted on a public forum. I think that's the point JP is trying to make.

However, Shawn is also right too. By this age, the mileage has a lot less bearing on a car's value. It's an old car no matter how you look at it. I guess the only solution I can see so we don't have this moral dilemma anymore is for anyone wanting this information to email Joe (bondocougar) and have him send them the information privately, that is, if we really feel we're violating a lot of laws here. This would mean a lot of extra work for Joe, but if he feels that the information he posted would be better kept private then I guess that's the only solution. I'm all for learning new things about these car's and NO ONE in recent memory has made such momentous breakthroughs as Joe has. He's the person we have to thank for the 85+ MPH mod. I didn't see anyone getting up in arms about that because 'we shouldn't be driving faster than 85 anyway'. But I dunno... just figured I would throw my 2 cents in.

I don't think this is any reason for anyone to leave the forums at all. If you don't want to be associated with the exchange of this kind of information, delete your posts in this thread and everything. It's not as if the feds will come and bust down all our doors and such. I also don't think Joe should be condemned for trying to explore places of these cars that NO ONE, to my knowledge, has been brave enough to tackle, either. Most of us accepted the fact a few years ago that the base/digital speedos had 'no user serviceable parts inside' and if you wanted to read faster than 85 mph, you simply switched to a Sport/buttstuffog/140 ($$$) speedo.

Well then, if you're concerned about personal information then you shouldn't have made your screen name your real name, wouldn't you say?

Why are you dragging my website into this? I don't have that info posted on the site (yet). This is a message board...two totally different things.

Let's face facts, Jonathan...these cars are valuable to us here on the board, and us alone. Nobody else cares enough to send us their very best. There are no new replacement speedometers for these cars. There are speedo repair shops but so far I haven't spoken with anyone that's used their services. That leaves the reverse engineering for these cars up to the adventurous few in our community that wish to dive right in. Without people like Joe (bondocougar) we wouldn't have some very valuable information about how the electronics in our clusters work.

I bought an engine 10 years ago. It had 42,841 miles on the engine, according to the donor car. My stock digital speedo was at roughly 75,000 miles when the engine was installed. Then I installed an buttstuffog cluster with a NOS FMS 140mph speedo. Was like that for a few years. And now I have an Auto Meter speedo with digital odometer. All with the same "new" engine. How many miles are on my car? I don't know. On the engine? I don't frickin' know. Auto Meter can calibrate the speedo for about $100; I'm sure speedo shops would be about the same, if they'd even work on it. Suuuurrrree would be nice if I could calibrate this horseshiznit myself and save some cash.

And now you understand the need to do this.

If someone wants to reset or modify the odometer for whatever reason, it's that person's reponsibility all the way. I can't control what you do with your car, as much as you can't control what I do with mine. Besides, there are plenty of disclaimers on this board AND on my site which are legal and binding. And I believe anyone with a third-grade edumacation should know by now that messing with an odometer may be risky in their state. It is up to each person to research that. Not me. Not you.

As one of the "responsible moderators" for the board, I can speak for the others...the info is staying. Although in the interest of fairness I think it should be put into a file that can be e-mailed and not publicly traded here.

As a "responsible moderator" I think the info should stay right here. First off, very few, if any, members of this board have the resources necessary to even do this "modification". I consider myself extremely proficient in electronics, and I, myself, would not be able to "toggle 6 TTL lines using either your PC or some other programmable device, IC3 must be removed and reprogrammed with the decimal values 57344 across the 16 memory locations." I would certainly be capable of swapping IC's, but this would be used for the exact opposite of what Jonathan Phillips is complaining about anyway - I would swap MY IC into a replacement speedo. Of course, my car has low mileage anyway.

In fact, I did just that, in spirit. My car had 47,000 miles on it when I bought it, but it had the base cluster. I swapped in a TC cluster, but the 200 km/hr speedo had almost 300,000 km showing on it. Naturally I was not about to have a speedo showing 250k more than was actually on the car, so I took the speedo apart and set the odometer to show EXACTLY the mileage on the car at the time of the swap. I will never sell this car, so I could have put any mileage I wanted on that odo, but I chose to put the correct mileage.

This exact scenario would apply to digital clusters as well. Suppose I wanted a full digital instead of base or buttstuffogue, but the only full digital cluster I could find was an eBay one with 250k miles on it? Should I not be able to swap my own IC3 chip over to get the correct mileage showing?

And as for all 0's, what if I were to decide to start marketing "reman" digital clusters, with the W2 mod (which, BTW, we can also thank Bondocougar for) and new bulbs and stuff? Of course this would require charging a "core" charge so people would send me their old clusters to be "reman'd". What if those clusters showed up with 400k miles on 'em? Imagine trying to sell a reman speedo with 400k showing on it!

Hell, if Ford were to even still offer speedos for these cars they'd come zero'd out. Yes, the "S" light in the speedo would be lit, but thanks to Bondocougar we also know how to do that. Do you think somebody restoring a '68 Shelby 500 convertible is going to insist that the NOS speedo head he found be rolled ahead to reflect the mileage on the car? Why would an '87 Sport be any different?

It all boils down to this: It is up to the individual to decide how they wish to use the information provided on this site. If people want to roll their mileage back they'll do it either by using the method shown here or by replacing the cluster altogether. We are here to share information about these cars, not to baby sit the owners (and sellers and buyers of them). You will note that the info shown here only says how to zero the odometer and/or change the mileage to reflect your own by using your own IC3 chip. If you come across a zero-mile, 20+ year old car, you should be able to tell if it's legit just by looking at it. Nobody is going to go through the trouble of rolling an odometer back to make a 150k mile $1500 car into a 50k $1700 one. If you feel so strongly against something you read on the internet that you threaten to leave the place you read it, you may as well unplug your network cable now and use your computer for solitaire, 'cuz otherwise you're in for a bumpy computer experience. The internet is a nasty place, and it's up to the individual users to protect themselves.

Wow, your true colors are showing. I guess in your mind "all Foxs are boxes." Yea if you would ever sell your car who here would buy it given your beliefs? What could you say now about a fox that you own that you wanted to sell that would be believed? If your willing to implicitly lie and that's what your defending, then how can anyone believe anything you say. I guess its ok to steal from the ignorant. Let me tell you something just because your ignorant doesn't mean your stupid. Even if i'm stupid it doesn't justify defrauding me either. By the way there are way more people that believe that mileage effects the value of a car otherwise why would it even be in so many advertisp00gets and books? The mindset carries even to vehicles not in the 2007 NADA book! It's the difference between a "peach" and the pit to many people.

If you hate Fox cars so much, why don't you buy a car you really like and go to some other forum to post. I guess I'll have to sell the car I like and post somewhere where, truth is valued a little more or is inforced by its members.
