Speedometer Calibration

Featured Replies

SO I got a question. Im lookin to buy Reason's aftermarket guages seeing as how his Legacy is totaled.:-\ The issue is that the speedo goes up to 140, where as mine only goes up to 120. Therefore my speedometer would need to be re-calibrated. One Subaru place told me that they didnt have the tools. Another told me that you cant re-calibrate them, even in the newer ones. And auto electric specialist told me that it should just plug in, which I realized later doesnt make any sense since Im not replacing the actual speedometer itself. A friend of mine told me that he got bigger wheels on his '01 Dakota and he just went to the dealer and plugged it in and no problem. So Im trying to figure out who here is actually correct.

Now i played with this. I forgot how it turned out. But the spedo is made up of two parts. There is the spedo head, and the board which it plugs into. The 140mph spedo has a different electrical connection then the 120. When you get the gauges, get the pigtail off the back of the cluster also. It is a two wire plug in the center of the back of the cluster. Just have him snip it.

When you hook it up to your car, you use that pigtail and it should work. Wire it in temporarily by striping the wires, inserting them in your connector and taping them up. you wont hurt anything.

Then i am 90% sure it will work.

Hey thanks alot.

 

I def. dont want to mess anything up, seeing as how my speedometer itself is brand new.

care to share a pic of his gauges? I am curious

 

nipper

Oh ok so your doing exactly what i attmepted to do. Let me know how it works with the pigtail. Otherwise the gauges just plug right in.

the wire that comes out the back of the gauge cluster. Any wire with a connector on it is a pigtail.

The problem is that I need a 140 mph speedo. The owner of this one drove it around with his 120, which I am currently holding in my hand. If I could find a wrecked '96 Legacy with 90,000 miles on the odo. that would work. I dont know why Subaru changed their speedometers in '97.

Ok back to the begining. Didint you get the complete cluster with the 140mph speedo.

 

I thought you did.

 

I told you the only differnce between a 120 and a 140 seems to be the connector in the back of the cluster, and that you should get that too. They look like they use the same VSS sensors and pulses, and all the black magic is done in the cluster.

 

The change was probably done because of either a- insurance issues b- they started governing the engine or both.

No :-\

Let me check in my stock pile of stuff from my 95 car I had a few years ago, If I have a 140 speedo I'll send it to you at cost of shipping.

That would pretty awesome.

I should be able to let you know tomorrow night, as the stuff from those days is still at my parent's house, I'll be up there after work tomorrow.

 

I had those exact same guages in my 95 wagon, up until one of the wires broke off, they are somewhat delicate, so take care when handling them near the area the wires go to the actual guage.

Thanks for the tip. Any idea how many miles you have on odo? My car is gonna look real screwed up on record. Had 80,000 and had the speedo replaced cause it broke, so I started back at 0.

I think it had 140k or in that area, I replaced the whole cluster with one from a 95-96 L because I the brighton with no tach, might be possible to roll it back to get it close to where you would like it. I personally wouldn't worry about it unless somebody buys the car and tries to say you've lied about the car's mileage.

No plans to sell it anytime soon...maybe ever.

Not to worry then, most people don't even think about that kind of stuff when buying a car. A friend of mine got screwed over on a 00 honda prelude and paid way more than he should have because the odometer had been changed, the dealer knew about it but fail to inform him of it. He's currently exploring his options of suing them because of this.

Damn dealers. Subaru sold my bro an Impreza that had been in an accident and was in no condition to be sold.

It's not too uncommon to find flood damage cars on lots either. But some time back there were several cars damaged at a local ford/used lot when we had a pretty decend flood here. At least ten of them showed up at a small lot and they claimed them to have never been in water at all... After a long discusion I pulled up the carpet in a sebring and showed him what I knew, end of dicussion he walked away mad as hell.

 

Anyway, I check where that speedo 'should' have been, but my dad has been moving stuff around in the building. Would have tried more but a car hit some black ice and clipped a power pole knocking out power on the block until after i left. I'll scrunge around some more over the weekend.
