Rolling Odometer Mileage Forward
I am swapping out my s4 cluster with an s5 cluster, both NA clusters. I already am aware of the wiring diffences and that is not a problem.
What I would like to do is roll up the mileage on the s5 cluster (has 90k miles on it)to match what the car currently has (230k miles!) I want to avoid any possible problems in the future with odometer fraud.
Can this be done safely without risking any damage to the odometer?
I can not seem to find a thread about rolling forward, only rolling back.
thanks!

There had better not be a thread about rolling them back. 
As far as rolling forward, connect a drill to your speedometer cable. 1025 Revolutions is one mile...
So if your drill turns at 3600 RPM, you'll get about 3.5 miles per minute and the speedometer will show 210 MPH. You'll probably heat up the speedometer cable and bushings in the speedometer at that rate, so I'd stick to about half that speed and take breaks after a while.
Even at 3600 RPM, it'll take you 27 days of non-stop running to advance your 140K miles.
I think I did all my math correctly, someone correct me if I'm wrong.

I swapped my S5 turbo cluster with a S5 NA cluster and just swapped the turbo speedo into the S5 NA cluster... I'm not sure if they're the same for S4 and S5 though, but I think they are... That would be the easy way to do it.
with my corolla I ended up just taking the speedo apart and manually forcing it forward... it worked and has been working fine ever since. 230k and still going

I just found the thread regarding modifying odometers... Looks like they're simple enough to dismantle and **** with in these cars. Not worth the drill time... Nor is it worth deleting, because a retarded monkey can figure out how to change these odometers...
I too, wrongly thought that the odometers had something that'd drop in between the digit dials to space them out if the odometers were tampered with.

Keep in mind that I do not endorse odometer fraud and any vehicles found for sale with undisclosed odometer changes will be reported to the moderators in the for sale section.

I rolled mine back to zero when I rebuilt the engine. I would imagine rolling forward would be the same process. Just separate the wheels and put them where you'd like. They're pretty simple inside, though getting everything to line back up when you're done can be a PITA.

I was going to roll my back to match the actual miles on the car. Caught all sorts of hell on the board. Then I checked out the gears inside it. Easy as hell, but i didn't need to . I just put my old one in the new gauge cluster. It worked like a charm and was supper easy.
Like Pele said, a monkey go do it.

I did this last night, I succesfully rolled the mileage forward to within 10 miles of the actual mileage. Sadly it was super easy. I am never going to trust a mechanical odometer when I buy a car.
as long as the mileage is exempt on the title and the car is atleast 15yrs or older its legal.(atleast in florida it is) you may need to check with your local rules and regulations.
i"ve done this to quite a few of clusters, it not real hard. you pull the rod out that goes across the numbers clock them were you want them and insert the rod back through the numbers.

.and as DJ said,if you go to the DMV you can fix the recorded mileage to coincide with what is on the car.
Idea.take a pic of you Taking the OLD Speedometer cluster out.(pic of odometer).then take another of the NEW speedometer cluster going IN..Done!.recorded.(leave pic in glove box,and loaded on Laptop).
Why on earth would it be illegal?!?! If all you are doing is matching the Odometer of a used part to the actuall part on your car then I would think that the DMV would be happy. If you roll it back you are breaking the law. If you roll it to be where the milage is matched, you are just making everyones life easier. If you roll it forward past your miles, say 10k, you are an idiot.
just dont talk about it lol
I swapped a jdm cluster into my old 240sx, but if i recall you can jsut switch that part over. resister calibrating the 180kmh speedo into 180mph was awesome lol
