    hey guys. love your work. but is it possible to show a video of how to do it the geared way? pretty please? =)
    my WRX is pre electronically controlled everythings..

    not clear enough, got my dick stuck in-between a spacer and the hub.

  5. mcrsit says:

    The speedo in this car is so retarded, it should be on the rear wheels, rather than on the front ones!

  6. christopher selleck says:

    On the radio people had commented there speed taco is faulty and not working correctly .I think this would take a auto electrician please don't do this at home if a novice .!

  7. Eric Cummings says:

    You can get a ticket in Australia for going 64kph in a 60kph zone? That sucks. Everyone in the US drives like 5mph over the limit on a daily basis, me included. I've never had a speeding ticket.

    why would there be a Volkswagen at a JDM meet?

  9. fourbypete says:

    Anyone know what I can use to correct the speedo on a 2007 JKU Jeep Wrangler diesel. I have an AEV procal but it will only let you change in 1/4" increments. my tire size is 285/75R16 or 32.6"

  10. 01100001a says:

    Hmmm even my old beater 1992 F-150 just requires a few button presses to adjust the speedo. Isn't that standard on all cars?

  11. 7t2z28 says:

    That's insane amount of effort just to "change" the tire size in the vehicle.

  12. yhakult says:

    is the speed reading on gps navigation such as navman accurate?

  13. Jeff Alford says:

    Is it not possible to do the same with an updated Snap On OBD 2 reader ???

  14. EmptySergeant says:

    or just remember that your actual speed is higher

  15. Alejandro Almodovar says:

    Cant you just re-center the speedometer manually considering you know what the cluster and gps nav read? my vehicle would be off by 4 mph easy fix.

  16. TRX VLOGGER says:

    Anyone see 1:52 lol. I think they did that on purpuse to see if anyone is paying attention haha

  17. Hindi sansar says:

    hi boss, while I was trying to fix speedo of Nissan bluebird94 by touching magnet behind it (I saw it somewhere) now it stopped at all even not any light on speedo , so, please tell me what I can do now ?

  18. John Bedard says:

    what is a Volkswagen doing at a jdm meet???

  19. Techno Man says:

    I have a new clusters with Kph & MPH the numbers on cluster are closer together for the Kilometers so when I am driving at 100k my speedo ready 120k but if I am driving at 50 kilometers my speedo reads 30 kilometers. will this tool correct my speedo as well. ?

  20. Cockney John says:

    Nice to see that the steering wheel is on the correct side…

  21. Yordan Sergeev says:

    Ok I ave a MB CLK 2.3K when I drive the highway and my GPS shows lets say 80 the speedo shows 80 as well, when I got to 100 the GPS shows 93, 120 speedo shows 124-25…. when I go to 150 km. on GPS the speedo shows 140 ….. The wills are original 16" size !

  22. Onlyrgu says:

    Thanks this video helped me fixed my (electronic) speedo on my motor bike, I hacked the signal directly from the Tyre sensor.
    P.S. Use multi-meter in DC voltage mode since cars these days are DC !

  23. Jorge Carrillo says:

    Too complicated, just change the design in de speedometer, go to photoshop, recalulate the gauges, and print and stick over the old one… #easy

  24. Kevin Griffin says:

    GPS can be miles out

  25. Laurens Vanhorenbeeck says:

    What app is he using for the speedo ?

  26. Jimmy Gregorio says:

    NO NO NO NO. Solder smoke DOES NOT CONTAIN LEAD. The smoke is unhealthy because of the flux which is cleaning the joint. I fucking HATE when people say that the smoke is dangerous because of lead. You know how hot lead has to be to turn into a gas? 1749C. If you're soldering that hot, then you're doing something seriously wrong.

  27. Jimmy Gregorio says:

    OMG. Don't just cut the wire! That is so stupid! Those connectors have removable inserts that are crimped to the wire, and they're not hard to remove with a thin blade screwdriver. I normally love MCM, but any time they go near electronics I absolutely cringe.

  28. Richard Tester says:

    very cool idea with the I pad I'm most definitely going to do this one thanks guys! !

  29. Thee Adjudicator says:

    But Martin, what if you have just swapped that manky headlining into a another blue turd?

  30. BigBoss says:

    Did you guys ever do a mechanical way to do it?? my car is 1999

  31. Mark McGarret says:

    Or your equivalent

  32. andrej grgic says:


  33. DannyDzNuts says:

    Am I the only one who thinks Marty is maaaad gorgeous?

  34. MyBrothersMario says:

    A 4.4 Km/h (2.7 Mi/h) difference is enough to get a ticket in Australia?! Here a 8Km/h (5Mi/h) difference won't even get you a ticket, well it might, but it's very easily contested.

  35. Omega Tristana says:

    A tip for doing anything with lead smoke is drink a glass of milk right after it will help prevent lead poisoning

  36. George Tempest says:

    digital speedos should be pretty accurate – as for the old analog ones, they ALL show around 10% more in the lower half, same as analog volt meters. So you are spreading a myth guys. When you are doing 50 on the speedo, you are actually only doing 45 – got it?

  37. Jonathan Jennings says:

    4 years on and this is still easily the best intro.

  38. jox mac says:

    Its AC that you messure, So "Set your multimeter to AC volts". Quite important.

  39. IceInMaWeiner says:

    I miss these old bootleg self shot videos.

  40. Jacques Coomans says:

    You guys are great, comedy with seriousness…..what a mix…. tell ya what knackers, yeah the both of ya's, here's a task, I have a Jackaroo 2001 4JX1 turbo and I wanna do some mods, really lol, love this car, come up with some ideas for me, I might even lend it to you's and let you run wild, oh and P.S….. my speedo's out too lol

  41. JP3 says:


  42. Nonno d'acciaio says:

    isn't the speedometer supposed to show more speed than the actual one?

  43. KOakaKO says:

    You can ALSO hold a speed of 60 mph between two signs of a measured mile, which is supposed to be 60 seconds. I don't know if you have measured distances, indicated by signposts (we call them "mile markers" here in the U.S.), in Australia, but that system works pretty well for us here. I timed a 60 mph mile a couple of years back, figured out how far off my pickup speedo was off (after changing tire sizes), bought a new transmission speedo gear on ebay for about a dollar, and now it's accurate to within about 1 mph up to 100 mph. All it takes is a watch, or a phone, or any kind of timer device accurate to the second, and that will give you an accurate 60 mph in 60 seconds. 😉

  44. Daniel Hobson says:

    Mines 5mph slower anyway :/

  45. Aurelius R says:

    Solder smoke DOES NOT contain lead. The reason solder smoke is not good for you is because of the burnt flux, not because of lead.

  46. Aurelius R says:

    Right on! So glad you guys show soldering the correct way (for the most part). You heat both things that are to be soldered together with the iron, then bring the solder in to touch the wires (or whatever), not the iron tip. The solder will just flow onto the connection and you'll have a lovely joint.

  47. Tekno Statik says:

    Ewwwwww, stranger's head slime.

  48. gtdodgeviper says:

    so much easier to just keep in mind that when my speedo says 65 its actually 60

  49. Adrian Yankov says:

    There is also a better way of adjusting the needle with the GPS. We did it with my friend as he was driving with a disassembled dash. He removed the needle with two spoons and then when I told him that we were keeping a constant speed of 60 km/h he installed it back. We did two more runs starting from 0 to random speed and compared to the gps both were showing the exact speed.

  50. identhun says:

    Do not forget, that the car manufacturers do the tachos always ~ 5 Km/H more to show regarding to some international standard.

  51. FCguy says:

    you guys really think there is lead in the smoke … lololol

  52. Steve Gifford says:

    Where is the link to purchase? I have a 2001 Mustang Cobra with new diff gears. Love your shows.

  53. Rex D says:

    "or your equivalent" do women even watch these none of my female friends do so….

  54. Captain Zoll says:

    4:02 car slips off axle stands …

  55. Joseph Stott says:

    they've had lead free solder for donkey's years ya pack of drongo's

  56. Sam says:

    Almost used my monthly data allowance waiting for the 3 hour intro to finish

  57. Hheidi Llabelle says:

    how can i tell if my speedometer is mechanical or electronic? may be a stupid question…

  58. ZausBerg λ says:

    i have the same yellow and black screwdriver XD.

  59. Zep Kleijweg says:

    Does Marty always drive around with the handbrake engaged? https://youtu.be/bMs7w72QTVM?t=9m17s
    Or is that light on because of some mad mod?

  60. drifting1O1 says:

    man why are you guys jacks stands / axles stands week , they looks so old compared to the ones we have in the us

  61. Theo Dokters says:

    Dont dont … dude. That's my job
    Lost it there…. LOL

  62. Tullerion says:

    I miss this car… pity it got crushed 🙁

  63. s74p13s says:

    ha,i just have to change a speedometer gear!

  64. Sp00kMaster says:

    how would you know if your speedometer is controlled electrically or mechanically?

  65. BeastPieDie 6000 says:

    Or in some cars you can just reprogram the ecu

  66. George PMR says:


  67. ChazzFTW says:

    Most cars Speedos say higher speeds than you are actually doing because it makes you think your going faster than you are so you don't speed as much. That's why you can go about 3-5MPH over the speed limit for a speed camera to flash on you. Our BRAND NEW car and our slightly older car has the same offset (I tested it with a GPS Speedo and cruise control

  68. Zohaib Malik says:

    good video

  69. Zohaib Malik says:

    good information

  70. andre tarasoff says:

    Нафиг нужна эта херня?

  71. Serkan Adar says:

    7:07 What track?

  72. YszapHun says:

    for some MAAAAD cluster adjustment!

  73. pedalen says:

    Man, you Aussie's law's are hurting my brain-ball. We have it way easy over here in Sweden. It was going the opposite way in the 80's though, when some idiot politicians decided that if you wanted a modded car – you had to build two, one for chrashtest and one final car. Some Hot Rod enthusiasts killed that idea though, and SFRO was born.

  74. Sak Sittichompoo says:

    Using digital storage oscilloscope would be really nice. If we can see the waveform, we might see how it works. We could even build one ourselves.

  75. Pete Lattimer says:

    or you could just use the online tyre size calculator to work out what size tyres to fit to save all this hassle!
    also, most cars are legally required to read faster than true speed (in Europe at least)

  76. Hee Wei Seng says:

    still watch this in 2017

  77. R176 says:

    Solder sounds so weird when people pronounce the L. I think "sawder" sounds so much less weird.

  78. turtleman cockatoo says:

    hello would this work on a 2000 holden rodeo. this one is discontinued but they have a new version.

  79. MADHUKESH N P says:

    8.36 ….. which is the music being played -.. please can anyone tell me the name of the music/song

  80. SRINIDHI T says:

    is there any aftermarket speedometer and odometer which i can put it on dash

  81. Brandon Foss says:

    i know this is an old video but alldata or equivalent would be a great investment for you guys for stuff like this

  82. Fabio Spiesanzotti says:

    and with bigger weels u loose power and acceleration =P

  83. MrPartyWaffle says:

    My speedometer isn't a percentage off its a solid constant 5 kmph off everywhere.

  84. Al T says:

    don't you go dissing my big wheels trike

  85. Homo sapiens says:

    You should always have in mind "margin of error". All manufacturers deliberately put some percent in every vehicle. There's a quite a bit reasons, and simplest one is driving vehicles in various temperature conditions.
    For example, if you driving 60 km/h during winter time and calibrate it on winter, there's a big chance to get a ticket anyway – if you drive 60 km/h on hot summer day.
    And opposite, of course.

  86. Dante Diana says:

    Can't find this kit anywhere anyone know where to get one, tryed eBay, Amazon,MCM shop but no luck.

  87. peteypizzle21 says:

    How do u do this on newer cars, I have 2011 Acura TL and I'm going from 17s to 19s

  88. Angel chan says:

    can u do another youtube then its all about motorcyclemods

  89. Jaydn W says:

    Also for those of us who are rewatching these for fun. Make sure you get your Tachometer/Trip meter adjusted too to show proper mileage for new size

  90. Sajaad Nazim says:

    Hi MCM, where do I get this kit from please? need it delivered in the UK. Cheers !

  91. Tim Williams says:

    I went to public school in Kentucky and don't need the internet to calculate π x D for a tire. Geeeeez, or…. mark the tire and ground, roll it around, mark ground and measure. Nice commerical, although overly dramatic and wordy.

  92. Dustin Nielson says:

    I'm only 40 seconds in but if the answer isn't a sticker on the speedo then WRONG!!

  93. Steve O'Donald says:

    Just a tip for OLD cars.

    I installed this exact same Jaycar kit to my old VK Calais when it chewed out the speed sensor gear, after I changed a dead transmission.
    The original setup was a driven cable to a speed sensor which sent the signal to the dash (combined with the cruise control).

    Seeing as I had no connection from the transmission to the sensor, I attached 4 magnets around the tail shaft with a hall effect sensor, added an extra preamp circuit to "power" it (found it all online, and built myself), and connected it to the original sensor signal wires heading to the dash.

    This was an unexpected, but necessary, and AWESOME mod… its like Holden should have done it like this in the first place!!!

  94. daythatnevacums says:

    can you show us how to install Big Brake Kits

  95. ZMBP says:

    A damn lot easier to just drive at a lower or higher (whatever the difference is) noted speed. ie my car is 10% too slow so I drive about 5% above the dial indicated speed and I know I'm close enough but still legal. eg drive at indicated 85km and it's just a tad under 80km real speed. There's never an excuse to speed and risk a speeding ticket from a radar.
    All this was just too much effort.

  96. Joyson Wildhart says:

    its an old video but i just wanted to say, here in texas most cops dont care about plus or minus 5 mph

  97. John Lamb says:

    You should update this video with the pre-assembled unit. https://www.jaycar.com.au/corrector-speedo-module/p/AA0376

  98. Luke Jeffress says:

    If I was doing this with a VZ would it still work as it has a digital display as well as the analog. Thanks
