Speedometer Problem

I took out my white speedometer kit, in my 94 R33 NA, and after putting it all back together the speedometer doesn't show up the right speed. IT shows up roughly half the speed i'm doing. So when i'm doing 80 it shows roughly 40. The car is running fine, and i don't have a problem with the taco. Any ideas?

My mate took the cluster out of his Toyota and removed the plastic front, put it back in then followed me at 60 according to my speedo. He held the speed, pushed the needle back on at 60 and replaced the plastic front. Been correct ever since.

ahhh quality mechanical work, there's just nothing finer for your 87 camry

Haha see the reason i asked was because i just had my car converted from auto to manual and the automatic cluster reads only half the speed. pretty much exact same problem but different.

I have heard that there is a way to re-calibrate it from the back of the cluster but I'm unsure on how this is done, should probably search it up im sure its been covered at some point. One thing you can try is unplugging the cluster, starting the car, then plugging it back in while its running. This seemed to do the trick with my old tx3 turbo, but i cant guarantee anything.

there is a tutorial on adjusting the cluster on this forum somewhere. it is done by soldering up jumpers on the back of the speedo.

also if you converted the car from auto to manual and didn't change the diff then it will read out as well because the auto diff ratio is different and the speedo reads from the gearbox.

Yeah i had the cluster changed to manual and yes its still running auto diff, i prefer the higher gearing to manual one. Its only out by 3km/h at 60, and 5km/h at 100 (reads lower). Ive checked it out with a couple different gps units. With 18's on it reads perfect again so no problems there for me :D

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
