There are a couple of things available.

The APEX'i RSM (Rev Speed Meter) will provide speed, revs, trip computer, battery voltage, 1/4mile, 0-100km/hr etc. I have one of these and they work well and look cool. They can also provide power figures if you have the additional g-sensors attached.

The other thing is called a "G-Tech", I think, and provides accurate details on 1/4mile, 0-100's etc.

I would think that most Jap tuning shops could provide you with either.

Lepperfish,

The benefit of the g-sensors is that they correct for wheelspin and provide a rough reading of power output. Although you can get readings of the g-forces exerted in each direction, but by themselves they don't provide much info.

I'd go for the RSM myself... only coz I have one :(

Blue screen, batt voltage and all the other stuff gtst-vspec mentioned. top product. I got mine for $360 :P no G-sensors yet.

you can monitor 4 channels of information aswell, all at once. batt, spead, trip, rev, all that kinda stuff...

and it's got the shift-lite functionality also.. I got a blue LED on the dash that the RSM controls. also has speed alert and a host of other goodies...

some people pay $400 for a tacho with shift light.. the rsm can do it all..

-K.

Most accurate is a Calitec, used to be made by a dude in Sydney I think. Gives 0-60, 0-80, 0-100, 60' with speed in MPH and KPH, 1/4 and speed in MPH and KPH, or you can program it to measure 1/8 mile. Also has two trip meters. Uses magnets on an undriven wheel, and has a G sensor. VERY accurate and repeatable. He was selling them for about $250, but couldn't compete against the Guess-tec and stopped making them. I've had one for about 5 years now and it's really helped me get consistant launches and ET's. :D

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • 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.
