bro bnr_32..RB20 gearbox using speedo cable bro and your r34 cluster need signal from speed sensor.. and why your speed sensor located at rear axle?
owh ok now i understand.. i tot your car came with rb25 auto and u switch to rb20 manual gearbox from r32.. your case is car came with rb20 manual and u change the engine to rb25 and retain the rb20 manual gearbox right? if that the case than it shouldn't be any problem speed sensor pulse x ngam.. mebbe like vspec said that your speed sensor faulty.. at the pivot speed meter after set it to n2 does it have the same symptom?bro bnr_32..
Sorry bt i dun really knw in detail of the speed sensor and speedo cable.. i just quote the worksyop guy.. he told me that my rear LSD is a double LSD or something(guess this got nothing to do with the mileage and meter)...hehehe... so not clever of me...
btw,can u teach me what i shud do? but, totally, the car was being chop off from half cut shop and the problem is that i cudnt get my speedometer to work well (ofcourse the speedo work but up untill 100kmh, after that, the reading is all over the place) therefore spoil my mileage reading...
Really Need help and advise for this issue...
Any word of advise?
Anything to check and recheck?
Cheers bro!
Sorry bro bnr_32 for my worst explanation...owh ok now i understand.. i tot your car came with rb25 auto and u switch to rb20 manual gearbox from r32.. your case is car came with rb20 manual and u change the engine to rb25 and retain the rb20 manual gearbox right? if that the case than it shouldn't be any problem speed sensor pulse x ngam.. mebbe like vspec said that your speed sensor faulty.. at the pivot speed meter after set it to n2 does it have the same symptom?
Bro Atermizi,Bro i had similar issue because rb20 speed sensor is not compatible with r34..so you'll bounce off 180 whilw ur doing 100 kmh n spped limiter kicks in..n ur odomter rolls like crazy
Options are
1.remove the sensor frm the gearbox n just estimate the speed based on rpm..
2.get an rb25 gearbox..
Physically to can see the diffrent size between rb20 n rb25 gearbox
Thanks so much for the information. So, basically i cannot get any response for the speedometer if i remove the sensor... darn!! there goes my speedometer... the pivot meter gets the reading from the ECU and the ECU gets the reading from the speed sensor. i doubt that the speed sensor is at fault,since i still can read the speedometer functions and the odometer is still function... Any chance to rectify the problem without buying a new MT Gearbox? is it possible to remove the CUT OFF with the speed sensor in place? Its hard to move around without knowing how fast your car can go.. hehehe...Yes if u remove the sensor u wont any speed/odometer reading thus no speed limit also.I dont think ur pivot meter will read anything unless it reads speed from sattelite like Vbox or gps. It the meantime enjoy the pickup of short ratio rb20 Gbox. Remember u'll need to modify ur shaft n gearbox mount for rb25.
