qha_vn Posted February 12, 2007 Share Posted February 12, 2007 the ex-owner of my 1990 LS400 had changed the rims from original 15 to 16" which in turn makes the speedo meter indicates wrong speed display. GPS shows 100km/h while the speedo tells 80km/h :cries: given that the 93-94 model use 16" rims, should i replace my current speed sensor with the 93-94 one? are they compatible? thanks for any advise Quote Link to comment Share on other sites More sharing options...
bartkat Posted February 12, 2007 Share Posted February 12, 2007 Maybe go to lower profile tires to get the same revolutions per mile. Quote Link to comment Share on other sites More sharing options...
qha_vn Posted February 12, 2007 Author Share Posted February 12, 2007 but it would require 4 new tires (existing ones are still in good condition) Quote Link to comment Share on other sites More sharing options...
92Lex Posted February 13, 2007 Share Posted February 13, 2007 20km/hr difference seems high for a +1" rim. Are you sure that the GPS is accurate? How are the roads in VN? I haven't been back there for years. Quote Link to comment Share on other sites More sharing options...
qha_vn Posted February 13, 2007 Author Share Posted February 13, 2007 Hi 92Lex, might be both inaccurate :-( where can i look into? VN road is getting better, vehicle has recently got a plus of 10-20 km/h to max speed your from VN? Quote Link to comment Share on other sites More sharing options...
92Lex Posted February 13, 2007 Share Posted February 13, 2007 Try putting 15" rims back on your car, to see if the GPS is accurate. I was born in Da Nang. My last vacation to VN was almost 9 years ago. Your English is pretty good...were you taught at school, in VN? Quote Link to comment Share on other sites More sharing options...
qha_vn Posted February 13, 2007 Author Share Posted February 13, 2007 will a 93-94 speed sensor work for me (1990)? compare on 15" rims is a good idea, give will it a try thanks for your comment on my English, yes i was taught in VN. i am living in HCM, if you are back to VN, lets have a drink :) Quote Link to comment Share on other sites More sharing options...
92Lex Posted February 13, 2007 Share Posted February 13, 2007 I'm not sure if a 93-94 speed sensor would work with your application. 90-94's platform are basically the same but I'm not sure if the electrical components remained unchanged. Maybe someone could chime in? HCM? I still consider it Saigon. Haha. My friends and I were planning a trip back there this summer. If everything goes as planned then I'll be seeing you soon. I had a plan to have body kits produced in VN and have them shipped to the states. I can provide the mold. Do you happen to know people over there that can make this happen for me?
