Avcr help

[Jeffers_21]

Ive just installed an avcr and everything is working fine apart from the speed part of it. for some reason it just shows a 0kph all the time. ive check all the wireing but cant work out why its doing it.
 
any ideas?

Mine is the same think its to do with if kmph to mph convertor.

i thought there was a seprate feed to the speedo? i didnt think the speedo came off of the ecu. i might try and take off my speed convertor and see if it makes a diffrence
 
if i cant get it working i think i will try and take a wire from the speed convertor

converter chip should do anything than convert the signal.  The signal travels along the same bit of wiring to the clock face, you just put something inline.

dont think its the convertor i think its the way its been fitted
at least thats what my auto electrition thinks

[Hayward North]

oh wait a mo, dont the avcr have one wire that can be wired for the speed sensor or injector duty, you just have to choose witch one you req ?
so long since i installed it iv forgotten

[Jeffers_21]

naa its the rpm and injector duty wire that is the same. i did my speedo convertor myself and thats just at the back of the clock\'s which is why i dont think it would be that. there inst a wire going back out though to the ecu, well to my knowlage anyway.
 
ive read that some ppl cut the ecu speed wire to get rid of the 112 speed limit. i thought this might have been the case on mine but i cant seem to find anywhere that it might have been cut.

[Hayward North]

i have a wire that is cut but never had the time to trace it

[Jeffers_21]

where abouts is your wire that is cut?

[Jeffers_21]

anyone else got any theorys?
