is the problem likly to be with puse generator on gearbox or kph mph converter in dash
Either one would cause your problem. easiest option is bypass the kph/mph converter see if that cures it then go from there.
Kevin
thanks
so cruse contole feed is of speedo not of puse jenerator directly
will have to strip down dash and have a look
Not 100% sure on rx7 but normally the feed enters the car in the ecu loom then splits from there.
Kevin
so probably puse jenerator
depends a lot where in the loom the converter is wired in. Go with the easy option first which is bypassing the converter.
Kevin
will have to fined the converter any idear what thay look like?
Do a search on ebay then you can see the pics they are normally wired in the passenger footwell.
Kevin
had a good look round and cant find it in the car yet any idear how close to ecu thay are normaly
ed
its down to whoever does the wiring to be honest most wire it in that area because it is easy to get to and out of the weather.
Kevin
been reading wireing diagram for 94 lhd and looks like pulse generator feeds cloks and thgen cloks feed ecu and cruse so will folow mack root checking from ther ( will check at harnes plug under dash
ed
it will prob be behind the clocks or in the passanger foot well in the loom that plugs into the main engine loom, id start at the clocks as its easy and then take the passanger seat out and check under the dash. dont for get the chip can be as small as your little finger nail.
matt
found converter and not the problem

ed
glad it was an easy fix for you bud.
