So what did you find out in a month? Not much by the sounds of it, if you needed to be told the speedo runs off the wheel speed sensor/s
Why wait, plug it in now and see what you can see with your reader. Then at least you will know if it is possible to monitor.
I have at no point implied any RPM or speed, I focus on the physical fit side of the question.
I suppose I did mention it was a big ratio change at the beginning to be fair, but you then pointed out you had such a mechanical knowledge I thought "well this guy understands"
You also learnt it here on the same day from the guy you are now calling an idiot.
I would have thought that after researching for a month you would have got the technical manual that would explain the process.
I have already said I dont see why they wont fit even down to the fact the O ring seal behind the front diff is the same, but that some bolt lengths are different. But driveshafts may or maynot be the same. of course I did find the info I provided to you in less than a month.
Technically no, you answered some yes. I dont think you answered any of mine with anything but disdain.
But of course google chat bot gives all your answers as has been seen many times here. Myself I prefer a technical manual, or others experience. But you wont even take that even though you are asking for it.
You have a Range Rover, much to your disgust it has many ECUs for things. My 1996 Range rover is the same (decades old we say) it too runs its speedo off the wheel speed sensors.
Your post about the output shaft sensor, Was this autobox related? Because yes, yet again I pointed out to you that they have 2 input & output, but I believe that they are only used for the gearbox ECU for shifts and TC lockup.
Some are refered to as "road speed" sensor some just "output shaft speed" They are called many different names.
I dont have enough knowledge to argue eaxactly what they do. But you had better hope that yours does not use that sensor with the wheel speed sensor as a coralation for the speedo as it will likely throw a hissy fit.
I will leave you to your google expert.
Have a nice time laughing at my post like you will. but if you want to ask about anything technical I am all ears.
Have a great day
