Question about 1991 Mitsubishi 3000GT

Open Question

Tachometer failure (Rev counter)

Hi, since I had the delimiter fitted to my 1991 gto, the rev counter went dodgy and inconsistent before failing all together. Anyone have any ideas on what I can check the delimiter wires all look perfectly ok from what I can see. They were wired into the gearboxc sender unit.

    You are confusing me a bit when you call it a "rev counter" The gearbox sending unit is for the speedometer, not the tach, the tach signal is picked up at the coils/PTU.

    And what do you mean by a "de-limiter" Is it something that gets around the redline limit (which is both not a good idea on a stock engine, and is done internal to the ECU) Or is it something that gets around some kind of limit on the top speed (if it hooks into the speedometer sensor, this is my bet)

    I wish I could help more, but without clarification, I can only shoot in the dark.

    Cheers,
    Scott

SOURCE: how to fit a crank sensor to a 1991 GTO twin turbo

Take off Drivers side wheel, remove plastic inner fenders (two pieces - one has six screws and the other is held in with two 12mm bolts - one is hidden up front behind the first plastic cover you remove). Relieve tension from A/C belt (slacken centre nut on tensioner and then using a 12mm ratchet wrench, crank the tensioner in), relieve tension on power steering belt (loosen both bracket bolts and then remove the outer bolt and slide pump up on the arm), place 22mm deep socket on crankshaft pulley and wedge breaker bar on the frame (to the front of the car) and then crank the engine to break the centre bolt. Relieve tension on Timing belt. Remove the crankshaft pulley and tensioner, the crankshaft sensor is located behind the crankshaft pulley. Installation is the reverse of removal, except you have to make sure you put the timing belt back on exactly where it came off (mark the belt and toothed pulley before you pull the belt off) AND you have to pop the tensioner back on so it has the same tension as when you started (the tensioner pops into itself and is spring loaded, held in place with pin/panel pin/small nail while you're working it. Good luck. If you are lost on this, or are asking this because you aren't handy under the hood, leave it to a garage, you will do major damage to your car if you mess up the timing.

At steady speeds the rev counter will drop back a couple of hundred rpm and then bounce back - no change in engine performance


Take it out of overdrive while towing
the Rev counter is known as a Tachometer
if there is truly no change in engine RPM then this could just be a faulty sensor

Hello My 18 year old neighbour bought his first car last week, a '95 Chrysler Stratus 2.0 with manual gear box. Now the tachometer is broken, I was told that there were some plastic parts inside it...


the engine has a rev limiter inbuilt,so after 6250 revs it will cough and sputter.the rev counter is for people who drive to strict rev limits to conserve fuel,and the obvious drivers who drive to the max power/engine revs for "fun"most men drive to the "sound" of the engine,so a rev counter is excess to requirements....save your money.(once he gets his "no claims discount" down he will buy a bmw anyway.........)

Rev counter not working


Suggest that you look for the ground wire of the tachometer gauge. It maybe disconnected. Or else the gauge itself is destroyed.
