it wont work on a gas tachometer , iba kc yung pulse , ang W terminal is for diesel tachs lang tsaka di cya ganon ka accurate pag sa alternator W terminal . get the OEM ng 2800 td na pajero un lang po masusuggest ko sir

[v22]

thanks for the inputs! will do...

[lowriderz77]

this is the pic of the injection pump as shown with yellow pointers the wiring where you can tap the tachometer, isa wiring na yan which sticks out sa gilid ng injection pump , it gave me most accurate reading. sensya di ko madescribe ung color ng wire kasi im not in manila eh pero 2 lang naman yan eh 1 has the signal needed :D

mine w terminal signal.
lowriderz, san ka ulet kumuha ng signal?

[lowriderz77]

sir , orig pa ba yang alternator mo ? stable nman ang reading ?

[teamsicnarf]

sir , orig pa ba yang alternator mo ? stable nman ang reading ?

yun parin ang oem alternator ko hindi pako nag papalit ng higher amp.
what do you mean stable?
you mean stable bigla sya nag zero during rev or acceleration?
so far hindi sya nag kaganon.
pero theres something bothers me, yung ibang tach meron ceremony once you turn on the ignition switch, yung dsl tach moba meron?
coz akin wala eh just a single flash*shift light..

mga bro i was able to use the normal gas tach for diesel engines,by modifying the tach itself
to accept signal from the ip. nag ADD lang ako ng diode and 2pc of capacitor and nilipat ko yun
green wire sa diode na nilagay ko. yungtach na gamitko yung autogauge din,
post ko details pag available na,kasi for now i want to consolidate my project's data to the
one available sa market,so pls help me guys here, btw my engine is 4d56NA and i used the
magnetic pickup sensor on my ip

1.my tach reads less than or equal 4000rpm b4 i shift gears, is this reading fair enough?

2.my idle rpm is less than 1000.

3.on the expressway *80kph my tach reads 3700 more or less, *1000 kph 4000rpm * 120kph itreas
4100 to 4200rpm

question, does the reading match the reading on diesel tachs installed on yoour ride?

i need your data so that i can calibrate my project to what and how atrue diesel tach reads rpm

[v22]

does this mean its possible to use the orig tacho for a gas engine?

hope you can post more pics and details on your conversion.
