Hi all . Just a quick question. I need a tacho booster for my 7mgte in a mx83 , can anyone suggest where i can purchase one from ?

You could also make that

Jeez Wil, thats a bit complicated! I just used the relay coil!
Didn't work for me.Originally Posted by Cool1
And that circuit shown didn't work with any old transistor I pulled out of my junk box either (must of had shite gain)....
Cheers

Your just a useless Tech! The coil works fine on the TA
;P

Maybe a tacho's coolness is inversely related to its age?
ergo old TA tacho = teh shizniz ?

just stop being lazy and spend 40c on a resistor and transistor!!!!

i built one of those booster but it doesnt work too good
i think for memory the guy at disk smith (and he looked like dick smith too ) gave me slight variations in the compents shown in that diagram
for some reason it worked fine on the 4cyl tacho but didnt want to work on the 6cyl tacho.
on the 6cyl tacho, the needle is a bit impotent ....it takes a while to get up. basically it doesnt work to 100% until 4 grand. its a bit floppy below that area. it kind of hovers around all over the place
anyway, i think the moral of the storyis; buy exact components?
hello
frequency response? 'any coil will do' for the inductor coil might be the prob?
someone with elec exp should know.
What ecu + car are you running this in dude? I want to get mine working with my wolf 3d + ta23.Originally Posted by Cool1

3S-GTE + mines ecu if I recall (plug in replacement for the stock ecu) in a TA22.

^^ What He said!
Nice as, mine is only slightly different, I got a ta23 with a 3sge in it.Originally Posted by Cool1
Maybe i haven't looked long enough, but is there a reason why ur using the coil out of a relay? I'm assuming it is more to do with the internal resistance giving a nice current limit with 12 volts across it as opposed to any advantage(?) of it's inductance.
Without testing it i would've guessed at a circuit with the input running through a 2k(ish) ohm resistor into the base of a common NPN BJT (BC337,546 etc) and a small (2k-ish ohm) resistor from 12v down to the collector and the emitter to ground. Take the output from the collector.
why use the coil instead of a resistor???
