Outer Limits 4x4 Board

Can anyone recommend me a tacho/instrument guy to calibrate my tacho ?

I have an EMS Stinger 4 ECU with tacho output and can't get the V6 Hilux (3VZ) taco to recognise the signal, so need someone to calibrate/alter the taco so it does.

BTW, have tried 1,2 & 3k Ohm resisters added to the feed, as suggested, but with no joy. Apparently one has/needs a square wave and the other a curved wave which is why they currently have the sh!ts with each other and are not talking

Try Sgesco, they might be able to help you. think they are in Archerfield.

Thanks Dan, will give them a ring

Could also try Lionel Otto instruments, somewhere on the southside if I remember rightly.

Thanks guys, Sgesco were great.
Problem now is they have confirmed/told me there is no signal being sent from the ECU ..... back to square one
