    Tach adaptor/ step up resistor

    Keen to keep my original instruments with the rb25det I've just installed a TachMatch TM-02-I-Drive unit. it works a treat using the signal output from pin 7 of the ecu

    Tach adaptor/ step up resistor

    Having messaged the guys at tach match and received the following reply have decided to go with one of there units. Indeed you do have a current driven tachometer. The TachMatch TM-02-I-Drive unit will operate your stock tachometer. My understanding is that the RB25 has a tach output signal on pin 7, which is an open-collector output. Being open-collector, it needs a pull-up resistor to get the signal operative. I would recommend a 1.3k ohm pull-up resistor for use with the TachMatch. If you wish, I could install one inside the unit for you at no extra charge. I'm not sure about the maximum sink current on the RB25 pins, I've seen on the internet that folks use 1k resistors sometimes, so I'm presuming that this slightly higher value (1.3k) should be ok, it loads the pin less than 1k. I can't find the actual spec anywhere for your ECU.

    Tach adaptor/ step up resistor

    Any one using a tach adaptor or step up resistor to get there original Rev countre to Work with a ecu output? (RB25det s2 ) Read numerous treads some say they have been able to get it to work others haven't As I would prefer not to swop out the original unit.

    Fuel swirl pot

    Sorry guys I didn't give enough info when posting Car is a 240z standard fuel tank. Engine rb25det standard Using 8mm supply and return pipes Planning on using in line high pressure pump Was kind of thinking that as I will only be using on the road and probably always with a 1/4 tank of fuel min Do I really need a swirl pot set up Mind you wrcbonk you set up look nice and compact don't think I have seen that filter/ tank here in the uk?

    Fuel swirl pot

    I am at the point of installing the fuel supply system. Do I need a swirl pot set up for road use? I am only planning mild running up to 320bhp

    Internal fuel pump

    Looking at fuel pump options for my rb25 install into my S30 240z As the fuel tank is out would I be better fitting an internal pump as apossed to a swirl pot system? Any advise or photos of an install would be a great help.
