Exhaust Temp , A/F MIX gauges.
Intake temp sensors pre cooler and post cooler gauges.
Map.
Knock voltage
Atmospheric temp
G force
Just about any parrameter you want can be measured and detailed depending on your wallet.
Best to do all temps (oil ,water ,exahust), oil pressure , A/F , IAT, map knock.

Take the sandwich plate off and work out which way the oil flows.  Out of the engine, into one part of the plate or the other, out through some hole, back through the other, etc etc.

good call!

Maybe I mis-read the diagrams, or I don't have a Greddy sandwich plate, but during the track session today, checking the temperature on the outside of the braided lines going to/from the cooler showed a 8-10 degree difference - but the line I thought was coming from the engine was the cooler line. I checked it numerous times just to be sure - a consistent 8-10 degree difference.

I'll put the temp sensor into the hot side - but I'll go back through all the diagrams to see how I got it wrong...based on the temperature readings the blank plug is on the correct side to tap for the new sensor (1/8 NPT tap on it's way via eBay).

cheers

ongoing noob questions...

it looks like the oil from the engine goes out the right hand side port - is this correct?

cheers,

I would say yes.  The central port is the return to the engine, which means the outer oil path facing the camera is dirty oil into filter.  The thermostat bypass is from the right hand port back into that outer path.  Otherwise, when the thermostat is working (hot), the oil will go out that side and come back on the left to the dirty side of the filter.  So your conclusion looks correct.

thanks GTSBoy - that lines up with my "updated" view of how the sandwich plate works and the temperature of the lines to/from the cooler...

My original understanding was incorrect.

Just waiting for my 1/8 NPT tap to arrive to get the sensor installed.

cheers

      Does anyone know whats happening with harness on drivers door?

      The two diagrams are equivalent. The R32 one is just one sheet out of about 3 showing everything in the whole car all at once. And without knowing the functionality that occurs in the modules, they are both equally opaque.

      8v - 2.48ms 9v - 2.15ms 10v - 1.74ms 11v - 1.41ms 12v - 1.15ms 13v - 0.99ms 14v - 0.89ms 15v - 0.82ms 16v - 0.81ms I'm running these values on my RB20 Neo with 570cc Denso R35 stock jets and it's great. Also bought a set for my Legnum VR4, love these injectors!

      Thanks for your reply,  Those blue/green wires running to the actuator aren't attached to anything, so I'm not sure how the central locking is still working. I will have to take a good look tomorrow, I don't have the car with me. After googling it seems like a pretty common aftermarket actuator which even uses the same green/blue wires the immobiliser required. i'll test everything tomorrow and if it's working i'll melt the solder, strip it, resolder and neaten it all up with some heat shrink. I don't have to understand it if it works hahaha I just don't want a fire/ short circuit. That R32 diagram looks more like a continuity chart? Can you make sense of this form the R34 manual? 10V is probably due to very flat battery, i'll recheck as well tomorrow, I did have to jump start it haha. Thanks again!

      So, COM doesn't mean comms. It means common. What common itself means will depend on the type of device. For a two directional actuator (ie, one that can push and pull on the same output rod) then the common will typically just be the earth connection. There will be at least 2 other wires. If you put 12V on one of the other wires, then the actuator will push. On the other 12V wire, it will pull. Can't quite make out what is going on with the wiring of your actuator. It appears to have several wires at the actuator plug, but there only appears to be 2 wires where its loom approaches the door control module, with at least one of the others cut off. I don't know these actuators off by heart. I'd have to look at a wiring diagram for one before knowing what the wires were about, and that's despite me having to replace one in my car not all that long ago. Just not interesting enough to have dedicated memory set aside for trivia like that any more. That actuator is an aftermarket one, not the original one, which probably died and was replaced. That might require some sort of bodge job on wiring to make it work. Although nothing should justify the bodginess of the bodge job done. As to the soldering job on the door module's loom plug. Ahhahhahaha. Yes, very nasty. Again, I cant tell you what any of those wires do. You'd need to study the R34 wiring diagram (if you can find one that shows the door module). I don't think I have any. I'd have to study the R32 diagram to start to understand what mine is doing, and again, even though I've had a problem with mine for the last 25 years (where it locks the passenger door when the driver's window reaches top or bottom of travel) I'm just not interested enough to try to to work it out. So long as it's not burning down, it's fine with me. Here's the R32 GTR diagram, which, confusingly, has rear door lock actuators and window motors on it!! As you can see, unless you understand the functions of the door lock timer and the power window amplifier, you'll never be able to work out how it works just from the diagram. I don't imagine that the R34 one is any better. Hopefully an R34 aware bod can help. FWIW, the two wires that are cut and joined look like they are both power supply - so hopefully it is not fatal to join them. The 10V you measured on the cut off free end of one of them is concerning. You'd expect 12V, and it might be the reason for the bodge job joining them together.
