Guy I'm attaching a heltech 2000 pro to the standard oil presure sensor getting a reading but dont know what scale to set the heltech to???? Example what voltage is say 40 pound ?????

Guy I'm attaching a heltech 2000 pro to the standard oil presure sensor getting a reading but dont know what scale to set the heltech to???? Example what voltage is say 40 pound ?????

I have the r32 gtr oil sensor

The stock gauge reads in kg/cm2, then just use: http://wiki.xtronics.com/index.php/Pressure_Conversion_Table

1kg/cm2 for example is close to 1bar which in turn is about 14.x psi

convert kg/cm2 to whatever pressure you prefer, psi, bar etc

no he means

at 1.0v what is the pressure ie 1.05kgcm2

at 1.1v what is the pressure and so on 1.15 kgcm2

it would be documented somewhere, not sure where tho

you could always use a mulitmeter and linear scale it yourself

according to service maunal at idle of 800rpm it should be 1.5kgcm2 for RB26DETT

no idea if you have std oil pump or other shit modified, but you could use that as base

ie warm up engine

drive around

come back to garage

let it idle for a minute

take that voltage as base and assume it is 1.5kgcm2 and you have fairly basic comparison

no idea if its linear or not ie lets say 1.5kcm2 is 1.0 not sure if 2.0v is 3.0kgcm2

problem is paul we are not useing the standard gauge so what we are do is inputing it to the IQ3 digi dash and that want us to give it a scale to then convert to signal the dash wants??????

Or measure it with a multimeter and have an electronic/mechanical gauge hooked up and read both for nodes throughout the range, plot this up and get a line of best fit for oil pressure vs voltage and apply this to the haltech. I doubt it would be a straight line fit.

not sure if this helps but a lot of electronic gauges have a sender unit that sends a voltage signal to the gauge, would one of them do it for you?

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
