The RX8 from the factory does not have a real oil pressure or oil temperature sensor, so there is no way for the GOODbox to display those unless you use aftermarket sensors and setup the Aux1/2 analog inputs.

Read the instruction PDF. It reads from the factory computer which has no ability to display oil temp and pressure. With this unit there are two AUX inputs but wiring up oil temp and oil pressure has not been done yet.

I'm curious if these type of sensors are compatible (wiring and correction factors from the PDF used)... Dakota Digital (VDO) digital oil pressure sender

Please read posts #38, #39 and a few beyond of this thread. Summary:

1) Standard automotive senders for op, ot, wt, etc. are resistive - their signal is in OHMS.

2) The goodbox aux inputs require a 0 to 5 VOLT signal.

That sender won't work! (Unless you add some extra electronics.)

HiFlite999, can you figure what will work? Someone please do this, my Prosport Oil Pressure gauge just took a dump, now is the time for me to do this.

pieter3d please review, but I think these $65 units will work fine:

http://www.aemelectronics.com/100-ps...sensor-kit-656

(The AEM gauge products also have a 0-5V output from the gauge head that could be used. Don't confuse a gauge output like that from the output of the sensor itself. Apparently their oil pressure sender *does* output a real 0-5v signal, but their temperature senders *do not*.)

These particular units even come with the transfer function that you'll need to code into the goodbox. 0-100 psi is fine for a stock oil system. For $100 more (yikes) you can get it in stainless steel. A quick clue that this is *not* a standard resistive sensor is the 3-wire hookup vs the usual 1 or 2 wires.

Many of the other references I've found are much more for OEM use, for example:

http://search.digikey.com/scripts/Dk...me=480-2581-ND

$106 for one; $19,202 for 250 (group buy??) :D:

Verify with pieter3d though before buying, 'cause he's the engineer, not me ...

The AEM sensor would work just fine, provided you can get it onto the engine somehow. However it requires a 5V supply voltage, so you still have to figure that out somehow.

So for over 100 PSI the AEM would not work? I see above 140psi at redline.

I already have an oil filter adapter plate with an oil pressure sensor and oil temp sensor in it.

This is who makes my oil temp gauge, will these work? I think so but need clarification.

Dude, just get a multimeter and measure the voltage going to your gauge, broken or not. If it stays under 5V, it should be fine.

just got mine in the mail! installation will commence tomorrow or tonight. eagerly awaiting for peeps to figure out what oil sensors will work and how. because i know nothing of computers and electronics.

Oops, missed that. The standard Prosport adapter plate has 1/8" NPT so fitting isn't an issue. Would have to scare up a 12V to 5V converter.

The oil pressure sender would work, but has the same problem in requiring a 5V power source.

The temperature sender 99% sure won't work. Getting a temperature sensor with a "native" 0-5V linear output will be hard.

a) Do you want to have gauges + the goodbox display?
Or (b) do you want the goodbox display to replace the gauge entirely?

just got mine today.. will have it installed monday or tuesday

I would at least like to eliminate my oil pressure gauge. I am ok keeping the Auber oil temp gauge since it's mounted in the radio and doesn't stand out. Then I'll use whoneedspistons new pod for EGT, Oil Temp, and Nitrous.

I'm definately in the (b) category, I want an oil temp display on my GOODBox and nowhere else.

It seems that all we will need is a temp/pressure sender with a native 0-5v output and some way to get a 5v power supply to it. This sounds simple enough in theory, but I hope someone else can elaborate on how/if it will work in practice?

If anyone gets it working (or expects to), I'm sure a link to what will work would be beneficial to others here.


EDIT: Maybe we should take this discussion to the orignal thread and leave this for the group buy itself?

AFAIK Neither OIL Temp or OIL Pressure can be monitored with the GoodBox for a Series 1 with OEM sensors as your cars PCM does not monitor the variables in Voltage to measure Oil Pressure and or Oil Temps (OEM has no Oil Temp Sensor)...in other words, if a ScanGauge and any OBD Reader does not include these two neither can this Great GoodBox, again as it is taking the same standard "signals" from PCM just like a ScanGauge or OBD+Key does.

The Series 2, Oil Pressure Sensor is mounted on #1 EMOP (electric metering oil pump),it does report Voltage Resistance to the PCM, it determines Voltage as Oil Pressure (7 to 21 PSI Approx, inside EMOP) the higher the Voltage the Higher the Oil Pressure or Lower the Voltage the Lower the Oil Pressure, if there is a problem with engine Oil Pressure in Series 2 you get a constant Warning Lamp if too low, and or the same warning lamp flashes if there is an Oil Supply or Control Malfunction at EMOP.

Unfortunately it appears this can not also be read at OBD, well not with the OBD+Key Reader I use for my car.

Pieter, may be able to access these Voltage readouts if he is given the correct "Numbers" from a S2??

The Sensor for S1's (Under Oil Filter) AFAIK just registers a Drop or Low Voltage from Low Oil Pressure/Level, hence the dash warning light.

Sorry for my simpleton speak..

Sorry guys, should have read last thread page here /\ /\...Dam the email Updates! :)

This is true, but Pieter has included spots to add additional sensors (not provided by Mazda) and there is some discussion as to how this would work.


EDIT:
And I should have given you a few moments before responding.

Yep...Just what I thought Pieter...S2 Does have Real OP...

No Problems mate..I or should I say we do it all the time...Australia is a long way away...lol:eek:

Okay, that's the easy one to eliminate. You'd just have to add a 12V to 5V converter to power the
http://www.aemelectronics.com/150-ps...sensor-kit-659 sensor.

Pressure sensors like this are findable, temperature sensors are all resistive. I think by putting a "step up" resistor in a circuit powered at 5V, the normal aftermarket sensors can be made to work. I have to think about this a little and dig up a few bits of hardware. My Goodbox arrived last night, so maybe I can come up with a working example in a week or so.

Agreed on both points.

None of this discussion should imply anything negative about the Goodbox itself. Pieter3d has come up with a great gadget. Of course in releasing it to compulsive mod freaks, twiddling afterward is guaranteed!

Maybe you can start a thread on your install/build. I have to pay for my Cobb this payday and then I am ordering.

I was at least expecting it to be gold plated :suspect:

j/k

Too bad it only has boost and not vacuum too ....

measuring oil pressure on a Renesis is a total waste, especially when you haven't even bothered to measure fuel pressure yet ...
