GOODBox is leveraging off the SPI bus, S2 display is controlled via the CAN messaging, therefore they are not compatible.

 

Good to know. Now I am back to waiting on you, Paimon.

It was 112 today. Having the temperature read 70 was just insulting.

 

Having finally tracked down some "linear" sensors, I was able to port oil temp and pressure to the display. I used an AEM sender for pressure and a PLX setup for temp. I had fun with the multiplier / offset calculations so if you use the same sensors, here they are. With the exceptiom of wire, shrink tubing, tape etc., this is all the parts required. I mounted the 5v supply inside the PLX box and ran a 5 wire harness to the sensor plate (routed through the shifter boot as RB does). Be sure to wrap the harness flat at the shifter boot plate and use a little foam tape to avoid pinching the wire.

Parts:
Racing Beat Oil Pressure & Temperature Sensor Adapter 11803

Oil Temperature:
PLX Devices iMFD Sensor Module SM-FluidTemp
3/8" Brass Flat Washer (for clearance)

Multiplier: 264 Offset: 32

Oil Pressure:
AEM 30-2131-150 150 PSIG Brass Sensor Kit
Reducing Bushing, 3/8" NPT Male X 1/8" NPT Female
5v supply ROHM BA17805T

Multiplier: 183 Offset: -19

 

After testing and comparing temps and pressures I pulled my RB gauges and reinstalled the ashtray. This set up seems plenty accurate and is easier to read.

 

Awesome, thanks for sharing.

 

Hey 9k, did you ever get your "slot machine" problem fixed?
I know it's been a while, but my goodbox still does it ocassionally.
I still power cycle mine.

 

Nope, been too lazy to mess with it. It rarely happens so I have bothered to mess with it.

 

I find it almost never happens if I don't go from 'off' to 'start' in one step, but deliberately pause a second at 'acc' and 'on'. Also, it will happen if I shut the car down with the nav hood open, so that when I turn the key, the nav hood motor is running.

 

I need one in my car.

 

still for sale?

 

I had a new, unused one FS here forever for only 2/3 what I paid for it, finally traded it last week for my next mod ...

 

I would really like to find one of these

 

PM Dondo and get him moving

 

He was producing and selling more recently, there's a thread on here somewhere. My own experience that it was less effort to sell mine than deal with him. Good luck.

 

PM me if you have any inquiries on the Goodbox.

 

What is the status on these?

 

I love mine, if you want one, PM member Dondo.

 

Fixed.

 

So I finally got around to installing this Oil temperature sensor and giving it a go at working with the GoodBox. At first I thought things were working, but I realized that the ADC was maxing out at 3.5VDC. Has anyone else had this issue?

Basically I Am monitoring the voltage with my meter, comparing it to the graph provided with the sender unit and them comparing the raw values the GoodBox is showing. When My multimeter reads 3.5VDC the GoodBox is maxing at 1023 and, showing me the max temperature+offset value (in my case it's showing 214F). According the the AeroForce graph 3.5V should be somewhere around 190.0 And this shows true in my readings...as soon as the goodbox reads 189 the next step it takes is maxing out and showing 200+.

 

Wow, and I thought I worked slowly... 4 years to get around to fitting that sensor?

I have been using those Aeroforce sensors with my GOODbox for years now. Working just as perfectly now as the day I fitted them. Definitely no problem with them reading over 190F.

Given that the raw voltage output from your sensor correlates appropriately with the temperature, the problem points to the GOODbox. Either it's a software problem interpolating the voltage into the 0-1023 'raw' value, or perhaps the ADC in the chip is fried. I think Pieter did mention somewhere back in this thread that there was a risk of frying the ADC if it ever received more than 5 volts.

 

Would you mind providing me with the offset and multiplier values you used? Instead of using the values from their sheet I characterized the sensor using a thermometer in a bucket of boiling water that I added ice to.

EDIT: For the record I have had the sensor plugged into the sandwich plate for close to 3 years. However I wasn't looking forward to the characterization of the sensor so much that I just put off running the cables and hooking up the regulator.

 

I posted them in this very thread, back on page 14

 

BAH, thanks man. I knew I had seen it somewhere, but I REALLY didn't want to have to dig through all of the pages again. I'll give it a try.

 

So I plugged in the 0271 multiplier and 0 offset and got what seems to be normal readings up to a point. So The oil temp seems to track pretty well with the coolant temperature, albeit slower. However, I am finding that after 5-10 minutes of driving the raw values reads 0000 and the temp read 208F for quite some time. My outside temp was 95 yesterday so 208F seems about right for highway. After I hit a couple of stoplights I noticed the raw values started climbing again. The were no longer approaching 1023, but were starting from 0000 and increasing. The reported temperature was also going up to 210, then 212 before I started moving again.

This seems weird to me...

 

One thing that can cause calibration errors and/or inconsistent results is a ground loop. This comes from different devices being grounded at different points on the chassis. The solution is to bring the probe ground back on a separate wire and attach it to the same wire as the GoodBox.
