The GOODbox
 

As detailed in this thread: https://www.rx8club.com/series-i-tech-garage-22/my-invention-best-boost-can-gauge-ever-oem-red-lcd-display-195323/#post3520268

[links removed, long since obsolete] This will get you the GOODbox, the wiring harness, 8 T-tap connectors, 8 spade-style connectors and 2 pairs of bullet-style connectors. Shipping is included.

There are a total of 47 for sale, first come first serve

Thanks guys for all your support and feedback during the development period!

Edit: For international orders, please include $20 shipping.
Edit: This for the Series 1 RX8, upto and including 2008 model year. It *might* work on a 2009 but I do not have one to test with, so I can't be sure.
Edit: The GOODbox is not compatible with aftermarket headunits like the metra or corksport kit.

1 for me

oops gottta wait a couple days for the new cc.

You just got paid Pieter. Thanks!

So after all of these sell is that it???

If they sell out, I can always have more made. But there will be a 3 week turn around time. Alternatively I might just release the schematics and firmware, and let people go nuts

Whew, okay thats good, lol... you scared me at first, im not gonna have enough $$$ at first to buy it... thanks man and great product :icon_tup:

Payment and PM sent!

I've been waiting for this.

got PP? :cwm27:

Paypal payment completed

hmmm may pay you very shortly, have to check money first

+1 for me.

Very ingenious.

Geesh, can you program one to work with a Prosport oil pressure gauge and oil temp gauge? :) Instructions look very difficult but it's awesome you have the two analog inputs.

Please let me know if you sell out, I want one but I have some stuff to buy first :)

wow man after all that work 220 is to cheap don't get me wrong!!!!!
but this thing is great compared to rb gauges

Feel free to pay me more :mdrmed:

hahahahaha thanks i hope not one tells you that is to much!!!!

Paypal'ed!

tempted.. but unsure if it'll work with my corksport dash kit. all the factory harnesses are still there..... hmmmm

I can't remember if this was addressed in the other thread or not, but will this work for the Mazda 3 as-is?

No, this only work for the 2003-2008 RX8

:icon_droo That would be awesome!
Or allow people to buy a kit with all the components and PCB to solder themselves.
This would take away the SMT manufacturing processes.

perhaps you have answered this, does it do mpg display?
If not can i use a flow sensor to feed the 0-5v analog input

It does not. I've tried calculating it from the MAF, air/fuel and speed, but it is wildly inaccurate that way. I don't think we want to look at the mpg anyway haha.

Man I wish I could get my oil temp and oil pressure gauge to work with this. I read the directions and it might as well be in Greek as far as the aux inputs are concerned :)

It really isn't too bad. You just have to know how the voltage from the sensor maps to the temp/pressure. So if you have 2.3Volts from the oil pressure sensor, what is the pressure that that represents? You would use the gauge you have now to determine this.

Hmmmm, If I give the manufacture of the sending units/gauges can you figure it out and sell as a package? To have all the data currently and oil pressure and oil temp would be perfect.

No I would need to measure the voltage on your car while it is running. If you think you can't figure it out, your best bet is to ask someone you know who is more familiar with this kind of stuff

Yeah, I will have to find a real electronics guy locally. Maybe I will see if the BHR crew can figure it out, I'm probably gonna roll out that way soon enough.

radioshack multimeter ftw 9k...

I will look into this and see what I can figure out.

paid! cant wait

i also have the corksport. i bit. if you want ill let you know

since the display reads on startup im fairly certain it will work

im in give me a day to get the cash

Hello,

You mentioned that these weren't compatible for the mazda3's - does this include the speed3's too?

Is it because you dont have the instructions for the MS3's or was there an actual wiring problem??

I really want to jump on this and pick one up if it will work.

Thanks!

No, it will not work. Although the 3 uses the same LCD, the display module communicates with the rest of the car completely differently. I would have to design a different circuit board to work with the 3 and/or 6.

booo....

so when can we expect the new circuit board to be released :naughty:

lol.. sent you a PM.. then immediatly said "f-it" and sent my paypal in. This is gonna be great if it works.. otherwise i'll have a never used goodbox for sale for 400 bucks after these all sell out :rock:

i kid, i kid.

:suspect: not cool...

:p:


Thanks for the PM pieter3d, will have funds soon! Great product as I said before!

In the meantime, I know he has very detailed install instructions, but if anyone can find any tricks or anything while installing, definitely post up!

Ryan :smoker:

Standard sensors are simply variable resisitors. They vary in response to what they are measuring. (My oil pressure sensor varies from 3 to ~160 ohms as the pressure varies from 0-10 bar if I'm remembering right.) A sensor by itself doesn't produce a voltage, that has to come from somewhere else. (Volts = Current x Resistance). One has to either supply a constant voltage and measure a change in current, or a constant current and measure the change in voltage. Classic cheap gauges are basically am(p)meters which use the ~14.7 constant voltage from the battery to measure the changing current caused by the variable resistance of the sensor. In other words, there is no way to tap a variable voltage signal for input to the Goodbox from a "classic" cheap gauge set.

Do "modern" cheap gauges work differently? IE, by internally incorporating a constant-current power supply to produce a voltage that varies with the changing resistance of the sensor? If that's the case, then tapping the voltage line of the gauge will work if the signal range falls in the 0-5V range. But then, having the gauge installed is required to get the Goodbox signal, which kinds defeats the purpose of having a Goodbox in the first place.

It seems to me then to get an oil pressure or temp signal without having a gauge installed either requires a little independant constant-current power supply to run the sensor circuit, or using battery voltage together with a little ammeter with an appropriate voltage output.

Am I thinking right or am I stuck in the Edison-era?

(Payment sent by the way!)

HiFlight, all you gotta do is look :)

this is just a random pressure sensor i looked up

http://www.senzors.com/us/products/h...ts/hiprecision

if you know what you are looking for, you can put damn near any "gauge" you want on this thing... 0-5V output is so damn common

did you ever add the CEL code feature?

page 8 of the instruction manual ;)

lol. since there werent pictures i didnt read it....

then this is not a mod for you...

haha. nah, ill read it all once i get the unit in hand

paid!

Good find. What I was trying to point out is there's a bit of a disconnect in the discussion. Page 8 and on in the instruction manual tells what to do with a 0-5V signal, not how to get that signal. What you can't do is wire the goodbox to a standard sensor, at least the 3 different versions I've gotten from summit, glowshift and ebay; they all vary resistance. To make that kind of sensor work, you have to add some electronic stuff. Or, a much better suggestion, use a sensor with a native 0-5v output for the Goodbox as you showed, but then a standard gauge won't work with that. Getting both to work, like 9krpm was talking about, would require some cleverness.

oh, i missed the part about making it work with regular gauges as well.... i feel stupid now....

yeah that will take some doing. it wouldnt be hard from an electrical engineer point of view, but prolly more than most people would want to DIY

it works as advertised!

Nice!!! Can you give me your supercharger so I can see if the boost function works?

Well done and congrats Dondo, first installed! Also good work on quick shipping from Pieter. He's been great organising and shipping to Australia and I can't wait for it to arrive.


I'm interested in this too. I'm planning on hooking up oil temp, but not sure exactly what will work with it, given that I don't already have a gauge.

I still have a couple of weeks, while my unit flies over the ocean, to find a temp sender and sort out potential electrical issues as above.
