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.

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

deadphoenix52

paid! cant wait

deadphoenix52

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

WAR CRUNK

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.

melstar57

booo....

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

laythor

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

i kid, i kid.

Ryan2008

not cool...




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!

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?

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

deadphoenix52

did you ever add the CEL code feature?

page 8 of the instruction manual

deadphoenix52

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

paulmasoner

iTrader: (1)

then this is not a mod for you...

deadphoenix52

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

zoom44

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

dondo

it works as advertised!

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

AusAndrew

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.
