Another question is does the headlight noise sound when you leave the lights on and open the door? I know the the VX signals to earth when the doors are shut rather than the opposite so it's a pain trying to get anything to work here.

Sorry , headlight noise is gone .

Is there a way round this with your dash? It's so annoying with my digital dash now that the alarm won't sound when I've left my lights on. Fitting a alarm buzzer to the headlight switch/door popper doesn't work.

Could the PWM input for the temp gauge be configured to work at a different frequency?

I choose to average the analogue value from the pwm instead of measuring the duty cycle of the pwm This allows it to work with both analogue and pwm inputs , What would be reason to change the frequency ? More background to the question please :-)

The vx220 Pwm output from the ecu is not linear in its behaviour so while the average value will give something, it won't represent the actual temp. There is a thread a page or so in from here with a link to some scope readings from it

The averaging of the analogue value will represent the duty cycle % in the same way . I used the Elise S2 k series to work out the pwm , which seemed pretty linear when tested with a pwm input to the cluster . I will test the original vx clusters temp reading vs pwm input .  

    To add more detail to this - I am moving to the Omex 600 ECU for my Webcon throttle bodied car in May and it is capable of being configured to output 1 PWM frequency of either 250, 125, 84 etc but not 100 which is what the Stack temp gauge uses.     However, thinking about this, if we are taking out the Stack dash, do we even need PWM for this?  The Webcon kit has two water temp sensors and I wonder if we can hook into either one of these to feed the new LCD dash?    

Use the can output of the ecu for all its data Do s the omex have can

[TheHood]

IRC the Omex has two temp inputs but only switches for output. Wild guess, but since this gauge is just mensuring a mean analogue value there's probably nothing stopping us going for 125hz and programming tge PWM auxiliary out accordingly.

[slindborg]

I would imagine that the Omex PWM output will be linear and proper, so I'd stick my neck out and say that based on Garw's posts, it will read that just fine.

 

Its the stupid relationship of the temp to PWM form that the VX/Mk4 astra ECU has that might post some inaccuracies for standard folks. The likely reality is that it wont matter that much for 95% of users

Another wonderful VX mod for which I really have no need, but a whole lot of want..

Not sure what the issue is here , i need to confirm the door switch states first , as i was sure its a normally closed switch

have fun

 

i like the phone screen window idea

[CHILL Gone DUTCH]

could it work with a sat nav screen to ?

[Andy_VX]

This looks very good, I've always wanted a proper display that looks a bit more OEM. I'll follow progress with interest.

If you can figure this out I would be interested in one as this would temp me 😁

For a visual guide the non linear behavior is not important

 

the range we are interested in is linear and the fact the maths are wrong under 50 Deg C and over 110 doesn't matter 

 

ecu's need to get it exact across the full temp range as this data is very important for fueling correctly at all times.

 

I will scope the VX between the visual range and see what error exists if any 

[ditonics]

Is this was answered i missed it. Will it be able to display obd2 data - map, maf, mat, fuel trims, timing etc

[haggi961]

Can this run Windows? A feature I would love and I reckon a lot of others would also, would be to run obd tuner through this and then getting rid of the tablet.

  the door switches simply connect to ground. A buzzer with a 12v sourched from the lights power and switched to ground by the doors does the job. All needed connections are at the dash connector. https://www.speedste...tact switch.pdf

Once it's in my car and Alec's car we will be looking at stuff like the navigation so watch this space. Should be easy to cast to a dongle and take the HDMI output, convert it into composite and use it like a background. I think there needs to be some control over miles though or we'll end up seeing a lot of clocked cars lol!

I've fitted 3 different types of buzzers with this method and after a couple of days the buzzers break and stick on making the alarm sound.

[ultimate]

This is EXACTLY what i am looking for since a few weeks...

 

Please give more details about that analog-CAN converter box!

 

I need do have displayed:

- RPM up to 8000

- speed

- fuel tank

- engine coolant temp

- Lambda (comes from wideband controller als 0-5V signal)

- oil pressure (VDO sensor)

- oil temp (VDO sensor)

- boost (0-5V signal)

 

 

not a need but would be cool to display:

- Exhaust gas temperature

- amount of injected water (comes from the controller als 0-1V signal)

- gearbox-temp (2nd oil temp sensor)

 

You can put me on the list if you can display this things and the price is that 600 GBP.
