or anything that peter has added to the dutch software iat afr etc 

I have Dutch in my test car , don't know anything about it yet If it has any data coming out of the ecu then I will see how to read it

Sadly it's all on k-line there isn't any CAN on the vx so you are a little limited on how much you can pull out of the ecru before you get misfires.... yep, back then if you read too much data it would screw the interrupts of the main software this wasn't upjust a vx/gm issue, many others did too.

 

 

i dont no if you have wideband and other things on your dutch but if you want to use mine to find it if its usable let me know

In that case just fit an analogue oil temp and pressure sensor for now , to get more data into the system it can be added to the canbus with an analogue to canbus magic box

[haggi961]

How many inputs can be added to this for standalone operation? For stuff like oil pressure, oil temp, boost ect.

Id imagine you can add as many analogue or digital inputs as you want with a CAN converter. I had to make one to get a large chunk of the evora to talk to a 12" tft dash

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.

I was considering having my test unit fitted this week but I'm at Spa on Monday so thought better of it. Next week I'm hoping to have a development unit in the car to get some time with it, so those attending the forthcoming south Wales run can have a nose. Having seen the units in the flesh they really are superb. The 8" with nav cast and a small (digital) speedo would be almost like the Audi virtual cockpit.

Yes, instead of fitting extra plugs for more analogue, I decided it would be best make an any signal to can box, much easier to install also as it only requires 2 wires into your engine bay to pickup all the data you. need .

Sorry , headlight noise is gone .

Great work looks great and you sound as though you know what you're talking about! Heck, you even got praise from slindborg!!!

I still need to recreate the original vx cluster graphic , so not all is lost You can still drive with the original look ( not the same I know) and switch Screens when needed to display other stuff But I agree it won't be everyone's cuppa tea

That's what I like about it - looks like a really great piece of kit. Sent from my iPhone using Tapatalk

Soooo, lap timer, circuit overlay, sector times, connect to a gps reciever or the new version of the race transponders?

Another thought: how does it register total mileage?

In the same way the original cluster does , takes the speed input Works out distance travelled and stores it in an eeprom . The cluster starts at zero , I can add a preset value On the update list is a function to set the mileage yourself With an encrypted record stored of the correction So this record can be viewed to verify the new cluster took the old clusters mileage Record at a certain date . The date will be taken from a GPS receiver attached to the USB

Got laptimer , beacon and gps (beta as it needs a lot of testing) No circuit overlay or sector times Does have data logging so this info can be taken from there

[Mattyboi]

This looks great! I'll be watching with anticipation as I want one really badly!

[turboluca]

Just to let everybody know Iv seen this in the flesh an OMG it's the bolocks!!!!! When I seen it last Sunday I knew the Vx boys on here would love it !! Great job hopefully see you again Alec when your down 👍🏻👍🏻

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?
