Todd,
I've sent you a PM earlier, I'm not sure if you're able to receive those looking at your amount of posts.
I'll send a PM again.

Code:

const int RELAY_PIN = 3;
in Setup, add the following code:

Code:

pinMode(RELAY_PIN, OUTPUT);
in the loop, add the following:

Code:

if (rpm > 2500 && rpm =< 4000)
{
digitalWrite(RELAY_PIN, HIGH);
}
else
{
digitalWrite(RELAY_PIN, LOW);
}




many thanks for this - quick question does this need to be connected through the obd2 port or can I get directly on the can line? My obd is on use logging to the lpg ecu when running on gas you see.

also great code snippets - ideally I’d like to use a non latching rgb led button that defaults to green and the code you recommended - but if I push it I’d like it to go blue and give power at all revs, but if I press again it goes red and takes power away at all revs… guessing this is doable too?

My car also runs on LPG (Prins VSi), but the OBD port is not occupied.
Directly connecting to the CAN may be possible but I have no experience with that.
Others used an analog signal from the engine but I don't know if this is available on our cars.

Using a pushbutton and an RGB led is also not that hard,
RGB led can be an analog one where every colour has one pin occupied on the micro controller,
or a digital one with one or two pins connected (WS2812B or WS2813) and using the FastLED library.

i had seen that project with the coil wire I just want sure how to specify an rpm range but hopefully I can use that example code in there.

i May pick your brain when I do this at some point in the next couple of weeks or I’ll report back!

i do have another rather odd problem you may be able to assist with… this actually isn’t a Jaguar it’s an l322 4.2 supercharged Range Rover (so same engine electronics etc) the entertainment system does a while back so I gutted it and modernised it - great… the only problem is the cluster time and date is wrong and it cannot be changed as the old headunit handled this - any idea how to set this via canbus?

thanks!

Perhaps it's in this thread but I've not seen it, most of us know what 'safe' voltage and coolant temp measurements are but what about the others?

So for both 4.2 and 5.0

AIT 1 & 2?
Transmission temps?
Oil level inches
Oil temp
Gallons of oil
Gearbox temp

If I'm being blind if someone could point me to the post number in this thread :D

I’m only now getting around to assembling and installing cabrioBob’s AUD.

It needs to be flashed to 4.2 (is currently set to 5.0)…how?

I need to grab a cable, plug one end into aud and other into usb port on desktop.

Then?

I downloaded ez 4.2 but then what?

Hello Wym,

download this pdf:
https://x150.bobhome.nl/download.php..._EZ_update.pdf

it shows the update instructions.

thank you Bob,
the reflash went well and everything works...for some reason my cig lighter socket it dead, sure hope it's a fuse.
thanks again, you did an outstanding job with this!

wymjym 06-11-2022 05:10 PM

just a blown fuse, now all is good.
a quick question, is the obd socket always live or rather does the vgate draw current 24/7?

You really really should know the answer to this. :D

Ask yourself this simple question, when you/anyone else has run a scan on your car will it scan when i's off/not in aux power?

Nope as there is no power to OBD....so yes it switches off :)

thanks, Jaguar does so many things in a unique manner that I wanted to confirms that the Elm unit didn't keep the port active since It is broadcasting bt constantly.

Well, The vgate power light is shining red after shut down, locking the auto and 30 minutes time...so I guess my question should be, is this normal and is the draw significant given the somewhat delicate electrical system?

wymjym 06-14-2022 04:16 PM

I’m having a little issue with my AUD.

The AUD finds the VGate 1 out of 4 times at start up. If it does not find it immediately it almost never will find it unless I remove the VGate and reinstall it (VGate).

Suggestions are appreciated.

Sorry for the late response.
The Vgate should go into sleep mode minimizing current draw after some time when the car is off. Red led should then be off.

Mine does this occasionally when it is close to freezing.
Turn the device off when you leave the car, and after you started the car wait 10 - 20 seconds before you turn it on (Vgate should be plugged in already).
Also be sure no other device is trying to communicate with the Vgate.

wymjym 06-15-2022 11:14 AM

I'll keep an eye on it, maybe a faulty Vgate. As to freezing, I wish! Yesterday's temps were 103 (f).

Mine connects reliably on first start up of the day, or if the car has been off for a couple of hours. But it won't connect if I've had the car off for just a few minutes, like the time it might take to go into a store and come back out. (I always lock the car with the fob when I leave it, even in the garage, to shut down the computers, but locking the car with the fob or not has no effect on the re-connection). In the case of a failed connection I have to unplug the vgate and plug it back in, which always brings it back. I assume it is a bluetooth thing and it it predictable enough that I just deal with it that way.

Since no one has chimed in with similar symptoms, sounds like a defective V-gate. You might consider ordering a new one.

Hi,
Should have got one of these when I could! I am now having both battery & temp issues and would love to have one.
Does any one have a kit they have not installed and are willing to sell?
Or just the PCB? I have approached Bob and he has none available.

Thanks
Geoff

Yes Geoff, I have an uninstalled kit and have just sole my XKR so its no longer needed - you'll need the 3D printed housing though, which I didn't get made. I'm in the UK. Make me an offer!
