Fitting Charge Pressure Guage kit to KAD42

There is no way anybody in my crew is going to be able to stand in my engine bay to take these tests so after the expense of doing it I may as well make it a permanent fixture

true, but you could buy the adapters (cannot imagine spending more than 10quid on them!) 10m of what 5-6mm vacum hose, a 3way valve and an el cheapo analogue boost gauge, or get a WIKA for another 20quid. You route the pipes to a suitable locker next to your helm, and when you want to test things bring it up get one of the crew to hold the gauge and you do the testing...
No senders, no wiring, no holes in the dash. Obviously you don't unplug any of these pipes else some of the boost will escape through that but you'll hear it :D
TBH, it's boring to just look at them gauges stuck somewhere be it zero or 2bar, no serious variations (at least in my case) nothing! It's a great debug tool though.

I bought the bloody things already. Not make me feel worse about it. I feel like a bluearsed fly chasing my tail on this one and all I ever asked was can the SC's be muffled and here we are. Faffing with turbo's. It's not like the rest of my boat isn't in a zillion pieces with all the other projects going on. :disgust: :ambivalence: :confused:
 
Well this will make you really sick....had a genius idea.

Fit the m18 to 1/8npt adapter.

Get 2 x 1/8npt tyre valves (brass....£1.79)

Get Bluetooth tyre pressure monitor sensors and stick them on the tyre valves.

If the sensors can handle life on a wheel, I’m sure they’ll be ok sat on an engine!

No wiring, can use an app or solar powered supply display or wire in a small display. Total cost under £50.

Gonna give it a go anyway!
 
Thanks Paul. I feel immensely better now. I only forked out 200 thinking bargain after seeing Volvo prices. Ah well, I'll have forgotten this time next month. I still got a bargain though, relatively speaking :encouragement:
 
Don't the tyre pressure monitors need the the rotation of the wheel to activate them? Ie they only start transmitting when they detect some rotation.

Maybe a vibrating engine will also activate them?

Bugger.....You could well be right there.

It was all going so well!

I know the feeling Boet. However in one of the diagrams they show a 90 degree valve so it seems the centrifugal switch in the sensor can work in that direction too. Hopefully the engine vibration will be enough to rattle it about enough to get a reading :p
 
:D :D :D You've been taking lessons I see.

Funny man that Roy. I wouldn't take him seriously. He's still bitter after buying a new boat only to discover that I can still out run him even when on just 3 of 4 props. ;)

See if you can spot Roy?

guys from the ebay ad:

Sensor Battery life: about 1-2 years

so I think you should be ok
 
I will let you know! If it works, I’ll market it to the forum :)

Might be a few weeks....coming from China.
 
So, the kit arrived today and I have been having a limited play this afternoon. It seems that when the sensor is detecting changes in pressure or temperature, then it stays on and communicates with the screen. But if left for 3 minutes or so without change then the sensor seems to go to sleep. It needs to be tilted 90 degrees to wake it up and then it sends an update to the screen. The screen display also goes to sleep, but vibration keeps it on. Obviously I have not tested it on the boat, but I doubt it will give an 'always on' reading when underway if the sensor is fixed directly to the engine. A solution could be to add a rubber valve extension and use a cable tie to fix mid-tube so the sensor is encouraged to be swinging around. Farsco, looking forward to hearing your report on it too when it arrives!

Thanks for the update.

I certainly will! Maybe the change in boost pressure that you must get by a few psi even when cruising will keep it awake? You can get some “stationary” tpms systems that stay on all the time but they are a few hundred quid. I was wondering if the sensor could be modified to stay on all the time. We shall see!

Another option is this http://www.transducersdirect.com/pr...re-transducers/wireless-pressure-transducers/

Again, not that cheap and needs an app. I don’t think you can see 2 sensors at the same time with those either.
