Fitting Charge Pressure Guage kit to KAD42

[Mr Googler]

Yup....gets up a little quicker...not that it was slow before. J series props came with the boat and they have good hole shot so probably masked the issue.

Can’t tell if cruise rpms have dropped as there were some big holes out there today :encouragement:

I think you have found a great solution to identifying boost issues on KADs, great stuff and thanks for posting all the relevant info on the parts. Much easier than trying to find a volvo tech with a VODIA box. Fingers crossed for a great summer.
Now if anyone happens to know where I can find a similar solution for engine temp measurement that would really useful on my flybridge

 

[Mr Googler]

Do you want the coolant temp? Are your engines edc?

 

[kashurst]

yes please

 

[Mr Googler]

Sorry...I edited....are you kad300 edc?

Sorry...I edited....are you kad300 edc?

not good with Volvos (er, have no clue!) but I do remember a piece of kit that would fit some engines and give out NMEA2000 of the engine data, or am I dreaming?
Some ppl here bought it, tested it and it worked.

PS. well done FARSCO, probably wont see any drop in revs in cruising, maybe half a knot more on wot or something

yes kamd 300s, in a flybridge so trying to minimise wire runs (I'm getting lazy). I keep thinking about getting a pair of JDxxx interfaces to plug into the KAMDs then plug into an NMEA 2K bus etc but then need a new plotter etc etc. All I really want to know is the temps at the fly helm.

hm, beat me to it

you don't necessarily need a new plotter, get a cheap multidisplay thing that's N2K and be done with lots of info on the engines, plus warnings.
Still need to route a N2K backbone cable up on the f/b, but that's just one, will do display, with a tee a new plotter if you get one, etc.

 

[Mr Googler]

Yeah that’s where I was going https://www.yachtd.com/news/j1708_kad_and_practical_boat_owner.html

How about a wireless camera pointed at your gauges at the lower helm....iPhone or iPad upstairs? Cheap but not very sexy.

You can get wireless / Bluetooth temp sensors but not often in pairs and you’d need to make a hole in the coolant circuit somewhere. Tricky one

 

[kashurst]

where do I get NMEA 2K display thingy?

 

[kashurst]

the KAD/KAMD thermostat housing has two ports for sensors. On the KAD 300 only one is used, that's for the helm gauge. The EDC temp sensor is in the exhaust manifold near the turbo. So pretty easy to stick another sensor in thermostat box.

thought about camera etc but it's too sunny in the summer and you cant see anything on ipads/phones etc (yes I know, no sympathy)

anywhere

Garmin GMI10-20
Maretron DSM150-200-250
Simrad
plus the cheaper Axiom series kit which is brilliant and reasonably priced (relatively iirc)

I'm becoming a bit of a datacholic and I've managed to have even more data on the N2K bus than on the lower helm dash
down to EGT, g/box oil pressure & temp, seawater pressure, boost, coolant temp, etc

DSM250 looks like this (ignore the -127C, still testing and not all sensors connected, plus port engine is in bits as I'm servicing heat exchangers and drilling for the pyrometer sensor):

mind, Garmin GMI10 is similar, graphics are better in the Garmin (and it's way cheaper...)

cheers

Thought I had it sussed but it’s discontinued.

https://www.plxdevices.net/product/...luid-Temp-with-2-sensors-(1/8-NPT--300F/150C)

They still do a larger module but then you have to add temp sensors and a wireless link.....the n2k converters will probably end up a better option

at that price (and if it was selling which I doubt) I should probably do a career move and start selling sensor -> N2K boxes...

You should! Vas Blackbox Solutions ltd :encouragement:

yeah yeah, the problem is that I've managed todate to only work and get paid doing what I really like, so work is fun.
If I have to do that for a living, it wont be fun, teaching and dealing with 20yo is always refreshing, so black box building is going to remain a hobby...

So, all the bits for me to add a boost gauge have now arrived, and I'm off to the boat next weekend, so I'll have a go at fitting it all then, but in the meantime does anyone know what the specifications are for the correct boost on a vp d4 260?

Ive no reason to think I have a boost problem but it would be nice to see if the figures from my engine match up to the specifications.

K....after much searching....I have an idea. BBQ meat probs

ThermoPro TP20 Wireless Remote Digital Meat Thermometer with Dual Probe for Smoker Grill... https://www.amazon.co.uk/dp/B01GE77QT0/ref=cm_sw_r_sms_tai_xMFSCb...

Obviously the wrong probes but if we can figure out the probe resistance and wire a couple of plugs on which go into the transmitter.....bingo!

 

[kashurst]

brilliant!
thanks for finding those - for £45 I will get a set just to see what they are like. Worst case my BBQing will improve.

not going back to the boat until summer now so will be a while before I report back on their usefulness.

I would imagine they are 2 wire sensors as the plugs look like standard jacks. The temp range is 0-300c so we need to find a 2 wire sensor that will work. I certainly know little or nothing about temp sensors but having had another quick google..

Which wire is + and - ....no idea.

Bit of trail and error but at least you can compare the proper probe with the kit to a different suitable probe at the same time on the same heat source.

Hoping someone on the forum is a temp sensor expert and can direct us to what type the original probes are likely to be and what we could substitute to make them work on engines.

I’m also going to do a live chat with ThermoPro to see if they will tell me what their probe specs are....long shot I know but cant imagine it’s a huge secret in the meat probing industry!

I feel another patent coming on
