Fitting Charge Pressure Guage kit to KAD42

OK, in that sense, they will be fine!
Good to see if all the work paid off and if everything works as it should!
Then keep track of pressures at certain revs, remove the gauges, get a blank there and you're fine.
Or get the 4quid valve in and hope it works :p

FWIW, I've had my port turbo rebuilt (not excellently, but cheaply) now on full boost, stbrd engine does 2bar, port 1.8 maybe 1.85 on a good day... Don't know how many ponies I've lost, but it's there to tell me that I should really have another turbo there (which I wont!)

cheers

Can any electrical guru help me out here. My VDO gauges arrived and they need a Molex 334720801 connector. Great, an obsolete connector type but I managed to find some on American Fleabay.
I have no idea on how to wire the connector up. I am a purely analogue system. Which is positive, negative and signal wire(s). All my other guages only have these three and separate additional for dash light.

This is the only instruction on wiring:

This is the sender unit:

not sure, I'd personally just cut the molex off, strip cables and figure out what's going on...
The CAN-L on the gauge literature confuses me, you sure you got the right gauge?
Also check what's the model # of the VDO sender. Check if it's for a dual station or not.
If not, the two terminals go straight to the gauge.
If it's a dual (and unless I'm badly mistaken) you have to get the one terminal to the gauge, the other is just ground from the engine.

OK, will work but you'll need to play with it a bit...

The sender is okay, it says insulated, so yes, two cables from the sender to the gauge.

the gauge is both analogue 10-184Ohm and CANbus, forget the canbus, just need to find which cable does the analogue trick :D
third cable to the gauge is the 12V +

Just fool around you'll get it at the end. I'd say, skip the CAN-L and you have 3 cables to sort, easy...


well, just googled a bit and seems that:

terminal30 is V+
terminal31 is V-
terminal15 is V from ignition (defies the whole point as mostlikely 30 is also from ignition...)
sensor input is the one from the sender
the other from the sender goes to ground (or back to 31 to avoid interferences??)

If any proper electrics specialist says elsehow, believe him not me! I'm an architect after all...

cheers

Thanks Vas. Much appreciated. I was worried I might blow the thing by putting current through terminal posts that shouldn't be getting it.
 
Or buy a tpms system and have none or these problems :):):)

......and no doubt have other ones but when my valves arrive from china I will let you know :D

Yes. It seems there is a penalty for being a un-"hip" luddite after all. Forum to my rescue :encouragement: , yours may prove more difficult for them though. I wait to see the outcome. Best of luck :)
 
Big news.......the 1/8npt tyre valves arrived from China today!

I will fit everything this afternoon with a few pictures to follow. Doubt I’ll get to use in anger for a few weeks though to see how they work :(
 
Fitting was easy.

I think the valves are in constant connection with the display. Over the last few weeks, the temperature aspect has changed each time I’ve gone down to the boat. If so, that’s great!

Started up on the dock and brought in the superchargers, both changed but it is a little delayed. Main thing is....it did change the pressure reading! I will have a go in anger as soon as weather, work and tides allow.

The display is nice and unobtrusive too.

Outstanding! What a simple and cost effective solution. Think I will be following your lead.

Do you have a link for that exact TPMS?

Great work.

Post robust testing of course! I am optimistic. I read that they can be checked while a vehicle is stationary so cant see why they wouldn't work.

Is anyone familiar with the volvo penta d series, or more specifically the d4, is there an existing tapping to screw one of these sensors into?

If so, roughly where is it and what thread is it?

I quite fancy giving this a go myself, but not if I have to drill the inlet manifold.
 
Superb Farsco
Just to make sure I get the right fitting can you provide a link to the adaptors you bought. I’ve got KAD43’s so the same
