52mm Gauges

[c240yaz]

Back in the late 70s, early 80s, I was always fitting 52mm gauges to my cars, from Avenger Tigers, 2.8 Capris, to RS 1600i Escorts.

I still have various old guages and mount boxes in the garage, but most are non applicable now.

However, oil temp gauge has always been of interest to me. How would I connect this to a 2.6 V6 ? (electrical) and a Vacuum Gauge.

Also, looking at this website, some good items on the market now. What would the Lambda gauge tell you, and where would you connect it on the engine ? (3rd gauge is Engine (exhaust) gas Temp)................Any advice appreciated

Here's the wording for the Lambda gauge:

Wide-band Air-Fuel (Lambda) GaugeThis is the ultimate tuning aid! Dual digital and radial LED displays provide accurate real-time readout of either air/fuel ratio or lambda (user-selectable). A 0-4Volt analogue output can be connected to a data-logger or to an ECU to provide real-time closed-loop feedback for improved mapping. Supplied complete with wiring harness and includes Bosch sensor.

Vacuum's simple enough really, loads of places to hook up the sensor.

Oil again if you where to use the drain plug or something its simple depending on the type of sensor used, its length and the layout of the sump (not always enough clearance inside to allow the sensor to be fully inserted.

You wont really be able to use the cars existing sensors for this, not that thats a real problem.

I have a setup on my car that monitors the engine oil temp and pressure, tranny oil temp, engine coolant temp and the tranny coolant temp.

Very handy to have.

Dans, Please tell me more about your set up. This really interests me. And what gauges do you have and where have you fitted them. Any pics ?

Lambda sensor gauge looks really interesting

The biggest snag here is that you cannot drill and tap into the oil ways without dismantling owing to the swarf generated. I tried to have a look on the block, but too hard to see, any hole for an oil cooler would do.

I got curious about this setup. Is this not using the sensors on the car like you say for c240yaz?

I've seen a set-up where a Bluetooth device was connected to the OBD-II connector and was sending CAN data over the BT connection to a cell phone where an application was showing all the data in graphics. Unlikely something one would use to follow actively while driving but could be convenient for a snapshot. Of course would not work on an older car without the necessary sensors built in and without access to the data from the CAN-bus.

But is all of this data on the CAN BUS in the first place, if the info is not going in you cant take it out

All of this info is available from OBDII - though obviously you're getting into the realms of mimmicking the STAR system to read it all.

It's gauge by the way, not guage .

Spellin corrected, thanks.

TV, No intention of drilling. What about a "T" piece. Do you think this is possible ?

You always have the option of using OBD the ECU has all the info the sensors mentioned but you will only get A/F and possibly vacuum unless you used specialized software, the thing is they are not designed to be used as data loggers and the refresh rate is painfully slow.

My setup uses its own sensors to give me a view of the cars overall health if i need more detailed information i plug in the DAS, the reason i said avoid using the cars sensors is most have inbuilt circuitry the oil sensor for instance is reading 3 parameters and relaying that back via PWM.

The displays for my setup are located in little cubby thats present above the COMAND in the R171, tranny coolant temp is totally aftermarket because the transmission does not have a water coolant loop from the factory but apart from that i was able to install without too much hassle i did have the engine and tranny in pieces at the time mind you so i had a little bit of an advantage.

I have some pics of the displays before i added the oil press sensor so i will go find them and i will get some pics of the engine oil and tranny oil temp sensors as best i can because they are buried under insulating wrap.

Spellin corrected, thanks.

Title corrected.

That's one of things that I like about the old 190E 16v models, they come as standard with gauges for oil temperature, voltage, a lap timer(!), as well as the oil pressure and coolant temperature.

Oil temperature is much more useful for determining when the engine has properly warmed up, it's a shame more cars don't have this.
