Default STRI DSD - is my oil temp gauge crazy???

Hi,
I've got 4 STRI DSD 52mm gauges: Boost, Oil Temp, Oil Press and EGT. I got them from a vendor on here, who shall remain nameless....for now.

Anyway, I purchased and installed my Boost gauge first. Did some data logging runs to verify that it was reading correctly. All is good.

Next I got the other 3, installed them (both oils are in a Greddy oil filter sandwich plate) and the EGT probe is 2" below the cylinder head exhaust port of cylinder 4.


Everything worked fine. No blinking needle (wiring short detector feature) and all were reading. I verified on LGT.com against other Legacys.

But then, the EGT started reading at 400 F during idle....that's wierd I thought...it used to sit at 750 to 800....maybe swing down to 650-700. I'd romp on the throttle and be WOT and the thing would maybe go up to 600. I got a hold of the vendor and they got in contact with STRI USA. They had me send in the gauge. So I was without gauge (why they couldn't send a replacement so I don't do without, since it is under warranty is beyond me)

I got it back and it is working fine. But just after that got installed again, Oil temp started going all fritzy. The white backlit numbers stopped lighting up. The other 3 gauges were tapped into the same location and they didn't lose lighting. But the gauge is still reading the oil temps just fine. So I contacted the vendor. He said the same thing, send it in.

I get in the 2nd Oil Temp and it's working good....for a week. Back to losing the back lighting and the others are still lit. Normal function would be hovering between 170 F - 200 F. And now, it has started sweeping up and down the gauge between 140 and 180 as if it were a tach with each throttle stab....so it would occur during off throttle/clutch in and on throttle/clutch out instances.

Contacted vendor again, and he went to STRI. This time they sent me another Oil Temp gauge so I wouldn't be without.

Everything has been going pretty good (minus 1 or 2 occasions of flaky EGT readings around 4-600.....highly unlikely since the car was performing just fine) except now the Oil Temp is sweeping up and down the gauge between 140 and 180....WTH!?!??!

And the vendor has stopped conversing with me. And quite frankly, I'm tired of swapping gauges in and out and having to "prove" that it's not the install.

I spliced into the vehicle's grounding system, got the wiring diagrams for the 07 B and spliced into proper illumination, ignition and 12V source as well.

I'm about to replace the sensors on the EGT and oil temp to see if that does anything too. But a "bad" oil temp sensor wouldn't explain the backlighting going out in the gauge....so that has to be gauge quality.


I love the look of the STRI gauges and the peak recall and warning setting ability....auto calibration...blah blah....love it for all their features and the price, being MUCH less than DEFI...


Anyone with STRI DSD gauges experience something along the same lines???

Check the power connecters that you string them together for the lighting problem. I had a pin back out on mine so it killed 2 of the gauges. Than I found it with a test light on the unused connector. As for the other problems IDK.

My oil pressure actually just started going fritzy on me like an hour ago. it reads about 120 psi regaurdless if its running or not. I know the sensor and the line is good so it has to be something with the gauge itself. Maybe to many times plugging in and out while I was trouble shooting my lighting problem.

Probably going to dick with it more tomorrow but I'll let you know what I find.

If you don't mind, can you please post picture of wirings? I want to see how power is supplied to 3 gauges.

Ummm well I'd have to rip apart my dash again, but the best way to explain it would be like this...

If you have every worked on a home pc and were running some fans in your computer case ( ie 120mm or some other ) they generally have a male and female connector on them. This is so that you can take the power supply connector from the psu and hook it up to a fan, and if you need to run more fans than you hook up to the extra connector thats on the existing fan. Now the Stri gauges work the same way. This makes it easy to expand with out having something like a defi controller, and not having to tap into multiple places.

Oh... STRI gauges come with connectors that allow you to connect 3 gauges together without having to splice wires? I was planning to use 3M quick connects when my gauges arrive tomorrow.

Yes, all you have to is splice into 4 wires for one connector than string the rest off of the first one.

It's otherwise known as daisy-chaining the wiring. 4 initial wire splices are needed...then, you can daisy chain additional gauges onto the initial gauge. Another reason I got STRI!



....another reason I got the STRI-DSD line.

Found out that there is no daisy chaining on Xline gauges today...

A few months ago STRI DSD-CS no longer show the rate of information. Only Pointer Flashing. I have a complaint, and was replaced with a new one. However, after mounting a new, still does not display the information about the pressure, only the pointer flashes on the display. I checked all the wires, no it is not cleaved and cut. All wire between gauge and sensor are OK. I checked by means of wires multimeter.
I ask you for help in solving this problem. What's wrong?

cris_pl, I have had the same issue with the Oil Temp during FREEZING temps. When I first start the car, the gauge will light up like normal. After 5-10 seconds, the numbers "turn off" and the red needle will start flashing. After 30 or more seconds, the needle will stop flashing and will just be illuminated.

As I drive the car and it warms up, the gauge will read the oil temp normally, but the numbers will still be UNilluminated.

All this occurs and nothing has changed from a couple weeks before when it was not freezing outside.

Now it is spring/summer and the gauge works as advertised and like it was designed to; like nothing happened.


Here is the kick in the pants: During the same freezing temps, after it does it's flashy thing and the needle stays lit...before I drive anywhere and I turn the car off and turn it back on immediately, the gauge will light up and work as functioned, no matter how cold outside.

I spoke with RavSpec (who I bought the gauges from) and the US Distributor out in California for STRI and I'm now on my 3rd Oil Temp gauge, and 2nd EGT gauge.

EGT gauge is working fine, but the Oil Temp gauge is STILL doing it's funky "lights on/lights off" show during freezing temps. I'm unamused at this flukey design....but otherwise love the gauges.

I have yet to see a great working, readable gauge at a decent price that matches the OEM look and function.

Defi is NOT a decent price. Nope, it isn't. You get what you pay for, yes, but there is a such thing as overpaying and being foolish.

Hope that helps Cris_pl.

Damn, I was considering buying the DSD rather than the X-Line, sounds like it's not worth the money!

Alright, let me clarify. I happen to like the STRI DSD line. I think there are some flukes in the batches, but mine are pretty accurate once I got some good ones. Sensors, gauges, wiring all look and feel up to spec.

litowrx, I'm not sure who you bought them from, but I got mine from RavSpec out of NYC, NY and I don't like them. I bought a lip spoiler for my Legacy and went through 2 painted versions and finally just had them send me an unpainted spoiler and re-did the fiberglass shaping myself. But it was still the lowest grade fiberglass they started off with that has led to warping of the wing after a couple of seasons on the car.

Now, when it came to Customer Service on the gauges, at first they were responsive, but after several gauge transactions, STRI-USA (out of California) just stopped giving decent customer service and not willing to pay for shipping UNDER WARRANTY.

And RavSpec stopped talking to me altogether.

Mine work now and have for the past year, but if they fritz on me again, I think I have no choice but go Defi. I hate that option cause they're MUCH more than STRI. If STRI just had better customer service to help SOLVE problems, well, I'd stick with STRI.


CF: I love STRI when they work. I got a couple of flukes, but they're working now.

alright, now that I've written all that....my EGT gauge has gone ballistic. It's basically going from 400* to 2000* while the car is running, back and forth all while the car is performing just fine.

we'll see how STRI-USA's customer service is these days.
