Default Omori EGT gauge problem (long)

Hello all,

I've had an Omori EGT gauge for nearly a year now. I bought it because I thought it would be higher quality than an Autometer.

Anyway, back in August it started malfunctioning on me. The needle would bounce all over the place or it just wouldn't work. I contacted Omori-NA and they promptly sent me a new probe. I was pleased.

That seemed to cure the problem. However at the beginning of last month I noticed the gauge would not work in damp or wet conditions. Now it's becoming a real pain. I just took a ride and it seemed to be working fine all of the sudden. I went to the carwash and washed the car( I didn't spray underneath), started it back up, and now it quit again. On the way home it started to come back alive, but would only go as high as 600 F.

I've pulled the probe out, it looks fine. I followed the wiring back to the gauge, it looks fine. The gauge has power( it lights up fine). I have the probe installed in the casting spot on the manifold between cylinders 2&4 about 5 inches from the exhaust ports.

The manifold is protected by a skid plate, however the wiring for the probe is zip-tied to the subframe and is exposed to the elements under the car until it is routed up to the hole in the firewall behind the brake pedal.

I've called Omori-NA twice in the last week and left two messages, but they haven't returned my calls. My warranty has nearly expired and I'm getting very frustrated.

Any ideas? Thanks,

Bryan

My Omori EGT gauge started intermittently working just this past weekend. It worked on the way home tonight. Didn't work yesterday. It worked Saturday at 9:45PM, shut the car off for 10 minutes, turned it back on... nothing.

My install path for the probe is identical to yours. The exhaust manifold tap is even in the same location as you.

I was under the impression that Omori-NA did not really even exist anymore. I forget where I saw that. I do know, however, that Kastle over at kastleskorner.com has not been able to get in touch with anyone for quite some time.

jblaine,

I had the same thing happen to my Omori EGT gauge. It would bounce everywhere, then sometimes work, and other times it would not work. I thought the New England cold was to blame too, but it was not.

I'd suggest you guys to check your ground wires to the gauge. I used to have all my grounds go through the clock ground. Then I rewired my grounds of all 3 of my gauges to different spots. There are 2 ground spots right behind the glove compartment, where the screw goes into the metal bar going across the front of the car...

And that fixed my erratic EGT needle. It was all a grounding issue. Also, you may find your needle to behave lower than normal for the next few days. It will slowly get better over the next few days, with the needle getting closer to normal. I contacted Omori about this and they did not have an explanation for it... Oh well, it worked for me. *shrug*

No problems with my gauges (60mm Wrx-look Mech Boost, EGT, Oil Temp).

Seems strange to me that you haven't been able to contact Omori-NA recently. I just bought the set of 60mm gauges 2 weeks ago to replace my 45mm set. I've exchnaged numerous emails with Greg at Omori-NA during the last few weeks. Try sales@omori-na.com, thats the one I used.

Well still no call from Omori-NA ,but I did get an e-mail. I finally just e-mailed the sales department, and got a reply 30 minutes ago. Here is the e-mail I recieved,

"Bryan,

We are in the process of trying to obtain replacements for a few faulty EGT probes right now and we are at the mercy of manufacturing, unfortuantely.

We are waiting for them to arrive.

So I guess I wait. At least I got a reply,

Got the same problem here- whenever it's wet out or I wash my car, my EGT gauge goes crazy. It bounces all over the place. I bought the gauge well over a year ago, but only installed it a few weeks ago.

On top of this, I had a boost sender go bad just over a year after I bought the gauges.

Not happy with Omori at all. For the money I spent on them, I would have expected a lot better. I'll be posting a review in forum.

Similar problem here. Mine used to bounce all around and get "stuck" at the high temp point when it was wet. I could jiggle the wires a little and it would work again.

Now, it no longer goes to the zero point when the car is cold. The new cold point is at like the 600 deg point. The thing is that it still works (just a little off). The distance from the zero mark to the 600 mark is the same that it is off by now.

Holy two-year-old thread!

My oil temp used to bounce. I pulled the wire and discovered that it had been rubbing on the uppipe and had melted. Bad electrical connection = bouncy gauges.

5 people out of however many with Omoris and you all worry about quality? I found two threads about issues with Defis. Are they bad too?

For the fellow with the 600 zero-point: There is a dial (under a sticker) on the back of your gauge housing that allows you to adjust the needle.

Tried it, I believe that screw adjusts the temp at which the warning light comes on. It doesn't adjust the needle at all.

On a side note, does anyone know how to take the whole assembly apart? I took the two screws off the back, but the housing didn't seperate. I just want to see if I can open it up and somehow manually turn the needle back to the zero point.
