Auber instrument trouble

[SKULLYOTA]

Can anyone help me with my Auber install? I have two gauges for EGT and for boost, but my readings look way off.

I made the power input connections just fine, but my temp readings for the EGT have a (-) sign in front of them. Does that mean my EGT wiring is backwards??

My boost gauge is reading Bar maybe? I followed the setup guide and input the codes to program it into PSI but it looks off. Does it need constant battery power to not have to be reprogrammed every time?

How are the three wires for the boost sensor supposed to be wired? I have it as: Negative to terminal 6, positive to terminal 9, signal to terminal 10. PArt of the instructions says to switch 9 and 10, how is everyone elses????

@Willis I know you've done a lot of these!

Pic for kicks:

boost on the left, EGT right

well i feel stupid. I switched the leads on the EGT and it seems to work now. I also went back thru the programming steps for the boost gauge and it seems to be right on. sorry everyone!!!!!

The Aubers have a mean learning curve. Tech support is super friendly though/

So they installed the probe downstream of the manifold. Is this normal for EGT? I thought it should be on exhaust manifold.

That's the boost gauge fitting it looks like to me. And that would be a good place to see pressure, in the manifold.

Ok thanks, I didn't see another probe for temp. They are having issues with auber seeing correct temps.

You are correct, usually the EGT probe is in the exhaust manifold before the turbo. They could have put it after the turbo but that's not as good at all.

Should be a braided looking wire you can see for the EGT gauge. IF, they did use that port for the EGT and put rubber hose on it, that's 100% wrong for EGT.

Ok thanks. I don't want to tell mechs how to do their job. We'll see if it's an auber tuning issue.

That photo you posted is the Boost Pressure "probe", basically anywhere to measure boost pressure and that's a great place like FJben said.

The EGT probe should be on the Exhaust manifold BEFORE the turbo (this is a riskier install: have to drill and tap the manifold slowly cleaning the drill bit often), but it is slightly acceptable to do after the turbo, you'll just mentally have to add a few hundred degrees to the number if so.

Your the 10th or so person that voted before turbo so I'm firmly on your side. The shop knows my position on that and I have a feeling they did after turbo. I didn't have enough time to go over the motor but I'm sure they'll get it right.

what he said^^^. If a "shop" put the egt probe post-turbo, they shouldn't be called a shop. It needs to go in the manifold to actually measure the exhaust gas temps before it gets adulterated.

Thx

This is where they plumbed for EGT. Position ok?

 

[AirheadNut]

Yep, that's ok. Not perfect (ideal would be right in the neck of the manifold where the turbo bolts on) but at least it is pre-turbo and should give good readings. Lots of people use the EGR ports like that.

Great, thx. Shop was having issues with temp so I Naturally thought it was downstream.

The Auber gauges can be a little tricky to set up correctly, and can sometimes go a little nuts and have odd readings. The majority of the time they work great though.

Good to hear. That's probably why they're having issues.

Yep, I occasionally had some issues with my Auber gauges. The EGT probe, just make sure that cable has good slack and isn't being moved or tweaked by the engine/body. It will cause them to fail. I've had 2 fail and that's the only thing I can find is that unless that cable has good stress relief, it will probably fail.

Originally the kit came with a braided line but I think they wanted more length.
