I'm interested in the same thing and so far everyone has told me its a no go.

 

booooo lol
well maybe ill be the guinnea pig

 

I have a mate who's good with electronics. I asked him to develop a small digital EGT (3 digit diplay) gauge for me. I don't have PDC, so I'm going to fit it in the switch blank on the dash where the heated seat switch and passenger airbag warning light goes. I'm going to have two made, one for the TDI Jetta as well.

You could have something made up that uses the same display to switch between boost and EGT with the press of a button, that fits in the same space. I think a red LED display would probably look the closest to OE.

 

Do they even make an A pillar gauge pod for the Touareg? That would obviously be the easiest. Then just find some gauges that match.

Not sure you would want to put a pod there anyhow since I believe there is an airbag in that pillar. There probably is no pods made for the Treg given that there is no demand for them. You may have to just buy one and mod it for your needs.

 

LOL at the above!

DO NOT put gauges on the airbag pillar, my freind got seriously injured when he put gauges on his jetta in that spot and then got into a wreck. They were pulling plastic out of his for 2 hours!

I say a nice 3 gauge setup on the dash where the cubbies are. Kinda like an FJ...

Question- Boost gauge on a V10? What you want is a vaccum gauge. And I would go with CHT vs. EGT. EGT is meant to tell you whether you are running rich V lean. The computer does that for you. Great on carburator applications, on Fuel injection, all your doing is verifying that the computer works. While a CHT will tell you wether or not you are about to blow a head gasket. That is the info you need. Do the CHT's that are thermo rings that install with your spark plugs. Nice clean install...

In case your wondering, I am an aircraft mechanic and aircraft engineer. I do this kinda stuff for a living and hobby.

 

Within the context of "tuning," I would get a data logger before buying a gauge of any kind.

That CHT idea is interesting.

To kind of add to the above, and how an EGT gauge is not necessarily needed on this application, doesn't the V10 already have a thermocouple located somewhere within the vicinity of the exhaust manifold(s) and where the turbo(s) bolt on? If that's the case, and I'd be very surprised if it wasn't, seeing that my own Passat TDI has one, wouldn't Vag-Com be able to take that reading???

For automobile applications, although this pertains more to gassers, the usability of the EGT really comes into play when adjusting the ignition advance. This will let you know if your adjustments are within the given safety parameters.

Generally Speaking:
More advance = lower temp,
Less advance(more retard) = higher temp


I think that anybody here who is planning on chipping his V10, needs a boost gauge to monitor any boost spikes, but then again, any split second spikes would be missed by the eye, hence logging. Nevertheless, the responsible pilot should have at LEAST something on his tuned vehicle. I say the more, the better!

Here is some food for thought. What about an exhaust back pressure gauge? This is good for monitoring any changes on the exhaust side as well as any other problems within. A boost leak will immediately turn up as higher exhaust back pressure as an example. It can also be used to monitor pressure losses through the intercooler while on boost.

 

Correction- Sorry I forgot the V10's are twin turbos...

YES to the boost gauge and if you have a diesel get strictly a BOOST gague! Diesels do not operate under vaccum conditions.

as far as the existing thermocouple....I don't know. I would be skeptical as far as what they install from factory. what they install may be a GO/NO-GO sensor. Hit a temp, shuts the truck down.

Check out TMTUNING.com they have these cool new displays called Liquid. Here is what it is monitoring:

liquid by Race Diagnostics The liquid is a multifunction gauge & diagnostics tool which can display many types of information related to your car´s performance. It displays data in a traditional gauge format as well as a scrolling graph allowing data history to be seen visually.

The liquid currently comes in two hardware formats: round and rectangular.

The liquidTT is a round format, which is designed to fit perfectly inside the OEM vent from the MK1 TT (Model Years 1999-2006).

The other liquid format is a rectangular printed circuit board (rather than the round board used in the liquidTT). This unit uses the exact same hardware components as the round unit, but the printed circuit board is reduced in size to the minimum possible. This allows the rectangular format liquid to be installed in locations that are much smaller than the original design - Get Creative!

The mounting tabs and the "joystick" on the edges of the PCB can be removed individually. The minimum size possible for the board (with all tabs removed) is 39 mm x 57 mm - this is the same as the physical package of the LCD display itself.



and the price is Great, I think its 300-400 done. Monitors off your ODB2 port.

I agree, if you tune, you cannot know enough info.

EDIT: now that I remember that you have a Twin Turbo- the EGT gauge is useful to monitor your turbos. Now people run them to monitor to ensure that there Turbine temp stays within "Good" range. The EGT actually doese not monitor your mixtures, but instead monitors your turbos to ensure that they stay within operating temps and when they hit that redline, you can see it and back off the boost to cool them down.
IMO- EGT/CHT and Boost are are requirement for chipped vehicles AT MINIMUM!

I've seen a video of this thing in action on a Audi site somewhere while doing google searches for boost gauges. It looks pretty sweet and seems like the best all in one package out there. Too bad they don't have one for the V10.

Would one of the other VW diesels work for the V10? Wouldn't think so but does anyone want to buy one and let us know?

 

Wouldn't the computer just store any values that are out of range as an error? You could just do a vag com scan and see them...I would assume any values out of range would also trip a CEL letting you know to scan your logs.

If you want it that's cool, I'm just trying to understand the value of a real time display given that the V10 far exceeds the towing capacity of the chassis (ie: 7700lbs isn't exactly taxing the engine in any way).

 

I know for a fact, that guys like Jeff (Rocketchip), won't tune your TDI to anything higher than Stage 2, UNLESS you show responsibility as a user, and install at the very least a boost gauge and sometimes he'll even request a larger intercooler to start the process. But we are talking about getting into some more significant numbers here. I don't think that a Stock V10 TDI or even one mildly tuned "conservatively" with a Stage 1 really warrants any of this IMHO, other than an extra gauge with matching night lighting as a cool factor. Still nice to have one no doubt(boost gauge), as it can be used to monitor on the fly as the years roll on your Egg, and you get a good "feel" of what vacuum reading your engine should be displaying when you first fire it up every morning.

Consistent numbers are always a good thing. Once they start to even slightly deviate over time, or even more one day, you can get ahead of the game and solve the problem before the parameters are ever exceeded, and real drivability issues start to be noticed.

 

Can someone hook up a VAG-COM to their V10 and see what protocol it uses?

The Liquid gauge that is referenced earlier in this post says it will work on any car using protocol KW1281 or KWP2089.

 

Well I checked it out on my 08 V10 and the engine protocol is KWP2000. So I guess the Liquid gauge will not work for us.

If someone wants to give it a shot anyway please do and let us know.

 

As for the Liquid gauge I contacted them to see if the KWP2000 would work. Here is the reply

Hi.
KWP2000 is a generic protocol, VAG run a proprietary protocol over the top of this to provide block data used by the liquid and vag-com etc.
The existing product will work with your engine if you have a K-line interface on your obd2 plug. if it is CAN only on the OBD2 the you will ned our new product available in a couple of months.
Best regards
Jim

Can anyone explain this a little?

 

I don't fully understand it myself, but here's what I've surmised...

K-Line is the old protocol used in the first vehicles that had OBD2 on-board diagnostics. VW's A4 platform (Golf & Jetta(1J), New Beetle(9C), Audi TT(8N), Audi A3(8L)) were all running K-Line, for instance.

The T1 was also running K-Line (KWP-2000), but with some CAN capability as well. My understanding is that the T2 is full CANBUS, but if you say that your '08 V10 is still running KWP-2000 on the engine ECU, I might be wrong. Maybe the engine ECU was carried over from T1 to T2...?
