Show me your boost gauges!

[lukemk5gti]

Anybody out there able to recommend a boost gauge they've fitted to their GTI?

[MC71]

Newsouth indigo. Had mine for years and was great (had mine in vent pod). Lights up OEM in colour at nighttime plus helps to see if there are any boost related problems at a glance.

Defi Boost gauge if you want to spend more and P3 if your after a digital one.

Awesome GTI sell Newsouth.

Is the boost readout on Polar FIS adequate for keeping an eye on things?

Or would a proper needle be better?

Have the new south indigo for boost and polar FIS for temps etc.

Nice. Can't deny a proper boost gauge is a cool thing anyway :)

From what I've hear the boost on Polar is requested and not actual as there's no factory sensor but I could be talking sh*t.

That'd make sense, as normal gauges use a boost tap rather than an existing sensor. Although you can log requested against actual in VCDS can't you... so I'm not sure? I may also be talking dogsheet :)

check out PSI tuning website they have several OEM looking options available.

Wouldn't the ECU work out boost pressure using the manifold air pressure (MAP) sensor? That would be a way of the PolarFIS being able to display both requested and "actual" (as a calculation of ambient air pressure taken from MAP reading). Just a guess though...

[horsemeat]

Polar fis apparently displays both "actual" and "requested" parameters. I've no idea how it's accomplished. Seems to peak at around 11 on my stock k03 which is about right iirc.

The readout isn't very smooth, a dedicated gauge would be nicer for sure. I like dubvrs' setup.

Think I'll go with the P3 down the line. I missed out on one for sale here but I'm sure I'll pick one up!

[strothow]

I had one on mine when i bought it, don't want it, welcome to it if you want?

Its a complete replacement to the vent.

Not sure on the petrol ECU's but there is one limitation with Polar FIS, well it actually lies within the ECU when it comes to boost. It does with the Siemens ECU anyway. It is able to read figures higher than 1.6 Bar but cannot display them. If you log boost in VCDS, it will go off the chart at 2.6 bar (1 Bar atmosphere + 1.6 Bar boost). This also happens on the Polar. Mine maxes out at 1.66 Bar. My map is set to peak at 1.75 which I cannot see without a mechanical gauge.

Here is my gauge. Also Newsouth Indigo.

Will be getting a new south vent gauge shortly.

Looks like a proper little cockpick that pic!

Iv got a p3cars in my car but for some reason it slowly drains my battery, probably doesn't help I only use the car once a week
It is a great bit of kit tho im assuming that because my car is an 05 has something to do with the drain
