Boost Gauge Install and How Factory Gauge Shows 40PSI of BOOST!

[@HumbleMechanic]

I hope you guys enjoyed this video. It was fun to clear up some of the weirdness on how that PM gauge reads. What should be the next Golf R mod?

[@luisg1653]

I would have added the "several busted plastic tabs mod" on this install. Its weight reduction in my book. Nice work!

4.0 seconds to 60 is ridiculously fast. My car would still be below 40 mph in that amount of time. Crazy performance considering how live-able they are for everyday driving.

[@P3Gauges]

Always great working with the HumbleMechanic. We're looking forward to more projects in the future!

[@hunter3899]

Absolute pressure is better when tuning the vehicle that adjusts load and fueling based on the altitude. You dont need two separate maps and sensors to determine the actual engine load that is being produced compared to the reference map for requested load. Just simplifies a variable.

[@Celician83]

Good heads up on the OBD plug. A year after I bought my car I was using a bluetooth OBD reader, keeping it plugged in all the time. By that time my factory battery was 3 years old, and just was not up to snuff. My suggestion, if your getting this and you haven't replaced the battery in a few years, may be a good idea to replace the battery as well.

[@jonasthemovie]

I love SI units for a reason.

[@alastairbutterworth3495]

Is that because you would rather be deceived in Pascals rather than psi? Atmospheric pressure and gauge pressure apply to both systems

[@alastairbutterworth3495]

Side note. I also love SI units😀

[@TheRebuilt1]

That 4.1 0-60 is sick to think about and respect to you. I'm amazed and thankful how far technology has had a positive influence in the automotive performance world. I think when i was a teenager the Lotus Esprit Turbo was the first car I remember reading about to get to 60 in 4-second range and that was the early 80's. Impressive sire.

[@1chuckice]

I bought p3 gauge and my 17 golf r is showing 3.6 seconds everytime. I have Apr stage 1 dsg tune as well, turbo inlet pipe. inlet hose and cold intake . l was doing 3.8. after I did Haldex mod I can hit 3.6 everytime

[@nhzxboi]

I.E. (Long story short), the factory gauge is an "honest" deception. It is used to awe those with an IQ in the "naive" range. Despicable but no doubt, effective. Shameless commerce as the Car Guys would have proclaimed.

[@willferland]

This is actually really interesting, in my state of Rhode Island which is pretty much at sea level, my GTI performance gauge reads up to 35 psi at full boost. When I went up to the mountains in New Hampshire that dropped to around 30psi

[@avinut]

in/Hg absolute as we use in aircraft. Idle about 10 in/Hg, ambient about 30 in/Hg and boost above, (say 60 in/Hg for example for 15 PSI boost) No confusing switching of units. (pilots aren't too smart you know)

[@moparboyz920]

I would like this kind of set up for my 2023 Volkswagen Arteon but can’t find it anywhere I ordered a $75 boost gauge off of Amazon but I guess we’ll see how it works.

[@tylerkikkert6600]

God this video was a relief. I was shitting my pants thinking my gli was pusbing 35-40 lbs of boost. Thought something was wrong 🤣

[@Brad-k]

@HumbleMechanic thanks so much for this info! I have a small BT OBDII reader with real time info to my Android (using Torque Pro App) and I was always wondering about the boost and also the atmosphere setting.. This makes total sense to me now! Nice and thank you because this was driving me nuts lol.. Keep up the great work and as always looking forward to more of your videos.

[@einfelder8262]

Looks like you forgot to remove the plastic film over the front of the gauge. Pretty cool implementation into the vent, though.

[@hellaflushhonda]

Are you able to remove to atmospheric from factory gauges so the display can be more “accurate” to what we’re used to seeing

[@TheDjAust]

FYI, that's not the coolant temperature being displayed on the MIB, It's your oil temperature. I don't understand why people keep thinking/ saying it's coolant temperature. It has the ISO symbol for oil temperature on the gauge.

[@youtubejunkie8053]

Why not get the COBB AP and have access to all that info and more? Not to mention get it tuned by Stratified which in the best in the business

[@mikef3300]

My MK6 Golf R has none of these digital gauges but the dyna audio system sounds great so there’s that lol

[@bigcat1158]

My buds omni glh had a similar issue factory it runs 6 to 10 pounds we opened it up to run 14 but from time to time it would spike to read 20 that was on an after market boost gauge but it was also in 2002. Meter would do that but air fuel mix never changed .

[@takeomack2782]

Another fantastic video Charles! 👍👍👍

[@TrevorReaStewartnexus]

I don't think it's dumb. It's just absolute pressure displayed in psi...

[@JPMotorhead1993]

It’s strange how they bothered to convert from bars to psi to display on the screen but not psia to psig

[@HumbleMechanic]

Exactly!!! Lol

[@DigitalDissident]

Hey what is the approximate maximum boost pressure of VAG 2.0 TDI Stock( 110bhp ans 250nm torque)?

[@ABeans07]

Can you do a how to on the p3. Using the analog inputs. Maybe oil pressure?

[@TheManLab7]

I know it's got a lap timer, but it's a shame it hasn't got a 0-60mph or 0-100kmh. I know other cars have them and so does pretty much everything that's got GPS (like some satnavs or things with a gyros which pretty much EVERYONE owns. Do you know how to get into the OBD settings and get engine oil pressure, gearbox oil pressure and gearbox oil temp on the centre screen? As I'd love to get it on there 😊 I know you can get engine oil temp on the clocks/drivers screen and engine water temp is always at the bottom. I know if that went either high or low you'd soon know about it before even looking at the water temp 😂

Any way to change programming on the factory to show gage reading?

Does the OBD connector have the female side so you don't have to unplug it when hooking up a scan tool? Or do you simply unplug to do any diagnostics?

Is there another turbo I should use to achieve my low rpm boost goal ?

[@zekeballinger4016]

Is there a max boost reading that the p3 sees from the obd. I’ve heard that it never shows more than 22psi, even after you tune it. Unless you run the analog boost line.

My E82 is N/A. What's the best way to increase power & remove weight up front in the engine bay for a reasonable price? Supercharger...

Before I went the SC route, I would be sure I maximize all other aspects. Remove weight, top line tires, light wheels maybe. Then I would look at power. But it depends what the overall goal is, is this a track car, or a weekend fun time

[@MiniAdler13]

is there an option for current speed display? I have it displayed in the center dash but it would be cool to be able to put something else there.

Yes. There are a bunch of different displays

[@brandonlynn4952]

Hi I have a b6 passat 2.0 fsi engine engine has a lot of oil in intake and is leaking a lot of oil. I suspected the pvc as being faulty when I pull the dip stick or oil cap car runs rough and vaccum. I would think that nothing should happen if oil cap is off or dip stick pulled while running. Can you please shed some light on this situation thank you.

[@HumbleMechanic]

If you pull the dipstick or cap you upset engine vacuum. It will run poor. May still have a bad PCV but the rough running is normal

[@levigato125]

Nice job. You need to buy the Badgeskin to cover up that ugly bright amber air bag light.

why your G sensor has no data?

are the carrier to spindle bolts on the mk 7 platform TTY? or does that only apply to the caliper to carrier bolts where the caliper slides on?

[@p3gauges837]

We have analog versions of most of our gauges that only need a power/ground connection and read boost directly from the intake. They can read battery boost, battery voltage and 2 analog inputs. Also, you can switch this OBD2 gauge over to analog and back on the fly.

It reads boost from the ECM, and presents it better than the OEM gauge.

Hey VW experts. I’m in need of some desperate help. I have a 2013 VW Tiguan. It’s a 1.4 tsi, check engine light came on. I scanned it and it has only 2 codes. P2178, and P2188. Engine running too rich at idle bank 1. The car starts, runs and drives perfectly, there is no smell of fuel at the exhaust, car doesn’t hesitate or anything. It’s rather strange! I took out both MAP sensors, sprayed them with MAF/MAP spray, let the air dry. After much frustration and screaming I took out the “interestingly engineered” coil packs. Removed the spark plugs, they where all the same across the board, all had the same normal carbon build up, no one of them looked cleaner than one another, all normal. No smell of fuel in the spark plug holes, they all looked dry and normal. I looked at some of the OBD parameters, the air fuel ratio at idle was 14.65, the fuel pressure was around 790psi and the O2 sensor was reading. I really need some help from you guys, I’m just an enthusiast and I’m not too knowledgeable in VW specific stuff. Thanks so much everyone I really do appreciate any help and hopefully solving the problem. Anything else u guys need to know to figure it out, please ask. This is the second time writing this out so I’m sorry for any mistakes! 😂

[@InBoostWeTrust7MGTE]

i will guess why without watching the video as the thumbnail is the question. Its because compared to traditional gauges where 0 means atmospheric pressure but actually is around 14psi, this one shows 14psi when it sees absolute atmospheric pressure. In other words - N/A car with this gauge would show 14psi with 100% throttle. EDIT - kinda stupid thumbnail. Video was not about why that gauge shows 40psi, it was boost gauge install/how to...

Performance Monitor for VAG (third party app) does pretty much everything the P3 can do. You need a rooted android phone and a BT OBD2 dongle/Torque Pro App. It relays the info from Torque right to the AA Interface/infotainment screen. You can select and choose what data/clock themes you want and everything. Costs far less and is basically what the stock performance monitor should have been.

@HumbleMechanik, my polo gti aw 2.0 tsi shows always ambient pressure, normally when i let the foot of the throttle it showed me about 0,33 bar when rolling in gear.

Also i have this strange sound @ about 2000 rpm when i let of the throttle. kzbin.info/www/bejne/aITOiImBapuBgNk
