jetta hybrid gauges, say goodbye to sg2

[ever_green]

The new jetta hybrid comes with a giant vacuum? gauge instead of engine RPM tachometer:

So......... You say because of this new gauge you do not need the sg2. You then say because of this new gauge you need an sg2 because you cant see rpms?

you misunderstood or i didn't word it properly; i never said i need sg2 because of rpms, I said there is nothing like a good old fashioned rpm gauge AS in a RPM tachometer on your car. I never use digital RPM gauges, it's just not right lol.

Thats not a vacuum gauge.

Technically, it is not a vacuum gauge as it measures positive pressure when the turbo is doing its thing, but, it is essentially the same thing, I think.

It says %PWRx10 right there on the face. So it seems to be a power gauge.

(Same thing you'd get in a Bugatti Veyron or a SSC Ultimate Aero.)

So this lets you see coolant and intake air temps, charging system voltage, loop status, etc? Not to mention read & clear codes.

Methinks we'll have the SG and such around for a while. Which of course raises the question of why automakers don't make this info easily viewable.

Probably because they would consumers flipping out every time the temp read 187F when it normally reads 185F.

Ah the coolant temp is in the picture i posted above, that small gauge.

Many cars already let you do that, it's just a simple obd2 reader. For example ford mustang lets you monitor AFR, coolant, air intake temp and etc. My acura had this diagnostic menu system which could be accessed using the navigation to read or reset codes.

VW has this as well i think since 2009 part of their MFI/MFD menu system, it displays coolant temp, oil temp, outside temp, engine run time, battery info and lot of other stuff i forgot.

Yes that's because an average consumer doesn't know what a torque or load gauge is. This sensor works by reading manifold absolute pressure, which is MAP for short...like on your scangauge 2. Also LOD works with MAP sensor on Scangauge too. You could have 100% load at 2000rpm or at 6000rpm, but it doesn't mean your engine is producing peak power at 2k rpm, it's maximum torque available at that RPM. So as engine load rise, vacuum in MAP decreases. On turbo charged engines depending on boost MAP can rise above atmospheric pressure.

yep.
