Unless I'm mistaken, I don't quite understand why you would need 0-5vdc inputs for the variables yoiu want to monitor in the HUD as all this info is available as well as much more via the OBDII port.

If you're plugging into OBDII port, then you should be able to access this data the same as AeroForce Gauge does without additional sensors or wiring.

For your reference, here is their link:

Correct me if I'm wrong on my assumption.

Edit: Doing a little more research, it looks like fuel pressure is not reported on the OBDII port so a sensor would be needed. Boost/Vacuum as well as AFR is reported as well as a host of other variables as outlined in the above link.

Thanks for the question.

We designed the GP for maximal versatility to integrate with the voltage outputs of many wide- and narrowband sensors. Any two signals that do not exceed 5 volts can be named and defined for display once connected to the GP. Boost and AFR are only two examples. You can monitor other wide- or narrowband sensors too, for example exhaust gas and general fluid temperatures.

blend this with the the v1 interface and i be sold!!!! I will take v1 date in hud and boost and afr in dic!!!:D

The Radar Projector and the Gauge Projector are two separate units.

They do work together.

You can have the Radar Projector have the V1 displayed in one location either HUD or DIC and then have the Gauge Projector display other location HUD or DIC.

Above, Dashtronix says their projector uses the spade lug terminals. The implication is that it does not grab the ODB data. I guess they need to answer that.
Larry

Correct.

The Gauge Projector is a unit that allows you to take any linear 0-5 volt external signals and then define and display them in the HUD and DIC.

The install instructions are available at www.dashtronix.com, it has all the info on how to hook up, program and use the Gauge Projector.

Dashtronix guys,

I just looked at the documentation and the TVS package reuses the stock MAP sensor, so I guess it is 1.5 bar. How can this be used?
Also, since I am addicted to my V1 display on the HUD, can the projector be used t'd into it and which would have priority?

Larry

Hi Larry.

What is your current boost level? The 1.5 bar MAP is good up to 7 psi.

The GP is able to work alongside the RP. You'll need the OBD-II splitter cable
to be able to connect the both at the same time.

lsbrodsky 08-02-2011 04:41 AM

This is not entirely clear. I would have to run a wire from the MAP sensor to the spade lug on the projector? Would it be possible to have both read in the HUD such that the boost is normally there, but the radar or NAV data would override when it comes in?

Yes, you need to run a wire carrying a 0-5 volt signal from your MAP sensor or other boost sensor to the GP unit and attach it at the spade lug terminal on the GP unit in order to display boost.

You could have both units display on the HUD. It would operate like it does when you have Nav Data and RP radar signal at the same time. They will interleave with each other and alternate between the two readouts.

We find it best to display one unit in the DIC and one unit in the HUD in order to view both data sets at the same time.

Its up to your personal preference though.

So I need to purchase two units, correct?

Correct. You would need a Radar Projector, a Gauge Projector, and an OBD-II splitter cable.

What is the response time and refresh rate for Boost/AFR readouts? Do you have a video of a boosted car that will give a sense of the two?

x2 i was just going to ask the refresh rate and out fast it samples data, boost comes on quick and afr can go lean real fast!

If you change the design of the Projector so that it can grab data from the OBDII, that it is plugged into, count me in. But I don't want to go to the trouble of splicing a wire to my MAP sensor and then running the wire from there into the cockpit to the projector. Thanks...it is a great concept.

:iagree:
Agree completely. Will go another route because of this.

Exactly my point in my Post #17. The info is already available at the OBDII port (except Fuel Pressure).

carnutsx2 08-04-2011 07:13 PM

OK , I like the idea so far but how about a all in one unit that will display directions for nav. from an aftermarket deck. Hey I know it may be a dream but I've got to ask!
Thanks

The Gauge Projector is reading the 0-5 volt inputs 16 times a second.

It is able to refresh to the HUD or DIC as fast as 60 milliseconds.

Thanks for your post.

There is no wideband AFR on the OBD-II port so what you are reading is from the narrow band O2 sensors which have a very narrow range.
The main problem with any narrow-band O2 sensor is that the ECM only detects that the mixture is slightly richer or leaner than 14.7:1. The ECM does not measure the operating air-fuel ratio outside the stoichiometric range.
You cannot use narrow band info for performance tuning or monitoring under boost as your AFR is below the accurate range of the factory narrow band o2 sensor.

The Boost that you can read on the OBD-II port on a stock 1.5 bar MAP car is only up to 7 psi boost. So any cars producing more boost than this will not be able to read it from the OBD-II port.

We designed the GP as a unit that you can input any 0-5 volt signal and define its label and its ranges.

With the GP you can display boost up to any max you want, and display the output from your aftermarket wideband 02 sensor or anything else that uses a 0-5 volt linear signal.

This allows using it to display whatever you want that uses the standard 0-5 volt linear scale.

Hi Larry,

See the above post. It answers why the GP was designed the way it was.

Thanks,
