Digital Gauge suggestions

I would ulitmately like to put digital gauges in my vehicle. I love the functionality of the scan gauge, but I can't find any information anywhere as to whether it supports realtime output. If not, what's the best alternative to the SG that does support it?

What do you mean by realtime output? If you mean can you capture data from it on another device (palm, laptop), no. But the digital info available on it is live (eg. all the gauges, instant & avg fuel consumption, etc.)

the only real time signals are signals in the time domain, not sure what parameter you want to look at? digital displays by their very nature have some averaging built in or the human eye could not see them. if your testing at steady state conditions, a reasonable delay might actually be beneficial, e.g. when the dispaly stops changing, take your data point. tell us what you want to do.

Welcome to EM! What's your price point? The SG is around $150.

If you want to go hardcore, then I would do a lot of research into a tuner gizmo like this :

Apexi AFC NEO-FUEL "Piggy-Back" Color Display Air Flow Converter Computer - $370
http://www.2kracing.com/product_info...b83c867b5463c3

Quote:
- Compact "Piggy-Back" Fuel Management Computer (+50% ~ -50%). - Unit incorporates both the SAFC and the VAFC. - NEW "Easy" (8-Point) & "Pro" (16 Point) Modes. - NEW Color FED Display & Interchangeable Button and Background Colors. - Inverting "anti-glare" screen allowing view from both angles. Monitor Mode: - RPM, Throttle, Battery Voltage, Correction %, Air Flow %, Pressure (Kpa), Karmann, VTEC Setting Mode: Air Map, Air Map Graph, Throttle Point, Deceleration Air, VTEC Control, VTEC Unmatch Etc. Mode: MOdel Select, Mode Select, Sensor Select, Analog Select, Warning Set, Display Set, Sensor Check
Hrmmmmm, I don't see MPG in the list above, maybe not so good, .

It's also a lot of upfront cost and that's NOT including installation, which would be more than the super simple "plug it in" ScanGauge. But, I think it could end up giving you more flexibility in the long run.

What I want is something like the dashdaq that was mentioned on the page Who linked to. I like the data that the scan gauge provides, but I want a realtime (or near it, I understand that realtime would update way too fast) data stream to an external computer which could be used to display and analyze the data. As I understand the scan gauge's only interface to a computer is to disconnect it from the obd2 port and plug it into a computer to download a batch of data. Basically, what I'm looking for is the cheapest/best/easiest way to interface the ecu to a computer plus any recommendations or advice from anyone who has already done this.

That's almost exactly what I'm looking for! Actually now that you point that out, it looks and sounds very familiar. I think found it a couple years ago and forgot all about it. It's even compatible with windows AND linux. Does anybody have any experience with these?

I have one but I haven't got it to work consistently. But, it may just be a function of the car it interfaces to. It was fickle for my Saturn.

Also, all the good Software costs extra $$. The free software doesn't have good downloading capability (that I have found).

It's main virtue to me was that it shows the 02 sensor(s) and short/long term fuel trim, which the SG does not (boooo!). I got discouraged so I put it on my back burner list.
