I can't comment on that particular unit, but I can comment on the UDX and the general quality of the company.

In summary, I'm really quite disappointed by the quality of the equipment. They're flimsy, the software has bugs, the support staff doesn't know how to answer very basic questions, and the unit is a little difficult to use.

I'm very picky about software in particular. You have to do what's advertised in the specs. If not you've sold me a defective product. Comes from my software engineering background.

I guess the quality of the support is better than most in this segment, but I had some really simple questions that they couldn't answer, like for example, the UDX has a setting for the VSS that specifies pulses per revolution, another one that specifies total pulses per 1/8 miles, and another one that specifies total pulses per mile. I don't understand why you need to spec pulses per rev if you're already spec'ing pulses per 1/8 mi or mi.

So far the support staff hasn't been able to give me an answer. I thought it would be a very fundamental question since they designed and programmed it.

On top of that, I had various software glitches in my unit. For example, some of the settings don't work the way the specs advertise, if I go into setup mode I lose my odometer reading, other minor stuff that really add up to irritate me.

I don't have any datalogging functionality in my unit, and from my experience I speculate that I would be tearing out my hair and on the phone with them every other day.

All this leads me to believe that their engineers and programmers really don't put quality into their work. They don't check and debug like they should.


I hope you have better luck than mine. At this point I'm even considering getting rid of my unit and fabricate a display myself.

The #1 reason why I'd get it is for data logging. Does yours not work due to software bugs or is it just not available? I've been thinking about picking one up but if their data logging is buggy then I'd be extremely pissed.

Since my car is street legal, I'm using their UDX display-only dash for now. I can upgrade to datalogging in the future if I wanted to since it's offered as an option.

To be honest though, I'm carbureted so there would be little tuning benefits other than to dial in the carb.


The software itself is very tempermental, especially the interface. I haven't seen the code, but to me it feels like their software engineers didn't tie up their lose ends. I speculate that they have a lot of loose ends in their modules, like not doing error checking, exception handling, out-of-bound entries, not resetting/initializing loop counters, not reading the specs, not programming according to the specs, etc.

I haven't had a chance to play with their data logging software, but I know how exacting you are Gary, and I think you would find similar annoyances that I found.

All this stuff is okay if you're just doing displaying-only, but I'm guessing that if the software screw up with the data logger functionality and it dumps/corrupts your data, you would be royally pissed.

[blu808]

That is good to know.

Do you have this exact same model?

The price seems to good to be true.

[McRussellPants]

Losey just bought one of those for his LS1 240SX.

I haven't seen it yet but it seems fair enough.

I'd love to get an IQ3 or AIM, about the same cost as the equivlent amount of defis anyway.

[blu808]

Yea I really like the features of this over the aim.

This one also has gps mapping.

sweet.

[blu808]

Anyone interested in starting a group buy?

[g6civcx]

That is good to know.

No, I have this: http://www.racepak.com/UDX.php

The UDX has very limited data logging capability, but it's much cheaper than the rest since I only wanted display.

I'd put that in a Z31 with some brake fans on it and jam to the outfield while driving around a track

Yea. I have heard mixed things about that display.
How much do they go for?

i'd rather use the g2x

[blu808]

Why is that?

[racepar1]

I fuckin HATE digital tach's though! That is my favorite thing about the stack dash, analog tach = WIN!

What are you calling digital and analog tach? All the tach signals are digital.

Do you mean that you like a needle gauge as opposed to a numeric display?

These dashes can display both S2K style sweep display or numeric display. If you don't like that you can get a standalone tach.

[blu808]

yea that is true, the defi ultimate dash is also bad ass but twice the price.



The racepak does have a sequential shift light though.

Digital and analog are obviously describing the display! How would you get an analog tach signal? Also a digital "sweep" display does not = analog style tach. In my opinion the analog display is easier to read and just plain looks better. If I am going to spend a crapload of money on a datalogging dash why would I want to buy a seperate tach when I can get a dash that has the tach that I want with superior datalogging features? Makes no sense.

[blu808]

I agree. But to be honest. Out of all the times I have been competitively driving, I have never needed to look at the tach. at all. I have looked at it, but only just because. You should be able to tell where your engine is just by the sound. I think that combined with the sequential shift light will make it work just fine.

Also the only thing I have ever really used a tach for is:
Dyno tuning and figuring out what rear end gear size to run, back when I used to race shifter karts.

[racepar1]

There are TOTALLY ways around it. But if I am going to spend a crapload of money on a dash, I am going to get EXACTLY what I want.

[blu808]

Well here is the solution to all of our problems but this is like $2100 or so. Not including senders. And it doesn't have gps.

[racepar1]

WOW! That is pretty cool, but I still think the stack looks better. That one is pretty cluttered. Also since I am not planning on going with a turbo set-up the built in boost guage would be useless for me. I think used stack unit is the way to go for me. When I win the lotto or rob a bank or some shit cuz that shit isn't cheap!

[Gnnr]

Yeah, Kuah posted an install on one of those:

Shit is baller indeed.

I originally fell in love with the stack one originally.

Just makes more sense to go with the racepak

Ya but does spending thousands upon thousands of dollars on a car that you can buy for $500 if you search hard enough (s-13) make any sense in the first place? We're all fucking nuts!

[g6civcx]

Digital and analog are obviously describing the display! How would you get an analog tach signal?

This is not obvious. Any electrical engineer will be able to tell you the difference. He didn't say which is which so I didn't want to make any assumption. I don't want to get technical (like how a tach signal is a sine wave or square wave that gets converted to a digital pulse).

The easiest way to describe it is a real number and an integer.

Also a digital "sweep" display does not = analog style tach.

Needle tachs are actually digital displays because the needle is supposed to move a fixed distance for each pulse. The inaccuracy of the OEM tach makes it feel like an "analog" display with infinite range of display.

If you are referring to a needle tach then say needle tach. I don't understand what's in your head when you use these vague words and assume others to instantly know what you mean. No offense so don't take it personally.

In my opinion the analog display is easier to read and just plain looks better. If I am going to spend a crapload of money on a datalogging dash why would I want to buy a seperate tach when I can get a dash that has the tach that I want with superior datalogging features? Makes no sense.

Do what you want. It was just a suggestion.


Again, I get this "analog" vs. "digital" argument all the time from attorneys and people with no EE background. It's somewhat a pet peeve of mine. Don't sweat it. Just be clear in what you say, or at least point to a reference that says what you mean.

Take it easy. :coold:

[S14DB]

Do any of these have Hobbs meters?

[racepar1]

A "needle" tach is an analog display. A "digital display does not have a moving needle, it is an image displayed on a screen. I have never heard anybody describing a tach signal as "analog" before. Everyone else that read my post except for you understood exactly what I was talking about, maybe your just too much of an "engineer" for your own good.

[Dousan_PG]

no shit
get over it.
haha
i like analog tachs
id totally get the AIM if i was datalogging
but im not.

[fbiphil]

A little off-subject, since this thread is about the digital dashes, but old hot rods and many motorcycles used a cable-driven, true analog tach.
I believe the reason was that you couldn't pull a tach signal off the magneto-style ignition... but I could be wrong on that.
Again, not trying to get too off topic or start an argument!

[racepar1]

^^^I believe you are correct. A cable drive is my idea of an "analog" signal.
