I saw it on tv and thought, eh it might be kind of neat, but I bet its too expensive.
How's under 200 bucks for a chip that can tell you:
RPM
Throttle position
Engine load
Coolant temperature
Intake manifold pressure
Air flow rate
Intake air temperature
Timing advance
Fuel pressure
Fuel system status
Short– and long–term fuel trim
Oxygen sensor output voltage
Battery voltage

And it works for nearly all cars (obd-II).
Now if only someone could hack it and make it CHANGE parameters that would be the coolest.

I do have to ask, are our 95 models included in this or are we obd-I?? Cant remember if 95s fell into that category yet.

oh yeah heres the main link

This could be old news to some of you guys but I just had to post it.

 

Its a good idea but I like mine better. It will show you real time or as a datalogger on either a notebook or Palm.

I bought the most expensive version that works on both and also will work with ALL OBDII cars, it has 4 different interface modules installed.

Cost is $160 for all interfaces and software, it can be purchased with lesser variations for just over $100.

I have still not seen anyone with an OBD-1 95 Max. Here is a pic of my manuf date which is 03/94 and its OBD-II.

 

Does your software work with windows 2000?

 

Windows 9X/ME/2K/XP

 

Thats very cool.... i noticed a "Change ECU" box with a radio button in it... Is this just a monitoring or getting error codes tool?? Or can we change fuel maps? engine idles??? etc

 

Ok, yeah I like your option alot better, since I have a laptop it would be much better to have real time analysis at the track.

Can you change variables or is it just just a data logger? I will definitely look into this further.

How about with the JWT ECU? Know of any complications there?

 

Change ECU is because some cars, (not the Maxima) start up monitoring the Trans ECU and you hit that button to get it to switch to the Engine ECU.

Monitoring only, no changes can be made. The main reason I want it is to watch timing etc, you can see if the engine is knocking because it will pull back the timing. Its also nice to see the MPG feature, intake air temp, coolant temp, O2 Sensor volt etc. Its great with the Palm I just stick in on the dash with velcro, it will either show digital or graph and its a great gizmo to get into an accident with if you don't watch what you are doing.

Also reads and resets the engine code errors and will log 4 different items at the same time.

 

Sweet on both versions.

Jime, are there versions for obd1? ie.. 92-94 maximas?

 

Daniel its just a logger/monitor. I don't know of any issues with the JWT, it just takes its reading from the OBD=II connector, however I would try it first.

I initally was going to get the Pocketlogger, but I tried one out and although it does almost exactly the same as mine it will not work on all OBD-II cars ie 2k2 Maxima and just Palm operation. So I did a little more research and found this one, I use the laptop for serious stuff because you can see more at one time but the Palm still gives all the same info you just can't see it on the screen all at once.

 

Jeff they don't list anything for OBD-I at all at Harrison. There may be other companies but I really don't remember seeing any when I was researching it.

I just bought a 95 and I just about turned down the deal because I couldn't find the OBD-II plug (its not under the dash drivers side like my 97)so I thought it was probably OBD-I because it was manufactured in 04/94.

However, I went home and checked it out on the org and found the OBD-II connector is on the pass side under the cover for the ECU, so I went back and hooked up my palm and bought the car, when I knew it was OBD-II.

 

Good find Jime. Definitely a good tool for mechanic and tuning use. I'm glad the mpg works, but it's too bad it's only on the palm. If I get one it would probably be the universal kit that you got.

Are there any settings that aren't applicable on our car i.e. fuel pressure, etc.?
-hype

 

this is neat, but buried on their website is this little tidbit (my bold)... "measures up to four engine parameters every 5 to 60 seconds (and there are 23 parameters to choose from!)"

So there are 23 things to choose and you get to log only 4 of them. Other choices presented here are better.

 

The MPG works on the notebook too, I was just stationery when that pic was taken. All features are identical. I did lie a bit about the data logging on the Palm its not yet released but should be in the next couple of weeks according to Dan Harrison the owner. The laptop data logger works fine.

The interface is for all OBD-II vehicles so some settings are not applicable as you stated. It knows which ones work and don't when you hook it up and just shows the applicable ones. The ones you see in the picture are the ones that work on the Maxima.

Apparently there is a wide variation of items that it checks on different OBD-II cars so its pretty smart to be able to pick out the ones that work and display them only.

Also some vehicles I have checked it with, it just displays the numeric manufactures fault code. (These are available on the supplied CD) However on the Maxima's I have checked it shows the complete fault in plain english.

 

I saw this too after I posted it, Jimes's option is much better because it offers real time analysis of all of those options. The only caveat is that you need at least a pda or laptop to operate.

I wonder if the venom nitrous kit with the pda controller has a system similar to this. All they would have to do is program in an interval for nitrous and make outputs from the control box for it.

 

How many settings do you want? It would be cool to log more features at once, but to be practical 4 is plenty. You'd spend forever going through plots if you logged more features.

For racing/tuning purposes you can choose a few parameters to log, and keep adjusting till you're satisfied. Same goes for troubleshooting mechanical issues.

At the cost listed, this package is also considerably less than any of the sensors provided by the major manufacturers, Apexi, etc. (assuming you have access to a computer).
-hype

 

but other options here provide for more logging and do so for less money, so I'll turn the question around... why would you buy a product that limits you to logging only 4 things when there are (as shown) products that log more for less?

 

I'm not saying you're wrong, but the data loggers/tuning equipment I have seen logs very little and costs quite a bit. The Apexi line is a prime example: SAFC, AVCR, RSM.

If you have more knowledge of equipment do share
-hype

 

Nice... does anyone know how this thing (Harrison) compares to the Autotap? www.autotap.com

 

Like what? Share the info if you are able. It certainly would be appreciated.

I think you guys got 2k2wannabe confused, he was talking about "davisnet" one that logs 4 out of 23 and cost more.... and by other options for less $$ he was referring to the Harrison model...

if im wrong then please share ur info

 

Anybody use, or know anything about, Auterra? www.auterraweb.com

 

I did not see a Nissan application on their site.
