Ok I want one of these realllllly bad. I've been looking at a few of them, but never personally used them.---Any info is GREATLY appreciated.

http://cgi.ebay.com/ebaymotors/Windo...spagenameZWDVW (He has the exact same thing for nissan's it's just not online right now)

I am very eager to buy one of these. I talked to the guy on the second auction and said he would do a gb for 10-$90 20,-$85 shipped (Waiting to post till i get some info from users, not just the seller, I wouldn't be making any money on this- all transactions directly to him thru ebay just getting in on gb price.)
I have a few questions for people who have used these.---We have a scope at work -Fluke 98, Mastertech, Tech2, ETC. I asked another guy about these there and he said they where okay. He said this is the reason they went to obd II and these should work as well as a $6000.00 mastertech. That all prices will come down drastically by 07. I'm not sure I buy this.. I have 3 Main questions
1.) How are the scopes on these? I.E. reading time measurement....For example if I want to read an 02 sensor and the test/fail says the lean/rich scope says it should change from .3 to .6 volts in say 200 Milliseconds.- Do these scopes really have CONSTANT live feed from the sensor thru the pcm? Or do they do something more along the lines of take a measurement of the 02 every 100 milliseconds or so and draw a "constant" line between readings? ---This is a steal if it has a constant real time scope that doesn't just give "snapshots" every .1 of a second and draw a line looking like live feed.
2.)It has a so called "dyno"--are these b.s. or what??? Can anyone claim to their accuracy as compared to a REAL dyno??
3.)the virtual E.T. Slips. (60 foot, 1000 foot, etc) How does this work??? I am assumming that it reads the mileage and speed thru the pcm analyzes this data and converts it into 1/4 times etc using the laptop clock.---Does the pcm odometer gauge go by .10 miles or .001 miles??? I mean the scanner would know where you where when you hit .2 miles but how does it know .25 miles? Does it calculate the difference or does the pcm odometer show in .001???
If this thread is confusing and I appologize, I will try to clean it up if its hard to read.

My main interest is the DTC and scope capabilities, the others are just a huge added bonus.
Think of how much time at work this will save me :-)....Hell I could check my maf with a laptop in the heat of my car..

 

I want it, I want it....I'm heading to the stang forum to see if they know..........Maybe with their help we can get 20 of these bad boys... $85 sounds good to me if they are any good..offtopic and bump.

 

I have an old one called AutoEnginuity or something like that. Paid about $125 or so, and just used it the other day after buying last year. Its OK. It does give you real time stats if you need it. There is a second delay or two before the readings come up to the computer screen. Remember, its through serial port, so you'll only get so much speed and I/O.

 

So, if for example you are checking the 02 sensor it will show lean/rich, lean/rich, etc in a constant manner? It won't "cut out" for a second and take snap shots.... Or lets say I was checking my TPS and put it on scope to look for dead spots. As I slowly open TPS to WOT it will show a gradual bar of Voltage increase not just .73 volts and 100 milliseconds later do 1.2 volts then 1.5V and draw a line between them, etc?
Also this may be a newbie question but....I/O???? I'm unfamilier with this term. Input/output??

 

You are speaking of the Laptop Serial port correct? It looks like these connect thru USB, so the delay should be slightly less than serial I would assume?

 

i'm down for one,let me know!!

 

can you advance your timing with this or is that something only the stealership can do?

 

You can't necessarily bump your timing with one of these....But depending on the tools capabilities you could bump your timing and keep your knock sensor on the scope until it picked up "ping" then turn it down 1 or 2 degrees.
Information like these capabilities are exactly what I am looking for.

Kinda off topic, and I coudl be wrong but don't these engines constantly electronically bump timing as advanced as possible before the knock sensor picks up detonation then retard it, then advance it until the knock sensor picks up detonation, then retard it, thn advance it until......, etc, etc ,etc for top fuel economy and performance??--I may be wrong, I just thought this is the way it worked...

 

hmm so true. Well, you are right. If you get it, please let us know how you like it. Thanks!

I have the OBDII package (universal connector, all 3 type, domestic, european and jap) and the software.

I bought it on a forum GB few years ago. I had lots of fun and it has lots of diagnostic tools.


Anf funny thing is... i have had the Maxima for a year now and I still doesnt even know where the OBD port is in our cars!!! Never had the time to connect it on the maxima.


Important note: I bought it to use on my Ford Contour.. and those guys at CEG.or had the Ford standard parameters for the car.... that thing was useful as HELL. Best way to explain:


the Ford diagnostic parameters is something like this: warm up car and drive at constant 25mph, then 50mph and so on. And save the data from the OBD software (throtle position, crank rpm, IAT, MAF mass, etc) and u can compare to the standard values from Ford. Pretty kewl.

The OBD II is legally mandated to be within either 16 or 18" from the steering wheel. Probably under the front dash, possibly under the passenger dash I haven't checked myself yet but not hard to find.

 

It's right above your knee under the steering wheel. When you go get your car inspected, watch where they plug the OBDII and that's where it's at.

 

So basically you did the diagnostics and let them tell you what the hell was wrong.

 

no no no...


All the work is done by myself.


I got the standard values from the Ford Manual service and I compared to the actual readings from my laptop.


For instance, the diag sheet asks you to drive at 25mph and the readings on the TPS (u'll read it on the laptop) SHOULD be around 15% on certain gear. Now if ur reading is like 50% then u know u have a problem on that sensor.


This exactly way, you can check MOST sensors to what Ford (or Nissan ) has estipulated/tested/calculated (well... in Fords case i think it is GUESSED more than tested)



anyway, nice little tool.

I was j/k. hehehe

 

If you could get a groupdeal going, I'll be down for one.


steve...

 

does this let you modfiy things/ update ECU/TCM etc ?

or is it purely for reading information? Id be more interested in one things I could do to tweak with this

 

as far as I know...It's purely for reading info.....You can check voltage of maf, each 02 seperately etc..You wouldnt have to condemn and replace your maf before checking it.--I'm looking more into it, but with the expensive ones you can turn your trans shift solenoids on/off etc. I wish someone on here had one and coudl tell us more... Guess I/we will be the first with this???

 

after doing much research, I think there may be better out there for the money. It does have EGR command capabilities, but I'm not to sure about the "live feed" capability.
I'm going to keep looking for a higher quality one, at a decent price. I know a guy with a DSM who has a different brand. I'm going to check his out, maybe I can find a way to make up the plug and play adaptors from radio shack. For the software....well..I don't want to break piracy laws, so I won't say anything else and we'll see how I like his software...I'd hate to GB something that people may be disappointed in, just so I can get a decent price. So I'll test his out sometime in January, and if it's worthy I'll update this thread and start a gb (or find a way to make the adaptors ourselves) on that one instead.

 

I've been using this for about a year now on my 2K max.

http://www.digimoto.com/

got it on ebay for about $80.00. Check out the web pabe. There are demos of the software there.

The only OBDII write operation allowed is to reset the SES light and clear codes. Everything else is read only. That is the spec in the OBD standard.

Make sure you get an ISO interface for Nissan. Most auto makers use different communications protocols for OBD readers.

 

It is true. When I bought my connector I had 3 options, like ISO, american and something else.

I bought the 3-in-1 connector... it was only $20 more.

Yeah I was just about to purchase this one
http://www.obdcom.com/
$79.99
So I'll wait a little bit, and put me down for one also.
