I am looking into getting an ODB II reader and would like to setup a system to run through my laptop. I did some searching and stumbled across this:
ODB II scanner

What do you guys think? Any recomendations?

Jime

I have this one, I wanted one that would data log as well. It also works with a Palm which I use in the car all the time, much smaller and easier than the laptop.
I do use the laptop for serious testing because it shows more on the screen at once.

This is pretty funny. Just today Scott and I were trying to decide which one to buy. I was seriously looking at the Harrison unit that you recommended in another thread. It's much cheaper than the Autotap , but I don't know just how vehicle specific they are.

Anybody know anything about Auterra?

What exactly do you mean by vehicle specific?

It works on all OBD II that I am aware of if you get the Whole Meal Deal interface. It also only shows what each particular vehicle is capable of, ie some cars have many more readouts than others. For instance we do not get fuel pressure readings because our vehicles do not have a sensor for it.

I have not tried it on a 2k2 Max yet but have tried on a 95, 97 and a 2k plus a bunch of other cars.

I can give you a list of what it reads on the 4th Gen and what checks it does.

SR20DEN

iTrader: (7)

Thats exactly what I was talking about. Autotap claims there are generic readings then manufacturer extended readings. So long as I can monitor most or all of what the ECU reads and I can clear the codes I will be happy. I also want the universal kit so I can plug it upto other vehicle makes as well.

I was considering the Equus reader, but I did not like the limitations of the UI, and that is what prompted me to look for a PC based system. If you have been happy with yours, then that is all I needed to hear. Does it come with the adaptor for the palm?

Jime

iTrader: (10)

You can order it with the unit, the Palm software is an extra, it comes basic with PC software. The output from the convertor is a standard 9 pin serial so it can adapt to either PC or Palm. I already had a Palm serial cable so didn't need one, it also needs a null modem cable for the PC which is available anywhere for a couple of bucks.

Mine was $169 for all the interfaces and no Palm or PC cable, the top one is $185 and comes with all Palm and PC cables.

I can vouch for this one too. I showed this to my friend after Jime posted about it the first time. My friend got it and has used it on quite a few of my friends cars and mine. Pretty cool. Works best with a laptop though. I still have to get the log from the run I did with the unit attached. But I think this thing is a great deal. The box and cables are top rate.

That would be great, thanks.


Scott ordered one yesterday so hopefully by this weekend we will be S-AFCII tuning from the data logs.

tecman4

would this software be able to change things like how the locks work, windows, how long lights stay on, stuff like that.
I know that the dealership can change these, is this what they use?

ZuMBLe

iTrader: (1)

No, it won't do that. It just reads the engine control computer.

I can't wait to get my hands on this thing!

I haven't checked it out too extensively yet because I am still working on a bunch of other stuff. I have the S-AFC II also working and same story.

There are a few of those items I haven't checked out or looked into yet so I don't know too much about the whole setup yet.

Hmmm...

studman

Has anyone actually used a unit that displays the air/fuel ratio? I'd like to make some adjustments from time to time using my Greddy E-Manage (like setting up for a track run) without having to visit a dyno everytime.

SR20DEN

iTrader: (7)

This unit should show us that in either O2 voltage or A/F ratio. That is exactly how I plan to tune with my SAFC-II.

studman

Exactly. What air/fuel ratio are you gonna try to tune to? I can't find the optimum air/fuel ratio in the ESM anywhere.

SR20DEN

iTrader: (7)

It doesn't need to be in there because it's 'not adjustable'. My thought is that 12.5:1 is a generaly good ratio for this engine under WOT above 3500rpm. The 11:1 ratio that Scotts' car is running is WAY too fat. My initial results with the SAFC is pretty good. Try -1% MAF at about 3600rpm and taper that to -6% at redline and tell me what you think. As many trips to the 'Humblemaker' I have made I rarely ever make a guess statement on hp or even claim to notice gains but after 6000rpm that setting is pretty obvious on the butt. I had a passenger notice the same thing, and so did Scott when I set it in his. But since your Emanage is a different animal it might not be the right setting for your application.

studman

My results:

I didn't really notice a difference between 13.7 and 12.5 until 5500 RPMs. From there, I kept the 13.7 to 14.1 on one run, and let the other work back down from 13.5 to 13.0. The first run (13.7 to 14.1) got 7 HP higher at 6200 RPMs than the second (13.5 to 13.0). So it appears that we need to lean out the car at redline, but give it gas in the lower end to create the torque.

I know it's OT, but it's useful. I just need to find a unit that can display air/fuel mixtures. Maybe I'll contact Greddy to see if the E-Manage can display them. Does your S-AFC II display it?

SR20DEN

iTrader: (7)

The AFC does not even though it has the O2 hookup. I do have an A/F gauge to work with in the meantime for a general reference. I can't see how anything above 13.5 could be healthy for this engine at WOT.

studman

Healthy vs. HP: The never-ending saga.

That's partially why I wanted to be able to test the air/fuels off a dyno. Because I'm finding that there are 2 seperate settings that the engine likes. I'm not 100% sure why, but I think it has something to do with the internals as far as injector spray vs. air intake routing (after butterfly valve opens). Until I can find a unit that does air/fuels, I'm stuck to only testing on a dyno ($$$) which may take a while for the results to be in.

What air/fuel guage are you using, and is it digital?

All: Anyone know of an ODB-II reader that can display air/fuels (besides the $4300 Consult-II)?

SR20DEN

iTrader: (7)

I have the Autometer one and it's connected to primary O2 #1.

And once again, im certain this Harrison unit will show us what we need to know for A/F.

HitManSE

iTrader: (1)

For the best A/F ratio readings I would think the most accurate setup would have to be the wideband O2 setup that JIME is currently running. I dont know what A/F setting is the most optimal setting for the car, only dyno tuning could tell you that as im sure you all know.

deezo

iTrader: (3)

I have the Equus and love it. If you want more features like the software scanner has, go for the software version.

SR20DEN

iTrader: (7)

Scott recieved the Harrison unit today and we checked it out on both our cars. It clears codes instantly but has a problem with the codes themselves. It can't read the error codes we had.

But the data loggin seems to work fine. I hope they make a software to convert the O2 voltages into A/F ratio.
One thing we tried but could not make work is run verious other OBD2 scan softwares. None of them would work with this unit.

Jime

iTrader: (10)

Thats funny it read all my codes directly out, ie O2 Sensor, knock sensor etc. Maybe its because its a 2k2, so it just gave the error # and not the specific error?

It did that once on a new truck I tried it on.

You will find that all OBD=II software is hardware specific. It will not work with other software. I have tried three different scanners and none will work with any other software than what it was designed for.

SR20DEN

iTrader: (7)

No we could have settled for that but it didn't even give us the error codes.
Are you using the universal adapter or the ISO specific one?

Jime

iTrader: (10)

Mine is the universal with all the interfaces.

Thats strange, so its detects a code and will erase it but will not give the error or error #?

2k2SEmax

Yeah, it detects that there is a stored error in the ECU however doesn't give the error code or number. Everything else works great except for this one thing. . I'm going to send an email to Mr. Harrison and see if he has any suggestions.

SR20DEN

Here is a list of most of the scanners I have found, including ones already suggested in this thread.

I am now considering the one from obd-2.com

krismax

iTrader: (15)

Also there is www.pocketlogger.com i have this one,can somebody answer a ? for me three of my fuel trims hover around 25% one stays around 0%, but o2 sensors seem fine around 0%.is this fine. Also when i put the pathfinder TB on my O2 sensors went to 27% lean ,my car bogged badly ,my scanner at idle was indicating a 40% increase in are flow. I took it of for now to try to figure out what to do . My car is not boosted but i drove it 300miles and it still didnt adjust

SR20DEN

iTrader: (7)

I wonder if it has to do with the relationship of the air flow vs. TPS voltage. Obviously it would be different. Or there is a vacuum leak or idle orifice open too much.

krismax

iTrader: (15)

Im sorry , i wasw asking this part of the paragraph in regards to my stock TB. The second part is about the pathfinder TB.

SR20DEN

iTrader: (7)

My answer pertained to the second question.

ilumo

Have you guys gotten good refersh rates? I have the autoenginuity data logger/scanner. It seems to have some nice options in terms of the software, but it seems to be VERY slow. Slow as in when you have to monitor 5-6 sensors simultaneously, you have to wait NEARLY 2 seconds for each sensor to retrieve data. I dont know if this is due to the sensors, the nature of the SERIAL rather than parallel interface, or if the ECU is just that SLOW. Its really annoying when you are doing a WOT run and the RPMs recorded are going, 1000,1500,2000,2500... thats missing a lot of data... Any ideas guys?
