What do I need to get in order to record engine parameters during quarter mile runs for my 95 Maxima? I want to be able to record engine timing, rpm, mass airflow sensor voltage, throttle position sensor voltage and wideband O2 sensor output.

Any recommendations?

Problem is the amount of info you looking to datalog. I know my Harrison OBDII can do 4points of logging, so I can knock out engine timing, rpm, MAF, and TPS. The wb02 will be done with the wideband logging, but then you would need two laptops or two serial connections since they both use serial.

Then again, the eManage can do all that logging and then you can use the wbo2 for the a/f logging side.

It gets complicated.

E-manage can do datalogging? I'd get it just for that, then.

I am using a http://techedge.com.au/ . It records RPM, Wideband O2 and EGT so far. It has other inputs I just haven't gotten around to trying them out or hooking up. My main interest is the A/F and RPM logging the others are just nice to have.

My OBD Scan http://www.ghg.net/dharrison/ will also log timing, coolant temp, voltage, RPM, intake air temp, air flow, O2 sensor voltage, load, fuel trim, speed etc etc, all that your OBDII handles.

The S-AFCII will show RPM, throttle position, battery voltage, airflow, correction etc.

However there is nothing I am aware of that will do all of the critical ones I would like. My plan is to run two logging programs, one from the wideband and one from the OBD Scan and cross refer the readings using the RPM as a reference.

My belief is that the wideband is the most critical of all, running any form of boost, the rest hopefully will just confirm that if your A/F is correct your timing, egt etc will be in proper proportion.

It actually can log a rack of stuff, like 10samples/sec as well, not like my harrison obdii which only gets one like every 2secs.

I think it can log more than 4things as well.

Gotta love the Excel export function...

WOW, steve thats sweet!!! The perfect tool for the Dyno Master

If you want to do wideband O2 output as you indicated, then you are going to have to get a wideband unit and sensor. Neither E-Manage nor any of the OBDII readers have that capability.

Wideband O2 readers are the only way of displaying an accurate A/F over the range which is necessary for boosted engines.

Narrow band sensors are more of a rich/lean sensor, a wideband will tell you HOW rich or HOW lean you really are so you can tune the A/F accurately.

Also tuning on the track is more accurate than on a Dyno. A Dyno doesn't load the engine the same way as a WOT run down the track which is why you are doing this I presume.

Of course monitoring the timing, temp, throttle opening etc is great stuff but without a WBo2 and a way to adjust A/F (ie e-mange, S-AFC etc) you are just playing.

I just got my Auterra this week and like it so far. Kinda tough changing params on the fly and I wish it could sample more than 5 at a time. Neat stuff anyway.

Hey, does it work with laptops as well?

[QUOTE=Phatmax98]does it work on 95maximas? :|

I think I can answer that, I looked on that auterra website and it said 96 and higher, so I don't know for sure..look for the OBDI or OBDII system, I think those might work.

Im in the process of going turbo so Im looking for a data logger. Does anyone have any others to add? I plan to go with an Emanage Ultimate which has logging capabilities but will it log everything a OBDII logger can?

Jime

iTrader: (10)

They are for completely different functions. The EU will log but only functions related to tuning, ie water temp, timing, intake temp.

The OBDII will give all the others as well as errors and reset CEL. Although I have an OBDII reader and do like it the Consult clones give more functions and connect to the consult port. They also let you turn fans on and off, change timing etc but only while the engine is running it resets after you shut if off. I also like the 0-60, 0-100 etc timing runs that automatically start when the car starts to move.

The best part is that it only cost me $108 including software. They will not work on Consult II ie 5th Gen only the grey port Consult 1 ports.

You can check them out here.

Thanks jime! Im probably going to go with that Consult cone then. Does your OBDII reader give any more data the the Consult does?

Also, advancing the timing will work but it just resets?

Jime

iTrader: (10)

More stuff from the Consult and I haven't tried the timing yet but from what I read it resets when you shut the car off.

Also if you want get it without software and I will send you the 2 I bought.

Just make sure you have the grey consult port in where the fuses are under the dash. I have heard of some guys not being able to get it to work on some later 4th Gen models.

I do have the grey consult port, to the right of the fuses, hopfully it will work on my 98, maybe its just the 99s that have the problems. Did the later maximas just not have the grey port or was it just the ecus?

I sent them an email to see if they have it available, hope they get back to me soon. For the software that sounds good, I'll Paypal you some money for them. Thanks Jime.

All 95's are ODBII.

Does EU just log timing adjustments or actual timing? I know EU won't log actual timing unless we get it working with our Crank and cam position sensors.

No all 95s are NOT OBDII, jaimecbr900 95 Red maxima is OBDI not OBDII
