I have seen mention of a few different data logging options in my reading of this forum and would like to aggregate all of the choices into one thread if possible.

I know I'm missing some options, but right now I can find mention of:

PC-based solutions
- Autotap http://www.autotap.com/productcat.asp?topLevelid=36
- AutoEnginuity http://www.autoenginuity.com/products.html
- Ease http://www.obd2.com/scantool/scantool.htm

Standalone device options
- Race-Technology DL1 http://www.race-technology.com/data_loggers_8_920.html
- Car Chip http://www.carchip.com/
- Scan Gauge II http://www.scangauge.com/

What else is out there?

I'm especially interested right now in logging IAT in order to determine the current efficacy of the stock I/C cooling system and then the improvements made by replacing the pump and then the Heat Exchanger.

Any comments on any of these? Do they all log with a high enough frequency to be useful?

I think I'm leaning towards scan gauge or autotap ...

Great topic, I started a similar one on the W211 board. We can always use more information on scanners, loggers, programmers.

I think most people use the Lap top based solutions, and I see AutoEnginuity and Autotap posted here most.

Agree that more info is always good. E55 owners need better diagnostic/logging tools so they can know what's going on with the car. This takes the power out of the dealerships' hands which is always a good thing. I'm still really surprised that no tuner has perfected the ECU tuning for a pulley swap. I would have thought they could crack the code to change fueling parameters to make AFR at around 12.0. I really feel that the pullied guys are leaving A LOT of horsepower on the table. I keep hearing how the pulley causes the ECU to dump fuel so the AFR is between 10.5-11.5. I'm waiting for someone to come out with a solution for that.

DO NOT I REPEAT DO NOT GET AN AUTOTAP!!!

I HAVE TRIED DOZENS OF TIMES AND MANY CALLS TO THE COMPANY AND CAN NOT GET AUTOTAP VIA USB TO PC, TO SAMPLE MORE THAN ONCE EVERY FEW SECONDS.

When you are pushing 700hp. Runs only last 10-15 secs tops on highways so you do the math. Not many samples to choose from.

Tried every config on the planet and just gonna hock it on Ebay and go with something else.

Lemme know what you go with. Heard good stuff on Nology. ???

So, which is best and what vendor do you all like?

Wow OK, so I think I got the message on autotap

What about the ScanGuage II ... does it record fast enough to be useful? And can you export the data at all from the device to a laptop?

I am looking into getting this unit:

Seems like a pretty slick device and I didn't want the hassle of packing the laptop with me when I go out for a run.

Jakpro1

Auto Enginuity seems to be a pretty popular choice around here.

Also heard some great things on Nology



Launch X431 seemed nice til I checked the price, OUCH!!

Anyone else, please please chime in. I wanna purchase one ASAP too.

Thanks again.

Sorry for freaking on the Autotap. Just hate it so much and this was my first chance to tell someone of the nightmare it has been.

I just bought an autoenginuity that should be here Thursday. It seems to be the choice around here. Not very expensive either.

Just an FYI...

The sampling rate on all the OBDII scanners is about the same.. its a limitation of the OBDII spec and the amount of data that it can transfer.

I've been using Autotap for a long time on alot of different cars.. when I got it for the Merc it had some problems.. they released a firmware update to 3.51 to add better support for CAN bus and it improved..

I haven't used Nology or AutoEnginuity so I cant comment on them, but as far as sampling rate, dont expect anything better from them. My $0.02.

vrus

If you want something that samples better, you need to move away from OBDII...

This is the one I have been researching for a while.. I am going to try one out..

This one is really popular with the Porsche guys. It seems to almost be a standard they use to compare their runs.. I was going to get one for my 993TT http://www.race-technology.com/ax22_8_938.html

FLSL55

Any update?

Looking for a scan tool that will work with an 03 SL55. I don't want to pay more than $200.

Figures you would start a thread with the very same question as me Josh ....4 years later bump

Innovate Wifi with logs works connected to a LC1 wideband to monitor AFR
Connect you're iPhone or Android and you're done

nanayaw6

Grant, do you happen to have a screenshot of the gauges and also a link to the android log works? I only see iPhones on their site

mbelite1

I used the OT-2 (Innovative Wifi) on my iPhone and I loved it. Easy to log passes and monitor stuff. I changed to the DashDAQ because I wanted something more permanent, so I will be selling my OT-2 if your interested. Pm me!

I can screen shot it on my iPhone when I get home tonight.
The screens look similar to their website though http://www.ot-2.com/

I misspoke on the availability of the Android app. It was due for release in January but I guess it's still not available. There is a way to make it work with TORQUE for Android though. http://www.innovatemotorsports.com/f...6&postcount=15

The Logworks PC based reader is great for analysis and identifying issues and isolating issues by channel.

I use a PCS datalogger in my car. It is very high speed and serial interfaces with the lc-1 o2 sensor. You can just piggy back the analog signals from the ecu that you want. It is very fast and has a fantastic log viewer to download to your laptop. It will store and playback on the unit also. As said if you are not logging off the CAN bus or directly from the sensors it is to slow from the obd port. You can also tap your frt and rear speed sensor data for wheel spin and vehicle speed inputs. 100hz sample rate. 25hz from the serial interface. It also has GPS add on and other devices like 8 channel egt module.

BTW DashCommand is available for the Android and they state they support OT-2 by Innovate. I'm going to download it on my iPhone tonight and test it out.

Dashdaq with Zeitronix works for me.

Does anyone using a Dashdaq monitor IDC? If so, what wire did you tap into for the user signal?
