What are you using for datalogging? My cable doesn't work.

[tentacles]

Hi guys. Great site, congrats.

I bought a 1G DSm cable off ebay, and hooked it up to the laptop. I've tried 3 different datalogging programs, TMO, Tunerstein and Hand Held Halo, and all of them give me the same result:

- The connection is erratic, sometimes on sometimes not.
- The data doesn't come through properly, when the car is idle the RPM counter shows between 7000 rpm to 8000 rpm. It's clear it's getting *some* kind of data, but obviously not the right kind.

I emailed the fellow selling the cable, but since the cable is suppose to be for a DSM/GTO/Stealth, I can understand if he won't be much help. Any ideas here?

I use pocketlogger via a Palm M100 pocket PC thing that I picked up off ebay for £10.

I've never been able to get my early Evo to log using a laptop but it always connects first time and runs no problems whatsoever on the Palm.

However, for later Evo's I use a limitless cable and evoscan software

Forgot to mention it was a I (CD9A).

I guess I may have to buy a Palm then. Figures every time I try to save money and get by with less I always end up spending more. :rolleyes: I think I can still use this cable with a male-female adapter on the serial end, right?

[tentacles]

I'm exploring my options. Has anyone tried the Limitless USB cable for early Evos? I figure instead of any more mucking around with used palm pilots and adapters, might as well just get one of those instead?

[AndyF]

I should be able to test tomorrow both an openport2 and limitless cable with my E3, using Clanzers MUT monitor program as I've never been able to get any other program to log.

Will report back then

Ugh. SO I got a palm pilot and a null modem adaptor. Nothing. No connection at all with either pocketlogger or MMCd. What else do I need? DO I need a hotsync cable? I'm using the cradle right now.

silly question mate has the lead you've bought got a powered cable on it because otherwise it will not work mate..;)

[AndyF]

I've never managed to get any logging cable to work with a laptop on my E3 powered or not :( :(

tentacles,
I use the hotsync cable to connect between the palm and the cable because I've had no luck with null modem cables either

Andy

[soldave]

Remember reading elsewhere (it may have been from you Andy) that to use the logging cable with laptop you've got to switch 2 of the wires around. Can't be sure which ones but I think I read it on a DSM forum once.

[tentacles]

Yep, null modem adaptor, which I also now have.

As it turns out, the cable I bought was just no good. I think there are even some DSMs that don't like working with that particular kind. My pocketlogger cable arrived this week and now I've finally got the logging set up. Welp. Only took me 3 month of mucking around and $200.

Basically what I figure is that you need a cable with a seperate power connector. No seperate power connector == no work. Is that your experience as well?

Ran it for a bit, knocksum never goes above 1, and timing is advanced 30 degrees across the board. I guess that's good, since I was worried about the North American fuel not being knock resistant enough.

[tentacles]

Now I'm sort of worried. The knocksum fluctuates between 0 and 1 but never anything more than that, even when I am using 91 Octane AKI (95 RON). Is it suppose to be like this? The timing seems to be normal. Now I'm worried that i might have abad knock sensor.

Sorry Briggsyevo1, I didn't see your reply there for some reason. Cheers man.

[AndyF]

It does sound like a knackered knock sensor. If I were you I would get it checked out with a set of det cans as 30 degrees seems an awful lot of timing.

Have you checked that your base timing is set at 5 degrees? If your base timing is not set at 5 then the figures in the logger will potentially be not reading correctly in terms of timing.

Andy

[tentacles]

I'll check the base timing as soon as I get my hands on a timing light, but I have no reason to suspect it would be waaay off.

Here's an excerpt from the log, where I went up to about 4000 rpm. Does it look normal? I've obviously taken it all the way up to redline and the basic shape is the same for everything.

What is "normal" knocksum anyway? the pocketlogger site says timing is pulled when it gets to 7, but I've read elsewhere that it is actually 1/3 of a degree for every unit of knock?

[AndyF]

Any chance you can post a full throttle log up to the redline in 3rd or 4th gear as that will give a far better understanding of what is going on and if anything is wrong.

I know this is an old thread so I'm sorry for dredging it up, but is anyone aware that you can use technomotive datalogger with the early evo's and the right cable?

I've been using it for years as I never wanted to buy a palm just for logging.

This cable works perfectly fine for me datalogging with TMOlogger on the evo 1-3 and other Mistubishi's from that era. Here is the diagram of the cable I made and use:

[bspain]

Ok. I have now confirmed this cable also works with TunerPro RT for early Evo's. I'm working on a suitable Data Acquisition Definition file or adx file based off the 1g DSM adx file.

[bspain]

OK not sure how many are interested in logging on a laptop but here is some more information.

The diagram for the cable I listed above connects to a serial port but can be used with a USB to serial converter. I'm not sure if all USB to serial converters will work, some might not. The cable can be made up obviously with a diode and a resistor, a meter or 2 (probably 2m for convenience) of 2 core cable, a db9 serial connector and either small crimp connectors (suitable for the ALDL diagnostic port) or a mitsubishi 12 pin connector (suitable for the ALDL diagnostic port). Some basic soldering skills are required to put the thing together and probably some heatshrink for insulation.

For the mitsubishi connector like this:

http://dsmcables.com/images/aldlend.jpg

I found I could use the connector off a Mitusbishi factory electric Aerial (which is 14 pin) and just remove the excess 2 pins so it fits into the diagnostics port. Otherwise just use small crimp spade connectors and some carefull installation onto the diag port.

Basically you can wire it like this guy has and then run the resulting 2 wires to the ALDL end, one for data, pin 1, and the other to ground, pin 12, with a loop from pin 12 to pin 10 as well to set the ECU to diagnostic mode. I would look at using heatshrink over this stuff though, so there isn't any short's.

If you are not competant to put the cable together from this information then they are available from different places on the internet but are quite overpriced in my opinion and most are located in the USA. You can use the Palm cable with a null modem adapter if you know where to get one of those cables, maybe from ebay.com. I might look at making up cables for people if there is enough interest but I am in New Zealand so it might be a bit of a hassle for you guys.

I am also not responsible for any damage you might cause to your car if you do any of this. Although, I dont see how any damage can be caused by any of this. I have used the cable I made for 10 years without a problem.

Once you have made or acquired a cable then you need to plug it into the diagnostic ALDL connector under the dash next to the fuse box to the right of the steering column:

http://i43.tinypic.com/2hdw1uf.jpg



Pin 1 is in the bottom right corner of the connector. And pins 10 and 12 are in the upper left of the connector.

Then you can plug it into your laptop serial port or usb to serial converter and use Technomotive datalogger (TMOlogger) or Tunerpro to log the ecu parameters and get feed back from your tuning. More info on this part to come.

TMO datalogger is available here:

http://www.talon007.com/Talon/tmo/

or here:

http://1glink.com/Documents/Logging%20CD%202010%20%282%29.zip

BUT you are probably better off using Tuner Pro RT as that is what everyone here is tuning with... to use this all you need is the DSM 1G .adx definition file from the TunerPro website, but the Coolant, Intake and Exhaust Gas temperatures are calculated incorrectly for degrees F and also does not work out as degrees C either. I am working on sorting this out so we have a proper .adx file to use with our cars.

http://www.tunerpro.net/downloadBinDefs.htm


Instructions for use with TMO can be found here: http://www.vfaq.com/TMO/

To use TunerPro RT, click on Aquistion menu and then Load Definition file. Then find the .adx file and open it.
Then configure your cable by clicking on the Tools menu, then preferences.
In the popup window select the Data Acq./Emulation tab.
In the drop down list next to Interface type, select Use Plugin.
Then click on configure Plug-in Component, use standard serial and select your com port. You can try testing it if it is all plugged in and your ignition is set to on or if the engine is running.
Click ok and ok to close the windows back to the main window.
To log, select either Show Dash or Show Data list in the acquistion menu (or the red circle or yellow notepad in the top bar) and when your engine is running you should see data changing. Use the Record and Stop buttons on the top bar to record and stop.



There are some side effects of logging over the diagnostics port:

ABS

When a cable is plugged in it connects pin 10 to pin 12 (ground) which puts hte ECU in Diagnostics mode. While in this mode the ABS is disabled. This is due to the fact that the diagnostic pin for the ABS computer is tied to the ECU's diagnostic pin. It is impossible to put one in diagnostic mode without putting the other one into diagnostic mode as well.

The only way around this is to disconnect the ABS computer from the diagnostic line.

http://www.pocketlogger.com/instructions/abs_enable/

Setting the timing:

To set the timing, an underhood connector needs to be shorted. The problem arises when you try to set the timing when the cable is connected and ECU is in Diag mode. Having both the cable plugged in and the timing connector shorted, you are really telling the ECU that you want to set the idle. If you are trying to set base timing, be sure to disconnect the cable so the ECU is not in Diagnostic mode.

[AndyF]

All looks and sounds very good. I still use my pocketlogger for logging on my E3 but it's good to hear that other alternatives are around and it'll be even better if you can get the full adx file for tunerpro sorted as that allows you to log and tune in a single package then.

Good work

Andy

[Padders]

Arrr Andy where have you been hiding?! lol

How's tricks?

[bspain]

Here's an example of me logging my car with my customized adx file in TunerPro RT. I'm only logging the RPM, Knock Count, Coolant Temperature and Intake Temperature to keep the sample rate from slowing too much. Also because I'm trying to get the temperature calculations sorted. So ignore the fact the rest of the parameters arent doing anything.
