Ok, I have a question regarding datalogging by IX. I have a friend who has a AP, which comes with the obd-II cable. Can I use this cable to log my IX via a free datalogging program such as Tari Racing?

Well I use obdguage, which works pretty well for me, I was unable to get palmenstein to work. In obdguage, there are only 2 connections you can use. The multiplexengineering.com cable, and the elm connection. There are specific settings for the cable in the preferences menu. If the software supports the cable it should be listed, if not listed probably wont support it.

 

What exactly is an AP??? The only Ap I know of is a COBB AccessPort, which is for subarus, so it wont work.

 

yeah an access port. The AP has an obd-II cable that goes into the access port via an rj45 jack. Both Suby and Mitsu are ISO I believe, so I was wondering if the cable could be used to log with via a variety of different programs. The actual Accesport tuning box is not in the equation.

Well, first off the AP doesn't datalog. I used to have one. It might datalog if you have the StreetTuner or Protuner, but I don't think so. The cable might work..
Download a demo of a OBD datalogger for a PC
use a laptop,the cable and the software and you might be able to make it work.

Again, I say might.
And also, the OBD system's sample rate is really slow, I think 6 samples per sec, which isn't good. You want at least 64 samples a sec or more.

 

I wanted to use the cable, laptop and program. I understand the AP doesn't log, just want to use the cable thats all. Any good solutions for a faster sample per second? This way would all be free to me, just want to check out some things for ****s and giggles.

Some OBD logging software manages to "overclock" the sampling rate. IIRC, the max sampling rate I saw claimed on an Evo VIII ECU was ~20 samples/sec. Not sure what the IX ECU can handle.

Your cable may or may not work with other software. A lot of it depends on if the cable has a built in OBD-II to serial conversion, or if the conversion took place in the AP.

sampling that fast is not going to be that critical for the few things you can take off the stock wiring. and why 64 hz? that is a pretty odd number for sample rates.


if you really want to record data, go buy a DAQ box. there are many companys that make them. even the zeitronix ZT-2 wideband has a few user inputs plus major engine parameters that can be logged to the PC.

for things like wide band sensors, there is a good bit of latency of the sensor, and it takes a good eye/knowledge to understand this and correct for it. sampling faster wont correct it in this case...

 

Just buy a kit, its much easier than trying to figure it all from scratch....Oh, i got mine from obdloggers.com , works good.

 

think i'll purchase a kit from them too....does it include palm pilot too?

 

Try it out, maybe it'll work.

 

I am gonna try it this weekend when we log my friends subby. Like I said, it will not cost me a dime, just my time. Can't hurt to try I guess.

I am mainly interested in logging timing to compare the different temperatures outside and different brands of gas. Just want to see if everything is cool since I was tuned in cooler temperatures. More of a research kind of thing, not something I want to invest alot of money into at this point.

The guy my friend bought the AP from (TSD?) said to download a free logging program and use the CABLE (minus the AP) to log with. Don't know if that helps any? I do know the cable has a box like thing on the obd connector side.

Sounds like it might work, although you'll still need to figure out a couple of things:
1.) Need to get/build an RJ-45 to serial adapter (you may have to a bit of experimentation with the pin-outs)
2.) Download some logging programs and see if they work.

If you have a pic of the cable, we might be able to figure out if it is a known kind, or if it's proprietary.
