When will this here come out? I am especially interested in the AFR since I do not have a wideband yet.

So I just got my OpenPort (tactrix) cable today. I installed Tari DL1 and it seems to work great. I haven't gone out and done any logging yet, just turned the car on and saw it was getting data. I have a 2000 outback sport, btw. I'm going to try this on my 99 L wagon later...

Anyway, I'm looking forward to when this software will be able to read trouble codes. Need any help coding that up?

In the mean time, is there any free software out there that can read and clear trouble codes using the tactrix cable? So far all I've found is freediag (http://freediag.sourceforge.net/), and that only runs in linux. (not that there's anything wrong with linux, I just don't have it on my laptop... yet...) And the other software out there seems to only work with the elmscan cables.

Thanks for the great software.

Calvin, keep up the great work. Your program makes good logging available to the masses - not just the lucky few with UTECs or Deltadash.

i'm still working out the addresses for the reading of trouble codes. will get there soon...

clearing them is a simple ecu reset. very easy so add that to the feature list of v1.0.41

i think this is just the start, with the initiatives of openecu.org the ability for others to do this kind of thing is getting easier so it shouldnt be long before there is a wide range to choose from across all platforms. my aim is to have a really good app that covers all the functions of the ecu from logging to flashing, and hopefuly people will keep on using it even if there is other stuff available.

doesn't lambda work the opposite? > 1 is rich but < 1 is lean. maybe thats what threw the conversions out?

so as long as our knock correction readings are not negative...then we are not seeing knock?

is that how it goes?

my last log saw 0 min and 7 max

also...anyone else seeing the lambda stay around .7578125...mine stayed there from 3000 all the way to redline

Greater than 1 is lean and less than 1 is rich.

calvin.
Since AFR=lambda*14.7, a lambda <1 would give you an AFR <14.7=rich, and a value >1 would = >14.7 = lean.

BTW, you didn't forget about fuel flow did you? I'd like to see instant MPG values, now that you got the vehicle speed fixed.

0.757Lambda = 11.13:1 AFR... that is the richest the stock front O2 sensor will read.

DO NOT use this value to tune, as wideband sensors are not accurate under pressure (e.g. high pre-turbo exhaust pressure).

Default TARI Racing Software FORUM is up and running...

i finally managed to get the TARI Forum working. so we can move our discussions across there and stop adding to this ever increasing thread.

go to it from here (www.tari.co.za/cgi-bin/yabb2/YaBB.pl), as i havent updated the TARI main menu yet.

its a brand new forum so i havent created any groups/topics yet. it is a free forum from YaBB (Yet another Bulletin Board) so login, see if you can register and make a post in the 'test' section.

tomorrow i'll add some groups and we can get on with it.

Ha! I was the first poster! This will be easier to keep the threads/info in one place, but not help me at all on my quest to rid myself of my newbie status and get "specialist" status.

Thanks for this post. I have a MY00 Forester and a MY01 Outback Limited Sedan. I still need to buy the cable and was wondering if this would work. Which cable did you get, generic or wrx?

I'm also wondering about the code and code clearing software. Did you find any?

As for Calvin perhaps we could just ship beer to his home. I'm sure there's a local distributor/brewery that would be happy to do that. Plus he wouldn't have to wait for if/when he came here.

I bought the generic cable. It has one pin missing (#14 I think) compared to the WRX version. I read that that pin is used to supply voltage for reflashing WRX ECUs. I don't know if the existence of that pin would cause any problems on a non-WRX subaru, but I didn't see any WRXs in my future so I just played it safe...

I have not yet found any other software that will work with this cable that reads the diagnostic codes. The other free software I've tried have given errors saying it can't open device or find the correct interface. For example, scantool.net has some free software, but the cable they sell uses different pins than the OpenPort cable. They are also using an ELM 323 chip, which may futz with the data from the ecu before sending it to the software.

I am going to try freediag next (freediag.sourceforge.net). Hopefully I can get it to work on a slax cd or something. I was also looking at their source code to see how hard it would be to finish porting it to windows. Some of the os abstraction has been done, but it looks like it's still using linux specific serial functions.

I have the same question about the knock correction readings as Mosquito16.
I went out and gave the program a little test and saw a 0 min and 1 max.
Does this mean that I had one episode of detonation?

Thanks,

Don

I don't think so. KC usually scales from negative values to positive, with negative usually being low single digits, and positives going all the way up to 12+.

How far the KC gets depends on the current IAM value as well as how much KC authority the map you are running allows at that load/RPM point.

I'm not sure that the logger always logs KC correctly, I have seen a couple logs from it where the KC has ranged between 0-1 which would be very abnormal.

he is talking about the digital signal...it will only show 0 or 1...you are talking about the knock correction in terms of degrees (analog)

OK, so if Don was looking at the Knock Sensor signal, all you can tell from it is whether or not the ECU is seeing knock when you happened to sample it. So if it hit 1, the ECU picked up some knock.

Well, I hope it's not detonation.
I'm running Cobb Stg 2 93 oct map w/ gutted stock up-pipe, TXS turboback, K&N filter, ported and polished TB, Walbro FP. I usually run Sunoco or Shell 93
I've had another problem w/ stg 2 running really high >1600 F egt's during track day's. But after flashing their current stg 2 map the egt's do not get above 1500 which is still a little high.
When I called Cobb about the high egt's I did not get much help.
That's why I'm hoping it's not knock.

Yeah, I've also recorded a 1.390625 right after I lift off the gas. Is this too lean?

Edit: Btw, this program is way cool. Awesome job calvin.

Lean conditions like that is normal when you lift off the gas. This is normal with all vehicles.

And just to be clear - the tactrix cable is USB, and Cobb cable is serial.
If your laptop only supports one or the other, this may be an issue for you.

Although note that the free tool to download the ROM image to your computer appears to currently require an unusual baud rate and may not work with the Cobb cable (I'm not certain).

The thread discussing that tool is here:
