rodan Posted October 28, 2005 Share Posted October 28, 2005 Anyone know the possible values for Ignition Advance Modifier? Link to comment Share on other sites More sharing options...
KGreb Posted October 29, 2005 Share Posted October 29, 2005 Anyone know the possible values for Ignition Advance Modifier? Possible values are 0.0 - 1.0, with 0.50 being the value at ECU reset. Finding the addresses and figuring out the data representations are the tricky part. I've been testing a couple of things for Calvin and I suspect you'll see at least partial IAM support on the next release. Link to comment Share on other sites More sharing options...
rodan Posted October 29, 2005 Share Posted October 29, 2005 Thx - I'm using Delta Dash, so I'm already getting IAM... Link to comment Share on other sites More sharing options...
SeeeeeYa Posted November 7, 2005 Share Posted November 7, 2005 Being extremely interested in datalogging the OBD-II port, and having the AP cable and a laptop, I have researched the subject and find that virtually every reference called for a HARDWARE INTERFACE, except for this forum. As stated by one site, "ISO, however, is a Godsend. This is because it uses a data-format that a standard PC UART can deal with, the only thing you need to do is to convert the RS232 voltage levels of the PC into the 12V OBD-II levels of the ECU interface." Before I either muck up my laptop or my car's ECU can anyone comment, preferably about personal experience. Link to comment Share on other sites More sharing options...
edmundu Posted November 7, 2005 Share Posted November 7, 2005 SeeeeeYa, Since you have the necessary hardware, all you need is the Tari Logging software, available for free here! With it you can log, and then using DeltaDash demo, you can view your logs in a easy to read graphical format!  Also, if you only have USB ports on the laptop, you will need to pick up a USB to serial converter...

SeeeeeYa Posted November 7, 2005 Share Posted November 7, 2005 Thanks for the reply edmundo. My Vaio only has USBs so I did get the required USB to serial adaptor. However, and pardon my ignorance here, I don't know what "DeltaDash demo" refers to. Please educate me. Link to comment Share on other sites More sharing options...
SeeeeeYa Posted November 7, 2005 Share Posted November 7, 2005 OK. OK. Got it. Since I have the AccessPORT I was not aware that DeltaDash was EcuTeK's software. Downloaded the demo version. And after rereading your post I understand. Thanks. Now all I have to do is give it a go! Anticipation.... Link to comment Share on other sites More sharing options...

And after rereading your post I understand. Thanks. Now all I have to do is give it a go! Anticipation.... hope you're all cleared up on things.... Technically you dont need the delta dash software to view the logs.. but it can graphically display things which may make it a bit easier to understand.   but other than that, sounds like you've got the gist of things. Just plug the AP cable up the car, plug the other end to your usb/serial adapter and then to your laptop... then just fire up the TARI software and start logging.

KGreb Posted November 10, 2005 Share Posted November 10, 2005 For those who are interested, a new version of ECU Explorer is available on the Tari boards. I have verified that it reads load and IAM properly on a 2005 LGT, AJ17A ECU code. Link to comment Share on other sites More sharing options...

MarcusDubya77 Posted November 10, 2005 Share Posted November 10, 2005 i could really use this info..i downloaded the logger and couldn't get anywhere after that...great write up :woowoo:check out the Diamond Gray Metallic Monster!!! Link to comment Share on other sites More sharing options...
KGreb Posted November 10, 2005 Share Posted November 10, 2005 Another note - new release available (1.0.74) this morning that is supposed to fix the lockups some users see when datalogging multiple data items. This seems to be most common with the Cobb AP cable. Link to the relase notes - http://www.tari.co.za/cgi-bin/yabb2/YaBB.pl?num=1131613339/. Note that you may need to be logged in to the TARI forum to download the software. Link to comment Share on other sites More sharing options...
wms291 Posted November 16, 2005 Share Posted November 16, 2005 With a LGT should I see positive or negative value for IAM? At idle I have -15.98 at point OXFF2688. Link to comment Share on other sites More sharing options...
edmundu Posted November 17, 2005 Share Posted November 17, 2005 With a LGT should I see positive or negative value for IAM? At idle I have -15.98 at point OXFF2688. Not the right address! You should be seeing a max value = 1 If you do a reset, it will start at 0.5, and then should jump up to 0.7 rather quickly, then after hitting boost for a few seconds, it should max at 1 What is EcuExplorer reading your ECU version? Try FF267C, this one works for mine. Link to comment Share on other sites More sharing options...
wms291 Posted November 17, 2005 Share Posted November 17, 2005 Another thanks to edmundu. I'll check the other addresses in the morning and try the reset. Link to comment Share on other sites More sharing options...
KGreb Posted November 17, 2005 Share Posted November 17, 2005 The addresses for load and IAM vary per ECU type. The ECU type will be listed in the left pane of ECU Explorer when connected. This is also printed on the label on your ECU case, but may be changed if you are reflashed. AJ17A: IAM = 0xFF2688, load = 0xFF50B0 early '05 LGT AJ17B: IAM = 0xFF267C, load = 0xFF50B0 late '05 LGT AJ17C: ??? anti stuttering reflash TSB for '05 LGT Link to comment Share on other sites More sharing options...
wms291 Posted November 17, 2005 Share Posted November 17, 2005 267C worked for me. Link to comment Share on other sites More sharing options...
edmundu Posted November 17, 2005 Share Posted November 17, 2005 267C worked for me. Nice! Now go log some data and report back! I like to see MAF grams/s values, besides the usual suspects. Link to comment Share on other sites More sharing options...
wms291 Posted November 17, 2005 Share Posted November 17, 2005 I have to borrow a laptop from work but a least I can always load the program there. This hopefully will lead to some map sharing. That's why I snagged the laptop. Another member got a tune from the same tuner I used and got 20 ft-lbs more. So I got the map and logged it. Knock, AFR, IAM and boost all look good. I also monitored EGT but they were a constant value. Then it kicked in. I forgot I pulled the probe. Link to comment Share on other sites More sharing options...

f1anatic Posted November 18, 2005 Share Posted November 18, 2005 How do you log these Dynamic Advance and Dynamic Advance Multiplier Thanks. Link to comment Share on other sites More sharing options...
KGreb Posted November 18, 2005 Share Posted November 18, 2005 Dynamic advance multiplier is the updated name for IAM (ignition advance multiplier) on the 2004+ ECUs. Not sure what you are seeing defined as dynamic advance but you can log total ignition advance as well as knock correction which should give a good picture of timing.

SeeeeeYa Posted December 13, 2005 Share Posted December 13, 2005 Time has passed, and I have finally logged some data. After getting the Belkin USB to serial cable driver software installed, installing the latest ecuExplorer software, securing my AP cable with duct tape and my Vaio with the seatbelt I set off to log some data. Success. However, because I wanted to compare my data with results from others I found no way to use the .pdf files everyone uses to share their data here. Simply renaming .pdf files to .csv, obviously, doesn't work. And, file converters do not work because, it seems to me, the files were altered by the initial csv to pdf conversion therefore, etc. Where am I going wrong here. I'd like to both share some of my logs as well as compare data. So far I don't really like what I see but am unable to determine if it is 'normal'. Certainly, based on various information I've gleaned from our own forums as well as others I question both data values I have logged as well as my car's performance. Until I am sure the data captured is correct I cannot address the car. I will say this: as has been reported I notice a significant increase in performance after a reset with a gradual softening of that performance over time. After reviewing my datalogs I see what I interpret as reasons why; timing being retarded. On the other hand I have looked at the raw data from pdf files on the formum and it appears my results are similar????! Link to comment Share on other sites More sharing options...
rodan Posted December 14, 2005 Share Posted December 14, 2005 I think you can post your logs as .csv files here and everyone will be able to read them. Link to comment Share on other sites More sharing options...
