I have been searching through the site and have enjoyed all the great info concerning tuning. I have a 91 firebird with the 8746 ECM. I am using WinALDL to log data. Were does the injector pulse width show up in the logged data? I have looked and can not find it. I am sure am doing something wrong,, I just can't find what it is. I think my injector are going static but I am not sure since I can't find the data in the log. Thanks for any help.

 

I don't believe you will find injector PW in winaldl. It is just a progam to record data from your ecm so you can compare and make changes in whatever other software you are using to modify you Bin. I hope this helps a little bit. Winaldl logs error codes, BLM's , raw data, sensor info, knock , o2 sensor. BPW is a combination of alot or I should say a very long math equation done by the ECM. If you stay on the stickys you will find it. Alot of great info here on TGO! GL!

 

The PW and SA can be patched inot the ALDL data stream. Over on the TBI board, in the stickies is a thread about tuning. I believe that information is in that thread. If not check the stickes above for the tuning guide book in the 8063/8746/7747 section.

I didn't realize those things could be seen in Winaldl. I will follow up the suggested reading for sure. Thanks RBob
