So i got the ALDL- USB cable and the TTS datamaster program and i neen to know what a few things mean. What in the hell is the "COP2<52 ms"??? ive been looking and looking but nothing.
Also i noticed the spark advance at idle was all over the place jagged like.

thanks

I can answer the second part... the reason for the erratic spark timing is that the ECM is making adjustments to the timing to keep idle speed steady. There's a table within the $8D calibration that can zero this adjustment out if you wish.

 

I JUST FOUND OUT!!!!


Computer Operating Properly- <52mS between falling edes refers to this, when the clock signal jumps from high to low, it is called a falling edge, when it takes Less than 52 mS to do this it Tells the computer that it is operating properly.


I think.


By all means correct me if I am wrong, i just have been doing google searches and sitting on Wiki for a half hour trying to firgure what it means. and that is what i got out of it.
