I was just curious about the timing. I'm pretty sure that if Mark had worked a BIN file and the timing was changed in it, then he would have told you to verify your base timing to match the BIN file.

Seems odd that you'd have to resort to doing this for something that automatically controlled if all your sensors and ECM is good.

Here is something you might want to read through. (beware that some pages are out of order).
