Programming Stuff - BLM's, PE mode, SVO injector settings in Tunercat

Just thought Id let everyone know this info I found on tunercat and also on BLM's and PE mode

http://para.noid.org/~lj/
EDIT: Sorry here is a link to the PCM section of his page:
http://para.noid.org/~lj/PCM%20Tutorial/PCMtutorial.htm

Scroll to the very bottom, I read this quote:

Quote:

the PCM calibration is generally good (BLMs near 128), or generally rich (BLMs are smaller than 128), the PCM will set the BLMs to 128 during during power enrichment (even if it was 108). But if the last BLM before the switch to power enrichment was 132 or bigger to compensate for the calibration being too lean, the PCM will use that BLM during WOT instead of 128, even if it's 160. GM did not want to let the engine go lean when you dip into the power! (see the Split BLMs page)

This is something I've heard talked about wrong all the time! Some people have complained that their WOT was affected by Bad O2's yet other said that the O2's arent used at WOT. But what really happens is the cell before WOT gets thrown off by the bad O2's and if the cars reporting itself as "lean" then it'll use the last cell's BLM at WOT instead!

Finally, if anyones followed my last few injector SVO question threads I found a link with how to program the computer for the Ford SVO's using tunercat

Hope someone finds this useful. Time for me to hit the sack...
