Not sure why everything thinks I have cats. It's a 3" off road pipe into the stock catback.

Anyways, I don't know why it isn't locking up because I can manually command lockup with my bidirectional controls on EFI live. So for some reason the PCM isn't commanding lockup. It will lockup like 2-3 minutes after you've been cruising on the highway.

As well, Krambo's idle sticky is pretty decent considering it's generic. It starts up good now and hold idle, but it's bad when coming to stops, it wants to die. So I'll need to work on that.

Getting any missfires? They unlock the torque converter and will cause it not to lock

Yeah I had the SES light flashing but I just turned it off. I think you may be up to something there.

Aren't false misfire codes common with cam swaps? I'll bump up the misfire minimum RPM threshold and see if that does the trick. I'll try and get an idle vid tomorrow too.

+1, this is what I was going to post up, I'll bet that the PCM is detecting misfires, which may be false due to the cam

If the tq.conv. won't lock cause it detects misfires, after a cam swap, if that's what happening, what's the cure?
Done thru tranny tables or somewhere else in tuning? Or both?

sorry jeezz, when you say catback it usually means it is behind the cat.
