I believe we actually talked about this that day and we had both cars do a couple of back-to-back pulls that would've allowed plenty of time to be out of the "cold start" time parameter.

I haven't exactly found my problem yet, but I just put some 24# injectors in to see if it clears up my low RPM WOT lean condition. So far it looks good, but I haven't gotten the MAF curve dialed in yet for the new injectors.... I guess we'll see how it goes after I get it street tuned.

Remember Blake.....the same thing happened to my 94 Cobra Vert later that day with the TwEECer...you might be on to something.

I think (don't quote me here) that 94+ cars are based on properly heated/switching O2's. In fact, they can switch to CL in a few seconds, from what I understand. I'm a little muddy, though, if that is 94+ or 96+...

The A9L OL to CL uses time as it's final factor. In other words, it won't go any longer than X seconds before the switch, but it doesn't HAVE to go X seconds. It can switch earlier than that...
