We're still trying to figure out what's going on with the new I/H strategy. Most trucks seem to respond favorably with the new hybrid strategies but there are still a few trucks that have a cold start issue. The only conclusion I can come to is that the stiction problem on those few vehicles is so bad that only the aggressive I/H strategy will fix the cold start problems. Unfortunately, we already know that the aggressive I/H strategy will mean the demise of the FICM circuitry so it's an option we reserve for only the most extreme cases. If the cold starts are that bad, that's about all we can do.

Windows™ Vista and Windows™ 8 is a pain in my a$$!
Windows™ 10 is only slightly less annoying!
Windows™ 11 is garbage!
