I've only tried it on the 7.4 and 5.7L trucks. Both did the learn as soon as it hit 4250 rpm which is the cutout in neutral. It took me longer to find the prceedure in the scan tool than to actually do it. Next time you do the relearn on one snap the throttle and let off just as the RPM crosses the cutout threshold. It should get the relearn immediately. As I recall the learn actually happens on the decel from the snap. Which is why it would take longer bouncing off the rpm limiter.
