They sell others at similar prices that adjust rate, but do not really limit total advance. Sleeving the pin with tubing would reduce the total some, but not by a lot. You would have to get more ingenious to reduce it down to, say 10*.

They sell Accel and Moroso units at around $40 that claim to adjust the total advance with the same rate adjustment, but the reviews seem to indicate they do not work as claimed.

You have to fabricate an independent limiter, the same as with the $14 HEI advance units.
