We have a full line of profiles that we have developed for both 3 and 5 chain engines. We have learned to only apply them in the situations where we can match the cylinder heads to the camshaft profiles, at minimum. That means that they typically only see service on our complete engines.

These engine and ECUs are odd about changing camshaft timing events, things like terminal CELs and the like are often found when making camshaft changes. Our experience while developing our own profiles in house has been focused on cams that will allow the engine to still pass an emissions test, which is challenging to say the least.
