-====== Engine Timing Table ======
+===== Measuring Timing =====
-This is the most complete timing number database that you will find for RC Nitro engines.
+If you want to know how to measure timing or want to time engines then see article: [[tellingtime|Telling Time]]
-Note: In obtaining this info there was modified timings as well. I consider this to be private information and im not willing to publicize someone elses private intellectual property. So any notes in relation to changes or what to do have been removed. I instead I tell you to do your own research and development. You will learn far more then you ever would copying. This site will only show engines that you can or could at the time buy off the shelf as stock or tuned by the factory.
-Special Thanks: 1st Racing Germany for the initial timing sheet off of their old website. Roelof Tooms of the Netherlands and Adam Blevins from the late AB Mods in USA for the timing numbers of all of the engines that came through their hands.

+===== Thanks =====
+Special Thanks goes to 1st Racing Germany for the initial timing sheet off of their old website. Roelof Tooms of the Netherlands. Roelof has been a valued and very contributing member on RCTech and has an elevated knowledge of these engines, and Adam Blevins from the late AB Mods in USA for the timing numbers of all of the engines that came through his hands.
+===== Important Note =====
 __//**The timing of the sleeve ports is only listed once, as these have the same degree opening and closing time anyway. Only the crankshaft opening and closing times are not symmetrical. In times where there is number+number then that means it is a multi port exhaust and the timings differ. The higher timing number is on the outer ports. Additionally if you see Boost and Timing have the same numbers its because they are the same. Differences in these started showing up in the late 90s/early 2000s engines.**//__
