I have been using Rcxel sensors for years. Just like any company today they might have vendor problems. They are not "known to be useless". Known to be useless is a pretty hard phrase.

I have bought hall effect ICs sensors from electronics stores and made my own years ago. But lately I use those being discussed in this thread. The only problems I have had was with a batch of CRRC Pro sensors that the + and signal wires were crossed, lucky me that cost a handful of hair I couldn't afford.

You should know though that bcchi is the founder of C&H Ignitions and has been involved in the development of almost all the ignitions being discussed here.

Unless you have the ability to check the spark @ RPM this method of timing shows you the timing at full advance. Inside the module a calculation of low RPM retards the subsequent sparks until a RPM that changes the calculation is reached. My meaning here is that unless you see the running at 2000 rpm timing at 4 degrees and the 8000 rpm at 46 degrees the timing that you see in a single slow counterclockwise rotation may be misleading. I no longer have an Oscilloscope to check these points.

I believe this thread maybe going on to long for a sticky unless more technical data is added so that no misinformation is presented that might permanently damage one company.
