 RPM Limit on MSD I have installed an MSD 6AL Digital Box on my 911 S 1970 engine. What RPM Limit setting should I choose ? | 
| 
 What does the redline on the tach say?  I would set it around there. Assuming car is bone stock because you have no other info present. | 
| 
 I found that mine is 200rpm out so is set to 6400, but cuts out at 6200 , the msd is a very soft limiter. I'm use to Bee-R limiters which are very harsh. |

 I have a Daytona-Sensors CD1 CDI on my 1973 2.7 and the redline is supposed to be 7200.  I have the soft rev limiter on the CDI set to 6600 RPM.  It is fun to run up against it and feel the engine go soft. |
