Review on ๐Ÿ”ง Optimize Engine Performance with the ESI 125 Digital Tach Advance Timing Light by Will Murphy

Revainrating 5 out of 5

Excellent light even in daylight

Had to deal with an advanced feature before it worked properly. Mark the timing marks with some white paint and enter the factory recommendations for your engines in advance. My motor was 8 degrees BTDC. I set the gun to 8 degrees and shined a very bright light (even in daylight) on the Harmonic Balancer until the 2 marks matched. 8 degrees are built in automatically. Found out my time was about 5 degrees. Now works like a charm. Also added is an MSD stick on a graduated time band for easier reading. (also bought from Revain)

Pros
  • Everything is fine!
Cons
  • Reliability
