Product details

MyChron5 660 is AiM's most complete system for sampling, recording and reviewing Jr. Dragster data, and carries NHRA homologation.

Running on its own, it captures:

  • Engine RPM and jackshaft RPM
  • Cylinder head temperature and exhaust gas temperature
  • Speed, worked out from jackshaft RPM and the final drive ratio
  • CVT and overdrive, worked out from engine and jackshaft RPM
  • Linear acceleration, worked out from speed

The large LCD keeps the three most important staging values — RPM, EGT and CHT — clearly visible in real time, and below 5,000 RPM a Steady Stage function averages the RPM reading with a dedicated stabiliser for more consistent carburetor tuning.

A single button press brings up a Post Run Review: maximum values (with the time they occurred) for engine RPM, jackshaft RPM, overdrive and temperatures, total run time, the Overdrive 1:1 point where engine and jackshaft RPM cross, and the staging RPM.

After-Test Graphs plot RPM and jackshaft speed, exhaust gas and cylinder head temperature, plus the CVT, overdrive channels and calculated wheel speed; data can be reviewed in RaceStudio 3 Analysis, AiM's free software, with time plots, setup sheets, histograms and scatter plots.

Karting version available on kartshop.me.
