Dyna FS Curvemaker Programming kit. USB. The 2000i module is adjustable with switches, like the earlier 2000i, but now also programmable through a PC to suit your ignition demands (curves) for maximum performance. Another new feature is data recording. The module records a series of data and stores it. The recorded data can be downloaded with a PC to show engine builders how the engine was used (or abused), should there be a problem in the future. Note: 902524 programming harness Pigtail is also required when using 902528 programming kit. It must be purchased separately.
