Snap-on Solus Ultra 21.4 Update |link|

The Snap-on Solus Ultra remains a legendary workhorse in the automotive diagnostic world. Even as newer wireless units take over the market, the Solus Ultra’s reliability and lightning-fast boot times keep it in the hands of professional technicians. The 21.4 software update is a critical milestone for this tool, representing one of the final major leaps in its diagnostic capabilities.

• Autel MaxiSYS Ultra (MS909): Autel typically releases updates monthly. However, Snap-on’s 21.4 includes more domestic truck coverage (Ford Super Duty, Ram HD) than Autel’s Q4 release. Snap-on also has better OEM-style bidirectional controls for GM.
• Launch X431: Launch is faster with Chinese and European coverage but lags behind Snap-on in guided diagnostics. Snap-on’s SureTrack database in 21.4 still has no equal for real-world fix rates.
• OTC Encore: OTC is simpler and cheaper, but the 21.4 update adds features (like the heat map graphing) that OTC cannot match.
