The SPADE system is the first hardware to ship pre-loaded with tunes of this caliber. No emailing, laptops, or learning curves needed. The SPADE may also be used to run diagnostics and log data for analysis. Logged data may be emailed to for changes and troubleshooting, review or analysis. Updated tuning files can be emailed, making the SPADE field upgradeable.

The Ace comes with five tunes you select.  We highly recommend calling and speaking to a member of our helpful team to decide which tunes best fit your modifications and usage.
