The SPL, or Second Program Loader, is essentially the Android bootloader. It's job is more than just loading the Android OS - it also offers several other boot options, including Recovery mode, Fastboot, and HBOOT modes, and ultimately it's the SPL that allows manipulation of the flash nand on your device. Part of the SPL's job is to ensure that the data flashed to the device is correct. Most of the current shipping SPLs (apart from the "Perfect SPL's) let us flash a complete ROM image, but don't let us flash a recovery rom or boot image as it checks the verification signature. Haykuro has modified the SPL's available to remove this check and this is what the Engineering SPL's available offer. As the SPL is so crucial to the handset though, you have to be very careful when flashing it as if it's updated incorrectly then you may be incapable of restoring it without specialised hardware and knowledge. You essentially have a very expensive brick ;)

Haykuro quote : "T-Mobile myTouch : 1.33.0006 and 1.33.0010 is the dreaded "perfected" SPL".
This means that it's currently not possible to run "fastboot boot image" on these SPL's, so don't try to flash them.
