KC4B - Quality Patched 1693S Firmware
The Official Thread
Michael Buffer on the microphone “In the blue corner is LiteOn and in the red corner is the Code Guys. The Code Guys were the winner of the first 2S series - can they do it again with the 3S series. Let’s get ready to rumble…”
Hehe - I know it’s been a long time coming but finally here it is - well at least for the 1673S/93S and +/-R media at 6x, 8x, 12x and 16x. I have to say I’m pretty pleased with the results so far.
What is it
The aim of this firmware is to produce lower PIFs. It uses a WOPC (Walking Optimum Power Control) technique that adjusts the OPC at fixed points during the burn.
It’s already crossflash patched for 1673S users, has a faster LED flash rate when burning and has the following read speed changes:
+R/-R = 16x
ROM/9 = 12x
+/-R9 = 8x
Notes
- This firmware is experimental and is not supported or condoned by the drive manufacturer. You will void your drive’s warranty if you use this firmware.
- Remember this patch affects +/-R media at 6x, 8x, 12x and 16x only.
- Some PIF spikes may occur at the recalibrate points, but like the NEC drives, these seldom cause a problem.
- Stay tuned to this thread for updates.

I’d say the reboot wasn’t required. You’ll be pleased to know that every burn I’ve done so far has had less PIEs and PIFs compared to KS0B or KS0A.
