Quality Patched 1693S Firmware for 1673S, 1693S, 720A, 800A (KC4B)

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. :wink:

More information
Please read the documentation enclosed in the package, for more details.

So it’s ready to go for 1673S, 1693S, 720A and 800A users – enjoy. :slight_smile:

MCC004 @ 16x




YUDEN000T02 @ 8x




RICOHJPNR02 @ 8x (almost as good as the T02)




MCC003 @ 8x (this is the release WOPC pattern)




:bow:
I knew that Lite-on was going to be my next Writer :bow:

Thanx for your great work…

Let’s go to pick-up a new 1693…

It would be nice if we had the chance to see scans of the same disc burnt before and after the quality patched firmware

Wooo! C0deking really the king!!:slight_smile:

@code,

Great Work dude.

Time to Test.

I’ll Try That :slight_smile:

I Have Very Limited DVD+R’s Here At The Moment.

So This Is What I’ll Do:

Flash To KC1B Do A Reset Learn.
Burn 5 Verbatim MCC003 DVD’s In A Row, Reboot After Each Burn.

Flash To KS0B Do A Reset Learn.
Burn 5 Verbatim MCC003 DVD’s In A Row, Reboot After Each Burn.

Then Post My Quality Scan Results Here.

If Time Permits I’ll Repeat The Process With SONY 8x DVD+R (SONY D11).

If Anyone Thinks This Is A Dumb Idea Or I’m Going About It The Wrong Way.
Just Let Me Know. :smiley:

Ricoh RICOHJPNR03 @ 12x

This media is amazing at 12x with KC1B :), but don’t even think about 16x.

@pulsee
Going to put me to the test aye - your keen. :wink: 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.




Hmm … can it do RICOHJPNR01 at 12x like my BenQ? Then I’ll consider :stuck_out_tongue:

KC1B VS KS0B In A 10 Round Fight

5 Rounds Of Verbatim MCC 003
5 Rounds Of Sony D11

I Will Post The Results Of The First 5 Rounds Tonight (MCC 003)
All Burns Are From My Real 1693S And Scanned From My 1673S@1693S.

Round One

(Sorry C0deking But My 1693S Is Not Likeing KC1B So Far)



Round Two



Round Three

KC1B Is Getting Worse With Every Burn :frowning:



Round Four

Here’s A Better One From KC1B But No Where As Good As KS0B On My Drive.

(Please Note All Tests Are From The Same Spindle)



lui_gough, show me a 16x +R burn from the Benq that comes even close to a total PIF value like this: :stuck_out_tongue:

Pulsee what do you mean by writing “Do A Reset Learn”?

download the eeprom utility. you can reset learnt media with it. read the included docs.
