All the tutorials use bfl stock 1.2.5. Is there really any speed gain?

I want to use this http://ck.kolivas.org/apps/cgminer/BitForce_SC/

We used the pre-compiled firmware from ckolivas that he posted here.

Being a JTAG interface I would suggest dumping your original firmware first prior to flashing for an original image.

In that case I would suggest that would be quite difficult to achieve!

Wasn't there an image linked earlier that would return to stock? (from the BFL site)

Looks to be just front panel cables to a case, nothing special.  You just need something that will carry a signal.  Doesnt have to be a JTAG cable specifically.  We used a IDE cable that just hung off the side.  Worked just fine.

The .hex provided by BFL is version 1.2.5, I don't think we'll be seeing an official release of v1.0.

Watch out, that one came with a standard jtag cable.

I also bought this

http://item.mobileweb.ebay.com/viewitem?itemId=330887001508

One was used in the picture, one was cut and soldered to clips. Now I have 3, standard, clips and individual.

Thanks for the link, did you try this with a 5Gh/s unit, or the upgraded 7Gh/s. If you have the upgrade, how big was the jump? I have 4 upgraded Jalapenos each running from 7.2-8.2Gh/s, just wondering if its worth the risk for the extra ~10% performance.

No don't risk a seven. I went from 5 to 7. Basically did a free upgrade.

Just flash 3 Jalapenos with ckolivas' image.  2 of them are over 9ghs!

My third one is not doing so well.  my hardware error rate is 2x my accepted!

Any ideas?

Use the original one released by BFL, the cklovias image greatly relaxes the power on diagnostics for the chips and will disable the ones that aren't working correctly
