Converting an MSS54/HP into an MSS54HP CSL (H-bridge)

[SliM3]

For installing the H-bridge chips I first clean all the old solder from the pad, then apply clean solder to both the pad and heat sink of the h-bridge. Heat board and chip with a heat gun, apply flux to hold the chip in place on the pad and re-flow the solder with a blade tip. Don't touch the chip, just the corner of the pad and the solder will re-flow perfect every time.

Whoever you get to do the conversion, if it doesn’t
come back looking like this, it isn’t done well.

Reflow ovens are the best but you can achieve similar results with correctly applied heat.

What is everyone's feeling on letting Kassel do the conversion?

So all of this work is just for the flap functionality?

The H-bridge is what is required for the flap. Everything has to do with running CSL software on an HP (or converted non-hp).

Did you also saved the modified 0pa and 0da files for winkfp flashing?

Unfortunately, I couldn't save those. The modified binaries can be found here though: http://www.msstuning.com/mssflasher.html

i saved them. just unzip and both WINKFP files are there.

Where can one get Paffy's modified MSS54HP CSL software for non-h-bridged DMEs? Gonna need it if/when my turner CSL box ever ships...

just use martyns binary modification tool to disable Flap DTCs and you are done. There isnt a separate Bin file for h bridge and no h bridge

^Its there in the github link that you quoted. It is also on his website.... Flash the full for the modified "OS+Tune" then choose the partial needed if changing IE to manual. You can use the 0401 XDFs to modifiy...

Should it be mentioned that one can flash Paffy's modified MSS54HP CSL software onto a MSS54HP without hardware modification. Only thing lost is the H-Bridge right?

Technically it’ll work fine with the H-bridge too, though if you’re going through that much work you may as well BDM the thing.

Thank you so much for such a detailed writeup! Some photos in post 4 are missing, or it is my browser?

Looks like it's not just you. Thanks for letting me know! Fixed.

Do you guys use water soluble flux paste for easy clean up?

I don’t now what its solubility is, but I like ChipQuick’s gel flux. Cleans up okay with alcohol.

I usually do the same thing even with a chisel tip. Works great to the point where I don't even bother with the hot air except for removing stuff.

Finer pins can be tougher, but I did manage to replace one of the main CPUs using basically the same technique.
