How To
Modify your SBEC for MPFlash
In order to install the MPFlash module, you need to remove the factory chip, clear and/drill the 4 additional pads needed for the 32 pin module socket. These include the additional pins for E (Enable), Prg, RW, and A15.
If you have modified a SBEC for a BoostButton flash module, then this part is not really any different. If you have socketed a SBEC, or have a socketed SBEC already, you are part-way there! You will need to add a socket for the 4 additional pins however.
!Caution!: Be sure to practice appropriate personal protection when working on the ECU boards, and soldering. The electronics potting compound used is nasty stuff and very harmful when off-gassing or being vaporized during heating/soldering. You are responsible for your own protection, so doing any of the work below is AT YOUR OWN RISK.

Top Side work area
Work area on the top side of the ECU is identified in the image. You will need to carefully clear away the potting from this area to gain access to the chip.
Top side work areas cleared
You can see the cleared top work area.
In the area of the chip, you need to clear out extra area to the right of the chip. You can see the additional potting cleared from that area. This is where there are 4 additional pads that need to be cleared and/drilled.
Factory Chip Removed
Remove the factory chip, extract any pins or excess solder. Clean area with 90% IPA and acid brush and/or cotton swabs.
Also, you need to clear and/or drill out the 4 additional pads on the right (2 top row, 2 bottom row) in line with the chip pins. On or two can be cleared with a solder extractor on most SBEC's. The other 2 or so are not through holes and need to be drilled.
Install the 32 pin Chip Socket
Install the 32 pin chip socket onto the ECU, there is plenty of clearance in the SBEC housing, so no reason really to not use the socket technique. This will help if there is ever a need to replace the MPFlash module as you won't need to do any further heating on the ECU board. But, you may choose to mount the MPFlash module directly on the ECU, like in most SMEC applications.
Install MPFlash Module
Land the MPFlash module (SinglePlay or MultiPlay) onto the 32 pin chip socket.
Additional potting compound was removed to check circuit traces. The 4 extra pins sometimes need extra care and attention.
