Hi All,
For my personal Turbo conversion project I have also ran into the issue with the 56x series ECU's and their slow failing due to the hybrid module rosin cracking, resulting in a approximate 15 year shelf life, and many many headaches.
After many internet searches and some investigatory reverse engineering I came across this site, for repairs on the Porche LH computers: https://home.kpn.nl/mirjam_paul/928_lh_repair.html
So I gave him a call, turns out the hybrid module can be replaced by a more foolproof reversed engineerd version without the issue of open to air silicon chips. I asked him if the chips were universal, to which I got the suprising answer that Bosch decided to change them for each revision (Still supspicious of this, will try to confirm soon, with comparison of 563 and 984 ECU hybrid modules).
Since I am currently studying to become an electrical engineer, and also up for a challenge, I created this thread to work together on a solution for our LH2.4 and LH2.2 cars, which would probably come in the form of a cheap affordable diy kit.
