I hope this can become an conclusive thread for those wishing to upgrade to MS3/MS3X.
I shall be using the following directions, but have a question and possibly a correction for them.
1: If I do the mods below, pop in the ms3 card, fiddle with the software some, it should work in my stock batch-firing configuration with the stock CAS, right?
2: And then if I wire the NB crank and cam sensors to the CAS plug and change the timing settings? I read that the NB CKP and CMP outputs are electrically identical to the CAS outputs, besides the number of teeth.
When I say work, I mean fuel and spark. Obviously my IAC isn't going to work if I don't have provisions for it on the mainboard(Thats what the expander card will be there for
3: In the second picture, I need to remove the jumper from tachselect to optoin? (Its not jumpered in the picture, but it is on my board) I'm thinking this was an implicit step.
4: Do I also need to connect S12C and JS9 to get 12V to the daughtercard? According to the MS3 build step 23 (http://msextra.com/doc/ms3/build_manual.html
), I do.
More questions later.
