Thanks to all that replied.
I think at this point I can go two directions.
1. Buy a 60-2 tooth cranktrigger and a 332 for managing it (would be a piece
of cake with a 332, right ?)
2. make my own enclosed optical trigger and go the route like listed on the
site.

Here are a few more questions..
1. what would the price be for a 60-2 cranktrigger and the 332 stuff
compared to DIY trigger and the cheaper processor.
2. Is a 332 capable of an easy way to convert my system to SFI. I was
figuring this way: read injector pulsewidth from ECM and determine the
injection timing and  fire the accordingly. If it wouldn't be too hard to do
then I think it's best to go for the 60-2 trigger for easy upgrading later.
3. Has anybody on this list used his ddi for enginebraking ? I have a friend
who has done this and he said it was working great, but he had 4WD.

Any price indications ?

Thanks in advance.
