I'm still looking for any wiring diagrams , service/diagnostic and parts info on these EFI systems .
Some OSO a hole sold me spares a two years ago . He screwed me out of the manifolds though , threw everything in a ****ty box that broke in shipping losing some of it's contents and never provided me with the service books he claimed he had .
I'm putting these motors in my old Chris and anything would be of great help in getting these things up and running .

Those computers do not work that great part throttle. I believe the only way you can change any of the tune up is by changing some of the resitors inside. I may have one distributor for that set up. You would be better off installing new electronics inside that big computer. Fast xfi would fit.
I do agree new electronics would be a step forward .

My drives are presently at Offshore In FLL getting rebuilt , but if I can find a couple of spares for decent price I'll bite .
I've been offered junk for stupid money so far , however there is a gentleman in upstate NY with a pair that may be worthwile .
It seems anyone with a spray can suddenly has a fresh pair lol .

Yesterday I spoke with Errol Lanier whom I had met in the late 80's . He is well and building an awesome line of small cats . He could not help , however he referred me to Mel Riggs @ Riggs Marine in Wisconsin as had OSO member Biggus ( Thank You ) So I did call him and he is checking .
I have motors assembled and almost dyno ready .
Here are a few more pics .
Anyone with anything ?
( shop manuals , wiring diagrams , diagnostic info )

Thanks , I think they helped us out way back when the Chris Cat was almost new and Jason sent me a couple of racing tapes .
