need help with FAST XFI and LT1 problem..128 code

have my FAST XFI harness and all for my BBC..but
until it gets here I threw my old LT1 in the car to work out any bugs
on the suspension and things..

anyway I bought the LT1 ign adapter harness and the car fired right up..
I got my idle and light accel tuning done..
but now as soon as I get to "EXACTLY 2850 RPMS" it sets
a 128 code-"crank sync error"..

all that I've read is that it's a plug and playdeal..
everything is selected correctly in the "operational parameters..
I went back over all connections and grounds ...and all is right..

my concern is what I see on the ign adapter harness and print... where it is only using 3 wires from the opti..
with the cam sync wire grounded at the "CAM?HALL EFFECT" connector end..

what's up with this..?!
I thought maybe it would only work in Bank to Bank..but it's the same thing..
this is maddening!

Thanks Ahead for any info!
Matt
