Pwer Fc And Alsd

[FineLine]

My build is near complete and the car will be going to the tuner in a couple of days. Info on the power fc running the alsd is difficult to obtain. Have any of the more experienced users had any dealings in this area and, If so, what is required to marry the 2 together?

"Vehicles such as the Nissan Skyline R33 GTST that feature the Active-LSD or A-LSD and SLIP function (lights on the dash and vspec diff) will suffer A-LSD compatibility problems. The car will operate correctly and the diff should as well however you will experience "A-LSD" error/failure intermittently. To date there is no known solution for this problem. It appears to be only present on the R33 RB25DET. There was a limited run of R33 known as the GTS25TML spec which is the M Spec with Active LSD. The diff is a skyline GTR vspec diff, electronically controlled LSD instead of a normal R33 diff. It features the same finned cover and A-LSD function as the Skyline GTR. The A-LSD and SLIP functions in the Skyline GTR with the Skyline BNR33 PowerFC work fine, only the ECR33 with ECR33 PowerFC is affected."

I seem to remember a discussion on here from a few years ago about this, and from what I remember the problem had something to do with the throttle switch signal not being passed from the power fc to the lsd controller. Could be wrong as it was a while ago. Try a search for alsd.
