I went to the NHRA opening today and talked to some of the people from Hurst about installing a line loc on the Z and the potential issues with ABS.
Basically they said the install is the same as without abs but there's a potential that the drive by wire power reduction would still turn on depending on where in the system the computer checks and so rendering this solution as useless.

I soooo wish I could find a 350Z owner that has ABS still enabled and a line loc system installed, there has got to be someone around...
