I remember Dr Drift saying something that this is one of the limitation of the e-Management with Skyline. That's it doesn't work with the ignition harness or something.
Would be intresting to find out, cause I was thinking of installing the e-Management as well with my auto. No chance with the Power FC and the HKS F-cons with auto. Motec might be too expensive, my mechanics also mention Links Computers but don't know how good they are. Also Unichip but don't know if they will work with auto either.
Damn auto!! hehe
