Sorry if the question is a noob-ish, im coming from the Nissan VQ world but i need to know the options for piggyback management on the SC400, I have searched and most of the information is not that clear cut/nobody has experience or post results with experience. The options i am consider are:

Unichips(price makes it very attractive)
SMT-8
Emanage Ulitimate

The only thing that i know for certain will work is the emanage but its universal. btw this will be for a 95 SC400 w/ a Z trans, so no vvt to worry about.

Thanks in advance.
