Which ECU for nistune for R33?

[pauly24]

Im looking at getting nistune up and running on my R33.
Im still trying to decide on if I should get a R32 or Z32 ECU.

Theres still problems with both ecus that im not sure on how to fix, with the R32 ecu you can get a controller for the VCT. But there is an idle switch problem, how is this fixed?

Also with the Z32 ecu, you can solder a wire together to get the use of both knock sensors. And it already has a VCT control. But ive heard there is also a problem with the idle switch.

Can someone exaplin this idle switch issue better to me.

Also with the Z32 ecu, do I need to get a TT manual one, or will any one do? Just the auto NA ones are much cheaper.

Thanks.
