Obviously it is not controlling VDI and AP, they need to be wired open/sleeves removed. Technically if I felt like it I could sit down and configure a couple of the sequential twins solenoids to operate these correctly, but that requires a whole new product. There are less then 10 people running the PFC on S5 N/A's so it really does not warrant the R&D.
The turbo control actuator output from the PFC, FD pin 4R, will switch a ground at the "Sequential turbo transition high" rpm setting in the settings 1 tab of the Datalogit. Sequential turbo control would need to be switched on--this is fine as there are no ill effects from doing so. So the only thing necessary is inserting a pin with unterminated wire into pin 4R, or instead of an unterminated wire you could match it up to the correct pin on the s5 n/a harness so that a rat's nest electrical connector could be used.
The pin 4R output could be used to control either the aux ports or VDI by adapting the stock s5 system. Since the aux ports can be a bit of a pain I'd rather remove the sleeves but switch the VDI with the PFC so you get the variable intake runner lengths. You could make the aux ports work but you would have to have an external RPM switch to do so and of course make sure the sleeves are moving freely.
Easier said then done. Trust me when I say I have looked at this. First the smog pump and ACV need to be kept intact to supply positive pressure, this is a deal breaker right there for most. Then I personally would not offer a half working system, so I would have to configure the CRV and boost solenoids and offer vacuum routing information. I would not offer any information at all until I personally tested it, theoretical system function is not worth anything in the real world with out proof positive testing. This takes time on a dyno that I do not feel we will ever see the return on. We do not market this product to the N/A owners for this very reason, however we do offer a level of support for those that choose to install it since we have had success making decent power on stock ported engines.
