Does the PFC use the signal from the BAC valve to regulate idle or can it be deleted with no Ill effects? Car in question is any FC that has a PFC installed

 

The PFC does not require the BAC (or ISC on the FD), you have to adjust the throttle manually to compensate

 

Thanks for the quick reply. On another side note lol how do you mount the commander in a FC? I know there is a bracket for fd's but I haven't heard or seen anything like that for the FC?

 

I have had a PFC in my FD since 1999 and never used a bracket.

 

That's cool, do you know of any mounting backets for a FC?

 

banzai sells a mounting bracket for the FC as well

 

While the BAC isn't required, it does certainly help with cold start idle up and in general use situations. There is no performance penalty for keeping the BAC installed either. So, my advice is to use it.

 

FC & FD Commander holders http://banzai-racing.com/store/PFC_c...er_holder.html

 

No disrespect to Banzai...they have a great product and it is a good way to mount your PFC. Personally myself (and others) bought a cell phone holder ($15 from Wal-mart) that I attached to my vents and puts the Commander in the perfect location for me.

Once again Banzai has a great product also and you should consider it.

 

I personally do not like the idea of the drastically increased chance of breaking the louvers out of a vent assembly with a cell phone holder. The FC vents are expensive and the FD are not even available new any longer. Having it block any of the heater controls is not something I want either. This would be why we came up with this:

 

vents are for air bro, the HVAC system already sucks in Rx-7's and there's no need to make it worse

I have an oldschool Gotham Racing holder in my FC, which was never actually designed for a 2nd gen

 

I'm sorry but if you are breaking vents you are doing it wrong! =)

 

I guess you don't understand, we are not breaking any vents as the commander is not hanging from them, which means we are not doing anything wrong.

 

I've found that you can't use the bac valve on an jdm s5 as it makes the idle bounce
