quick question
 

i just obtained a hks pfc fcon. it was in a trade of parts. im going to be getting a haltech e11 eventually. i know the hks unit helps when you have the stock ecu but is it very useful with the e11 or just dead weight?

sry if i sound dumb classicauto but im searching for information if i knew the answer i wouldn't post.

The PFC F-CON requries the stock ECU to work.
The PFC F-CON is a piggy back computer that requires the stock ECU to be installed and working.
You cannot use it with a Haltech ECU.

What car, might just be worth your while to just get an E8 plug in if its an S4 or S5?
