Can anyone help me with the HKS EVC-IV
Can anyone help me with the HKS EVC-IV
I didn't get any instructions with my EVC-IV boost controller. I would like to know what the four wire plug is for and how to use its functions? Please help.
If you call HKS and ask for their tech department, they are more than happy to help you with their products. If you have a fax machine, they fax the manuals to you. They did this for me with my EVC and F-CON.
