I see I can enable knock sensors, two different cooling fans, A/C, which I don't currently have. I have read you can exchange one of these and control lock up. I was considering the X Max but may go manual trans which would make the extra cost a waste. Does it need a VSS to control lock up? Not planning on using one at this point. Planning on ordering the Terminator and the drop in Holley fuel pump in the next month or so.
