Hi there lads. I bought a wired in a HKS EVC IV recently but it was second hand so there was no manual I'm not sure what to do. I find a manual that said u have to hold the ALT and MODE button together to engage "Learning Mode". This isn't working out for me. Any help plz?
just dont bother with the learning mode, just reset the unit put in psi and put the max psi to run overall, then just set up the gain and it will be good to go... play around with setting a and b if you want different high/low boost options.
