Hks Evc5 Issues

[chalkey]

Hi all, I've got a problem with my evc 5, my son was in my car and has pressed the centre volume button and reset the peak hold, now it won't boost. I've read the instruction manual but it doesn't say how to set it again. Both A and B settings for boost are the same as before but P.H is is highlighted and there's 0.0 next to it

Any ideas how I sort it out I need it for work in the morning

Thanks in advance chalkey

PH just shows what the maximum boost you've hit for that setting, just take your car for a spin and your PH will displayed again
