hey i just got my car all fixed/sorted and its running great now. only problem is that since ive gotten it back from the workshop, i cant seem to turn my turbo timer on again? I called the workshop and they said that they did not touch any wires or anything related to the turbo timer, but i cant seem to turn it on?

i think its a HKS type 0 turbo timer, its got the four buttons: M, S, T1, T2.

Anyone with any suggestions?
