well i just got off the phone with my tuner and my car is going in on friday to get the emanage ultimate fitted. All this talk of power has made me antsy. I dont think the ultimate needs the ignition signal adapter like the older version does, but i iwll soon find out. As for the zener diodes i think that i will put them in anyways, just waitning for and email from 666DAN. NO one else has a wiring diagram for the inclusion of zenners in the ingintion wiring do they?
