i have a d15z1 block with a d16z6 head. i put a adjustable cam gear on it to compensate for the half tooth off issue. but i dont know if im supposed to time the cam as a z1 or a z6 since they have different marks. ive been searching every writeup and posting i can find but nothing says anything with a z1 block. as of right now its running timed as a z6 with the cam gear being off 4.75 degrees after being set at 0 to catch the belt. i tired the best i could to set base timing but the motor idles to bad to get a good reading. i bleed to whole coolant system over and over and i even swaped iacv's. i even ordered a new custom base map for my setup and that hasnt helped the surging idle and the too rich condition at idle, also there is no power loss and it runs great at higher rpms, just at idle under 1k it wont run right. please if anyone knows the exact specs the z1/z6 minime is supposed to be set at let me know!!!!
