As above I have recently done a head build on my B18C1. Toda cams spec A, skimmed head, Mugen 2 layer HG, Skunk2 IM, ported ITR TB and Teg R ECU to run it, and its pulling really well too until I get it tuned.
Problem is its idling high when hot. 1000rpms, and if the headlights and interior fan are on it can go up to 1600rpm.
Now because of the high idle...how can I assure my ignition timing is set correctly as Honda ignition marks are based on a 750rpm idle. Would the extra few revs advance the ignition enough to make it incorrect if I set the timing based on a 1000rpm idle.
I have fully adjusted the IACV too so its at its minimum as far as idle adjusting goes.
Any help appreciated
