If you advanced the timing, or the new system is giving you more complete
combustion, then you should either see an increase in economy, or an
increase in power. I would guess that the fire is staying in the cylinders
longer, leading to higher oil temps. Watch for detonation.
To support this theory you should have seen a decrease in EGT, increase in
CHT and oil.
I would also pull the plugs and inspect them for signs of detonation, or
preignition, or overheating. Check the timing to make sure it is not too
advanced. Make sure the plugs are not too "hot". I'm talking about the
reach of the plugs and their ability to sink heat into the cylinder head.

Subject: REFLECTOR:Ignition Question
I recently installed a Klaus Savier electronic ignition on my Velocity
(Lycoming LIO-360-C1E6). Previously (with the mags), my oil temperature
always ran around 190 degrees. Now, with the electronic ignition, it
constantly runs at 220 degrees. Cylinder head temps run around 340 degrees.
Is this normal? Any solutions to bring the temps back down in the 190s?
I'm worried about where it will run during the summer months. It is at 220
when ambient temps are in the high 50s.
Thanks for any advice or input,
Jack
