N. California is having very unusually warm temps .... mid 80's .... The 87 190e 2.3 has started pinging. I notice it most during the warmest part of the day, so obviously there is some relationship.

I replaced the "infamous" power resister to see if this helps.

Is it normal for an engine to ping more when it is hotter out?
