RM11 CAN be replaced with 3 resistors:
From pin 1 to 2...10k ohm (digikey# 10kebk-nd (200 for US$4.70))
2 to 3...51K (51kebk-nd)
3 to 8...12K (12kebk-nd)
No MIL and normal operation
unplug Vtec sol and MIL functions correctly by throwing CEL.
I'm not smart, just observant and persistent: look closely at a P72 if you want to see where I came up with this.
Editors note: This RM11 replacement will probably NOT work for auto ECUs if the feedback on the auto trans lockup solenoid is required. A true RM11 or additional resistors would be required to run both a vtec and auto trans solenoid with feedback.
I removed an RM11 and measured all the resistances. This should allow someone to come up with an electrically identical replacement.
