Hello their, I have a 1995 Civic Ex Sedan with USDM B18C1, CTR cams, Hondata S300J on Jdm P72 ECU... When the engine is at normal operating temp Idleis at 850rpm and I switch on the A/C the Idle drop excessive.. What I'd like to know is the Difference in Electrical configuration... USDM ECU's use an ELD, JDM ECU's do not.. I'malready using the D10 for my Wideband Sensor.. What can I do to eliminate this using a JDM ECU with a USDM B18C1..

Ok, Gunmetal so I took my laptop to work and started increasing the IACV slider one increment at a time. All it's doing it's increasing my idle. Idle still drops to about 530 then it kicks up to 730.

Looking at the ETM the US ECU's have an ELD input at D10 which like I said earlier is used for my WideBand Sensor, and other is an Output at A16 which is Alternator Output Signal... Should I also "Disable" the Alternator Output Signal in my Hondata???

Or Remove pin A16 from Connector??
