Hi guys, first post here. I've got a 94 Accord coupe Obd1, and have a H22A Type S engine in it. So the engine has ATTS, after reading on the forums for a while I've learned that ATTS will not function at all when it isn't used with its proper ECU. So having ATTS in my car but not working, does that have any effect on how the LSD works? Will it cause any damage to anything? Also is there any way to get it to work using my Obd1 ECU? Thanks.

 

Without the ATTS computer controller and all sensors working... it will act just like a stock open differential. Since the ATTS controller gets some data/information from the ECU, I am unaware of a way to make the ATTS system work correctly with a USDM OBD-1 P13 ECU.
