Explode64 Posted December 7, 2016 Report Share Posted December 7, 2016 The link Kurofune looks to use 3 of the 4 AMP/TE connectors that are used on the factory FD RX7 loom.I know that the pin positions are different but is there any reason the Factory wire harness cannon be re pinned to plug into the Kurofune?I assume all it needs is the pins/wires to match the ECU outputs? (or swap a wire or two from big to small crimps)This seems like a straight forward task as I just replaced the plugs 3 weeks ago after a pervious owner destroyed the clips.

Scott Posted December 8, 2016 Report Share Posted December 8, 2016 Hi,Have you considered using our RX7 S6 plug-in ECU?The Kurofune does have 3 sockets that match the 3 largest plugs of the RX7 S6 ECU wiring loom.Scott. Quote Link to comment Share on other sites More sharing options...
Explode64 Posted December 8, 2016 Author Report Share Posted December 8, 2016 (edited) Thank you Scott For the memory the S6 plug in is very limited with very few inputs/outputs..Will there be any issues with the outputs either being high or low that don’t match the OEM wire loom. i.e triggering Relays to ground or +12?Also it is compatible with the factory sensors and trigger? Would it run the OMP? Edited December 13, 2016 by Explode64 Quote Link to comment Share on other sites More sharing options...
Scott Posted December 8, 2016 Report Share Posted December 8, 2016 The only special hardware we have on the RX7 S6 plug-in ECU is for the A/C request. This comes in on pin 79 and comes in on Digital Input 3. The signal from the A/C controller only drops down to 1.5-2.5v (depending on blower fan speed), this is not enough to always trigger the digital input channel.Both the Kurofune and RX7 S6 plug-in ECU work with the standard sensors and triggers. Something will likely need to be done for the A/C request signal if you use the Kurofune.Both ECUs will run the Oil Metering Pump.Scott Quote Link to comment Share on other sites More sharing options...
Explode64 Posted December 9, 2016 Author Report Share Posted December 9, 2016 Scott What voltage will trigger a digital input? 12V? James Quote Link to comment Share on other sites More sharing options...
Scott Posted December 9, 2016 Report Share Posted December 9, 2016 Hi James,For a digital input channel the on/off threshold is at ~1.5v.Scott Quote Link to comment Share on other sites More sharing options...
Explode64 Posted December 13, 2016 Author Report Share Posted December 13, 2016 ScottHow do people overcome this Aircon trigger voltage issue with a wire in ECU?Is a differential amplifier or voltage amplifier required to boost the AC signal?Or can it be run off a unused analogue input Quote Link to comment Share on other sites More sharing options...
Simon Posted December 13, 2016 Report Share Posted December 13, 2016 A quick fix is to put a couple of diodes inline which drops the voltage enough. Quote Link to comment Share on other sites More sharing options...
