Would a Spider DCCD controller put me back operational, with full control of the DCCD operation ? I sent a message to Spider, no reply.
I'm going to try to hide my jealousy for your JDM STI for a minute and tell you what I know.
Not sure why your DCCD doesn't work, probably missing some sensors or something somewhere. I know in the states there are some weird pitch sensors on some of the later years but I'm not sure exactly which ones. I think someone once told me that if you're missing those sensors your auto DCCD won't work because it won't see signal from certain spots.
Anyways, to answer your question, I would think the Spiider would work. The Spiider system is totally independent of anything in your ECU besides a couple of signals off of the ECU. It connects to the two wires on your tranny and basically just puts signal through your center diff to lock/unlock it. That said, I'm not 100% sure that your voltages are the same on the JDM STI. If I was you I'd try to find as much information out about the signals the spiider uses and see if they're the same. For example, make sure the voltage for the DCCD is the same, make sure the TPS signal is the same, etc. I would imagine that they would be because a lot of people here in the states swap with JDM harnesses and ECUs but again, can't be sure because I've never tried. Good luck to you.
