I've tried this too, and there is at least 1 pin different. The pin labeled as IGF on the board is on a different position, the one next to it, on the jdm ecu. I soldered the 2 together and than it ran for more than a second. I had some other problems regarding the TPS and ICV too. I don't know if the uk starlets have a on/off type tps or a variable, but if you have a variable you'll need a on/off type as the ecu doesn't recognize a variable one.
