richardc9052 Posted June 22, 2014 Share Posted June 22, 2014 Right i got an ecu from a 1992 Jap starlet soleil to fit to my car. From what i can tell, ignition setup is the same design and everything else should be the same. Did these come with an immobiliser? The car will start for a split second and then cuts out and wont start again unless i reset the ecu.. Any help appreciated. Green label is jap ecu Quote Link to post Share on other sites
mikey4410 Posted June 22, 2014 Share Posted June 22, 2014 I don't think there was any type of immobiliser that early on dude, and if I am wrong and there is an immobiliser it wouldnt be bypassed by simply disconnecting of the battery. Quote Link to post Share on other sites
richardc9052 Posted June 22, 2014 Author Share Posted June 22, 2014 well i reset the ecu by disconnecting the ecu.. but it only starts for litterally less than a second each time and then wont again until i reset it so its not bypassing it, more like only realising it needs to kick in again. I didnt think they had an immobiliser that early either but its got me thinking now..I opened both my ecus and, well the jap one has a lot more going on inside. I checked the pinouts and they SEEM to be the same.. Quote Link to post Share on other sites
mikey4410 Posted June 22, 2014 Share Posted June 22, 2014 Hmm, yeah not likey to be an immobilser, only thing I can think is maybe a transponder in the key, if nit that then maybe an old alarm? Quote Link to post Share on other sites
richardc9052 Posted June 22, 2014 Author Share Posted June 22, 2014 i have fitted it to my starlet so what ever is causing it is on the ecu side.. a transponder in the key would make sense alright but thats an immobiliser isnt it? Quote Link to post Share on other sites

5e colin Posted June 23, 2014 Share Posted June 23, 2014 beeing jap will have a diferent pinout i thinks richard ??? or different dizzy ?? Quote Link to post Share on other sites
richardc9052 Posted June 23, 2014 Author Share Posted June 23, 2014 no its all the same i think Quote Link to post Share on other sites
daniel_g Posted June 23, 2014 Share Posted June 23, 2014 The only thing i can think of is this. Im not entirely sure what it is tbh. Duno if its relevant or not.It sits just infront of the ABS ECU in my 85, it was plugged in when i got the car but since i changed the looms for GT looms there was no plug for it.

richardc9052 Posted June 23, 2014 Author Share Posted June 23, 2014 Hmm have you tried your 85 in a non jap 4efe ep8? Quote Link to post Share on other sites
daniel_g Posted June 23, 2014 Share Posted June 23, 2014 No i havent unfortunately. See your key is it just a metal blade ? Quote Link to post Share on other sites
richardc9052 Posted June 23, 2014 Author Share Posted June 23, 2014 the one in my ep80 is yes but my 4efe loom doesnt connect to the car it literally runs the engine and thats it. no diagnostics. just the bare essentials Quote Link to post Share on other sites
fiddlersport Posted June 25, 2014 Share Posted June 25, 2014 the key reminder (white box) is just for when you leave your key in and it will bleep ? pop off the lids on both ecu and match the pinouts, the uk spec ecu might have the imo pin which is the immobilisar pin so that could be your issue or the jap spec ecu might have had a external coil or ignitor but its very easy ti identify if you simply pop off both lids and compare the pin-outs, hope this helps but i am a newby when it comes to wiring lol Quote Link to post Share on other sites
richardc9052 Posted June 25, 2014 Author Share Posted June 25, 2014 I have done and they seem to match Quote Link to post Share on other sites
jack_wetone Posted February 4, 2015 Share Posted February 4, 2015 Did u sort this prob ? Quote Link to post Share on other sites
Steven1995 Posted February 5, 2015 Share Posted February 5, 2015 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.

Steven1995 Posted February 5, 2015 Share Posted February 5, 2015 Here is what's on the pcb's of my (Belgian) ecu and the japanese one Quote Link to post Share on other sites
daniel_g Posted February 5, 2015 Share Posted February 5, 2015 I still need to finish off my N/a GT build and see if it all works. Using the JDM 100ps Gen1 ECU from my 85, and the engine ancillary loom plugged into the GT fusebox. Quote Link to post Share on other sites
jack_wetone Posted February 8, 2015 Share Posted February 8, 2015 Here is what's on the pcb's of my (Belgian) ecu and the japanese one hi thanks for the info very handy did u get it to run? i have the inlet manifold an tb from the same car so i have the right sensors to go with it, could u give me a bit more info on what wires u joined together just im not quite sure witch ones u joined ?thanks Quote Link to post Share on other sites
Steven1995 Posted February 9, 2015 Share Posted February 9, 2015 Sorry I made a mistake in it, it's the IGT that's different between the 2, if you change the wire from location it should allready start. Like I said i haven't tried to make the tps work yet, and I probably won't anymore as I've got an emanage blue now. Quote Link to post Share on other sites
KPJUK Posted June 15, 2015 Share Posted June 15, 2015 I have been experiencing the same issue with a 1999 Corolla ECU. I performed and engine swap from a 2E engine to a 1999 4E-FE in my EE90 Liftback and I can't get the engine to continue running. It starts for less than a second and cuts. The ECU clearly needs an immobiliser signal. I wired in the Immobiliser box and taped the key to the transponder but it still isn't having any of it. Has this problem been solved yet?
