Swazy 0 1 Cars Posted December 31, 2005 I want to run the orig. ecu on the loom from the xu9jaz, does it match? I hope so, don´t want to mount the loom from mi cause i already mount the loom from the jaz! You know the base was an 205 xs with tu-engine Share this post Link to post Share on other sites
petert 601 Posted December 31, 2005 I want to run the orig. ecu on the loom from the xu9jaz, does it match? Yes, if you have a 3 row Mi16 ECU as well. All you need to add is the two wires for the idle motor, and a wire for the knock sensor if you're using one. Share this post Link to post Share on other sites

An knock sensor i don´t use. Sorry my english is not the best, so whats an idle motor?? Wish u all a good start without probs in the year 2006 Greetz from germany Share this post Link to post Share on other sites

All you need to add is the two wires for the idle motor, and a wire for the knock sensor if you're using one. we have you saying this and some other saying it's a pain in the ass to use it as the length of the wires doesn't match up at all and there are some other issues with it... An knock sensor i don´t use. Sorry my english is not the best, so whats an idle motor?? it's an ICV (Idle Control Valve) that is mounted on the inlet manifold and adds air to the engine when the throttle is closed. gti uses SAD (Supplementary Air Device) that works in a different manner (there's an articles about it on the website).

Swazy 0 1 Cars Posted January 3, 2006 Banjo tired adding the relavant wires and failed in his mission, Peter can you post some wiring diagrams? I am happy to host if you need some webspace. So it´s better to use the orig. Loom from the mi16?! I´ve got one here, it was quite easy to mount it, so i didn´t wanted to mount the one of the mi16. But i didn´t mount the engine yet, so it shouldn´t be a big problem to mount the loom. The only question is, the loom from the xu9jaz is connected with the loom for the lights and stuff over the orig. connection, could i connect the loom of the mi over this orig. connection too? This connection is underneath the dashboard, will means by european cars with left stearing under the right side of the dashboard Share this post Link to post Share on other sites
IvarS 0 Posted January 10, 2006 (edited) This is an easy mod, in my opinion. You need to add the knock sensor, or Motronic will switch over to "limp home mode" and the engine fault light will come on. The only tricky part is adding the extra wires into the ECU connector. Idle valve The same 12V-feed as the injectors, other cable to pin 4 in connector (ground through ECU). Knock sensor Same 12V-feed as TPS and coolant temp sensor (pin 46, I think!), other cable to pin 30 (empty). What I did was tear off all the tape from a Mi16 loom, find the cables for idle valve and knock sensor, then copy the wiring into the XU9JAZ loom. Guess what, it works Edited January 10, 2006 by IvarS Share this post Link to post Share on other sites
Banjo 1 Posted January 10, 2006 Cool, will have to try again with my loom. Ben Share this post Link to post Share on other sites
