But yesterday I rang up MV Automatics to find out info on the stage 1.5 shift kit for the A342E gearbox in my JZA70 front cut. Micheal said the A340E that's in my GZ20 Soarer now is better than the A342E as the the A342E runs out of legs when you get up to 300kw and the A340E keeps going. This is when I asked him if the 1JZGTE computer could run the different auto box and he asked about the ecu for the auto box. So I said the guys on Toymods said the JZA70 doesn't have an ECU for the auto box and he said he was sure they did so he said contact Danny at Japanese Motorsports. He said it should be in the passenger side kick panel. Danny wasn't at JMS so I spoke to Chris and at first he said they don't have an ecu for the auto but he put me on hold and came back to tell me he was wrong and they do have an ecu for the auto and it should be right next to the engine ecu and there should be 2 small plugs that go into it. He even said he could supply me with one. I have come across an ecu with 2 small plugs, one white and one blue. The white one has 'natural' written inside of it, I thought it might be Japlish for Neutral, ie neutral switch on the auto. There is a plug that fits the blue plug and the wires going into it are all blue. This ecu was sitting in a pool of water by itself on the drivers side when I picked the front cut up so the id tag on it has peeled off. My friend Russell (Poombah) has a JZA70 and he reckons his has an auto ecu in the passenger side kick panel. I've seen some tech wiring diagrams that show some wires from the auto box going to the main ecu and some going to an ect ecu which I assume means electonic controlled transmission ecu. It also says the little pig tail coming off the main ecu goes to the ect computer. Anyway, I think the easiest thing to do is cut back the spiral insulation around the main loom and trace the wires from the auto box to the main plugs. - Chris. [Report message to a moderator]
