Re: Perth - Someone who knows sync and reference with WOLF 3d?	Wed, 05 October 2005 17:07

The Theories of Teh Witzl from what i know, the CAS will have TWO x 2 pulse/RPM sensors and a 24 pulse/RPM sensor (G1 and G2, and the 24pulse Ne)... each having a common earth (G-). The two G sensors are 360 degrees out of phase, and the one you will want to use is the G2 sensor, since it triggers on TDC compression for cylinder 1. *ref: http://www.autoshop101.com/forms/h23.pdf p.9 onwards* In the standard setup from Toyota, the ignitor has internal logic circuits which determine which coil to fire based on the ECu's output signals IGt, IGdA, and IGdB. The TOyota ECU works out these signals using the reference signals of G1 and G2.... Now - in the case of an aftermarket ignition system, such as the Wolf 3D v.4 in question.... # G1 is not used. # G2 becomes the "SYNC" trigger (TRIG2), being a 1 pulse per camshaft revolution signal, generating its signal as the engine approached TDC compression on cylinder 1 # Ne becomes the "REF" trigger (TRIG1), being a 24 pulse per camshaft revolution signal. # There is NO NEED to cut any teeth, unless there is something i am fundamentally missing here.... Some Tips: # ENSURE that you DO NOT connect the shielding from the Wolf's ignition trigger wires to any earth or other point at the engine. The factory toyota loom has the shielding connected to earth... this is not cool in the case of aftermarket ECU's, as they generate their own internal signal earth and shielding in a special manner to ensure signal clarity. # be sure to have a MINIMAL length of unsheilded wires where you make your connection. In fact if possible maintain the shielding by folding it back, connect your wires and then RE-WRAP them with the sheilding when making your connections at the CAS. Unshielded wires induce signal degredation # In some cases, the common signal earth to the unused G2 sensor can cause signal noise. It is recommended to cut the earth wire from the G2 sensor to eliminate this possibility (but be SURE you have it correct - it should be white inside the CAS) Now.... if you have connected the CAS as per the diagram Alan provided above, what is possible is that you have used the G1 sensor and not the G2 sensor. -> Check the wiring from your Wolf to your CAS and that it is correct, fully shielded, and that the shielding is not connected to anything at the CAS end of the loom. -> Make sure the CAS is aligned correctly and that everything is good I have also noticed you are triggering by a RISING EDGE... can you confirm if this is to compensate for the Toyota reluctor sensors' ouput going positive first, and then falling below zero and then coming back to zero. I ask this because the installation book for the Wolf3dV4 keeps saying the reluctor must go negative first.... *** much information gathered from Autoshop101 documents, wolf3d books, my experience wiring up an Autronic SM4 to a 7M-GTE, and a few other bits of info here and there I've taken the below from the linked PDF above, so that all can see clearly what I am refering to and you can work it out for yourself. Read the PDF above to understand fully. *note: these specifically refer to a 7M-gte igntion system, but should be applicable to the 1G-GZE system [Report message to a moderator]
