Dan No Posted October 2, 2014 Report Share Posted October 2, 2014 I have a couple of old G1 v4 ECUs. Wondering what sub-board is needed to work with the distributor triggering on Toyota 4A-FE or 7A-FE engines? These are newer than 4A-GE and have no crank-trigger. Everything runs off the distributor. Thanks. Quote Link to comment Share on other sites More sharing options...
Simon Posted October 3, 2014 Report Share Posted October 3, 2014 They will probably have a 24 and 1 configuration in the distributor. You would require a sub-board for the 24 and 1 (same as 3sge). This however is the most popular sub-board and we have run out. Quote Link to comment Share on other sites More sharing options...
Dan No Posted October 17, 2014 Author Report Share Posted October 17, 2014 Reviewing the G1 v4 manual, I found this section:6.3.2 Trigger & Hardware Requirements Cylinder PulseFor the correct timing of ignition, the crank or cam sensor MUST provide a signal that can be decoded to produce one pulse per engine TDC. On a4-cylinder engine for example, this is 2 TDC pulses per crankshaftrevolution (4 per Camshaft revolution) and an 8-cylinder engine will have4 TDC per crankshaft revolution (8 per camshaft revolution)Sync PulseTo determine the correct firing sequence, a sync pulse is required as areference to determine engine position. The sync pulse can only appearonce on the crankshaft (1 signal per engine revolution) or once on the camshaft (1 signal per engine cycle). Here is the G and NE trigger signals from the cam-driven distributor.NE satisfies Cylinder Pulse 4 per Camshaft revolution requirement andG satisfies Sync Pulse once on the camshaft (1 signal per engine cycle) requirement.Which sub-board would be needed for this configuration? Would you be able to release technical-details on the sub-board functions or schematics? I would be able to build a sub-board if I'm not successful in finding one from one of your dealers.Thank you.

Dan No Posted October 17, 2014 Author Report Share Posted October 17, 2014 I also have a circuit ready that will convert G & NE into 5v square-wave signal if that's something the G1 can accept. Thanks. Â Quote Link to comment Share on other sites More sharing options...
Simon Posted October 20, 2014 Report Share Posted October 20, 2014 If its a simple 4 and one then a stock reluctor board can be used. Which we do have. Quote Link to comment Share on other sites More sharing options...
Dan No Posted December 7, 2014 Author Report Share Posted December 7, 2014 Ah, that's perfect. How much are these reluctor sub-boards? Part#? And may I stop by and pick up two of these? Thank you. Quote Link to comment Share on other sites More sharing options...
Dan No Posted December 7, 2014 Author Report Share Posted December 7, 2014 Also do you have 60-2 sub-boards? I'd like to get two of these as well. Thanks. Quote Link to comment Share on other sites More sharing options...
Simon Posted December 8, 2014 Report Share Posted December 8, 2014 The 60-2 is the same board as used for the 24 and 1 toyotas so sorry no go on that one. Cost on the boards is $150+gst No problem to pick up, this cost would also cover a full unit test of you wanted. Quote Link to comment Share on other sites More sharing options...
