Ben Hainsworth Posted April 1, 2014 Report Share Posted April 1, 2014 I've bought an AE101 Levin (20v 4age silvertop) it has a link ecu, it was running on this ecu. Previous owner ran it out of oil and replaced the motor. Couldn't get it to run, now I have it. Checking the basics the base timing appears to be out. It's firing well outside when it should (10deg after tdc). Timings all set up right, dizzy can only fit in one position. I was told it may be possible to offset the triggers by altering switches inside the ECU but can only see jumpers. Can you advise if this is possible?

Simon Posted April 1, 2014 Report Share Posted April 1, 2014 On that ECU there is no offset adjustment. It is geared to work off a 4 tooth trigger only. I suspect that the pickup in the distributor might be a 24 tooth wheel? Quote Link to comment Share on other sites More sharing options...
Ben Hainsworth Posted April 2, 2014 Author Report Share Posted April 2, 2014 Previous owner had old engine still, lo and behold the dizzy only had 4 teeth... Quote Link to comment Share on other sites More sharing options...
Simon Posted April 3, 2014 Report Share Posted April 3, 2014 I would be putting that one in the hole and you will be good to go again. Quote Link to comment Share on other sites More sharing options...
Ben Hainsworth Posted April 3, 2014 Author Report Share Posted April 3, 2014 It had been sitting outside for a while and was a bit shitty looking so I modified my one. worked sweet testing it by hand but now it's cooking the mitsi igniter that's been fitted (J722T). I read the manual and it mentioned certain igniter types need to be hooked up to Trig2 instead of Trig1. I've got a stock Toyota one now as well, (same as in your 1uzfe diagram) can you confirm what trig to use? Quote Link to comment Share on other sites More sharing options...
Simon Posted April 3, 2014 Report Share Posted April 3, 2014 Both I would have expected to work with the ignition 1 output. (blue wire with no trace) Quote Link to comment Share on other sites More sharing options...
Ben Hainsworth Posted April 4, 2014 Author Report Share Posted April 4, 2014 I refitted the Mitsi one and operated the dizzy by hand with the plugs out. Have spark again out of coil but had poor spark on cyl's 2 & 3. Checked cap and rotor, both fubar, especially contacts inside cap. If gap excessive in the dizzy and the spark was being held up, would that load up the igniter and cause it to get hot? Quote Link to comment Share on other sites More sharing options...
Simon Posted April 7, 2014 Report Share Posted April 7, 2014 It could cause a bunch of energy to head back to the igniter and in really bad cases even the ECU. So in short yes it could cause this to get hot but in theory only while cranking. Quote Link to comment Share on other sites More sharing options...
Ben Hainsworth Posted April 15, 2014 Author Report Share Posted April 15, 2014 New cap and rotor it fired straight up. Coil was relieving itself back into the igniter. Thanks for your help with this Simon, as usual very impressed with Links support and knowledge. Quote Link to comment Share on other sites More sharing options...
