theFiztec Posted May 20, 2019 Report Share Posted May 20, 2019 Hi there, Im using Link G4+ Plugin Evo 1-3. It has already tuned and engine has been running well for the past 2 weeks. However, this morning my battery died and i changed to new battery. After starting, engine run abnormal and after checking there is no output from Ignition 4. I run the test using the Ignition function. Please assist on what is the issue and if i can temporarily use Ign 5 to for Ign 4. Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted May 21, 2019 Report Share Posted May 21, 2019 If ignition test is failing to fire the coil, check the continuity from the ECU to the coil. Check the power and ground at the coil. Ideally use a test LED to confirm if you have a pulsed signal in test mode to the coil. Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 21, 2019 Report Share Posted May 21, 2019 Hang on, the Evo 3 is wasted spark - it should only use Ign 1 & 2 by default. You cant use Ign 4 on the Evo 3 plug-in as it has extra hardware connected to it to control the main relay circuit. Quote Link to comment Share on other sites More sharing options...
theFiztec Posted May 21, 2019 Author Report Share Posted May 21, 2019 I’m using the plugin evo 3 on my Daihatsu K3-vet. Everything sort out already. Found that my coil is dead. Changed it and engine is back to normal. But @Adamw, are u saying i can’t use IGN 3 and IGN 4 to sequential for Ignition due to hardware configuration? jk2030 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 21, 2019 Report Share Posted May 21, 2019 Ign 3 is ok, but Ign 4 is interconnected with another circuit that could make it behave erratically. DI3 is also linked to the relay control circuit on Ign 4. So for instance if you put 12V into DI3 or turn on its pull-up resistor you will find ign 4 wont work. jk2030 1 Quote Link to comment Share on other sites More sharing options...

Already removed it and things is normal now. But will consider to run wasted spark. Thanks adam. Is it possible for you to email me the schematic diagram for plug in Evo1-3 so that i can know how the hardware is connected and take into account in my wiring.

pugsparked Posted October 26, 2020 Report Share Posted October 26, 2020 On 21/5/2019 at 8:54, Adamw said: Ign 3 está bien, pero Ign 4 está interconectado con otro circuito que podría hacer que se comporte de manera errática. DI3 también está vinculado al circuito de control de relé en Ign 4. Por ejemplo, si coloca 12V en DI3 o enciende su resistencia pull-up, encontrará que el encendido 4 no funcionará. Hello, with the G4X Plugin EvoI-III it continues the same. Di3 and IGN4 are not friends is something that should be fixed Quote Link to comment Share on other sites More sharing options...
Simon Posted October 26, 2020 Report Share Posted October 26, 2020 It will need a bottom board revision to resolve this. The bottom board has been unchanged between G4, G4+ and G4x. It is ear marked to be revised in the future. pugsparked 1 Quote Link to comment Share on other sites More sharing options...
