Tom_s_e3 Posted October 31, 2019 Report Share Posted October 31, 2019 Hi there I am finalizing my engine harness design for my evo 3 .. I have a link g4+ pnp . I am making quite a few changes to the original loom hence why I am making a complete new loom.. I will be using later evo triggers instead of the cas and using a kigly 12 tooth crank trigger wheel and using oil and fuel pressure transducers and fitting a wide band knock sensor .. also will not require hold power as I will be deleting the iscv and using idle ignition.. now to the point lol I would also like to use either r35 gtr or audi r8 coils in sequential ignition rather than wasted spark.. I have searched the forum and have seen a post saying this is not possible due to the ignition drive being used for hold power and that you can only use ign drives 1-4 to run sequential ign ..and not on the expansion loom ... is there a way round this? Does the board have to be modified? Is this possible to do myself ( I have experience with soldering and desoldering ecu boards repairing and removing chips ect from std evo ecus ) if so how would I go about this .. thanks .

Brad Burnett Posted October 31, 2019 Report Share Posted October 31, 2019 if you arent using the hold power, the drive can be configured as ignition. merely a wiring pinout change. Quote Link to comment Share on other sites More sharing options...

Are you definitely sure on this, specifically on the Evo 1-3 Plug-in? Because, I too have seen the posts @Tom_s_e3 is referring to, that states this isn't possible due to the ECU Hold Power circuitry on the bottom board. I'd like a definitive answer too, as I would like to also utilise sequential ignition on my Evo 1-3 Plug-in. Tom_s_e3 1 Quote Link to comment Share on other sites More sharing options...

I'm fully aware on how to wire the ignition outputs and configure them .. my point is I have searched the forum an seen posts saying this is not possible due to the hold power circuit on the evo 1-3 pnp board. If this is the case I would like a definite answer as this will clearly affect how I build my engine loom if I can only run wasted spark.

Brad Burnett Posted October 31, 2019 Report Share Posted October 31, 2019 @Adamw @Simon would either of you guys be able to offer a definitive answer on this subject? Quote Link to comment Share on other sites More sharing options...
Simon Posted November 1, 2019 Report Share Posted November 1, 2019 On the EVO 1-3 board there is additional circuitry on ignition drive 4 so with out modification it can not be used for ignition function. We can happily modify this for you if you wish. Quote Link to comment Share on other sites More sharing options...
