Alan SMR2u Posted January 21, 2019 Report Share Posted January 21, 2019 Hi guys. Can anyone point me the way to setup COP on 4age + Atom G4? Thank you Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 22, 2019 Report Share Posted January 22, 2019 From a setup point of view about all you need to do is set the ignition mode to direct spark and enter suitable dwell times for your coils. Quote Link to comment Share on other sites More sharing options...
Alan SMR2u Posted January 22, 2019 Author Report Share Posted January 22, 2019 Thanks for the info. Any idea on the wiring diagram? Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 22, 2019 Report Share Posted January 22, 2019 That will depend on what coils and ignitors etc. But it is pretty simple. The coil on #1 cyl trigger wire goes to ecu output ign 1. Cyl 2 goes to ign 2 etc. Alan SMR2u 1 Quote Link to comment Share on other sites More sharing options...
Alan SMR2u Posted January 22, 2019 Author Report Share Posted January 22, 2019 So its quite straight forward. Im using the k20 coils Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 22, 2019 Report Share Posted January 22, 2019 So those coils have built-in ignitors. I havent used these coils before but the pic below found online. Pin 1 is the trigger wire as explained above. Pin 2 is ground which should ideally be connected to a clean point on the cylinder head (not manifold etc). Pin 3 is +12V, this should come from a relay that switches on and off with the ignition switch. Alan SMR2u 1 Quote Link to comment Share on other sites More sharing options...

Alan SMR2u Posted January 22, 2019 Author Report Share Posted January 22, 2019 Is there any diagram i can download? I kinda lost it. Thank u Quote Link to comment Share on other sites More sharing options...
cj Posted January 23, 2019 Report Share Posted January 23, 2019 For the coils themselves? here's the first good result from google, which lines up exactly with what Adam said. Sounds like you want the sequential option Alan SMR2u 1 Quote Link to comment Share on other sites More sharing options...
Alan SMR2u Posted January 23, 2019 Author Report Share Posted January 23, 2019 Thank You CJ! Will try it out hopefully all goes well 23 hours ago, Adamw said: From a setup point of view about all you need to do is set the ignition mode to direct spark and enter suitable dwell times for your coils.

cj Posted January 23, 2019 Report Share Posted January 23, 2019 Heres what I ran on a recent K20a build. These times were half way between those transcribed from a hondata K20 base map (bit higher by maybe 0.5), which are usually pretty close to stock honda, and a chart that motec published on the denso part number(bit lower by 0.2 ish I think). TBH either set of numbers seemed to run well. make sure to set spark edge to falling as well for these coils. Quote Link to comment Share on other sites More sharing options...
