looking for any threads on who made their own COP with CDI set ups.. any help would be appreciated

 

any help would be appreciated everytime i search on this site i get nothing even close to what i put in to search for..

 

Check the ECUFlash forum. Someone there has made one. Can't ever find the link again myself.

 

DSM Ignitor and GM Coils ? Is that what your looking for I have the link if so.

Edit: Went and found the link here it is. DSM Ignitor and GM Coils on Stock ECU

I tried it at one point and it worked for one pull and then stopped working for me. Since then I have given up but I think Im going to give it another go seeing my stock COP just **** the bed.

 

Not technically a COP, but there is no reason this should not work if you are on an extreme budget. Any DSMer in the area should have an ignitor you can buy. You could even substitute the stock DSM coils instead of actually buying new ones. Not a beautiful solution though.

If you are seriously interested in making your own CDI, you will need 4 Chrysler 1999-2004 300m coils 3.5L (~$25-$40 e/a), coil connectors/pins $25 (4x Toyota P/N 90980-11246 (connector), 1x Toyota P/N 82998-12440 (pack of 10 wires)), the M&W, AEM, or Dynatec box, automotive grade wire for the coils (14-16 ga), a mounting plate, 2 male Mitsu ignition connectors (these are impossible to find so you'd likely have to cut/splice or butcher the stock coils), heat shrink tubing, and some split loom tubing to cover the mess.

In addition, soldering and metalworking skills would not hurt.

Cut the aluminum plate to size (15"x2.8" for 8 or 9) and drill mounting holes. Do this by taking a piece of wooden dowel that fits inside your chosen mounting hole. Cut it about 1/2" long or so and insert in screw hole. Quickly color the top end of the dowel inside the valve cover with a magic marker and set the plate down in the valve cover. This should transfer the exact location of the mounting holes onto the plate (you are using the dowel rod as a stamp). Next, cut out/drill holes for the coils and mount them.

From this point on carefully read the manual and wire the coils one at a time then hook the unit up. This should start a good basis for a DIY kit.

 

I made mine with some 300m coils, AEM Twin Fire, custom plate for the coils and HKS DLI connectors. It is plug and play!

I can have the COP swapped for the OEM setup in matter of mins.

BTW, I posted the details in the AEM forum. Same username as here.

GL for those venturing on making their own COP.

 

what are the gains....is it worth it?

 

i was actually thinking of the same thing... why do you guys use 300m coils?

 

I have pieced together a kit with the Dynatech box that works great also.
