Cop with CDI 97+

[mastermatt87]

Research for 7 hours and can’t find anyone that has posted the correct way to wire a COP with CDI to 97+ CAS.
I’m reading there are 4 ways to wire it.
CDI and non CDI wiring.
95/96 CAS and 97+ CAS.
I’m running a 95 ECMLink v3
99 engine top to bottom with a 300m COP and an Dynatek ARC-2 system.

I’ve found many forums but they are not specific to 97+ COP with a CDI system.
If anyone knows or has photos how to I would really appreciate it thank you.

The reason I’m asking I believe I’m wired for non CDI and my engine has a lot of hesitation at 4k + on test pulls

add more chassis grounds, intake to firewall, trans to frame rail, bell housing to firewall ( use starter bolt ground )

if issue persists then go from there. i just know body grounds play a huge part in ignition on dsms, especially mine

I'm confused as to why the CAS makes any difference here? The ECU tells the PTU or the CDI when to charge and when to fire. The CAS tells the ECU about where/what the current engine timing is but it's the ECU that runs the ignition.

Hold the phone...
If the engine runs, and you have spark on 4 cyl, and you can idle - then it is wired correctly.

Issues over 4K + would be something else IMO

I appreciate that. I was concerned with wiring because I see 4 ways to wire it.
CDI non CDI and 95/96 cas and 97+ cas I wanted to check make sure I’m 100% right to rule out a cop issue

You can wire it incorrectly and still have it idle with spark on all 4. The whole parallel wiring of the 300M coils that people are doing can create a new layer of problems with misfires that could seem worse under load. Always wire the 300M coils in series. It looks like you wired it correctly.

Where did you set the rev limit on the ARC-2? Is the hesitation about half of that? The cam/crank switch on the ARC-2 really is about telling the ARC-2 how your system is set up, whether it fires 1 or 2 times per crank revolution so it can calculate RPM. If you get that setting wrong, you can make the box think you are are 2x the rpm, and it may hit the limiter early.

Another thing that can cause the timing to get thrown off is the rising edge vs. falling edge setting. This changes depending whether or not you kept the PTU in the system when you wired it.

We have 3 cars running 300m coils and arc 2 box's. We always kept the PTU so wiring or settings without it i do not know. With it i am thinking we all are restrike, rising edge, crank? i would have to look at my car to confirm. Like brads said PTU or not effects when it fires the coil. Dsm i recall goes from 0-12v so rising vs say evo 8 that goes from 12-0 falling edge to look for when to fire.
