Coil-On-Plug(Non CDI, PNP type)

[pangyau]

Hi all,

Any of you tried Coil-On-Plug(Non CDI, PNP type)?
Reason of looking due to miss-fire.
1. While on WOT (Wide Open Throttle) at RPM4-5K.
2. Normal cruising then sudden accelerate to overtake.

Done:-
1. Change the plug & check the gap (NGK BPR8EIX)
2. Check the hoses & change my IC piping (upper/lower).
Before & After IC ping change….Still the same.
3. Change the plug cable to NGK & Stock.
4. Clean the Throttle Body (TB).

The ride is stock condition.

Last bet is the Ignition Coil problem.
No option to test/borrow from other E owner.
Probably need to buy then test again.
For COP, which is suitable (brand, price & available in here?)

Someone selling new one - BASIC Unit (CDI). Price Sgd 1250.

Okada direct ignition Plasma coils (range from S$500 - S$900 depend on used or new).

TM Workz Ignition Coil - approx. S$600 - 700 used

Base on my reading (on Net).
The CDI unit require aftermarket ECU to control/utilise it.
The the unit have different set E1-E8 than for E9.
According to Spark Tech website it seem not compatible on E8MR.

With all this aftermarket Coil (the price very subjective).
What are the positive/negative impact on the stock ride?
Any comment very much appreciated.

CDI can be used with all cars irregardless if using stock or aftermarket ecu. So long as the CDI box can take the signal from your igniter or ecu. What is not compatible is the coils. CDI will not work with certain coils with a build in ignitor. In d CT9A case, you will need to replace the coils to "dumb" COP type coils or get a compatible OEM coil from d pajero family to work. Mitsubishi is using wasted spark so a CDI box will work with it if it can take the signal. It is when you want to go to sequential and this is where you will need an ECU that can do this and to control timing and dwell time.

You OEM coil is just fine. I would only go COP if planning for CDI and sequential and with pencil coils. Just using COP alone may not offer much benefits. Again this depends on the coils. The pencil/AEM/sparktech type coils are better than you typical COP like the ones on car now. Just get the OEM one if your car is stock. Don't bother with the china made ones. Get original or OEM Types.

Evo's are well known to have ignition coil problem due to the heat of the engine bay. Oh, also check your CPS - cam position sensor. Did you relocate the battery and how is the grounding.

mine Evo8mr using this one, direct ordered from the website.

for Okada Plasmas, it does not work with standalone ECU. that's what i heard.
just in case if u change to standalone in future.

 

[pangyau]

AlucarD,
The battery still at original position.
The grounding, I had extra by using Sun Auto Ingnition Blade.
Cam Position Sensor (CPS) possibility the culprit?
What reason the sensor to be faulty/damage?
I'll check it later...

CDI systems probably suitable to modded+high power engine.
Also swapping to Pajero parts & try and error cannot be done at this time.
That's the reason for Non-CDI type as my preference.

Take note on your recommendation on Pencil/AEM/Sparktech

H22-C,
Any review could you share about the unit?
Just PNP & remove the existing coil?... How about the wiring/socket?
Saw a few E owners at my place, their Okada burn due to few reasons.
As the unit is expensive, so I need to be careful on choosing.

Standalone for stock ride...? some said is wasted modded to me...
As the ECU are expensive...

 

[AlucarD]

Friend, a faulty cps will cause misfire as well. But it will be very apparent across all rpm range. Your case is most probably coil related. No harm checking. The sparktech system is a very good unit albeit overpriced. I prefer HKS DLI if u retain the stock coil or if you go CDI. M&W or Dynatech's. But you will need new coils. A budget system will be some MSD tower coils. You can rewire them to work. They can be had for RM600-700. But you will also need some plug wires and depending on some people. The engine bay may look cluttered.

err, i am running on Okadas and also on Standalone ECU ...

thx for the clarification. btw, what ECU r u using ?

Update,

Tested with other stock coil/plugs/cable plugs from a friend.
Still having problem during WOT or at RPM 7k.
Exhaust produce popping sound around & small black smoke for around 2-3 seconds.
Sounds like miss firing...

Please advice me what other thing to do.

bro,

You said i/cooler piping already checked and changed. Did you do boost leak check?
I also having the problem like the car jerking when you crusing suddenly you want to accelerate.
After doing the boost leak check, i ended up changing 2 i/cooler hoses and several clamps.
Now it improves alot with boost 1.3 bar. With 1.5 bar suddenly accelerate, still got this kind of jerking but not much.
