Stock plugs on Ess m3?

[zyh66619941008@gmail.com]

What brand are you guys tuning on Ess m3? Ess told me to use stock but I seem to have power issues, like the rpm struggles on 6 to 7 K rpm. I have stock spark plugs( newly installed when I got the supercharger) could the issue be my spark plugs or my old coil packs.

The stock plugs are fine. With normal driving I would replace them every 6 months.
If you put new plugs in and still has issues look at coils

Check your old post. I told you on post #3 what fixed mine. Can't keep on asking the same questions if you didn't make a change.

I m sorry man, because some guy from a tuning shop is telling me that I can't use stock, it confuses me.

Do you have dct or manual? If you have dct do you have lag issues if you use auto mode?

Using non-OEM plugs will only add more variables. Stick with stock plugs.

I just put it on 4K miles ago, so I guess I would just do the coils first then, will the bad coils lean to damage on the new spark plugs?

Shouldn't, but weak coils will typically fail under load/high RPM. A dyno would be able to point this out right away.

I have a manual.

So lets get this straight.....

It only lags in Auto mode?

I would think you would be safe keeping the same plugs in there and run new coils.

Do yourself a favor and do it and report back how the car runs after that.

Yes, if I use manual, I feel the power right away, if it auto down shifts, it will have lag about 1 sec, the rpm still revs up and the car still accs just feel like no full power

Ask the "guy from a tuning shop" if he is willing to recalibrate all the needed parameters for the ionic misfire and knock sensing to work as designed if the plug is changed. Just the diameter of the electrode and gap alone can effect the sensing, much less the materials it is constructed of.

Finally! I got my car right! It's the coil, plugs are fine!
Really want to thank you being patient and nice! Thx!

So the lag is normal on dct, according to AJ from Ess, power won't apply until clutch are fully engaged

Dyno looks good, healthy numbers.

Nice! Thanks for reporting back. Did you replace all 8 injectors?

I used the injectors that came with the supercharge. Should I get new ones?

Thx! Coils really saved my day. Haha

I'm sorry. I meant did you replace all 8 coil packs?
