Did you update the latest firmware to version 1b?

Yes that was the first thing I did.

 

[3.3Turbo4me]

I'm not sure but it does not make a different on the stuttering.

So that closer gap and map 6 didn?t work?

 

[Hungtran505]

Did not gap the plug yet. I have new plug and coil on order per kia. Then ill gap it.

 

[freefloyd]

Appreciate you early testers taking one for the team.

My misfire came after driving on the second day. Drove it on the highway and did a few WOT and it started to hesitate, didn't get any check engine light but I could tell the car wasn't driving right at WOT. I haven't had a chance to regap the spark plugs yet and may end up ordering different plugs before I resintall it.

 

[Hungtran505]

I was talking to kia a few days ago and they are investigating it they are thinking the coil is the main problem to the misfire issue when in high rpm.

If the misfires are caused by tunes, how do they associate the coil problem with an un-tuned motor? Did you tell them the engine was tuned?

 

[Hungtran505]

Too much psi. I took my tune off for warranty work. I'm just waiting for the coils to come in then I'm going to tighten the gap on spark plugs. They had cars that is doing thr same problem without the tune on it.

Are you saying Kia thinks the stock Stingers are producing too much boost pressure?

 

[Hungtran505]

No. They are thinking the coil is bad something is wrong with the boots that goes over the spark plugs. They are pushing around 12psi.

I see.

 

[Hungtran505]

I see.

Not sure if they are going to be a recall on them or not. They are treating it case by case at the moment.

In my case it only happened after installing the tune.

Take your tune off and put it back to stock and take it to your dealership and tell them its jerking and misfiring in boost. If they ask you about a chip or tune just say no.

I took it off already and it runs fine now. Should I still take it to the dealer?

 

[Hungtran505]

Yes I would. Did you try running it in sport mode?

 

[sciprox]

With the tune on I did not. I haven't tried Sport mode since taking off the tune.

Try driving it in sport mode. on my it happen when I'm in boost does not matter what mode I'm in.

 

[MrMr]

Anyone in Canada had a chance to try this yet? I had originally plan on ordering this until I started reading some of the issues.
