No just speaking in general.

Not everyone shows everything they do to a car.

 

There are even tuners or people that borrow a Demonstrator or hire car and then apply a remap.

I personally know people that have a car for a day or 2 and might just see what they are like with a bit of an upgrade.

Not internet myth.

Not all cars are equal and manufacturers ex Media cars / reviewers  test cars/ long term test cars can have more go from time to time.... 

 

Before and after Dynos have their uses.

They are just an indication obviously but imagine spending £399 to have a car perform worse on the road in the real world.

Tried engine running and disconnected coil packs one at a time. All of them had a visible effect to the running of the engine. Included an example of the spark plugs 

Not bad looking if all 4 are the same.

Looks like wear on the tip, so check the gap and see what all 4 are.

New spark plugs might well be an idea since you went to the expense of remapping it.

I included this picture as it seems to be the worst one of the four. I'll just pop round Halfords and change them anyway and hope for the best. What should the gap be?

Sorry no idea for your car on the Gap.

Have you no Local Motor Factor for spark plugs at a reasonable price?

 

As to the spark plugs the reputable remapper / tuner should have a recommendation on spark plugs and gap they use.

Have you spoken with them on that before going to buy anything, and get any fault codes read.

Genuine or even OEM specific fitment should be pregapped 0.6 or 0.7mm depending on who you listen to.

 

The one picture posted looks quite oily on the thread and some carbon build up around the eletrode.  Although a bit hard to say as it doesn't show detail that well and no benchmark against the others. Gut feel is I'm not sure about 12k miles so probably change.

 

These were my originals at 38k miles 5.5years.

 

Edit: The bosch aftermarket code is 0 242 245 576 and they specify 0.7mm. There are others that can be used as well.

 

PS Were the mappers not willing to help?

Might not be the case but I've heard that after a remap car might act a bit weird until it gets used to the new conditions. Probably most of the car owners won't feel any difference (I didn't feel anything wrong after my remap, except the additional power) but yours might be the one. Who knows...

Could there be a bedding in period after a remap?? I've ordered some sparkplugs and just took it for a run on the motorway to see where the problem exactly kicks in and it was definitely only occasional this time around. Last night was consistent .

Look at my post above. My remap guy said that there might some weird things for like the first 200km or so. As I said previously, nothing bad occured but if he said so then there might be some cases.

It's an interesting theory I suppose.  I've had a few maps on different cars but haven't been told that before.  All the maps I've had before worked straight away and if there was an issue, it was a result of old/failing components giving up due to the extra stress.   Two of the maps I had on Skodas caused coil packs to fail but the maps themselves weren't the issue.

There is a lot to be said for having that remap done where the vehicle can then go on the dyno.

 

James the tech that knows about all there is to know about VW Group engines has posted before about dirty diesel vehicles needing time after 'The Fix'.

As for Remaps and petrol models you usually drive in familiar with your vehicle because thats what you drive and leave happy as Larry and giving it some when every chance appears.

Big downer if you spend good money and all that you get is a car feeling sick that supposedly needs miles on it until it behaves properly.

I've ordered the STS version of Shark S1, but I'm tempted to see if I can pop into Shark in the future.  I'm sure if I pay them the dyno fee, they would fine tune the map for me.  Just not sure when I'll next be down that way...

In fairness you wont get a deal more bhp having it tailored. The stage 1 map is good out of the box anyway.

update. spark plugs were changed and all coil packs seem fine. Two days later and the oil light flashed followed by the EPC light coming on. I got home and first thing was to check the oil, the dipstick came out dry!! I've obviously topped up the oil and the EPC light has disappeared. I've since complained to the All electric I bought it from and they are maintaining they performed the service even though 3 months later I have no oil in the car. The engine still stutters, mostly under harder acceleration when the turbo kicks in.The engine management light flashes also. The guy that remapped it said most likely gas recirculation valve (I assume he means EGR) and is very unresponsive. I've asked the question at the little garage I used to use any they suggested as a VW engine they would check the MAP sensor first and the N70 valve.... (never heard of that)

forgotten detail

What engine trouble codes is it producing?  Coil packs don't always show problems at idle, if that is how you checked.

 

Edits:

Also, it is possible, the car is using oil, which will be a problem if it is being burnt. The only plug photo had some deposits and appeared a little oily, but didn't look bad bad. It wasn't the best photo for examination though.

 

I suggest you monitor oil level over set mileage, like 600 miles or more to make sure you don't have problem.

Edited 7 June, 20178 yr by TheClient

waiting to get the car in to be read. Issue doesn't happen during casual driving only when I get the turbo to kick in and push the car a little. I only tried disconnecting them individually and checking response with engine running. Was that naïve of me?

No, but it will only show a fault that way, if the coil pack is faulty at idle. Sometimes they may function ok at idle and show faults under load or higher RPM for example, where the voltage requirements are higher etc.

I am sorry to say that, but I think that is another poor CCZA (engine code) and blocked oil control rings on pistons

ok makes sense. Will faulty coil show up on diagnostic? Blocked oil control rings?? Should I be nervously sweating here??

 

The coil pack fault may show as a misfire fault and cylinder number if consistent enough.

 

The oil control ring problem could Edit: Would be unwelcome.  I would suggest you monitor oil usage over set mileage ASAP. 

 

If you pull all the plugs and take photos, especially around the business end of the plug, it may provide some more insight.  How much oil went in and over what distance?

Edited 7 June, 20178 yr by TheClient

When I changed the plugs last week there was a small amount of oil residue around the head of the plug. I put approximately 2 litres of oil in the car when I filled it but before that i'm unsure, All electric claim a service was done when I picked the car up 3 months ago but hadn't updated the service history...

How many miles you done since topping up two litres? And how many miles for all those 3 months?

Edited 7 June, 20178 yr by rayx

Was this car running OK before you put it to DK Tuning?

 

How long did you have it, ?

and i take it you were giving it some welly pre remap and decided you wanted more go.

 

Did it use oil pre remap or ever have misfires showing as the Engine light 'Emissions Control', or EPC light?

 

EDIT,

sorry missed the 2 posts above..

Edited 7 June, 20178 yr by Awayoffski

If you've got all the plugs out. Take good photos of all the old ones together on a bench with light background and post.

 

2L is a lot of oil. Unlikely anyone would have underfilled that much and the low oil level light eventually came on once gone. It has gone somewhere. But the question is in what Mileage and has your car missed an oil chnage if they didn't carry it out?

 

Maybe try to get them to change it ( at no cost given the uncertainty over whether it was carried out) and tell them you want to bring it back in for them to measure the usage as you think it may have a problem given how much top up was required.

Car was running ok. Had a celica before and found this to be less responsive hence the remap. No warning lights beforehand. Have read lots about remaps potentially highlighting unknown issues but not sure how true. Done about 2000 miles since I've owned it but don't know about the oil condition before as garage said it had been done so I didn't double check. :(
