Had my custom map done last week and did my service yesterday (pipercross airfilter, spark plugs, pollen filter and oil service)
Now at lunchtime I floored it in 4th and at one point it lost power, eased off and drove normally.
I thought fuel cut only happened on Stage 2 with a Intake and TBE due to the extra air and the HPFP not being able to cope...
:confused:
Trying to borrow a Vagcom to log the blocks mentioned in other posts but has anyone else had this with a stage 1?
Car is running 240bhp so thought it would be ok. Going to do the 3rd gear test (2,000rpm - floor it to 6,000rpm) and see if it happens again - if it;s consistent then at least I can log it.
Just hope it's not something I did when servicing......wouldn't have thought so.
Thanks

Could be a damaged DV

It's only about 2000 miles old..... :confused:

Rev D?

Try turning off your ESP and see if it stops matie :wink:

Rev D?
Yep.....car has been perfect up until today....too coincidental I did a service yesterday??
Was great with pipercross panel...though after oil and filter change and spark plugs this has happened.....
:sad1: :sad1: :sad1: :sad1:

Don't thkink it was trying to spin in 4th.... :wink:
It only cut midway (maybe further) up the rev range.

My reply didnt save dammit lol
Anyway, check that your sparks are all in securely and the coil packs are also snug on top
Its also worth checking to make sure the MAF plug is in properly and that the side air feed is snapped onto the airbox properly.

sh*t....can't remember connecting the MAF sensor back up :ashamed:
Leaving work to check now.

Nope sensor connected......hope it was that then.
When I chnage the plugs I nipped then up though not over tightened them. The coilpacks when on and I couldn't push them down anymore....do you need to use some force with them?
-
So the sensor was or wasnt connected :signLOL:
They have to be torqued to about 25nm
-

Whicc part is this? if it's the tube where the MAF is then it's on properly.
-
left side. ah kl

Sensor was on....will get a torque wrench and double check..
-
What plugs did you use also?

Got them from Edition_30_P
The ones that came out had three prongs.....the new ones had one.

Gen VW ones? I think thats what I have in mine same as this...

Just turn it off, i bet thats the cause 100%

Will try it as well..
Any reason why this would cause it?

Am I right in thinking you've had nothing but trouble from that remap by those people?

No, it went back for a tweak for more power as they initially setup it up on the light side.
Since then it's been great. Good power and nice delivery.
All the way home I was going into 3rd....upto 2k, then flooring it....must have done this and also in 4th..... nothing...was perfect. Just that one time at lunchtime.
Very strange.
-
Ahhh righto...
Any chance you could have hit a bump/oil/drain cover letting the wheel slip and the esc jump in?
-
^^what he said :happy2:
-
Could be lads...will test over the next few days and see how we go.
Out of interest, Paramount told me the other day that they write their maps for 95RON petrol for flexibility.
If they tweaked it again for 98RON would I see even more gains?
-
Yeah would defo see more gains, surprised it's not written for 98 to start with...

Will be on the blower tomorrow.......
They've only just started with the VAG cars as they've primarily Astons, Ferraris, Jags etc.....though want to get into the more mainstream cars.
They've done their Audi TT 2.0 TFSi and now mine, great lads and willing to tweak and try new things so will get them to have a go....
Thanks gents...

The GTi is a 97RON car as stock so I'd expect the map to be designed to utilise 97 at a minimum. Most will expect you to use 98/99 for best results.
But in answer to your original question it is entirely possible to get fuel cut with what you consider to be a stage 1 map. There aren't really defined parameters for stage 1 mapping so yours could be more aggressive.

Would it be a consistent issue or intermittent? As it's happened once and I;ve done power runs from 2k to 6k numerous times and nothing happening.
-
Well that's anyones guess to be honest mate. I would suggest that if you had fuel cut it would be repeatable.

Will keep an eye on it this week. Having some logging done this weekend by mb from here so see what happens with that.

I thought the TFSI was 98RON. Pretty sure that's what the fuel flap says. :confused:

You're probably right Ian :happy2:

Aye that is what the fuel cap says. I filled up earlier :happy2:
-
iirc it needs 98RON for the stratifying to work properly...
-
That as well.
-
I have of late noticed that at timed when I put my foot down there is a delay and then the turbo kicks in, do you guys think that this sounds like a fuel cut? I have had my DV replaced to the revision D model.
-
May just be turbo lag, i doubt, at stage 1 on your K03 that it would be a fueling issue if youve not fitted any other supporting mods Homer.
