Mk5 gti pulling alot of timing with stock software !!!why?

[Trishen94]

Yes I have tried the search option found no1 has pulled timing with stock software all were software related so here goes my story

Hi guys so I'm having alot of trouble with my mk5 gti it's pulling bad timing sometimes -7.5 sometimes -7.0 most of the time -6.5 on all cylinders... it has factory software on it why is it doing this
Car has minimal hardware ...cai ,dp,exhaust ,pcv block off...
I've changed :
cam follower , plugs I'm now using BKR7EIX I've changed the coils also to another original set see no diff from the old ones I'd understand if I had software on the car and it done this but I don't... I do have wmi on the car and when it comes in there's 0 timing pull but with stock software there should be 0 pull without wmi so I don't know what else to try can some1 help me out here plz

Thanks in advance guys

bad fuel quality and intake air temperature play a factor towards pull which is possible.

With the Crap fuel that we have in SA you will always have timing pull.

There are a lot of factors that affect timing pull as i stated in the Plugs thread you have.

Intake temps, fuel, spark gap, blow by gasses etc etc. The reason you see 0 when the WMI kick in is your are cooling the intake temps down and your mix affect your AFR ratio as well.

Drain your tank of all old fuel. Buy 20L of Racefuel and flush the system with a few L then re log the Car again and you will see a massive amount of difference you will see by just uping the Octane rating of the fuel.

Easy fix is to Run NF octane booster on your normal 95 fuel and you will see a lot less timing pull already.

So bro this is like normal ? To see this much timing pull on a stock file ? What's gona happen when I load a stage2 file onto my car ? Tank clean will be done this weekend...but 1st let me change the fuel ...im currently using bp 95 let me try sasol 95 and see what happens ...what fuel do u recommend bro ?

[WeirdSteam]

Its normal for most modern cars to pull some timing the oem system is designed to monitor alot of parameters and adapt/adjust as required based on certain things.

You will have to shop around for fuel i cannot recomend fuel stations there

Where i live in CPT there is only a few that i use. (Non are Bp)

I dont use any station that is not very busy...... Old fuel..... Do some research on fuels, spark plugs etc etc it will give you a better understanding on why your car is pulling timing.

I am no expert on any of this i am not a tuner either, i have learned a few things based on expierences i have had and research i have done on this specifically.

As mentioned before, there are many reasons why the car would pull timing, even the amount of passenger weight would play a role. Once you do software, it would be a lot better because remember *most* tuners will write a custom file for you based on our weather climate, fuel quality, altitude etc

I logged a Ed 35 mk6 gti and in stock form it was pulling -9 at one point after wards advise was given to change plugs, as they weren't changed at the previous service, but the logs then showed a max of -2

Is the car running fine with no issues?
If yes, stop worrying about timing pull and just drive the damn thing.

[Titleists]

It's not normal. It's suppose to be 0.

Log the following:

Air flow
Fuel pressure
Boost pressure

Yeah, What he said

[Trishen94]

Ok bro so 1st il change fuel and see how she goes hopefully another garage has better quality fuel ...also let me see if I can get the software done next week...
I logged the intake it is abit low only flowing 158g/s but then again it's a stock file ...fuel pressure is fine 110 108 109 ...boost is fine +-1 bar

[panic-mechanic]

Timing pull on a stock file is not that abnormal. Our fuel sucks.

[Trishen94]

Hi panic ...so I shouldn't be pulling of my hairs like I am then coz I see a few guys say it's almost normal to pull timing but is it normal to pull -7.5 ? that is alot hey what do u reckon ? If it can atleast come down to -3 I won't mind coz it is very hot in jhb nowadays...

[panic-mechanic]

Ifnit goes outright to -12 you have some issue. -7 not that weird on a basically totally stock motor. If you have a look at intake temps and you see 40+ degrees trust me it is going to pull timing.

[WeirdSteam]

Yup like i have been saying.... Normal.

Panic knows what he is talking about and i have also seen it on my logs.

If we have a hot day 30+ deg i have pull of around -7 as well. The only way i have been able to get it down is by adding an octane booster in the fuel.

But its very low on my worry list as its not really affecting my normal day to day driving.

I keep a bottle of NF to add for very hot weather weeks.

If you add octane and it reduces then everything is normal. The temps we have been seeing of 34-38 makes every single turbo car out there pull timing.

[Trishen94]

Ok so time to stop busting my balls lol ...luckily I have wmi and it brings it 0 maybe instead of a 50%meth mix il run a 60% meth mix instead of octane booster that should even out everything until I do the software in a few weeks time

How would passenger weight cause timing pull?

[panic-mechanic]

NO. Leave the WM at 50/50. Adding more meth is not a magic fix and actually adds other issues. If it goes to 0 what more do you want?

[Trishen94]

U right about that panic lol ok il just leave the car as it is from today I think that's the safest thing for me to do....not sure about that passenger story also curious ...maybe panic , wierdsteam or dieter himself could answer that 1 for us ...i know when we race we prefer the car to empty due to safety and weight issues could be more weight =more timing pull I don't know let's wait for the seniors to answer

[panic-mechanic]

Don't fix what ain't broke....

[ALRoN73]

It's not normal. It's suppose to be 0.

Jetta2 says otherwise?

[Trishen94]

Right about that panic not even gona open that bonnet from now on lol

Loading a proper tuner map could actually fix your issue.

also, How would you know your car software is stock if you dont have it from brand new? ever dyno the car? whats the car currently boosting?

Can I suggest you log the car and post your readings here.

[Trishen94]

I have logged the car but I don't know how to post the logs via my cellphone into the forum

[ICE King]

It will help us to help you , its going to be tricky trying to send it from your cellphone.

Do you perhaps know how much the car is boosting? was that timing pull at WOT?
