i now have some logs, please could somebody look at them and see if that tells me anything thats wrong, i dont know what im looking at! :signLOL: i have boost spikes through every gear on full boost.

Hi Joe,
Email them to: sales@pdtuning.com and I will convert them into a nicer format to view, I have 10 mins spare waiting for a customer to arrive.....
-
Ive emailed you the whole files, cheers pal.

Your throttle angle looks like it isnt WOT all the way through the run, when I logged mine I had 99.6% all the way through if it was planted.
Your peak air intake equates to about 227 bhp, assuming you dont have any modifications then thats about right for an ED30 intake air /0.8.
And mines a standard K03 and once the turbo has finished spooling, you generally see a peak of boost above specified, and I guess this would be greater with a K04 turbo.
do you have a longer run from around 1700rpm upto the redline?
-
il upload the whole file,
the car is stage 2+
something is very wrong somewhere!
-
Post them up mate and I will have a look
-
Joe, when you did these logs with Ben, di you have your foot planted to the floor? As the throttle angle isnt right if you did it should be a constant 99.6% this could be causing the strange boost, as the ECU will be thinking you keep on backing off. I know you can do a throttle body alignment via VCDS, not sure if this might help? from memorry there is something on the ross tech wiki about it.

Hi Mate, its goine hectic, will take a look later for you.
-
interesting.
Ben did the logging with me in the car, il give him a call now, i cant post the whole thing, can you (rich) and KRL please PM me your email addresses and il send you the excel sheet.
-
Hi Mate, its goine hectic, will take a look later for you.
OK thanks mate.
-
DUUUUUR!!
The log i posted wasnt even a run! dumb ass.
Il send the run to KRL and Rich then post it on here in the original post.
-
original post now updated with proper logs. :smiley:
-
Just replied to your email Joe - you were not WOT for the run :sad1:
-
Yeah the throttle is only showing partially open, and isnt constant, just looking at what you have posted above. If ben had your pedal in the carpet then think it could be worth doing a throttle body alignment as per my earlier post!
And if that is just 50% throttle the figures actually look rather good 200g/s divided by 0.81 would be in the region of 247hp at half throttle :grin:
Also the boost looks fine to me, from the logs ive seen of mine and others you always see a peak at the maximum actual boost, and then it backs off. Importantly it is at or just above specified so looks to be fine. Do you have any further raw data happy to chop it up for you if there is more than one run for comparison.
-
so what figure\'s would you be expecting at 100%?
who knows how to do a throttle alignment?? am willing to travel!
also will this cause the boost spike?
do you think this would need to be re\'aligned after a engine conversion?
-
Ok very strange....
Even though VCDS says you were not WOT your boost graph looks like you were and is not showing spikes. Also your boost is constantly exceeding specified after the turbo spools:

Are you running the Forge Actuator?
Something is not quite right here as you should not be boosting like that unless you are WOT...

TBA taken from RossTech Wiki:
Drive-by-Wire (DBW) Engines using KWP-2000 or CAN
(These are engines WITHOUT a physical cable between the accelerator
and the throttle. Check to see if the engine speaks KWP-2000 or CAN by
looking in the top left of the Open Controller Screen. An example of a
KWP-2000 engine controller is the 2002+ B6 Audi A4 1.8T. Some examples
of CAN engine controllers are the Mk5 Golf 2.0T FSI)
Turn the key on but do not start the car.
* [Select]
* [01 - Engine]
* [Basic Settings - 04]
* Group 060
* [Go!]
It should say "Basic Settings: OFF" on the top of your screen.
* Click [ON/OFF/Next] to turn on Basic Settings.
It should now say "Basic Settings: ON" on the top of your screen. Once
you do this you will see the top right display say ADP RUN. The TB
adaptation is being done as soon as you switched basic settings on.
You will see the values change and hear the TB cycle for the first few
seconds then it will stop. Leave it in Basic Settings for about 30
seconds.
* Click [ON/OFF/Next] to turn off Basic Settings.
It should now say "Basic Settings: OFF" on the top of your screen
* Click the [Done, Go Back] button and you're all set.
Be sure not to touch the accelerator and make sure the engine is NOT
running when you do this!
Special Notes
* In some engines, before doing a TBA, it may be necessary to
cycle the ignition off and back on after clearing faults.

i dont have VCDS,
Do you think this could be the problem?

Ok very strange....
Even though VCDS says you were not WOT your boost graph looks like you were and is not showing spikes. Also your boost is constantly exceeding specified after the turbo spools:

That boost is extremely low, so ties up with not being at WOT.
-
Joe did you and ben doing any runs looking at what the fueling system was doing?
And according to the wiki link that I posted above, if the ECU has been removed or the battery for a prolonged period of time then you need to do a throttle body alignment, also says if the pedals are replaced, and I guess you still have your original pedals so think the alignment would be my first port of call.
Think Darren was offering his VCDS services? And get some logs as per the APR site so you have all the info you could require.

No its not mate - I deducted atmospheric pressure = 1 bar.

that explains things.

think il get morty to do this then, and get some logs.
get my car back tomorrow so will give him a PM. :happy2:

Comparing these graphs to Mike_TFSI http://www.mk5golfgti.co.uk/forum/index.php/topic,15408.0.html (http://www.mk5golfgti.co.uk/forum/index.php/topic,15408.0.html) which is the only other K04 logs that I can get my ands on (he is running stage 2+ APR the boost is comparable, but mikes show a WOT, but the engine loading on joes is ~140% where as mike, with the supposedly less agressive APR map is showing upto ~190%.
Anyone know what the engine loading value shows? Could this point to a lack of fuelling for the boost level? as air is nothing without fuel to oxidise? :smiley:

just had this responce from REVO....
\'Hi Joe,
it looks as though that log is at partial throttle. From the data you can see it’s massively overboosting at lower rpm then is trying to stabilize throughout the rev range. It could be due to any number of things; faulty boost control solenoid, DV, or possibly the actuator not set correctly. To name but a few.
Unfortunately we can only take educated guesses at issues by just looking at data-logs, I’d get it booked into someone that’s used to dealing with engine conversions and the TFSI engine to have it looked at and setup correctly!
Best Regards,
Kev Hall\'

Joe thats the best piece of advice youv'e been given mate! :happy2:

going to see morty tomorrow night and let him do the throttle, car is booked into statllers on monday. They seem to know what there doing.
-
Hope you get it all sorted soon mate, it's probably something stupid! :happy2:
-
Sorry to drag up an old thread, but did you find out what was causing the problem, as my car is doing the same thing
Thanks in advance :wink:
-
IIRC it was the connection into the ECU wasn't correct, the blocks in the plug were pushed back or something, Stattlers sorted for him :happy2:

Thanks Gaz, not the answer I was hoping for :sad1:, been trawling though all of his old posts trying to find the answer :rolleye:
