Evening all,
Im in aid of some advice with my car
Back in June I had a full k04 conversion,cambelt,helix organic clutch,valve clean,runner flap delete, also I was running Revo stage 2+ then went on to Revo stage "3
this is the main issue Is what I'm dealing with, when Im on full boost it spiked@23psi then it backs off between 5500-6000k to 15psi then surged back up to 20psi and holds to red line
I thought that's not right so I phoned up I asked the question is this right, he said it's most likely to be the settings it's on to cause that issue, so I thought okay I'll pop up and have The settings looked at, he had the car 5 days he Phoned me up to say the car was running dangerously lean and the ecu is backing off the boost to protect the engine, the measuring block 001 was showing 24.6 enrichment on the lambda +25% is the max... so it was maxing out !
Am I right in saying when mapping a car your meant to look into these things to make sure it's running perfectly so they've either not bothered looking in to this when I first had all the work done or did and left it as it is and let me take it home on 2 separate occasions with this serious fault!!
Any advice would be helpful were I stand thank you

Sorry to hear you're having problems mate. All I'll say about airing this on a public forum is be careful. It could go one of two ways; they see that their reputation is possibly being tarnished so do everything they can to put the job right and restore their reputation, or they take it badly and fob you off.
I know you haven't specifically mentioned the name of the garage, but as this thread potentially rumbles on it's probably wise to be cautious in just how much you say.
All that aside, hopefully you do get it sorted without too many issues along the way. Fingers crossed for you bud.
-
Impho the garage that carried out the conversion should have made sure the car was running safely with the map uploaded and all specifications during and after were met before releasing the vehicle back to the owner, yourself.
Taking the wizzlet of you ask me.
Regarding your boosting issue and the revo map!!! The garage should have resolved this on the second occasion and not fobbed you off like that as it's their reputation on the line here. @AJP (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=11926) in all honesty mate, this company sounds like he ripped the customer off and now doesn't give a hoot about it. :fighting2:
-
Thanks @r5gtt (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=11199) all I just want for it be sorted so I can enjoy it again instead of spending multiple hours each night researching to figure out what it could be, and replacing parts, spending money to try and resolve this my self :sad1:
mate it's piss take when garages do this kind of thing and not try to rectify to issue and instead fob the poor customer off as I've had this with car insurance a couple of times and it's stressing to say the least!!!
Why should you the customer have to sit there for hours on end stressing and trying to find something you know nothing about and be spending more money on parts that may not even resol the issues :fighting2: argh drives me mad !!! :@
-
This is shocking, I'd ask them to sort out all the problems, or they refund you and put it back to standard.

Did they change the MAP sensor to the 2bar version??
-
Did they change the MAP sensor to the 2bar version??
Map sensor was left as it is because isn't needed for Revo software
Gti standard sensor is 2.5bar and ed30,s3,golf R is 3 bar

you sure about that mate?. @Dan_FR (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=9513) is the one who can help on this I'm certain.
-
the measuring block 001 was showing 24.6 enrichment on the lambda +25% is the max... so it was maxing out !
Ok block 001 is engine speed so I'm guessing the +25% actually refers to you fuel trim.
What intake are you using?
-

He is correct!
A stage 3 revo ko4 converted car uses the standard 2.5 bar map sensor.
-
If you go into measuring blocks 004/008 then go into 001 it does lambda and on full boost it's showing 24.6 enrichment if I'm correct so the ecu is making the injectors open longer to correct the lean issues? And Revo intake
-
could you log your fuel trim (block 032) and post the results?
You don't need to start the car, just turn on the ignition and log for a second.
-
I'll have a look now

just asking as the requested boost is quite high for stage 3?.

looks like it.
-

So on idle it's 0.9 and partial -6.3 ??

That's unremarkable so, is your actual fuel rail pressure keeping up with the requested value (block 230)?

So my specified is 129.99 and at points I'm dropping between 6-9 bar of rail pressure
-

What hpfp are you using as it sounds like your pump can't cope with the requested demand.
Do you have a RS4 fuel pressure valve fitted?

Deatschworks lpfp
Loba hpfp
Rs4 prv
I can email you logs over if you like ?
-
You haven't been treated right at all in my opinion. They should of made sure everything was mechanically sound with the car before carrying out any modifications. What I'd do is see who the top person is CEO, area manager, director etc and get some contact details for them if its possible. When I complain these days I don't even bother going through the little people at the bottom, it always seems like when someone way above them is involved they like to act right and do what they should of done in the beginning.
Good luck getting your problems sorted.
-
Thanks @Kai96 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=16484)
-
The loba pump should easily meet the requested 130 bar plus some more with the rs4 prv at all rpm range.
Two things spring to mind, have you logged your lpfp requested and actual values (block 231) and secondly are you sure your cam follower is in good condition?
-
Cam follower is spot on and @5,500 revs the lpfp
Specified is 4.4 bar and actual is 4.3 also brand new fuel filter too genuine 6.6 bar
-
I'd personally say you have it your all and the people that did this conversion need to resolve the issue FOC as this is down to them taking your hard earned money and not giving you the car back as it's meant to be and instead sending you off with a car over boosting and fuel not meeting requirements

@Paradox1 (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=9564) :thinking:

I hate joining topics when there are soooooo many posts......
First of all...... Did the same garage that loaded the Revo software do this conversion for you? They did not 'map' it in the sense you are thinking of and have simply loaded it to the car. They have also fitted second hand parts at your request and as such i doubt there is any warranty on any of the work provided. That being said they should have logged the car to setup the software and would then be aware of this issue. From then on they should have asked you what you wanted them to do.....
Secondly - Have you fitted the S3(K04) injectors at the same time? As you don't mention this........ If you are running the correct injectors and an uprated fuel pump then you would have plenty of fuel available for Revo Stage 3.
As was already discussed, do not change any engine sensors, you need to keep the 2.5 bar map sensor and standard rail pressure sensor too. How are you recording the 23 psi spike? standard sensor will only see 'up to' 1.55 bar of boost depending on atmospheric pressure at the time. Need to see a specified boost plot as it could be the ECu pulling back due to a boost spike, which could be down to something as simple as actuator preload
Can you post the full log up and not just dissected bits of info? You state you're only dropping 6-9 bar of pressure from requested, i.e. so you're maintaining over 120 bar of rail pressure....... if so this should be enough to not see anywhere near 25% fuel trim adaption. I'd be looking back to having the correct injectors fitted again.....
Full log of boost control, lambda control/request, fuel pressure, ignition timing, injection time, etc etc. Take a look here for help with the measuring blocks: http://www.goapr.co.uk/support/datalogging.php

@Dan_FR (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=9513) the garage did the full conversion and mapping
Here's my full spec
Bare in mind everything is brand new and genuine
So
K04 turbo
S3 injectors
Rs4 return valve
Loba hpfp
Deatchworks lpfp
Runner flap delete
BCS 3" power valve turbo exhaust
Revo intake
Apr Intercooler
I've got logs already but can't upload them dan ?
And I'm still running the standard 140bar rail sensor and 2.5 map sensor too
-
1 - sorry to hear this, surely can sit well with you for getting a conversion and map and it not being right
2- why did you take the car back if it wasn't right
3- Dangerously lean?? that was the excuse??? did you ask them what they are going to do to fix it as it wasn't dangerously lean when you brought it to them?
-
Dropbox or another filesharing service and provide a link? Or PM me for my email address and I'll take a look. When I get home tonight I can graph them to put on here too for others to look at.
I didn't realise you had it all done by the dealer. I would look to contact Revo HQ and point out you've paid for a full K04 conversion and the dealer has washed their hands of it. Revo tech support would take a look at the logs for you too so worth firing them an email.
Hard one to guess at the moment without logs as the car should have ample fuel with the Loba, Injectors and the RS4 PRV. Might also be worth posting the data on the TFSI Tuning FB group as there are a lot of very knowledgeable TFSI tuners/Gurus on there

Any advice would be helpful were I stand thank you
So just to depict it more clearly:
You had a regular GTI, you took them a box of K04 & other bits, they fitted it all for you, they flashed the ECU with Revo Stage 3 and sent you on your way?
Which parts from your list were already fitted prior to the K04 upgrade, and does this garage have a dyno?
I'm just trying to pin down the error point. Engines which have had a lot of parts put on at once can be tricky to fault find back to the offending part(s). I'm pretty sure something mechanical is amiss. It's highly unlikely the ECU programming is at fault. We just need to try and work it back.
The only thing my gut is tingling about is the aftermarket LPFP. Do you have the OEM one you could try, just to outrule it? Edition 30s don't need LPFP upgrades until way past 350hp, so not entirely sure what led you down that path?

So it was on Revo stage 2+ K03 gti before the conversion happened so the loba,Revo intake,turbo back exhaust, apr Intercooler, the standard lpfp was on there when issues was brought to my attention bare in mind I phoned them up soon after having the conversion done, telling them about this issue and they said it was the Revo settings I was on :thinking:
I was told by the garage it could be the lpfp struggling to keep up so it was replaced as a precaution but made little difference so after that I logged it again then sent them over it took about 2 1/2 weeks to get told the software was at fault :sick:
So I've been driving around with issue for 6 months!
-
Thats not good. So they told you what the (possible) problem was but didnt offer for you to bring it back to diagnose?
Have you contacted them to let them know youi've changed the LFP?
With all that has going into the conversion, plus mapping I think its a bit fair field to put it down to fuel pump without proper testing.
-
Just stumbled onto this thread by chance and sounds similar to your issues - http://www.mk5golfgti.co.uk/forum/index.php/topic,3242.0.html
It's something to do with an incorrect fuel pressure sensor causing exactly the issues you describe. It's a K04 car with Revo Stage 2+ as well.
-
I've read that @Pudding (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=10733)
it's possible but I'm not having any fault codes which is even more strange :thinking:
-
Had a look at the logs..... Have you tried turning the boost request down? Your boost is off the scale i.e. its consistently more than what the ECU can read. There's no way of seeing exactly how much boost you are running to know whether that is the cause of your fuelling issue.

the lpfp has been replaced so I doubt it's that and sounds better what dan mentioned but see what jhook replies back with.
