Hey Experts !

I finally installed the colorMFA, the DV, oil catch can, etc... I've just tried ME7Logger, it works for a few seconds and:

Override sample rate is at 20... standard value.

Do you know what could occur here ?

Thanks !

Thanks.. lord knows... well it looks like dam dum daaaannnn "the input string is not he right format"

A total shot in the dark would be; an error id being raised as a return to a function which is supposed to be a number?

why not start with a simple configuration first.

I will try yours at l(a)unch !

 

[katak]

I'm still encountering the same issue... I played with fast / slow and other ones, always the same; I could have it worked for 15 seconds... while VCDS is always ok, btw I used and I made curves since Stuard does not like raw data :

Still using same site for picture hosting...

=> Well I changed the DV by a genuine one and it's much worst in term of boost, I could see that the small hose going at the top was not easy to tight, especially on the genuine where the tube lenght is shorter than the Forge one. If there was a leak on this interface, would it make this effect ?

Thanks guys

 

[Wak]

Something I havent done.....
Since having colour mfa I havent needed or tried to do any logging on my own car....

the colour mfa is reading a lot of VCDS style data that the dashboard didnt before, it may be clashing with the port when trying to use me7logger.

Can you turn it off with the reset buttonlike before, if you can try that and see if it works.

I do have liquid TT and it does appear to work fine with colourmfa also running but I wonder if it is blocking me7logger when you are trying as that is a more sensitive tool.

 

[katak]

Hi Wak, Ok I'll try this to see if that's better !

I have installed the Forge DV... Still 1600mBar as max boost hence there has been some degradation and it's not coming from DV, N75. Is there any debug I can do on the wastegate like tightening the screw ? (debug only)

Thanks

Ultimatley all the mapping settings drive out the final N75 value so, if you are at 95% then its asking for all it can give.
Next is to check for Wastegate crack pressure to be 5.5psi (on a k04 225) is when it starts to move, you need a pressure gun and gauge to check that.
Beyond that its a proper leak test
95% duty plus WG set properly plus no leaks should equal good boost profile.

If all the above is fine then I dunno.... it gets expensive because it starts to point to turbo health.... pull tip and see if it is free spinning although journal turbos dont spin like ball bearing turbos, make sure it is not dragging a lot.

1600mbar (inc atmospheric is bad) 1600 not inc, ie. 1.6 bar is ok, its what it holds..... 1.1 to 1.2ish bar is the range it should be in near redline, if not more, if all is healthy.

 

[StuartDB]

What lead are you using with me7logger?

It didn't work on my S3... something to do with k-line not being clean, even though vcdslite worked okay why it. And I am on my second ebay cable after 4 or 5 years. And sometimes going over a bump will lose contact.

Have you tried a different port on your laptop?

 

[katak]

I confirm that 1.6bar includes atmospheric, yeah I'm missing close to 1 bar... it's worst than several month ago.

I did not ake the debug of colorMFA but for the cable I bought it through the bay, I'll try this week some trials but I do think that turbo should be replaced, anyway I want to keep my car forever and assuming I'll make another 200k Km I'll be dead since I'm driving around 5k Km per year !

My only concern is to find a good mechanic in south of France... not famous for !

Cheers and thanks

Hello,

I'm discussing with a mechanic that knows 1.8T quite well, I might replace turbo in coming 3 weeks.

I have 2 questions for you experts :
- I can see on some websites that before replacing turbo you have to make 2 engine "rinsing" (correct term ?!) ?
- Do you suggest any other replacement aside from the turbo like downpipe ? etc ?

Thanks in advance

I Can only say you need to be certain its been properly reviewed, proper leak tests, proper logging to confirm what the ecu is doing and the leak tests to ensure you dont have a problem other than the turbo.

have you pulled the tip to feel the turbo spinning and play.

I have a customer that bought a new engine and turbo because he couldnt come back to me to review his car, he came back to me after still having no boost and I found a cracked intercooler in 10 mins.

His 1.8T experts removed the cracked front mount with the 8" crack on a weld front facing and staring them in the face and replaced it to do the engine and turbo swap.

Just hope you are confident on the diagnostics so far. :?

 

[StuartDB]

If you are going as far as changing the turbo, why not change the exhaust manifold and downpipe to 3inch. Don't get a relentless tubular manifold (or a Chinese copy) they all seem to crack. The #chinafold is a popular replacement but you want it ported and make sure it is the newer version from aliexpress. You will want to modify the dogbone mount with a powerful bush as the engine tipping will make the 3 inch downpipe hit the tunnel or prop shaft

Lots of turbo replacements are because of turbo failure, so the fitment instructions will include ensuring the pickup is clean and oil pump is healthy and oil feed pipe is replaced. And it is correctly lubricated before starting the engine.

I'd like to know if this is true when the turbo is properly braced as Ive heard of a few that are running fine.

The Issue I believe is that the OEM brace is precise and doesnt fit the turbo when aftermarket manifolds are moving the turbo by small distances and people have just decided not to use anything putting all the stresses of engine movement and exhaust movement (which is like have long leverage) into the Manifold as it becomes the weakest link.

 

[katak]

Thank you for your feedback, I have a rendez-vous on monday then I'll think of this project / issues, etc...

I have to admit Wak that I did not pull the TIP, I'm too afraid not being able to put it back there...
Meanwhile I'll make a leak test this week.

Concerning the manifold, I have found this:
https://www.aliexpress.com/item/4000179597129.html
=> It looks like some tuning have to be done which it not in line with project requirement since the mechanic won't accept this; so far I have to keep mine, perhaps a downpipe replacement is still possible with a quality one like 42DD.

Cheers

 

[StuartDB]

@wak my assumption was related to the heat, not vibration. Although, some people might have no problems (so no need to mention it on a forum), I have only heard of people getting a free replacement from relentless and that cracking too. I bought a cheap Chinese copy, but it was a rubbish fit on the head, and looked a real pain to connect to the turbo..

Yeah, that's a cast stainless steel 'Chinaford v2' I bought some carbine bits and widening the 4 tubes to the same a width as the stock one. And opened up the collector inside and lip. But it looks nothing like when Badger5 were getting them cnc'd.

Hears a video of porting with a drill..you can see a spacer too, I should have maybe done that.
