hi guys been struggling to get this figured out, done around 1000 miles on my engine iv just rebuilt, now its getting cold the cold starts very rich. it revs to around 1200 and a second later it sounds like it misfires in till I blip the throttle the then it can happen again in till the revs drop down to normal operating revs

KRKTE correct
MLHFM correct
TVUB correct
FKKVS correct

iv tried  adjusting the lower temperature lines in
KFFWL_0_A
KFFWL_1_A

I copied down the correction from 15 degs to the lower two lines as it was running fine in warmer temps

its very frustrating to solve this because I have to wait ages to let the engine cool down completely

nothings really working, car runs great while warm.
I don't like this issue because I think its creating oil/fuel dilution

so any suggestions would be great, I don't have an aux wide band sensor.

thanks 

Correct according to? Logs help

yes logs do, but im asking for a suggestion to what im missing out and not asking you to view my logs
thanks

Your calibrations obviously are shit. You say you have all relevant fueling maps set right without any data to backup your bogus statement. You ask what's wrong and I'm telling you. Good luck falling into the black hole with the other 99%

idle fuel trims are -2.6
partial are around -2.4

im speculating they are correct as they are copied from a good file, from a reputable company

im a grown man , and work for a living please don't talk to me like im some kind of child.... iv spent the past 2 months fucking around with my engine, I machined out my own turbo also

If you have to play with cold start maps for ev14s 550s with a maf'ed car your tvub and Krkte are not right. I do mafless cars with larger injectors then these and barely ever need to change. If you think copy and paste from one software version to another from a file someone else made is the right way you got a lot to learn.

look I don't need to be good at this I just do this for a little fun, so I don't want to fully understand the calculations, yes im probably a retard in your eyes but I don't care as iv completely rebuilt my engine every single part

so how do you know for one second I have not messed something up like bent a valve , you've just out right slammed my file. because your probably a troll

Good luck. You're going to need it

Hero member Yea right

How many cars have you built anyway?

I don't do this for a living I'm a CNC machinist so I can talk you equally stupid about that

Why are you getting so offended? Take a chill pill, Marty is actually a respectable member here. Ev14's 550 should not have a cold start issue at all. If your trims are in spec why don't you take a look at what your sensors are reading before you start it? Like coolant temp sensor? Start with basics. Nobody is here to bash anybody, this isn't the s4 community.

Hi I'm not getting offended, thanks I will have a look at that... I'm seriously frustrated because my full forged build has cost me many thousand and it's still a Rusty skoda

If you aren't willing to put in the effort, the results will not be good.

Sadly getting injectors right is not that hard, compared to what is required when really tuning.
I have to agree with the other guys here this i just rebuilt my whole engine blah blah. I mean
thats great but some of us are not that impressed cause we do it everyday, and honestly
the whole I'm a machinist thats afraid of math thing just dont jive for me every real machinist
I've ever ran into loved math more than life.

Trolls don't get +47 applauds.. People who are willing to help you if you just shut up and show some respect to an individual you could potentially learn a lot from but you obviously have way too much pride with your stolen file and being a grown man and all that jazz so you don't see that the fact Marty even took the time to respond to your post shows that he was in fact willing to help you... People like you are the reason for -29! ::) When you come to our forum and your asking for help but you openly state you aren't willing to take the time to learn much, then you act like your too good for logs or something? because you work for a living and your not a kid? well your not acting like it...

Just suck it up man and realize if you openly state you dont want to learn the technical jargin, rather you just want to be spoonfed some answers (with no logs) then your going to get some heat for it. But be patient and be respectful and I bet you'll soon find thats a better way to eventually get what you want.

Obviously not amazing like yourself then and need guidance it's my first car Engine build

See this is why I hate even asking for help all you get is bullying by know it all guys behind a desk, I know fuck all and im admitting that.

My maths is completely different to ecu maths also, I work mainly with geometry calculations, and thank you for the slag once again. 

I'm deleting my account now because I can't take the the bullying, I feel really upset reading your comments and very depressing

Well you can't delete your own account can an administrator do this for me I'm no longer interested in this community thanks

I wonder where such people come from. I genuinely do.
Good riddance.

you can be a great CNC machinist, masterchief, astronaut, kung-fu panda etc
but this make no sense

Many more then you ever will. Currently I have a 2.7 s4 with a fully forged rotating assembly on my engine stand currently with two gtx2863's strapped to it . A mk3 2l 8v I'm converting to me7 and turbo, a mk4 fully built that almost completely assembled gt3071 . "Building" an engine is adult Legos. My 7 year old nephew can assemble a engine

Amen

Is this real life?

 ??? This guy...

And see!? people like you are the reason for -29!! lol he left me with a -1  :P

I mean the audacity... Marty was simply showing him some good ol nefmoto hospitality... You want answers then you just gotta realize someone might give you a hard time in the process.. But at the end of the day, whats more important? getting an answer to your question? or your pride?... among a group of individuals you dont know and have never met personally?...

Oh well... Obviously wasn't going to benefit the community whatsoever anyways  :-\

I still want to know what was wrong with his car.

ah! good man  :)

dude who in the hell hates you so much!? I went to applaud you for being genuine and said to myself "is it even worth it?" lol

I was only testing to what kind of people are on this and im not impressed, is this not supposed to be a community? Anyway it was pipe that had come off considerably but could still make boost with my massive hybrid turbo.

And I have an engineering degree to you "afraid of maths guy" hahaha

Me?
Honestly I don't know. I guess I'm a shitty person for something. I have a dirty past that I'm trying to clean up for the past couple of years. I chose not to change my account so I'm reminded of how shitty I was and how bad I suck at tuning. Just trying to learn like you guys, and unconsciously tick nyet off with my pure ignorance.

haha awesome.

Hey OP, you got logs yet?   That part is not hard.  Post a log and everyone on this forum will bend over backward to help you.  Don't believe me?  Try it.

Your calibrations that you ripped off from said "reputable company" may in fact be good, but you might have a hardware issue too, and logs will help diagnose either situation.
