ibiza k04...gt28rs soon to be (PICS)

[h17och]

with n75 in the correct way? (the way it runs worst)

 

[h17och]

just done some logs...also think i now know the problem

where do logs get saved? cant find them on laptop

 

[ibizacupra]

vag-com/logs

 

[h17och]

ive found them but cant get them from laptop to pc. its not my pc!!! need to pop to my mates to get it on line and post them from there!!

i think its a boost leak but only at high boost! hence only doing it when n75 is in right way! it only hits 15 psi with in in wrong way and runs ok!

but with it the right way it hits 20+psi and i think its the higher psi that is creating a leak!?

on full chat in 4th it sounds like an old fasioned kettle whistling!?

also my duty seems to drop off at 2500rpm from 95% stright to 31% and at 4500rpm onwards im getting 0.0% (thats how it looks but its only in notebook as the laptop aint got excel so hard to read!)

does any of the above make sense?

 

[DPJ]

Yes,
Don't forget if you are trying to open them from Excel, you need to set it to look for .csv files, not .xls files.

 

[h17och]

wots the yes aimed at? lol

the laptop doesnt have excel (not mine)

I was agreeing with Bill (who beat me to the answer)

Do you want to email me the file and I'll convert it for you?

 

[h17och]

i cud convert it myself if i cud get it onto my pc but the laptop isnt online at my house so i will go to my friends 2m and email them to my pc and post them

does the duty explaination i posted above make sense?

 

[DPJ]

It does to me. I log 032 (fuel trims) with 118. 032 out of spec values will often point to leaks etc.

 

[h17och]

what would i see in 032 that wud suggest a leak?

QUOTES = Ross Tech website

You can check your current state of trim by using VAG-COM or equivalent to look in Group 032 in your engine measuring blocks. The first two fields will have percentages. The first field tells the fuel trim at idle (Additive). The second field tells the fuel trim at elevated engine speeds (Multiplicative). Negative values indicate that the engine is running too rich and oxygen sensor control is therefore making it more lean by reducing the amount of time that the injectors are open. Positive values indicate that the engine is running too lean and oxygen sensor control is therefore making it richer by increasing the amount of time that the injectors are open.

"Add" means additive trim, which is addressing an imbalance at idle. When the ECU is using additive trim, it is telling the injectors to stay open a fixed amount longer or shorter. The malfunction (e.g. vacuum leak) becomes less significant as RPM increase. For additive adaptation values, the injection timing is changed by a fixed amount. This value is not dependent on the basic injection timing.

"Mult" mean multiplicative trim, which is addressing an imbalance at all engine speeds. The malfunction (e.g. clogged injector) becomes more severe at increased RPM. For multiplicative adaptation values, there is a percentage change in injection timing. This change is dependent on the basic injection timing.

In general, an out-of-spec value in the first field (Additive) indicates a vacuum leak since it is mostly present at idle, when vacuum is highest. An out-of-spec value in the second field (Multiplicative) indicates a fault at higher RPM, and may point to a faulty MAF.

this is an ibiza ecu tho dave.
not as clever as your leon one

Ah, thanks Bill. A little knowledge is a dangerous thing.
Sorry Hooch

If your willing to try, connect one of your fmic pipes to a compressor and pressure the pipework with about a bar of pressure, you'll soon hear the leaks.

I made up a home brew tester consising of a plastic tub cover, a few plumbing fittings and a pump with a gauge. Worked well and found my leak.

 

[h17och]

hmm, think ill plug it into the compressor, i dont get a leak at a BAR tho so will need abit more

cheers for help guys

 

[h17och]

just so peeps can see how i mounted it

Glad you sorted it, is it even more of an animal now? Got to go for a retest!!

 

[Molehill_Mike]

Eventually! Good Lad!

So what stage is it at now!?
