what could be wrong ???? few vag-com logs if it makes sence to anyone

[brasso88]

right done a few logs on my cupra, was from 2nd gear into third, dunno how good the data is just woundering if anyone can make out if anything is at fault from this like my maf or lambda, or can point me in the right direction to what i should be checking, basicaly my car is running like **** it seems to have lack off top end power when on boost and feels asif i have a misfire in the top end off the rev range, it only done this when i changed the maf for another 1 which i know come off a working car with no probs, if i put the old maf on it just keep throwing up fault code p1128, any helf or advice would be great as i dont have the money spare for labour costs to stick it in the garage atm

You need to take logs in 3rd from 1500- redline.

What car is it and what spec?

 

[brasso88]

well will give it another go 2moro, its a mk3 cupra, ko3s turbo front mount, forged valve and tip, cat back, cone filter and has been remapped but duno who by tho. what blocks on vag com are good to take readings off as i only have the free version atm. i know block 002 does the maf, but what other block if any could i read some data

 

[vroomtshh]

Blocks 002, 020, 115, 003, 031, 118 pretty much cover everything.

On that spec, it looks like your injectors are maxed out. Maf is very low but that's probably because you didn't run all the way to the redline

 

[brasso88]

Tbh I haven't looked to see what injectors ect is on it, I've ain't had the car long and also didn't get bigger all paper work with it, any way off telling what injectors and fpr is on it if u know what I mean?

 

[Chambers_CUPRA]

Youve probz got a 4bar fpr on it amd standard injectors on that spec

 

[brasso88]

right plugged my car in today and had a new fault code ive cleared code and it hasnt come back yet? do u think this could cause my running problems
16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit

P0130 - 35-10 - - - Intermittent

also did a log in 3rd hopefully its a bit better ran out off ? when it reads high on lambda is when it starts struggling for power a dies off and seems like it missfiring?

Check the 3 bolts on top of the exhaust manifold, the ones that hold the turbo on i bet u they are loose
Happens to mine now n then

 

[ibizacupra]

when your car is on cruise and idle does your block 001 sit at +25%?
malfunction in circuit error is the cause..
try lambda first, but I fear there is another electrical gremlin which will continue to cause this overfueling..

resistor mods being high on the *possible* list having damaged the ecu output stages..

not yet found a fix for this on the several ibiza's I have found this one

 

[brasso88]

Will check it on idle, it's still got the valves plugged in ATM, haven't put resisters in yet, and it was running lean before I changed maf.
