Hi all mine a leon cupra 180 auq 53 plate got a medium fmic with 2.5 stainless steel exhaust straight through from turbo and also have got a k04-001 hybrid turbo currently running a stage 1 map and it pulls like a train in every gear. Have just replaced the standard injectors for bam 225...

No problem, hope it helps

Might help you a bit mate mught but but anyways ive got a 53 plate leon cupra 180 auq mk1 and my car had what sounds like the same problem as yours was very lumpy and juddery to drive, trying to cut out on me at junctions and also had EML on but cant remember the one fault code sorry but the...

Fmic fitted with all custom hard piping and sprayed the seat badges gloss black looks alot nicer

And in regards to the n249 removal the same companies have said that it is advised to remove / bypass for a stage 2 and also the SAI which i understand can be done with a blanking plate and a few bolts so might look at ordering the kit for it. Even r-tech have it on there website for stage 2...

Right turbos all on and sealed properly the bam 225 injectors are in and the limp mode is still continuing after 1.2 bar but no engine management light is coming on for it so unfortunately no codes to scan but have spoken to a few tuning companys and theyve all said that the stage 1 wasnt done...

Sorry for the late reply but checled all the pipework and is all fine no splits or loose pipes so thats not the culprit at least but the answer that keeps being given is that it wasnt mapped right and the restrictor at 1.2 bar wasnt taken off the engine so everytime it goes to 1.2 or above then...

sai **

Yeah will take a look tomorow ive got an early finish in work so afternoon will be spent checking pvc pipes under the inlter manifold and tracing pipework from SIA and checking its plugged then hopefully relax

Was toying with the idea of doing that to mine as when it had full diagnostic run before stage 1 two faults flashed up which didnt on my own diagnostic reader which were 1. Secondary air intake system fault 2. N249 fault Hence why i removed the n249 as was advised to either replace or remove...

Brill no worrys mate will have a look either tonight while its still light or tomorow after work.

Ive got a 180 LC and IMO mate i havent really seen any difference but then again the car keeps going limp on me so once the restrictor is sorted and i have a little play i will post and let you know

You hit the nail.on the head there mate thats exactly what its doing on the boost gauge its going up to 1.2 psi then dropping and suddenly no boost untill i turn ugnition off and back on have heard it could be were its been mapped stage 1 that the restrictor hasnt been taken off or changed so...

So turns out after replacing the n75 that wasnt wvwn the problem the car will boost fine through the gear range and then randomly, could be after 5 or 20 mins driving, will just drop off and ill have no turbo at all kind of like a small limp mode feature but got no idea what it could be causing...

As soon as the turbo goes on its having a stage 2 map done with fmic fitted so should have a problem with overboost. Would i need uprated injectors and possibly a 4 bar fuel pressure regulator to go with ? Sent from my SM-G900F using Tapatalk
