iv not head of a MAF causing over boost, its normally either the N75 (most comon) vac/boost leak (very common) or the MAP sensor (not that common un less you have a remap AND played with the actuator)...
but VAGCOM will show you the way
but VAGCOM will show you the way
According to vagcom my next door neighbour has a ibiza so knocked on his door!
Yes it is the map sensor code or intercooler... It has had a remap and the turbo and actuator was replaced with new ones.
How you mean not that common unless you have had a remap?
Does this mean the map sensor will need replacing? If so how hard is it to fit a map sensor???
You guys really help, cheers

i love being rite lol
basicly the MAP sees your boost, if it goes over a set PSI (i think its about 12PSI in a standard set up) it sends a signal to the ECU to bung it in to "safe" (map sensor will send a 5w signal to ecu once the limit is reached) with out wanting to sound bad, the remap hasnt been done fully correct...
normally the mapper will remove or change the limit to keep it safe.
a few things you can do, if you like the power you have and you have a boost gauge so you can keep an eye on things you can do a little mod on the MAP sensor, it involves putting a diode (like a resistor) in to the wires so the map sensor can only send a max signal of (for example) 4.7w meaning the car never thinks its over boosting, the n75 and maf can still keep things in check meaning boost still controlled and air is still being seen so no over/under fueling... i had to do it on my old LC as i had shat loads of boost issues this fixed them all BUT i also ran a Manual Boost Controller so i could set the boost to a set psi.
another option would be to set the actuator up (undo the 2 10mm nuts) as to me it sounds like its wound down to much, at oem spec the bottom nut should have 12-14 threads to the end of the rod (i think)
## personaly i think this is the issue as not many places set them up correctly and can cause propper fudging up of the turbo!!! best put to oem and left alone (rich coming from me lol)
what N75 are you running?

I am running a standard n75 and map sensor, I have been doing some research on here and some people state that running a 3 bar map sensor works and others say no... People also say that the diode trick works but if its running dangerously the limp or safe mode helps you from damaging the car any further.... This is a learning curve. Where do you get a 3 bar map from, do you think that will help?

it has been scanned dude he said its the map sensor...
i dont know where to get the uprated map sensor from, cant see it being cheap though
personaly i would check the actuator, a lot of places just cuck it in and do the nuts up, you need to check how many threads are left from the bottom nut to the bottom of the rod...
also as im not 100% check how many are from the top nut to the top of the rod...
i really think this is all that needs sorting.
doing up the nut gives a little more boost but can cause over boost (and its not good overboost) if the nut is wound down to much the waste gate wont function correctly and can cause propper issues with the turbo
before you start spending on map sensors look at the actuator!!!!
