Hi,
Below is my logs from my 3.2Turbo, ( 85mm MAF) vs RPM. At first the MAF curve follows RPM but then it kinda flattens out? Is this normal?. I think Im sniffing around 350hp+ but that MAF value dont seem to add up to me?
Also added Lambda log.

1) post the actual logs
2) why not graph with RPM as x

Also log MAF voltage, MAP, and TB angle

Heres the real logs. I think TB% is there but not angle. "Think" i undestand why you want TB in angle, but feel free to explain. Is it because the value i see is only the requested angle?

Are both VE and manifold pressure constant? If not, what do you think? |

What version of VCDS is this? It has bizarre column names, like "Mass air taken in" and "Engine RPM"

It VCDS 409.1....I Tried to use Me7 Logger but it didnt work with my ECU Me7.1.1G ST10.. Or have anyone here got it to work properly? Well.. So whats happening here is that the curve looks like this because VE and the flow is not constant that makes sense right?  I just thought to my self that the curve deviated so qiuckly. But its probably the turbo that kicks in BIG time LAG |

It VCDS 409.1
Get the updated version. I keep having to dork around with ECUxPlot because old versions were all over the map with column names. None of the useful functions will work right. You can also try a snapshot http://nyet.org/cars/ECUxPlot/nightly/....I Tried to use Me7 Logger but it didnt work with my ECU Me7.1.1G ST10.. Or have anyone here got it to work properly? Unfortunately, no. Well.. So whats happening here is that the curve looks like this because VE and the flow is not constant that makes sense right? I just thought to my self that the curve deviated so qiuckly. But its probably the turbo that kicks in BIG time LAG If pressure goes up, should MAF should deviate upwards or downwards? BTW VE probably isn't changing as much as pressure. |

Maybe it's because you are turbo'ing a motor that has an ECU that doesn't support boost?

Hmm maybe you´re right... What ECU does United Motorsport and C2 use? Have they changed to a different ECU´s
Im open for advice.

PRJ can modify the ECU's for boost control, I asked the same question the other month. Have a look for R32 with S4 loom, etc.

Ahh Intressting idea i must say.. But im gonna stick to my ECU. This ECU have no control for the boost but im running manual boost valve right now on low boost. I´ll solve that issue later.
This ECU measures same stuff as the other ECU´s If i have managed to come this far i think im going to be able to make a really good tune for this later. I have the whole winter to tune this car.
So what im gonna do here first is to calibrate my MAF better then things hopefully will be better.
