I had a MAF error few weeks back which was cleared and has not returned since. Is a reading of 10.7g/s at 3k revs standstill correct? Or is my MAF on it's way out?
Cheers,
Chris

Theses are some of my readings from 4k to 6k full load. How do these look?
RPM Inj. On Timing Mass Flow g/s
4440 150.4 143.28
4840 155.6 144.86
5240 149.6 147.06
5560 142.1 152.33
5880 133.8 144.83
Welly - Could I email you the full log which has group 115 and 002 for the quick test run i performed for you to cast your eye over a bit more? Quite worried i've not been reaching its potential for quite sometime now
Yep, no problem, I'll PM you my email address.
Those airflow figures sound really low to me. especially for a mapped S3!
Even without going to the redline, here's a tiny extract from the one log I could find on my work PC.
This is a ko3S turbo too, not a ko4.
RPM Airflow (g/s)
4120 150.07
5080 173.75
5840 186.39
6560 187.15
So that's just an A3, and at 5000rpm it's making almost 20g/s more than you're mapped S3! something big time wrong there.....
RPM Inj. On Time Mass Flow
TIME
STAMP /min ms g/s
165.28 5600 19.27 194.69
166.48 5840 18.86 199.25
167.68 6080 18.04 198.92
168.98 6320 16.81 194.42
170.29 6520 16.4 189.42
171.49 6680 15.99 191.64
OK, looking at that log, the airflow does look to be down, but it's difficult to be sure because it never gets to redline, and all the bursts of acceleration are short.
If you can, go out again and log block 002, 020 and 115. Timing pull (020) is a useful block to log because it gives you a better insight as to what is going on.
Try, again if you can, to do a several full runs in 3rd (or 4th if you are brave enough) from 3K all the way to 7K. Nice log logs are easier to gets useful info from.
I still want to know why I got 186 from a standard car.
Yep, it's got dodgy MAF written all over it....

OK nice one guys!
Will the below part be OK or should I get and OEM one direct from Audi?

If the maf's tired wouldnt the fuelling be all over the shop though?
Running lean will cause timing pull?

Getting my mate at Audi order me a new MAF....Discounted parts :thumbsup:
Will then do another log to see if the MAF readings have improved!!! Fingers crossed
