hello, yesterday mount 3 "maf and 384cc / min injector, from a leon cupra r (bam).

I made the basic changes to operate these two changes, I applied the krkte and kvb for fueling, and mlhfm and mlmax for maf.

the car feels good, but I lost about 15-20 g / s reading at wot maf.

Fueling the demand is close to the ecu, although this a little idle rich. I tested the krkte value of s3 / tt with (bam), and is poorer, not really because leon cupra krkte uses this value using the same injectors in all cases. you may use another fpr audi ?.

well, I would like to help me with this, because I want to adjust these changes before putting the new turbo I'll buy. in logs before changing this, getting readings of 185g / s at 6800-6900.
maf sensor in both are the same, that has left me thinking, and I've read that there were iguales.puede might not be correct for this maf sensor housing ?. I tested the two sensors with similar results.

thank you for your help

In theory as you are running an 049 maf sensor which is wideband it should be ok with the the bam r mlhfm map.

personally I wouldn't worry too much about the maf readings, as long as you understand they relate to Load and therefore are used as axis for the maps then it doesn't really matter as you then can compensate on the maps when you tune and log..

Now if the reduction in maf has come from say restriction in the maf housing then it is worth looking at, but then its a physical thing not a map issue.

worth checking  MLOFS is the same , which I imagine it is and if it really bothers you then scale the Bam map up so it matches your old maf readings..

Hello, this morning I have been researching the subject a little, I went to my dealer parts, and I had in hand an original bosch maf lcr / s3. We have looked at the sensor and effectively is the same in my original maf, and the lcr I buy used. therefore there is no doubt that the difference has to be for some wrong map, or is it really is reading less. What do you think? Thank you

resolved! I returned to clean the filter and I cleaned the MAF and read as before, finally I used the krkte audi s3 and now works much better. Thank you
