Maf issues
I have a factory supercharged V6 and am trying to work out how to alter the maf tables to work in with a enlarged maf as you would know if you run a larger than stock maf and don't tune the car to suit it then you will in time burn out your auto the issue im having is i am unable to alter the tables by the amount i need i have enlarged the maf to flow 50% more than stock so i figure i would need to increase the maf table by 50% to reflect this the only issue is it only allows me to increase it by approx 10% am i doing this in the right area or have I totally missed the mark ? also is it possible in some way to increase the maf table by more ? please keep in mind when I say I its more my mate and i he knows allot more than me in this all but doesn't have much time to get online these days so any advice is appreciated and please make it as ill be able to relay to him thank you.

Re: Maf issues
ok i had a little play with the excel maf tables when increased by 50% the actual new table gps in the maf table #8 read #num! so im asuming this value is to high for the memcal to handle ?
Re: Maf issues
50% is huge! how big is your maf?
edit: forgot to mention... if you are flowing 50% more than stock, stock code will max out its internal variables well well before you hit that. the only code that wont max out the MGC is kalmaker.

Re: Maf issues
Jayme's right, your most likely to max out the mgc at 1000mgc in the midrange, as max torque and max mgc are at the same point.
This has been covered in other posts also, have bit of a look around a do some reading.
The max value for the MAF I think is 512 grams / sec, if the values are higher than this you will also max out the MAF tables.
I have heard of people getting in excess of 200rwKw with the stock MAF.
If you're getting significantly more than this, it is now time for kalmaker as there are currently no modified operating systems around that I am aware of.
