Maf hi STFT histo not working

[jhansen]

just like the title says

Im using sensor 121 (maf hz ) > 5700 and I get no data Maf lo works?

Also does anyone have a IFR And Inj offset table for a zo6

thanks

[SENS.121] is commanded AFR. [SENS.80] is MAF Freq.

Making changes to the top end of the MAF curve based on learned fuel trims (that come from narrowband O2's) is asking fro trouble. You should really be doing this with a wideband.

Im not using it for WOT it is for part throttle crusing and I was going to use the stft as a base like if it adds 10% at 6400hz I would add it all the way for a baseline the car has a jet maf on it also. I tried sensor 80 and it still doesnt work

by the way good book

[jhansen]

never mind it worked hit the wrong number

you wouldnt have any ifr and inj offset tables. this if for a 07 zo6 the table that I have doesn't look right. any help greatly appreciated

No but there are a few in the repository.

Exactly...you can only do this without PE enabled and in fiorced closed loop, just to make sure the MAF and VE tables are good.

You can only really do WOT with PE with a wideband. You can get WOT close by calculating by PE multiplier after you know the MAF is dialed in right, but reading the narrowband sensor under PE mixtures will not give you any accurate indication.

BTW: Do you have the right configs to do the MAF vs STFT logging? Just setting a pid in the histogram is not going to make it work.
