Ok, I received it and installed it but i want to wait a few hrs so I don't wake up the neighbors. Then I will post logs.
here is the new log with the new maf installed.... still running like complete garbage. It seems like my biss screw does nothing until it is in far enough to choke it off. So here it is. Maybe you can make sense of whats up.
Who's ECU are you running and do you have bit 2 of periphery 0 switched off?
Notice how your narrowbands aren't cycling?
I'm also noticing that your airflow/ load numbers are really high. This probably has something to do with having the MAF mounted in blow thru or the MAFT Pro settings.
I'm running Jesters.
Bit 2 was off..... I'll turn it on and give it a go.
I will double check the maft settings. Its just the regular maft with the dials not the pro.
You're gonna have to get that airflow signal down to about 25-35hz at idle in order for the trims to actually function or set the trims to work in the airflow range the MAFT reports.
Maybe set the MAFT to larger injector size or just dial back the low knob.
You're running stock motor and cams right?
stock motor and cams yes. ok i will try larger injector function.
ok here is what i came up with. As far as i can tell none of the adjustments change the hz reading.
Which table am i looking at for that?
There aren't any tables on the MAFT to adjust the HZ signal. If none of the knobs or dip switches on the box will bring the airflow number down then you're gonna have to calibrate the intake tables (MAF scaling, MAF adder and MAF Smoothing) for this.
So you're getting 80-90hz at idle and your fuel trims are trying to take away as much fuel as possible this means you have to lower the numbers in the intake tables in that HZ range. Start with lowering the MAF smoothing number to be 10% less than the number that's there in the 80-100hz range. If that's still too much, take away another 5% and increment down like that. I wouldn't be surprised if you have to lower it as much as 30% before your idle gets down to a normal level and the o2s cycle.
FWIW this isn't an issue when the MAF is setup in draw thru.
