so what does the MAF smoothing table do?

 

^ I also am interested

 

okay I did a quick pull and my AFR are down to low 10s and they taper to 11.
my fuel table is set to 10.0 where boost is present.
too much fuel right when i floor it and the car is slow at first

but my boost was only set to 7-8 PSI, i'll raise it to 10 and see what happens, of course it'll give me leaner AFR

also, mitsulogger isnt logging the load right!
i know this because i rescaled both my fuel / ignition tables to 120 load and when i looked at what my ignition timing was hitting in my logs and compared it to my ignition tables, it was hitting the ignition values i inputed under 120 and in the same RPM.

i'll rescale my load tables to 130 and see if it hits that at 10 PSI

 

^ right on! Mind sharing what you have your maf scaling set to? I noticed that mines looks different from the other post in this thread. Mines starts around 100ish then increases??

 

oh also what about the injector duty cycle? did it go up or stay the same?

 

im using the values that senate used in his MAF scaling, except on mine i only changed from 500hz and up.

since its so rich when i floor it, i'll make changes to 600hz and up and see if thats any better

IDC did go up, but i am having a brain fart and i forgot the formula to calculate IDC.
but my IPW (injector pulse width) is now hitting 19.968 compared to 15.6

 

ya i noticed when i floor it I see about 9ish afr and it really bogs out. Prolly can tune that out in the fuel maps tho cuz its under high load in lower rpms when the turbo isnt spooling hard. shouldnt worry bout touching it in the scaling cuz itll affect everything not only throttle dip in i think

 

my IDC is about 70% for 370cc.
looks like i need to upgrade soon

you should not have any problems with your 440cc

 

You changed the lower maf scaling also to match senate's also right? Hows your fuel trims on cruising cuz i noticed his is higher than the stock scaling so you should be pretty rich i suppose right? But then again the ecu will relearn over it so i guess it shouldnt be a problem...

 

i left everything under 500hz untouched. i have my fuel trims dialed in (finally) and i didnt want the MAF scaling to affect it, so i only changed WOT

fuel trims are a b*tch to get right

 

you used the injector scaling and injector latencies to adjust for the fuel trims right? or did you somehow get them correct with the maf scaling?

 

Yes I used scaling and latency to get my trims as close to zero. I've been doing it all week and I finally hit the spot.

So I turned up the boost (1/2) turn on my MBC and that put me to 9psi.
AFR jumped to 10.5 on 2nd gear roll from 3k RPM and tapered to 11.7 AFR by the middle of third.

I noticed IPW tapers down... How do I keep it steady throughout the gears so I get a smooth AFR?

 

at what rpm and at what ipw?

 

okay so I gave my MBC another 1/4 turn to increase the boost a little.

3rd gear pull on the on ramp I maintained a 10.5 AFR up to 5406 RPMs then I let off because of traffic

I hit a peak of 993.82 Hz @ 5312 RPM

0 counts of knock, but during the pull SES light came on and it was cylinder 4 misfire???

Anyone notice that 3rd gear is richer than 2nd?

 

Btw my IPW peaked at 19.2 @ 5093 and tapered down to 18.688 @ 5406

I'm gonna turn up the boost by another 1/4 turn and see if that leans it out a little. 10.5 AFR at 3rd gear is too rich for me
