Yup those are the ones

 

thanks, i should get them this week. the guy is in socal.
hopefully they'll work fine without problems, if not i'll get them cleaned and flow tested

 

looks like my old ones. They work very well!

 

I was just thinking about this a few days ago and came to the same conclusion ... the MAF Scaling table. I didn't consider it at first as the MAF should be calibrated correctly in most cases. However, in the case of a boosted Lancer, the MAF is calibrated for airflow correctly, but it doesn't take the compression of the intake charge in to account.

In short, the MAF is reading the air correctly, but we're shoving more in to the engine since it's now compressed. Because of this we need to compensate and recalibrate the MAF. I'm glad you all were able to come up with this solution ...

 

Exactly what i stated in the early post Man i wish you lived over here in TX i want a tune bad.

 

Guys, I'm currently working on 2 cars that I'll be trying this out on ... I'll let you know how it works.

 

Great keep us updated!

I'm still curious on what the MAF Smoothing Table does

 

Given the name of the table and the curve of the values, I'd assume it's purpose is to decrease fluctuation in the values in the low HZ range. A filter for the low flow values if you will. I've never used it though so I don't know this for a fact.

 

So the MAF smoothing would be more for regular driving and have less effects on WOT.

I got my injectors today and I'm sending them out to RC Engineering for cleaning, calibration, and flow testing. Turn around time is 24 hrs so I should be able to install them this weekend. Time to scale injectors again! =\

 

^ prolly could help with partial throttle conditions like when you run the revs up high but still only easy on the throttle... We could prolly lower the value a bit to trick the ecu into thinking theres more air right? to solve the problem with the ecu dumping fuel cuz were in the higher rpms but turbo isnt spooling yet?

 

the smoothing tables shouldn't affect fuel delivery that much at throttle. A MAF system is pretty smart as it knows exactly how much air is in entering the system. If you have part throttle issues you should be able to adjust MAF scaling in that hz range to tune it out. Your STFTs (O2 Feedback Trim) will give you that info.

Once big issue however is improperly set up injectors ... if you latency values are incorrect it can really screw up your part throttle trims.

 

Which way would i adjust the maf values for certain stft and ltft conditions?

 

If STFT is + you increase the MAF value. You have to keep airflow steady for a few seconds for accurate readings though. For LTFT, the low trim reflects values under 100hz and mid trim is 100hz to 500 hz.

+ means the ECU is adding fuel and increasing the MAF value lets the ECU know that there is more air than it's expecting.

If you're going lean at WOT, increase the MAF values in that hz range.

Divide the left column in the MAF scaling table by 10 to get the hz value. The last cell, 16XXX is 1600 hz.

 

Thank you Touring, you always have some useful information.

 

Jurt the answer i was looking for. Thanks a bunch. I.ll be mdsring with thd settings this weekend.
