MAF Tuning Help Needed

I'm trying to dial in my MAF, but I'm getting something like this on my LTFT's. I've already raised the lower end up to 8999 Hz by 20%. I think the lower range needs to come up more, but I'm not 100% sure what to do with the mid/upper regions.

I did a little bit of tweaking, but I'm not getting much closer to 0. I've scaled back 2% twice, now, but my numbers haven't changed much from the two previous scans.

If you are dialing in your maf why are you using a VE histogram?

Right. The MAF table is a linear table. So In other words it looks exactly like the maf table in the editor does. You can tune trims like this also (by using the VE table) but it's a mater of opinion really. I have always used the MAF to tune fuel and trims.


You have to setup up a custom histrogram. I'm guessing he is doing this for you. So let us know how it goes.

Yes I'm gunna set him up with the correct config file for this. I also like to look at people tunes when I help so I can give them advice if needed.
