Thread: MAF Issues?

First off, here is my setup:
B14
sr20ve
GTIR T28
STI 520cc Injectors
N62 MAF
CalumRT

I have been driving the car for about a month with an N60 MAF and it has been drivable (pretty rich if I went WOT, but i tried to avoid doing that since it's not tuned). Since I was having trouble getting a base tune for the setup above, I swapped out the N60 for an N62. I got a base tune file for the setup above, except it was for a DET, not a VE-T. I figured It should run at least somewhat decent if not fairly well with that being the only difference. Boy was I wrong. I uploaded the new tune after swapping to the N62 and this is what I get...

Does anyone have any ideas?

I swapped the N60 back in and it is running the same as before.
Here is a Log of a 2nd to 3rd run. I don't know why the AFR is low, it was showing no less than 10.5 and no more than ~14-15 on the gauge or the laptop during the run.

what consult is that, looks pretty user friendly. I have a great .bin for b14sr20de, 520, 3 bar, n62 maf that I got from likethemovies. All you should have to do is change the timing maps over to ve maps if i'm not mistaken. The whole ve thing is greek to me. I have a u13 det and changing the maps is pretty easy. If you can't get a hold of me check with him he's getting pretty good with this tuning ****.

It's nistune. Hmmm, that's where I got this one... Could the MAF be bad? What is the best way to check?

Although, I didn't change anything on it, so do you think the timing maps could make it do that? If so, can I use a timing map from an NA VE base tune? Or is timing different for boosted cars? I could try pulling the timing map from the N60 BIN too i guess. I have never done that before, can I just copy/paste it some how?

Bump, trying to figure this out before Saturday, I was going to try to make it to a dyno meet!

do you have a VE bin? If you have a VE bin email it to me and i'll change over your timing maps for you. In your original post you said you had a n62 maf not an n60, which is it? And you are running 3 bar fuel pressure correct?

I have a VE BIN. I have the N60 on there now, but I have an N62 I was trying to get to work. Yes, I am running 3 BAR.

change your vq maps to an n62 maf
