well the shop that did mu pipes blew it on the y pipe. The intake to it is in at an angle so its clearly not splitting evenly. Thinking about it now I think it's doing what it was when the kits was first installed. The shop that installed it left off the part that blocks the lower filter so when I would coast at 3-40mph one MAF was getting more air that the other and the car would go into some protective mode and go pig rich. Our thought right now is that while we are not trying to tune it with the MAFs the car is still going into that mode because of what it's seeing from the MAFs. First we are going to try to trick the car, we are going to attach both MAF signal wires to one MAF so they get the same reading and then see if we can get anything to change SD tuning it. If that doesn't work we will have to have a new y pipe made.

Man! What a search for a problem! ! Awesome build!! Hope you fix that's and hit some major big numbers!! So frigging cool.

If you end up on the 'rebuild' path I would give them direction to have at least a small straight portion before the 'y'. It will also help to have that flow conditioner inserted too.

Sadly I had asked the shop that made this pipe to do both of those things. If we rebuild it I think we are going to do it like Evohunters, it's simpler takes up less space and with the MAFs in the same pipe they should get the same readings. Yes it will run out of MAF but I already have the 3 bar MAP for SD tuning so that shouldn't matter.

Interested to see how that works with SD tuning if you are out of MAF.

Props for being a pioneer :tup:

Yeah SD tuning is the way to go for sure. I know our MAFs are now in different locations with the air to air but I was able to take the box from around my intakes out that blocked the air and wind coming in and as much air can hit the MAFs and not have any effect on my tune. Doesn't matter what they read. SD is straight from the manifold pressure. Will definitely solve your issue.

Hmmm... then this isn't going to work, we have been trying to SD it and the car just keeps going crazy rich. We were thinking the ECU is still seeing the MAFs and going into the protective mode and going rich. The car will idle in the 13-14 AFR range for just a bit then suddenly it goes rich.

I know that Ecutek has an option with speed density that you can use either hybrid mode where it looks at both the MAP and MAF sensors which is sometimes used to get better readings at idle and low speeds or just straight up through the MAP. You might check to make sure it is only reading the Manifold pressure and air temperature readings.

Hey Guys

On March 2016, i can, or will Report about "SD with EcuTek- Tuning"!
That's our future-plan.....:tup:

Topgunz car is running on it now with out any problems but something on my car just isn't letting us tune it either way.

The ECU must still be doing something off the MAFs because the car will not run with both plugged into the side that is .8 but will idle (not well) on the 1.6 side on the same tune.

I just got this message, there may be hope still!

Good news!

I'm a little to nervous to get to excited but it's the first time the car has let us actually change how it runs with any of the 20 maps so I'm hopeful.
