sent the log!

 

[HolyCrapItsFast]

Okay looking now

 

[HerThing]

Oh, i will add, that was the best it has felt under boost in a long time. Not sure why all of the sudden its wanting to play nice and i haven't changed anything...

 

[HolyCrapItsFast]

It definitely looks like you have a leak. In the email you sent me you say the AFR gauge went to 12.6. Was that when you went WOT? Did it ever go richer than that?

 

[HerThing]

nope 12.6 was bottom.

 

[HolyCrapItsFast]

Okay I think you have a leak after the MAF sensor and before the turbo.

You may need to perform a boost leak test. Look for leaks where the turbo inlet couples with the turbo and also look for leaks around the MAF sensor itself.

If worse comes to worse I can make you a map that will compensate for this issue but it will only be a bandaid.

 

[HolyCrapItsFast]

honestly though the smoke test should have showed something

 

[HerThing]

Thats what gets me. the smoke test shows nothing. I cannot find a damn leak. all the hoses are connected, short of completely pulling and installing the inlet all over again. its been on there for over a year and just now issues.

 

[HolyCrapItsFast]

There is an average +15% error overall...

 

[HerThing]

well, i hope there isnt a hole in the tube. could it be a maf issue, or absolutely not.

Was the original tune on this intake?

This intake is actually smaller than the stock unit so the fuel trims should be negative, not posItive and certainly not 15-25%

 

[HerThing]

well, its actually set for the kstech intake, ron noticed that last night. but when he changed the maf scaling for this intake, it wouldnt run at all.

 

[HolyCrapItsFast]

Your using the KStech intake right now?

 

[HerThing]

no i am currently not. it was rubbing on the inner fender, starting to wear through, couple that with the filter on it was hit with a rock. its pretty much trash.

 

[HerThing]

and the maf doesnt seat correctly in it.

 

[HolyCrapItsFast]

What exactly is set for the KStech. If you are using the Stage 2 OTS map then it should be using stock MAF scaling. In that case the fuel trims should be rich if the injen intake truly is 2.5 inches. In this case there is a leak.

Let me ask you a stupid question. Are these stock injectors?

 

[HerThing]

yes to stock injectors. its a 2.5" intake. i have measured it. I also ordered a 2.5" filter for it from injen.

 

[HerThing]

oh, and sorry, the scaling was different on his tune, not the accessport.

 

[HolyCrapItsFast]

Okay then I feel you have some troubleshooting to do

Let me know if you need a bandaid map to drive around on for the time being just to keep things safe

 

[HerThing]

oh, you might find this interesting. ever since i have had the car, if i fuel up with it off, it runs rich and develops a misfire, unless i shut it off and start it back up.
