alright I moved cylinder 2 injector to 1 and 3 to 4... before i was only seeing misfires at idle on cylinders 2 & 3, once i moved the injectors the misfires moved with them. their were no misfires on 2 & 3 but misfires on 1 & 4.... so I think it is safe to say that the injectors are bad....

 

get some genesis injectors, far better.

 

okay I went and logged the car, and this is what I found: The ecu requests a lambda value of .90 (13.2:1)till about 4500RPM's then the lambda goes down from their and requests .82(12:1) at about 6000RPM's this still seems lean to me... but what do I know?

I tried to take it to redline but I such at shifting, and the rpm's come faster than normal (I went from stock to BT ) I am going to get new injectors but I think the AFR seems to be "slow"... should it be like this or should it be different?

 

I see now.

The larger housing is lettingair go by the sensor unmetered; thereby, givinglow readings at the MAF sensor. Unitronicsthen adjusts their fuel maps toaccount for this unmetered air.

 

Unitronics usually tunes forafuel pressure of4 bar. You may want to contact them and make sure it's set correctly.

 

God, I love it when people figure this crap out. Where you on stock injectors?

 

he had 440 green tops, you not read the thread?

You can increase fueling via lemingwinks,with the fuel tweek. Also uni has a new setup like limingwinks that can be downloaded in the 1.8t section on vortex to do the same thing.
