God please tune my Sleeper Audi
Whats up peeps! Can anyone help me out?? Information maybe pointers, anything..
I broke down and bought the 2.2L Eurospec motor.. all the fancy forged out high performance parts.. I mated a garrett gt3071r turbo to the beasty motor, threw on some 60lb injectors and shipped my ecu off to unitronics to be tuned.. We'll I have a few Major problems..
1) On a perfect winter day it will take about 15 - 20 turns of the key to start. *once started, don't touch the accel pedal or it will choke out*
2) The boost come on in stages.. 5psi right off til about 3200 and it bumps up to 11 psi, then once the rpms hit 3800 i'm at 16psi and flat out booking it down the road.. I believe it should be a steady increase in boost, not staged out.. right?
3) The car ran fine for a while and now it seems that its running lean.. or trying to be anorexic.. I give the accelerator pedal normal pressure from my lead foot and once the turbo kicks in its like all the gas decides not to flow and the wastegate releases, then tries to hold again, then releases, then tries to hold again.. im not getting enough petro to the motor..
4) What is the best way to log the ECU so I can ship the data to unitronics and have them update the file.. Someone else has to have mated a 2.2L eurospec motor with a gt3071r and 60lb injectors.. right?

Yeah, 2.2L is the biggest stroker motor you can do

Thanks blackwat5r! I bought the car with an upgraded fuel pump, unless the dude totally scammed me.. it had the 1.8t with a k04 and exhaust.. I HATE THE EXHAUST TIPS.. sorry had to vent.. Oh please don't make me change my fuel pump haha I'm gonna get a fuel psi gauge and see how much pressure I'm really getting. I appreciate the input!
Do you know if resetting the engine error codes could mess with the tuning? If so I know a possible problem lol

Clearing the codes will not affect the tune.
Yeah it's very unlikely that he upgraded the fuel pump with a k04 seeing as how its unnecessary

..oh how I don't want to change the fuel pump, but it does make sense. I am callin up unitronics to see about having the ecu tuned again. If that doesn't fix it, I'm gonna pop in the new pump, do some data logging and retune it again. I can't wait to have this thing running right.. Thanks for the help!!
