All factory functions have been retained to include ABS, ESP, Cruise Control and butter smooth Idle. A MAF is also utilized as well as N75 controlled boost to provide OEM like driveability. It is like driving a bone stock car until you mash the gas pedal to the floor. It then takes off like a bat-out-of hell. Idle, Part throttle and right off-idle is spot on and driving in traffic is very controllable. I drove to work today and barely boosted over 10psi yet the car still got out of its own way. Driving home from ASP averaging 80mph with a few spirited pulls at WOT I still got 28mpg! This is the way it should be. This is what I have been striving for in my car's build.
The 'base file' is also now available to the general public for those with a 30 series or equivalent hardware configuration. You can contact ASP for more information.
Below are the details of my car.
Engine Specs:
2008cc stroker bottom end with forged CP pistons (9.0:1 CR), Scat connecting rods and factory AEG crankshaft
big port AEB cylinder head with 1mm oversized Ferrea intake and exhaust valves, Rosten valve springs and Cat Cams 3651 camshafts
Garrett GT3076 turbocharger (T3 turbine flange, 0.63 turbine A/R)
TiAL 38mm wastegate
Fueling:
Bosch 040 in-tank fuel pump
Seimens 875cc/min (rated @ 3Bar) fuel injectors
stock B6 A4 returnless fuel rail
stock B6 A4 fuel lines
stock B6 A4 fuel filter
Software:
Autospeed Performance Motronic tuning consisting of N75 controlled boost utilizing a MAF
Other:
3inch cat-less downpipe mated to an APR stealth cat-back exhaust
custom 3" thick FMIC with 2.5inch hot side piping and 3inch cold side piping
custom TIP utilizing an ASP oversized MAF housing and MAF sensor
INA intake manifold with 75mm throttle body
'base file' - "pump gas"
93octane (no water/meth)
22psi boost
96*F ambient
N75 controlled boost
stock AEB intake manifold and throttle body
(also my winter file for driving in the snow and horrible New England roads)
high boost "pump gas"
93octane (no water/meth)
28psi spike tapering to 26psi
96*F ambient
N75 controlled boost
INA intake manifold and 75mm throttle body
This is a first pass at tweaking the 'base file' to run more boost and make more power. Timing advance is conservative and was limited by the hot ambient conditions and the 93octane fuel. Boost is currently set to taper as we were keeping the file somewhat conservative for the hot ambient conditions. More to come on this file in the upcoming months.
The other cool feature I picked up is the new SpeedPort iPhone application by ASP. Details here: http://www.speedport.us/speedportapp.html
Using my iPhone, I can switch between the files loaded on my ECu as well as Valet and Anti-Theft. All done wirelessly. I can also monitor channels within the engine controller (timing advance, boost, RPM, fuel trims, etc..) and data log those channels while saving the data log to a CSV file. I can also clear DTCs within the engine controller should one pop up. Of all the mods in my car I think this is one of the coolest mods. I need to get a video of that in operation. I should have some time next week.
EDIT (July 13th):
Tried some videos but there was a camera fail. Next time.
