Need guidance on setup
Guys, could really use some help here as I'm quite a newbie to the B48.
I recently took ownership of a G20 320i (2.0litre B48 engine). It came with a M Performance exhaust, drop in filter (brand unsure) and a 200 CELL downpipe, running BM3. It also has a DTE Pedalbox which for reasons I will explain later, I set at Sports (-3) setting. The problem I am facing is that the drivability at low speeds is almost impossible. I could just breathe on the accelerator pedal and the car jumps forward, making traffic jam style traffic almost unbearable. It's like wayyy too responsive. Deceleration at low speeds is also unbearably jerky. The DTE at Sports(-3) seems to help a bit - Havent tried City mode though. My questions: 1. I have a VSRF catless downpipe waiting to be installed. Will this help to reduce the backpressure? 2. Will a MST open-pod air filter make any difference? 3. Should i just remove the DTE pedalbox altogether and trust the hardware setup? Any advise will be appreciated. Thank you so much. |

If I were you, I'd remove the pedal box and see how the car behaves after. A tune and the other hardware mods shouldn't make your throttle that twitchy.

Probably the pedal box.
the intake will get the car to sound better and maybe add a few HP, wont make any difference in throttle sensitivity

I like the sound but I would never spend 1000s of USDs on one. It depends on your choice and how much you're willing to spend for the extra sound.

No drowning out because the IAT is too high after a long drive. In this sense, it is no doubt giving you the illusion your car is faster. That being said, with a tune and a CAI, the car can be considerably faster, considering the intake piping diameter is bigger than stock, there is definitely more volume of air getting to the engine at once as compared to stock. All depends. On stock tune, I doubt a CAI would make much a difference besides in sound. |

Get rid of the pedal box. This type of device is used on economy cars with electric throttle actuators to make them feel like they have more low speed power. It is not needed in a BMW.
The box just changes the throttle actuation so it is no longer linear and matched to the pedal position. You move the pedal a little and it moves the throttle on the engine a lot more. In its worst setting the pedal becomes almost an on/off switch as you press down. |
