Just want to check something with the rest of the UDM drivers.
I've got a 330ci with stock exhaust, superchip and sprint throttle. I want to know if the characteristics of the throttle is common or just my car.
Anyway lets say i am cruising at 10% throttle @ 3k rev and I increase the throttle to about 15%. I notice that instead of the rev increasing from 3k rev, but it actually decreases about 500revs. (btw, % of throttle is not accurate)
Also, i was in KL and balancing the car for a short while without pressing the the brake but with the throttle. After that, I experience that the car will jerk whenever i press the throttle to accelerate. Its asthough the car got problems with fueling. Too rich or lean. I need to drive a bit, than only the car will improve slowly. The jerk is like a sudden cut in the fuel, like a fuel cut or ignition cut feeling. Very scary.
Finally is the acceleration. I find that my car got problems thinking which gear to change to. I realize that for a 3litre, the car is quite underpowerd. I need to press quite a significant amount of the car to either change gear, especially at around 80km/h. Is this because of the superchip or the sprint throttle that confuses the ecu.
Sorry for the long winded-ness. Just very curious and afraid its a problem than needs to be rectified. Also I havent done a sensor scan but will do it tmr. All opinions will be appreciated.
Thankssss
