A16LEL Rough Cold Start

[Heli1922]

Cześć! Przepraszam za mój język, ale jestem z Polski i nie mówię dobrze po niemiecku.

I'm A owner Corsa D A16LEL with few mods:
- wydech prosty z vkerem 3"
- większy intercooler
- Wtryski Bosch 395cc
- suchy filtr pipercross
- niestandardowe przemapowanie etapu 1.

Half year ago when weather is cold I noticed my car need a longer time to startup (maybe 1 second more). One Time my car starting and after moment turn off. Second try is good and corsa start well. Month ago I'm noticed little bangs when car is starting but idle is good, no misfires. 3 weeks ago i'm going to our local garage because my remap is bad(im saw A overboost to 1.7 bar) so i upload stock 150HP software with calibrated bigger injectors to my car. Next day when i'm trying to start my car in cold engine im getting rough idles, car misfiring, rpms going Down to 500, after moment up to 1600 and down to 1200, Then everything is okay. I dont get any misfires when driving on cold engine. Anyone have that issue? Now im have better stage 1 remap with 1.35 bar boost, and car drive very well, have A lot of Power but cold start is very bad. Plugs and coil pack have A less than year, coolant temperature sensor 2 years. In photos i'm show you my cold start parameters.

jakie było rozwiązanie

Czujnik mapy. Moja temperatura powietrza wlotowego wynosi 40 stopni w zimny poranek, kiedy od tygodnia nie jeżdżę samochodem. After replace it's looks like ambient temperature, so that's help.
