Had this exact issue when I installed my Eventuri intakes a while back. Just had to tighten down one of the clamps on the silicone couplers.

Reading this forum I read that the problem may be EVENTURI intake. That's why I checked all connections very carefully. Despite this, the problem is still there After uploading the MHD program, the problem subsided for one day, but after driving a few kilometers and the next day firing again, the speed jumps.I upload the STOCK maps again and the car starts normally, when I drive the car again the next day when firing, the revolutions go crazy. I upload the mhd map again, e.g. STAGE 1 STAGE 2 STOCK, this car can stand in the garage for a few days and each time after starting the engine the speed is good. just drive a few kilometers and the problem returns
after each FLASH the car fires up and works normally until you drive a few kilometers and the problem returns ..... Last edited by motosportm4; 12-01-2019 at 02:01 PM.. |

Check your mass air flow sensors. Make sure there is no damage and installed proper direction of air flow.

Have you followed the advice thus far? A fresh flash takes all of the learning away. Likely a leak after the MAF that the ECU cant compensate for. Reinstall OEM intakes or at least check MAF sensors in the Eventuri setup. A good shop can read MAF signals, maybe a sensor or wiring was damaged?

the car was at several BMW mechanics. Replaced: valvetronic engine, candles, injection. Still the fault and problems is with the morning start only stopped clicking after waking the car as the valvetronic engine was replaced. But the problems with starting the car are still there and these errors are sent which I send after replacing the vvt engine. I am looking for help here because in my country nobody knows what is happening with this stupid M4!
