Hej har nu bytt till nya insugningspackningar m.m till min 850 csi, vilket ju betyder att jag monterat bort t.ex spjällhus etc. Bilen är nu klar att startas för första gången, är det något man bör tänka på, har läst en del om synkroni-sering av spjällhusen men vet ej hur detta går till ! Tacksam för tips ! Allt är rengjort och fint, har också bytt bränsleslangar etc. etc. Mvh Pär | |

Hej! läs nedan, lycka till. Resync DK Motors Throttle Bodies From the BMW 850 repair manual: 1. Run engine to operating temperature 2. In 1st gear run the engine up to 5000 rpm and then let it coast down (still in 1st) down to idle and let it idle for 10 seconds 3. Do Step 2 two more times for a total of three times 4. Place the car in neutral or park 5. Idle for at least 5 minutes 6. Shut the engine off for 10 seconds 7. Restart the engine Result: Both DK Motors should now be synchronized and the adaptive system engaged NOTE: Also per the BMW 850 repair manual if the EML control unit were without power for a long period of time (e.g. more than 1 hour), its adaptive system would lose the stored values. The adaptive system needs to read in and store the input values of the engine after restoring operation of cleared-out EML control unit. The coast down procedure described above would fix this. Additional Information: On the V12 versions of the 8, there are two throttle body motors that open the butterfly valves on your intake manifolds. They are the two items sitting at the top front of your motor that look like little electric motors. In order to insure proper air supply to both sides of the engine, the butterfly-valve motors need to be synchronized to insure balanced power from each of the banks of 6 cylinders. In essence it is like insuring that both legs are of the same length for you or me. The synchronization process adapts and changes the settings to insure balanced airflow thought the butterfly valves by reinitializing the computer feed to the motors. The 8 series actually employs adaptive computer control each time you drive the car. If you drive aggressively, the car is more responsive but less fuel efficient, if you drive more conservatively, the car will adapt and will be less responsive to throttle input (and other factors) but also will be more efficient in fuel use. The system was very advanced when it was released in the early '90's. The old problems with V12 motors from makers such as Ferrari were balancing power output from both banks of cylinders and that required a lot of (spelled frequent) tuning. The DK sync is BMW's answer to those types of problems. |

Tack för snabbt svar ! Menar man att man ska köra på 1:ans växel på väg som det är beskrivet eller går det bra att stå still och varva med 1:an i och kopplingen nere ? |
|
| Ja man kan ju göra det på "bänk", upphissad eller på väg. | |
