firing order

Hi,

as I am abroad and do not have access to WIS, can anyone reliably tell me the firing order of the M177 and M178.(should be the same)

Google is contradictory

Thanks

Best regards

Another side effect of the move to a flat-plane crankshaft is a new firing order. The 4.0-litre V8 now jumps between cylinder banks, with a 1-8-2-7-4-5-3-6 firing order. This creates uniformly oscillating gas columns which generate a predictable flow of gases through to the turbochargers.

Hi 57 GTR,

thanks, but this is for M178 LS2 with flatplane crank. (e.g. Black Series)

Need the firing order for M178 LS 1 with cross plane crank.

Best regards

This firing order is 1-8-4-3-6- 5-7-2. Just as with the LS1 example above,

Hi 57 GTR,


Thanks, but are you sure? Where did you get the information from?


1-8-4-3- !!!6-5-7!!!-2


Here, 3 cylinders would fire one after the other on the left (direction of travel) cylinder bank.


Is this firing order, with this cylinder counting?

Transmission

4 O O 8
3 O O 7
2 O O 6
1 O O 5

Front of car




Best regards

Stenzel
