I'm in the process of connecting a DTA S80 ECU to by S4 engine (BBK). I need to know how the cylinders are numbered and what the firing order is.

Any help appreciated.

Not sure if you are still seeking this information ... for BBk engine, firing sequence is 1-5-4-8-6-3-7-2

Not sure of cylinder numbering sequence though .. will have a rummage to see what I can find.

It seems 1 is front left cylinder (when facing engine from front of vehicle), running back to cylinder 4 at bulkhead end.
Cylinder 5 is on right nearest front bumper, running back to 8 at bulkhead.
