I was thinking to zero it out and add timing and if I subsequently get knock then to remove it from TCPC A+B first?
Somewhere I read it
could be because of where the knock sensors are placed and to ensure that C+D knocks first so the sensors can actually pick it up. I doubt that is the case since the sensors are located between the cylinders each side on the FA20.
Besides, the tables are already zeroed out up to 6000 rpm anyway.
A is probably cylinder 1 according to RomRaider. B is 2 or 3? If 2, those would both be the best cooled cylinders facing the front of the engine? If 3, could the right side run hotter maybe (exhaust cat below)?
Could it rather be because of flow in the stock header? In which case, the compensations may not make any sense with an aftermarket header? Are there any changes to these tables in the MY17 with the revised header/intake?
