RSI said:That is caused by detonation. Can happen when driver was blasting with low fuel causing a lean condition. Detonation then blew the gasket. Water goes into the engine. Then hydrolocked the engine.

hattech-v said:after the blown engine replaced with b16a, then the owner went to dyno it using the same ecu (mugen chip) n the afr reading is very good (12.8) consistent from 3k-8k rpm.
lets say if he use this ecu on b18cr, will it make a big different on the afr?
hattech-v said:closed loop for cruising n open loop is for WOT if not mistaken...
closed loop get the value using the sensors while open loop get the value from map table... or the other way round... hehe
shiroitenshi said:You're right.. I don't usually remember this, so I looked up google in case.
Yeah.. closed loop means that it gets sensor readings, apply fuel.
open loop means that lookup table + 02 sensor = fuel + fuel corrections, apply fuel.
Still, how much psi did you guys run the fuel pressure regulator, when the mugen ECU on the B18CR?
hattech-v said:standard psi using standard non-type r fpr... not adjustable one.
shiroitenshi said:Wah.. and you actually use the ECU on the B18CR? Shouldn't have that resulted in random detonations?
If I'm not wrong, the type R fuel tank pump and the type R fpr results in a higher pressure than the stock B16A, that's why they can use same cc injectors, in conjuntion with slightly tweaked fuel/igniton maps for the 1.8block.
Well.. RSI might just be right with his theory then.
