[Motor] Changing Injector Size

faye116
Hi all,
有人改過嗎?
目前看到Bosch有出24lb的injector...還有30lb..42lb..
JRSC是用到30lb的injector...

磅數到底代表了什麼?...我換高磅數就會比較耗油嗎?...
另外還要加上高流量汽油幫浦嗎?

目前已上SCT...裡面有幾個調整選項想自行玩玩看...
Fuel adjustment...
Fuel injector size selection...

Switch to high flow fuel injector......
Max. horse power output -> Maximum Duty -> Fuel pump specification
-The proper injector size could be calculated

-130hp NA engine, ~20 lb/hr
-150hp NA engine, 23~24lb/hr

Minmum controllable duty VS. Close loop stability
-If the injector flow is too high for the engine, minimum duty would be hard to controlled well by the O.E. ECU setting and might lead to idle speed fluctuation or instability. When the injector worked at lower duty, the slight change of duty cycle may not response as smooth as proper designed system if the ECU or other hardware keep unchanged.
