hmmmm 8hp up? i dont think so coz by theorically grounding just makes the current flow perfect, now are days our cars grounding is considered efficient.Originally posted by Yong_5290@Feb 15 2005, 02:41
8 hp up wit juz a grounding???
hmmmm modern cars do have sufficent grounding but sometimes not all production are perfect, u know wat i mean. for engine bay must be sufficent ground. Caburator and Injection earthing theory is almost the same, Why must have sufficent ground? the alternator must be grounded properly inorder to eliminate signal ground distortion, secondly engine is ground due to spark combustion is very depend on grounding nomatter injection or carb. For injection, it need to have at lease 13v to run the injector properly, normally for ie: wira 1.6 manual, injector voltage is 2.8mv when idle and 3.8mv +-5% when reving at 3500rpm. if ur car idling at 12.5v below then ur injector will be 3.2mv due to voltage lack so ur car will consume more petrol at idling.Originally posted by stroker_kit@Feb 15 2005, 16:42
but datsun 120Y dont have ECU, so no point also....good grounding are to make sure signals from various sensors are as clean as possible, so that the ECU can work and calculate correctly... bad signals will give wrong info to ECU, thus resulting in power loss on improperly grounded cars.... yes, modern cars may have sufficient grounding, but r u sure its good enuf??
however, different car has different behavior...so the hp increase figure may varies... but at least, u can be rest assured that ur groundings are good ...
lastly, that APexi product above is not just for groundings...its a voltage stabalizer which has similar functions.... to have clean signals...cleaner than just having a good grounding....
take it this way...why not take out the O2 sensor entirely....although ur car can still run, im sure it'll produce less power than normal... this is to prove how "bad/false signals" can affect ur engine performance...
