Message: <blockquote data-quote="levin818" data-source="post: 366841" data-attributes="member: 849">Actually, we don't need 82,000uf if it is only for your ECU and sensors, a few thousand uF is more than enough. A stock ECU only have 47uF x 2pcs in the circuit. And if we take a look on the Jpn made VS, it only c/w 4pcs of low ESR high performance E-Cap + 1pc of Ceremic Cap. Judging from the E-Cap size, it should not be more than 4700uF 50V. However if we have ICE system, then 82,000uF will be able to enhance the bass SQ.Again, i would like to stress that 16V E-Cap has too little voltage margine against 14.4V. It must be at least double or triple for safety measure. If those 16V E-Cap blown off due to surge/spike voltage from alternator over a period of time, the result will be like short circuit the battery terminals. And if the fuse cannot react fast enough to cut the high current, this high surge current will create a huge disturbance in the supply line and might kill the ECU! This is why when we mistakenly short circuit the car battery, beside getting smokes and fires, sometimes we have to pay for the ECU as well.It is good that if we can make and sell our product. But please bare in mind that once we make this first step, we have to responsible for our product reliability.</blockquote>
