Promise to give Eric a review on his VS. There are couple of things that improve my ride after using Eric vs.

1. one crank able to start the car
2. no rough idling
3. changing gear become even more smooth
4. engine become more quiet while cruising 80km/h
5. vtec feel more kick while engage
6. aircond more cool than usual. Turn my aircond to max, u wont feel the air cond compressor drawing all the power from the alternator. Mean no sudden rpm drop.

Well, i am driving honda prelude 92-96. Almost a 20 years old car. So this vs really help a lot and out perform my other vs which made in japan and had been using it for 7 years. So any1 of u who still have any doubt on Eric vs, i personally guarantee u that his vs really work. The bad part is my car lack of space, else i will get another unit from Eric

As far as i know, making the cable longer may effect the charging and discharge effect. Seriously my engine bay no space:) I will send u my engine bay pic tonight after work, see can fit another vs or not:)
