REVIEW: Don't bother installing voltage stabilizer?- with pics and comments

[yfin]

I was supposed to help my friend do it but he started before I arrived, at the very same time and saw him meddling his wires in the engine bay, I saw fireworks coming out of the engine bay.....

Don't forget to D/C the battery before you wire them up!

haha - even the Pivot instructions as bad as they are make that clear!

Installed the Pivot Voltage Stabiliser today. Pics below. We ended up using all the wires provided by Pivot (connecting to body earth, near cylinder head, the ecu sensor under the intake manifold cover, the alternator and transmission case).

Now my rudimentary understanding of the Pivot is that it stabilises voltage fluctuations. Is this supposed to happen when the car is running or only when starting? Does anyone know. Because read on. I took some readings of the voltage before and after installing the kit (using a feature of the Apexi RSM). In both cases the car was warm and at idle (around 650rpm with no accelerator applied). The readings were taken one day apart.

BEFORE
Base line no accessories on = 13.9 or 14.0
AFTER
Base line no accessories on = 13.9 or 14.0

BEFORE
High beam flash and hold high beam voltage reading = drop to 13.4 then stabilises at 13.9
AFTER
NO CHANGE

BEFORE
Air con turn on = drop to 13.1/13.2 then stabilises to 13.7/13.8
AFTER
NO CHANGE

BEFORE
Headlights on = drop to 13.7 then stabilises to 13.9
AFTER
NO CHANGE

BEFORE
Headlights and fog lights on = drop to 13.7 then stabilises to 13.8
AFTER
NO CHANGE

BEFORE
Headlights and fog lights and high beam = drop to 13.7 then stabilises to 13.8
AFTER
NO CHANGE

BEFORE
Headlights, fogs, air con drop to 12.7/12.8 then stabilises to 12.5 or 12.6
AFTER
NO CHANGE

Result: I see no "voltage stabilisation" when accessories are turned on or off. Just in case someone asks - yes I have the genuine Pivot model (as verified from the Pivot website as to the markings only seen on the genuine model). And as to whether or not I installed it correctly I had it installed by a motor mechanic (aka my dad!). Pivot blue light is on and working. Can someone explain why this product doesn't stabilise voltage or is this just a marketing ploy?

This started off in the Euro forum - but it has turned more into a review of this product generally so I have moved it. Interested in comments please.
