I think you need to add some engine ground and voltage stab... on it... mine i added engine ground ord but haven add the voltage stab yet. it don have the feel unless you on the car light.. mostly happen when nigh time..

have you try to ground one cable to your fuse box there.. mine still waiting for the VS to be arrive cz of my old one sell together with my old kelisa. btw the pivot blue and purple is here any power different between?

What i mean is put one of the grounding cable near the fuse box area.. so maybe the cable will help return the grounding more faster, if not mistaken there is one original cable connected over there but the cable is very small, if not mistaken last time my kelisa also face this problem after a accident my friend help me to ground a cable to the alternator then the no more very serious dimming and engine vibration

mine is 2.7% RHB 2013

9 years.. and i have 1280 discount and 3 year free service.. and i heard that the 3 year free service no more ord..

lucky is lucky but i have wait my car for about 1 month for it to arrive... at the same time i have sell off my kelisa... one month no car to use lol...

ya its true.. coz my car arrive my place 3 days before the 3 years free service launch, my saleman called ask me that do i wan to wan until it launch just register the car so that i have 3 years free service. since i have wait for it almost 1 month so why no.. lol.. and now i leave 2 more time free service..

i would ask you remember check is there a spare tire there cz my friend collect his car without check it up not long ago he just notice that his viva came without a spare tire..

mine added UR bar for engine side only and have change my tires to Pirelli CINTURATO P1 so far so good... and also changed my break pad to bendix

for toyo t1r i really don know
sorry i forget to give you the size i am using, ya i am using 195/55/15 it was way better than orginal silverstone 185/55/15 and lucky i have change it early before the tires broken, cz of one of my friend tires crack from the inside two month later i have changed my tires.

mine 2 years finish, for me i will advice not to use bendix maybe it was too hard, some how it make very sharp noise when braking and i have clean the brake pad once ord after around 2 month the sound back again. i was thinking to change to brembo but i have out of some budget so put it on waiting list and also the denso park plug... hehe...

mine have 2 layer sound proof on 4 door but the wind sound came in from the window side..
fully speaker changed to infinity component set also with a pioneer woofer power up with coucar 5 channel amp,
head unit pioneer double din

i choose for bendix is cos of my friend i asked he help me to change the pad he tough i am in a rush so he took his ready stock for me to use... so didn manage to help me order the brembo brake pad...

ic but my car audio setting is more to SQ.. not really like SQL hehe...

ok thanks for the advice... will consider it...^^

i would recommend not to use synergy M5 coz the internal will be cracking and peel off this happen to one of my office uncle's car...

alza can use it??? i tought alza cannot use this cz i try last time using my friend one cannot use o..

can you give me more information on the remapping you mention. interest on it..
