Mivec 4g63 Vr4/1G Kiggly Racing

From my experience, changing dwell time for cdi setup does not have any effect... maybe my car not properly setup that why it different from kiggly's car that "need" 7ms dwell time.

adoiiiiiiiii , dont la give wrong spec, hehe then everyone silap
kiggly is not running 7ms , he is not even running sequential firing
he is running on batch firing with dynatec arc CDI , with CDI where laaaaa got 7msss dwell baiiii

AMS and BR are using non ingitors buildin , 300m coils , one of the biggest player on the market would be Sparktech

sell to me your sparktech... long time already eyeing to use it.

bai "HE"is the king of miss guidance laa u dun knw ke? "HE" always nyanyi the wrong facts laa..

bai, kasi muka sikit lahh....your sentence so funny

ops, i where got sparktech bai , lariii lariii

just dun want people to get the wrong idea bai..later people engine blow how?haha

abg JO, sparktech jinkl"WAYANG" jek lebey haha..
p/s: u want kerr? can order maaa kekekeke..

hahahha..no arguement about that for sure!!
lawak..lawak..

humm... we cannot simply put high dwell time to get the power spark.. each coil has it own dwell time setting. For example, LS2 coil need 5ms signal pulse width from ecu.. 5ms is it saturation point... going above 5ms dwell time will not generate more spark, it will only generate more heat & short it life span. For evo coil i believe it saturation point is about 4ms.. this coil charge time is important whan you play with high RPM.. see below why dwell time is critical at HI RPM :

1000rpm : engine take 60ms to complete 1 revolution
3000rpm : engine take 20ms to complete 1 revolution
8000rpm : engine take 7.5ms to complete 1 revolution
9000rpm : engine take 6.66ms to complete 1 revolution
12000rpm : engine take 5ms to complete 1 revolution

wasted spark = 1 revolution 1 spark
sequention fire = 2 revolutions 1 spark

sequential fire give more time for coil to rest .. example... at 12000rpm wasted spark have only 5ms time.... sequential have 10ms ...

so you must find coil that can full charge below 3.5ms(need 1.5ms dead time.. dwell time + dead time =5ms) to run 12000rpm with wasted spark.... if not your coil dun have enough time to charge & cause weak spark & coil heat up....

so the solution is CDI... CDI only charge coil below 1ms & can give full spark power!! coz it give about 500v in a short time to the coil....

jo1 said is correct ... no need to play with dwell time with CDI... just put 2ms (if have standalone) ... the lower dwell time set, the longger ecu life... coz low dewll = low heat..

ecu --5ms--> cdi --1ms--> coil
ecu --2ms--> cdi --1ms--> coil

so you see above... dwell time to cdi not give any effect.. but cannot lah put so low like 0.5-1ms... must see cdi spec. it happy with how much dwell time...

kelantan sifu speaks edi....when my car done, we tune on the road ok? hehehe

sifu?? no lah... if i'm sifu my car not make trouble anymore... she always make me sad.. kekekeke..

want tune... no prob.. emm but why?? you just rebuild engine right.. just use old mapping lah.. we just check afr only... if lari banyak... than tune lah.. want to touch-up got password.. huumm sayang jugak maping lama..

or wanna play stroker?? kekkeke

how i wish there was dynatec arc 4 channel :P

just buy 2 unit dynatec arc 2 lah.... can run sequential for 4cylinder... kekeke...

dynatec can direct wire from ecu..... no need ignitor module....

huhuu if buy two pieces , tht price sure i go for M&W :D

have to agree with jin too..TQ nan and Jo1 for your explanation somehow..
these kind of accurate infos that all of us need in this forum

i put my respect more to people who DO know what they are talkin about..and at the same time maintain their humbleness :wavey:

last thing we need is so-called "certified" tuner and forumer who keep changin nickname and workshop name every year..makin an excessive claims without proof and provide a misleading infos most of the time..

You the man!!! hahaha wut can i say more.. sumtime people like to bark only but "tong kosong"

Jin: dynatek arc 2 cheap only ler.. 2 dynatek still cannot compete with 1 M&W lerrr.. huhu
p/s: i thought ur M&W arrive edy rite :p kekekek lariiiiii

hehehe price of M&W , err can buy big turbo redi :P
