coil + cdi = cop? - part 2


ok,
after doing sum reading, meet few peoples, having discussion bout their experience, sum r lucky, and sum (maybe add a quater part lagi kot?) r not that lucky with the china bosch coil. while i'm doing sum calculation and thinking, no warranty, price r like..ermm..not that cheap..and what happen if its misfire? ahh...ur mechanic salah, u didn't wired it up proper, u r not well educated enuff..off u go with broken heart and, $$..goodbye la..

few emails to bosch stated that bosch coil r mostly made in china now. even tho they do provide info of primary and secondary resistance, but they unable to provide me the turns ratio ,max voltage and its inductance of bosch coil. they said it can't be reveal coz only for technical engineer reference..wohooo..while others coil manufacturer do stated all the info. way to go :P (don't worry, i do save the email just in case)

after going through alot of discussion, dwell time plays a major role in standalone whenever u r fitting a type of coil. each coil manufacturer has different setup and knowing it is vital when putting input in the standalone. could this be the causes of misfire? hehehehe.. so i'm not going with the bosch coil, since i need to order it if i ever need a replacement (australian made), such a hassle man. and EXPENSIVE too..duh!

as for now, i got myself a Coil On Plug (c.o.p.), Nippon Denso, which delivered up to 40000v. wasted spark setup will be removed and i'll be running a full sequential firing (4 channel) with Megasquirt-2 (running full sequential injector firing). while, i've seen those who r running Haltech, still doing a wasted spark mode, oh man! i know, Haltech 4 channel ignition module cost AUD250..opss..! try adding it up with individual coil? way of pricey. thats why, most r running wasted spark. ya la, customer does not know about it, as long its a standalone, they'll satisfied.. kesian..

-pic of a spare 4g15 head with Nippon Denso COP, the mounting probably will ready by next week


ok next, CDI, capacitive discharge ignition, i've been reading on it for while and it seems few brand have a problem of their own. is not cheap. DEFINITELY not cheap wei :P. M&W pro14 4 channel CDI cost almost USD1000. MSD? no need to mention it. haha, as in my current plan, i'll be getting AEM Twin Fire CDI unit if my COP setup going smooth. its the cheapest available, but bare in mind, its 1 of the not-problem-free unit too. hmmm..Dynatek is 1 of the top list for 4g63, with its plug n play type, most people do like their unit. but only capable of 2 channel (wasted spark).


those who r in 4g63 arena, DSM, EVO, sure know bout Proccolinos Pizza EVO which gained 1006whp. they had just installed a sequential setup (4 channel) M&W Pro-14. last time they did run on wasted spark, n by changing the ignition setup, the gained is huge. Even Buschur evo do run on sequential.
