sifos..what is this? how does it help our car??

what does this do and how can it help?? took out of a levin with 20v.. :D

As you can read, it's for the ignition system...

useful thing la 4 netter ignition power ma..
can add up hp up to 15hp..
no la jus kidding ...

multiple discharge? waste spark system? *scratch head* i oso wanna know lah

 

[rollakid]

sound to me like an ignition system to simulate twin spark system like in the honda iDSI, but using 1 spark plug... *scratch head also*

*scractch until got blood*

what issit ah?

Multiple Sparks (Restrikes)...
Because you never get something for nothing, the quicker, hotter spark of a capacitive discharge ignition system results in a shorter duration for each spark. At high engine RPM this is not a problem because the spark must occur very quickly. However, at low engine RPM this shorter duration can result in poor performance because cylinder pressures and temperatures are low and air/fuel mixtures can be poor. To combat these conditions, Holley Annihilator ignition systems will fire each spark plug multiple times (restrike), for 22-1/2° of crankshaft rotation, up to 3,000 RPM, to insure the air/fuel mixture is fully ignited. These multiple restrikes occur automatically whenever engine speed is below 3,000 RPM.

I got this off holleys website. U really got yourself a gem here. Suggest u find the wiring diagram for it and use it. Things like this sure would temp Wong sifu. hehehe

wah.. syok lor.. so basically its a must have for those running super high rev engine?

 

[ahle@]

u get the halfcut from cheras near kajang tool right??black levin with Jasma extractor..

wan sell it or not:P...PM me lo if u want 2 sell:)

 

[olskool]

thanks for the reply guys...

michael..so what you're saying is that it ONLY helps on the low revs?

ahle@.. no la..the halfcut straight from contenna.. owner wants to sell it seprately and don't wanna give goodies with the halfcut as the prices are low....

 

[limandy]

looks like a pcs a aluminium... throw it away or sell Recycle to get 50 cent

multiple discharge ignition

there's a thread at www.club4ag.com that discuss the very same thing.

it's in the forum under the technical talk > electricals > DLI with Japanese MDI System on 4AGE *pic*.

i don't understands one bit of it. :)

 

[Culo]

Where did u get this ? i think i got this piece connected to my handbrake lvlers underneath my seat too

 

[rollakid]

whoa... first post say that MDI thingy cost USD900 0_o"

 

[olskool]

in that post....it's for a 4AGEU and 4AGELU... what engines are those?? i think it's different as this set does not come with those coil set... it's only the device itself.

 

[AE80TypeD]

4AGEU and 4AGELU are simply USDM designation for the cars sold in the USA with 4AGEs

L denotes that the engine is in FWD form (transverse layout). 4AGEU might apply to 16Vs in 86s or old RWD toyotas but not for 20Vs. All 20V comes in L layout whether the chassis plate denotes it or not.

U is a code for US spec engines. u may also come across 4AGE-C which was once used for California only, since they have the strictest emmision laws in the world. i dont know if this 'C' code is still in use by toyota US, but California is still very particular about engine emmisions.

Tony, i dunno how to say or describe it, but when u read what i found, i mean u could understand it right? I believe even no matter how good a stock ecu is, things like this generally pacthes up the ignition system to be better. I could only dream of having an electronic ignition system with my carbies. hehehe. That is why ECU also have revisions. If items like what u found is installed in any engine, i believe its for old revision ECU. But for holleys case, i believe its for daily drivability. Just note at their highly aggresive tuning parts. Yummy!!!!
