1jz ignition

[thechuckster]

chris: yes - sounds like your ECU does dwell control and the LS1 coil packs have dumb igniters. My earlier post is wrong - i'll edit it.

[chris davey]

ok, so that means it is a compatible thing then? One last bit of confirmation is required before purchasing

[thechuckster]

i'm just guessing - i'd get a professional EFI installer (e.g. sideshow?) or a Wolf expert to confirm it (perhaps completing that deal with the exchange of beer/money in return for genuine advice)?

some clever google searching might turn up more info on the LS1 coils.

Is quite likely that the LS1 coils are mentioned on msefi.com as well.

most igniters are dumb

first thing is what do u exactly want to do
the whole post has gone from one extreme to another
and the main post has been forgotten

i hate wolfs but ill try to help

u can run the 6 coils from the 1j
and the 1j ignitor

what u do is pair the wires up that go into the ignitor
so 2 coils will get fired on the ignitor at the same time

if u want a better option throw the 1j ignition crap away

get the wolf to trigger a cdi then the cdi triggers the coils
this way the output of the cdi fires 2 coils
not the input like the 1j ignitor

anyway goto the autronic website it has afew diagrams of how a 6 cyl chould be wired

its all the same priciple just think of yr wolf and not the autronic

a good setup but expensive is a good cdi costs over 500 bucks
and 3 double ended coils
1ggze double ended coils are good
mazda 13b coilds are good too

i would not worry about goin sequential im pretty sure u will not notice any power gains

u can go sequential ignition but u need a better ecu and 2 cdis
as i dont know anyone with a 6 channel cdi
so u need 2 4 channels and only use 2 chjannels on the 2nd one

but first sit down as see what u want to spend

but u might have to reprogram the ecu if u do changes

if u run 1 coil dwell might be different to if u run 3 coils

and most dumb ignitors are neg triggered where as a cdi can be pos triggered

ring wolf and ask what dwell settings u should have for the setup you will run
unless yr tuners knows (some wont know)

its not something u can guess

i have heard runnin 4 bosch ignitors and 4 coils on a 4ag20v can start to burnt coils or ignitors due to the dwell time cause at idle the ignitors arent doin much work and heat up
but when driving it hard theyre ok

alot of this shit only good tuners know so just ask around

These 2 statements are totally opposite to each other. Which is correct?

!

If you take the insulation off the ignitor wiring you will see whether this is the case on your loom. It was the case on Micks Soarer. He is a mechanic and does EFI fault finding for a living.

Your ecu must have dual triggers whereas mine doesn't, hence the trigger question. I have to modify the crank pickup on mine.

You are welcome to have a look at my info if you need it.
You could also maybe talk to Matt Kelly at Kawana(15SLO Torry). He has a Wolf on his 2J.

Sideshow, what is your opinion on EL Falcon Coil packs?

what the fuck are u all on about

gimme a stock elec 18RG dizzy and i'm happy

Thanks mate, I appreciate the help.

Basically the aim is to have the wolf controlling the ignition timing and for it to be sufficient that it will not blow the spark out at 23psi.

The 2jz guys using AEM ecu's have had problems getting the spark strength to not blow out above 17psi with stock coils and igniter. So if possible I would like to get this wired up once and for it to have no issues.

So I am not sure if using stock igniter, coils and wolf will reduce the spark strength like it does with AEM. I really can't see why it would if the stock setup is waste spark also?

10secrx7 recommended a M&W igniter and magna coils but the igniter is $1200 so that is out of my budget.

So as I see it, the options I have are

1. use stock ignition and coils (and see how I go and if it blows out then wire in HKS DLI)
2. use 6 ls1 coils with inbuilt igniters

Impossible to do sequential ignition but as long as the spark doesn't blow out then I am happy with it.

Going to have a look at autronic site now.

And will check with wolf to see what settings are required.

Thanks mate. I will have to check it out. I was actually trying to get in contact with matt with the torry to see what setup he is running. Do you have any contact details?

[sideshow]

maybe buy an msd dis4
if u r goin to run hi boost atleast get a half decent cdi

[chris davey]

I was just trying to find a price on one now

Can I run a DIS 4 with stock coils?

[jzk25]

Matt has opened a shop in Kawana called Premier Performance. Don't know any other details, just saw him at a party last week and chatted.

He prolly uses M&W cdi as that is what Chris @ PRP always used with Wolfs.

IMO you should just wire in to your existing components and get it up and working. Total cost = $0 and then you can improve it as the need presents itself.
Don't know what George was thinking with the no ignition control thing. Mick had his wired so you could run any combination(Toyota or Wolf) of ignition or injection by swapping plugs over so I don't see why he couldn't run ignition.

LS1 coils look neat, I would be interested to know what that setup would be worth if you go that way.

[chris davey]

thanks mate. Yeah I think george was doing the work to the quote rather than getting it done properly on the hush hush.

I know what you mean about the zero cost thing but I just don't really want to have to wire it up twice. Have found DIS 4 for $650 and that is what RZ from PF is using on his 700rwhp jza80. He is using stock coils and has so for 2 years, no problems

LS1 coils are damn cheap in US. $35US each. Got a quote from holden and they were $135AU each so $800 for 6. which sort of makes the CDI system seem like a better option.

[thechuckster]

if you eventually go for LS1 (or similar) coils, then importing them from a US online shop (e.g. summitracing, autozone, etc) might be the way to go. Summit will deliver to australia, autozone not yet but if you have mates in the US, you're laughing.

[sideshow]

just look at rocket industries web site and look at msd coils

think they make an ls1 aftermarket coil
but for 6 coils u will be lookin at heaps

[chris davey]

well if I can just run a dis 4 with the stock coils then I think that is the way to go. as somebody said, Titan use stock coils on their 6 second drag cars so they can't be too bad. If it is just the igniter that needs upgrading then that is what I will do.

The ls1 MSD coils were about $70US each so $600AU or so. And on the M&W site they said that using a CoP setup you can use a coil that has about half the output and still have the same strength in the spark because there is very little distance to the energy to travel.

[Mr DOHC]

did u want me to see if my dad can get some LS1 coils for u chris

alternatively, call power torque engines in brendale, they do alot of big upgrades for LS1's, they may have a few old coils laying around after an upgrade
