Skids will have to wait till after dyno tuning, plus I'm not doing it on semi slicks for the sake mof a vid, so i'll have to dig out some dried old crusty 165 or something for that. :lolcry:

[untubbed_20]

Yeah alright then, I'll invest in a 12v coil soon.

Plan on rigging up some sort of dualpulse CAS and running 4x coil packs eventually.

 

Just took it for a drive!!!! :lolcry: Didn't like 3rd too much once the boost built up a bit, but 2nd wasn't too bad. f@$k ALL LAG!! :y:

 

multi-coils is not really worth it, just easier to get a old MSD 6A CDI or crane hi-6 CDI etc,

will have a way higher spark than a multi-coil setup and be cheaper/easier. Those old school

msd come up for around $200 s/h.. bargain if they work

 

I have just taken multi-coils of the skyline and gone back to single coil, YOU WANT ONE???

I went back because i needed a CDI and a single coil one is around $400 a multi -coil reliable

one(m@W/autronic 500R/motec) is $1400-1500. And the vl's make around

1000hp with a single coil/CDI..good enough for me.

 

I never has any breakdown with 23psi with the plug gapped down with a single coil etc

a CDI would have been my next move though, probally worth 10-20hp at the motor anyway.

cheers

PM me if you want a coil, they are usually $50 each, but I'll give you one in the interest

of seeing this thing going properly :cool:, ha,ha

they are bosch HEC 715's

Sorry Si i forgot you are only running candlepower ignition.that tune was AFR 14.3 at idle and AFR 11.8 or lower on max boost so yeah it maybe not liking the ignition setup.

 

Go and buy yourself a Crane HI-6 ,youll love it and like darren said,i have never had a misfire issue and they have also got a real nice softcut limiter in them.

Taz are you running identical injectors and fuel pressure to what madrolla was?

I'm not sure about that,i think they are close on the injector size and yes same fuel pressure,he has different comp and cam though i think.

As for multi coils not worth it? sorry but that just isnt true, M&W in sydney make a kit that not that expensive and is capable of killing you 115mj output it increases the input voltage 400 volts. with one of these on a rotoryincreased the HP by 30% as we could add a shit load more fuel because of the stronger burn, to get that power out of a dizzy cap you would be melting rotor buttons and dizzy caps.

 

Also the multi coils wont get to saturation like a single coil at peak revs, you don't have to worry about spark jumping with hi power like on a dizzy cap at hi revs (like ive seen before DETONATION).

 

Multi coil setups are worth every cent for performance.

[untubbed_20]

On a piston motor, a multi coil vs a dizzy with a CDI , the CDI system will be better.

 

A multi point with CDI would be the best no doubt, and for the extra $2000+ it would want to be

we are talkingabout a K motor here, they ain't worth every cent.

 

rotarys are another kettle of fish, they have very poor ignition systems, and need a

better ignition source than most motors, especially with the fat afr's you have to run to keep them alive.

 

Any link to the MW stuff, i have a PRO-10 MW CDI on my car, I can't see how they do any thing better

than that, except for there drag units, would love to have a look if they do something else, as it would

be good for water injection setups:)

Yeah I've got 315cc 7mge injectors the same as Madrolla and fuel pressure is also 30psi Felix. However, my reg is a 1.7:1 RR. Been worndering if this is and issue now.

 

Took it for another quick drive today to maccas, and ended up sitting in the drive through for ages,....and fouled another set of plugs!! :lolcry: Only just made it home! Thinking I might also put some new plug leads on it aswell, incase one of them is farked. :y:

M&W Ignitions

 

I'm unsure what you are doing, Why can't you just lean out your idle and lower load fuel values?

Edited June 15, 2008 by NickZ

[Taz_Rx]

I've tried nocking the fuel down a bit, both in the map and the overall trim. Seems to run well were it is, its more like the spark just can't deal with it and fouls up the plugs!

 

I'll have to wait till next week when I get paid to get it on Sherriff's rollers. Can come play in the mean time if you want!? :y:

 

Oh yeah, well I am gunna need at least a new coil Darren! :lolcry:

So when driving its ok,but idling for long periods it fouls up ey.

 

Just remembered that i run an O2 sensor for AFR correction under no boost load,have you got an O2 sensor.

Have you taken the resistor of the coil yet, It will be ok without it, ive used them for years without the resistor on 9v coils :lolcry:

Yeah, idling is the problem.

 

I was advised by the mechanic who will be tuning it NOT to use a O2 sensor for closed loop control, turned that off in the setting the other day.

 

Nah haven't taken it out yet Nick. Wil get some new plugs, leads and coil later in the week. And will go see Mr Sherriff shortly and book it in for next Thursday (26th).

So your not using an O2 sensor at all for AFR control down low.

Nope, don't have one at all!
