£400 for a wasted spark kit

v

£200 to replace leads,coil,cap etc.

Is wasted spark worth the extra cash.

v man

if you had wasted spark with some close loop you will see some nice mpg

so worth every penny

and all the little miss fires will dissapear

I got rid of my WS last year for some insane reason,big mistake as I ahve had a few missfire issues with the car since,big mistake,WS all the way for sure for all the reasons mentioned above.

Thanks.Lee.

On an old fashioned system such as the standard one, the distributor cap and rotor arm introduce an extra air gap into the system that we lose a lot of spark power through. Wasted spark keeps that voltage intact right to the spark plug.

It also gives us extra coil charge time at high revs as the coil has far less work to do per crank rotation due to the wasted spark configuration. This translates to better sparks.

Also, the mere fact we got rid of the distributor cap, rotor arm and the old king lead makes the system far more reliable too and much much less susceptible to damp problems.

It will also usually pick up some horsepower too, so winner winner.

I wonder what we all did before WS stu ?
A bog standard system in good order, can be fully effective, as many millions of cars including cossies have been showing.
I think it is amazingly over priced, considering the cost of some aftermarket ecu's that do this as std, V4 for example.
Most of the issues can be rectified with regular maintenance, although the amps are a common failing on the std system, so the WS kit adds another.

Why do you always jump on ANY topic about ANYTHING my company produce and try to slag it off? Its becoming really tiring now mate.

To answer your point:
The standard system needs plug gaps dropping so low that it compromises efficiency if you run anything over about 300bhp as the cylinder pressures are so high teh standard voltage system cannot jump the gap.
Think about that mate... we had to drop the manufacturers gap down to make teh system work AT ALL. Are youn sure it was up to the job?

Your millions of standard cars example is also more than a bit pathetic, show me millions of 300bhp + 2 litre 4 cylinder cars running fine with a distributor cap please.

Why do you think ZERO manufacturers have produced a car without WS or coil on plug for, what, 20 years? Longer?

Why do you think at Santa Pod the only cars you ever hear missfiring embarassingly up the drag strip are the old high power Cosworths?
Why not GT4's, Scoobys, GTO'S, Golf GTi's and Lancers of the Same Era?


I have stated my case as to why WS is better, so please tell us why I am wrong.


As for Ignition amplifiers being a common failure point, your wrong, no they are not. I think I have fitted about 25 in the last 15 years.

I suppose your going to tell us all that you have a GT35 running with a distributor cap and rotor arm with 0.75mm plug gaps arent you?

Lived with misfires as there was no option?

Amps a common failure? really? i think ive seen one fail in over 2 years, and i see plenty of Cosworths, hardly "Common" Infact id say ive seen more DEAD aftermarket ECUs than i have dead Ign amps

Ive been plauged by missfires through all my cossie days with new car rotor arm etc , changing plugs etc best mod i ever done was the wasted spark conversion never went through a set of plugs either

WongRS

iTrader: (11)

I have wasted spark and think it was money well spent, its only missed once or twice since its been on, once was when it was absolutely horsing it down with rain and the 2nd was when my plugs where knackered.
And before i had it, it was more of a case of "i wonder if i can get full boost without a missfire? oh, no, of course i cant"

ajamesc

i must admit i had 350 on the standard set up running 26psi with no probs and it dident hunt on idle

v man

i had a 2wd running t34.63 32psi and it ran fine but wouldnt do it all ady long with out misfiring

ws all the way

Papillon

Mine never misfired on stg 3 and 1.8bar 0.6mm gap, magnecore leads and MSD(not m developments) coil. I added a MSD (not m developments) 6al ignition amp when i went for more power whitch works great but has a downside of melting the dizzy cap quite fast resulting in misfires so now im tired of changing dizzys and gone for MSD( m developments) w-spark. When buying à aftermarket ECU u still need new leads, coilpack, loom etc so imo the w-spark isnt that expensive, u just need the chip and the rest you could do/get for your self but its nice to sometimes save the hazzle and time and go for bolt on bits.

Buying the old setup i had new was the same money really.

James @ M Developments.

iTrader: (2)

Try running some manly boost like over 40 psi and see how a grp a coil does then lol

Also don't forget launch control works soo much better on w/s !

ajamesc

ive never had any dealings with it nor no anyone with it so dont know anything about it but i know a lot of guys on here have it and rate it! im on autronic sm4 now

teahan

ws is one of the reasons modern cars are so damn reliable, and fuel efficient, you'll have the money saved from the fuel alone in a year or so.

steventoon

When I get some cash together I'm going to go waster spark.

Stu, is there an option if I post my ECU for you to fit the circuit board for an additional charge or is it a doddle to do?

James @ M Developments.

iTrader: (2)

We can do it for £35 plus post back mate

steventoon

ok ideal, i'll start saving, thanks James

Stu will do that for you I'm just about to send mine off in next couple of days

Wasted spark on my new car has Eliminated the misfires I used to suffer from monthly on my road car. As above it transformed ownership of a non standard cosworth, smooth and reliable

XRSTI

my 3 door has the original amp since it left the factory
(iv been in touch with all previous owners, they never changed it)
so thats 25 years of reliability
but im saving for WS anyway lol

paddyrs

mine has not had any misfires yet i have it 8 months now its 375bhp tho i want the ws and cl as it seems to be rated very high

iTrader: (2)

i doubt tabs will reply as helpfull as he is with stuff on here it seems once he slags msd off he never posts back with reasons why lol!

BRAMMER

iTrader: (23)

I'm sure you could spend the cash and get a standard system to work well (but for how long?) but i just ended up chasing sensor after sensor, then leads etc etc before i just gave up and payed the little extra for W/S, it's been on since April 2009 and I've never had an issue since - before that i couldn't get proper boost it was popping and farting and just a complete pain in the ring

In all honest reliability aside, the only thing i noticed about wasted spark is the car takes longer cranking to start lol. Made no difference to how my car drove.

BRAMMER

iTrader: (23)

Mine was terrible to start with so the difference was perfect to start with - i run mine with genuine 909 leads and 071's and it's been fine for over 2 years and fires on the button

bad boy rs

iTrader: (7)

mines exactly the same its been known to backfire on start up aswell with can be embarrising. it deos run better though although i never had problems with the coil. If youve got the 400 quid spare its worth doing but if the coils working fine...

BigErn

Had a bit of missfire on mine when I first got it running on the greys. Put a Gp A coil on, new phase sensor on a replaced the cap, arm and plugs and it never had any more missfiring at 36-36psi on the T34.63. However I would like WS for it eventually.

JamesH

iTrader: (21)

EXACTLY the same as mine was! Used to take an age to start after going WS

boost mad

iTrader: (8)

And mine too,

BigD.

I've not got wasted spark, but the boys from msd on here have just sold me on the idea! lol
converted!
WSFTW!

wattie

so, if i posted my ecu to msd, and they post it back with the chip fitted and all the rest of the gear to make it work, how much is it?

ram

iTrader: (4)

at high revs and on the limter mine missfires all over the place. just deciding wether to spend just £100 on a new rotor and cap, grp a coil and grp a coil loom. which should do the trick as ive never replaced mine so could be well old. Or do i spent another £300 for peace of mind? £400 is a lot of money.
