ls ignition upgrared

[s14.5gonewide]

anyone know the part numbers for the ls2 coil upgrade msd?

also is their a coilpack amplifier for the ls2 or for the ls series ignition?

as in the msd cop amplifier box or coilblaster that owrks with the ls2 truck coils?


help:)

after market coils are just for bling

x2. Stock coils are the way to go

[LXtasy]

x3. Can't beat the reliability of the stockers

[Illusions]

Many ls boards will tell you to stay away from the msd coils. The stockers are still the best.

[1998ta__1991rs]

the best coils are the truck coils, the MSD's arnt worth the money, guys are making well over 1000hp with the stockers

[Matts94Z28]

I would get an optispark

[LStang]

'''''''''''''i heard one day that there are stock coils out there with some heat sink fins on them and they are the best out of the shock but there are many making over 1000hp with stockers so i would stay away from MSD coils,,,,,,,,,,,,

I would get an optispark

:hysterical:

[Harry]

I think I would just convert it to a Carb. and be done with it. Besides that's some tricky stuff that fuel injection junk. Then you only got one coil to mess with.

Yup!


If you really want a set I saw a set at parks on Rivers yesterday for for like $850. MSD

well is thir a coil amplifier.. because the truck ls2 coils arn't cutting it.


i tried ls1, ls2,ls2 car,ls2truck,msd ls2 coil and still have the same issue. i might throw a m&w ignition on it to amplify the spark and it will also alow for better ignition on the leading edge and traling edge.

and on the dyno the msd coils worked exactly like the ls2 truck. where the ls2 car and all others acted like the ls1.


what are some upgrades the ls guys are doing? amplifiers, ignition boxes, blaster coils hei tower coils? if i had hair i would be pulling it out i have been trouble shooting last 2 days on the dyno.

That's just it, they're not. That is what most are trying to relay.

What is exactly is the nature of the problem?

[s14.5gonewide]

coil on plug setup is dieing out up top.

i have tried everything in way of swapping diffrent coils from vaqrious ls series motors and nothing helps.

so far the most reliable combo is ... ls2 truck coils with msd 8.8 wires but it still does not cut it.

i have toyed with the idea of a cdi or ignition amplifier.


the issue is not timing drift or pre trailing edge ignition. these have all been ruled out on the dyno.


the problem is at 8,200 rpms the ignition system just cant stand up and do its damn job.

[Carlrx7]

Have you tried to mess with the "Spark Dwell" in HPTuners? id also recommend stock wires and regap to .030

[1998ta__1991rs]

what kind of car do you have them on? there should be no problem with the stock coils pulling to 8200. the only other option for ls motors is doing the front mount distributor

[LStang]

i heard that most go with the front mount dist if they turn over like 7500-7800

[BigdaddyDupree]

msd wires are the problem. neil had a number of problems with them on the TBSS

[s14.5gonewide]

think we figured out the problem.
http://www.jfetech.nl/LS2-Coil

pretty much the coils cant handle the high boost(still not at target psi) and rpm's a 1000whp ls motor makes less per cyl than our car so the coil has to work much harder.. we actually started seeing timing drift from the coils(checking oms) on the top end..

we spin over 8k np the car was still making power and torque at that point. we are throwing some new ls2 truck coils. new 8.8 wires and a cdi ignition box..

the box is a dual capacitor that will hold the voltage and will also do multispark (pre,during,post) and is an amplifier

i will know mid week of the issue is resolved parts are being next dayed to the shop/dyno

i hope this does the trick.

[BigdaddyDupree]

i have the MSD 6010 box on mine but its carb, you can use it with fuel injection also with a harness.

[1998ta__1991rs]

try some Firecore50 wires on it, they should help out a bit over the msd's

[BigdaddyDupree]

i know i can get taylor 10.4's through work very reasonable IMO.

[s14.5gonewide]

i will get on it. im looking at a 25ft/100ft spool of the wire.

I'm late to the party:poke: What kinda of motor is this and what are the plugs gapped at?


I don't have miss fires @ 9200rpm and 26-30psi I haven't put any more to her so I can't say over that. I am also running my coils @ close to full dwell.


What kinda of managment system?

[s14.5gonewide]

ok so ill do a little fill in.

ive been back and forth between the dyno(nc) and home(gtown)

the ignition system is a hybrid. its a distributor based system that uses the dist as its pick up point. allot of troubleshooting has been going on. and well the walls keep closing in on the ignition system.

ls1/ls2 coils that are self ignited are only good to 1.25-1.75(on the high side) hp per cylnder. so in a v8 1000whp is a sneeze. in 4 cyl thats making 2+ per cyl the ignition system takes a complete dump. no matter dwel adjustment.

things we have done.
sheilded wire to distributor(eliminates signal interferance)
back to resistor plugs(helps keep signal from getting lost and interfeering)
thicker and better chassis grounds(obvious)
capacitor(holds volts for the coilpacks) this is more precaution to keep enough juice at the coil you would be suprised to see voltage drop in higher rpm(but it happens)

msd/tailor 8.8 custom wires(because its not plug and play)
hks ignition amplifier


on to what i have learned/figured out..
an ignition amplifier only works with dummy coils(non self ignited)

ls2 truck coils are not the right part number for the bigger coils(the newer denali 6.x is the ones you want) the rest are all the same ls1-ls2 ect ect.

capacitors are great for maintaning voltage on a high whp coilpack setup(much more consistant voltage thru rpm/load range)

the coils are maxing out no matter dwell again these are the ls2 coils with heatsink. i am upgrading to the denali 6.2(or whatever) big boy coilpack which are supose to be twice as potent as the ones listed above.

what we thought was timing drift(still may have some but nothing like first thought) is not the issue. at first thought it had plagued us but nailing it down to ignition fully is key.

we run an aem ems.. but as of monday the car will be outfitted with a haltec s2000 platnium pro. i wont touch to much on this subject just yet...

the plug are
ngk heat range 8 resistor plugs
have run 3 diffrnet sets. from iridium to inset contact tips to non resistor
gapped at 18-20
we have read the plugs for timing following the strap. the timing map is nice it sits where it should with the q16

last resort:
well the last resort would be to run a halleffect based ignition. or a timing wheel/cam trigger setup. not that it will effect the ignition system . which will really nail down the fact that the cop setup is the 200% problem. an amplifier on a self ignited coil is pointless the circitry in the coil wil only flow so much no matter the signal it recieves and in fact will wreck havoc on the dwel and ignitor. the amplifier ended up causing more ploblems than help. it was trying to fire the coil 3times in diffrent voltages which in return threw the coil signal way off. you can not amplify a signal that is internal it will noly amplify a dummy coil that knows no diffrent.[lus the fact you are amplifying a singal pre ignitor. you would need to amplify post amplifier for it to work

any thoughts?
