Ignitions

[rockinrolla]

Any info on the MSD ignition sysytems for corollas would be greatly appreciated, I have a ke20, twin aisin carbs extractors, 2 inch exhaust, 5k electronic igniotion, port matched inlet and exhaust, 5 speed with 3.7 gears in the diff(jap spec), spend a lot of time on the highway, do the MSD ignition systems make a great deal of difference ?????

Most reports will tell you that they're much more easy and reliable to get started in the morning and if you've got any minor gremlins, you'll probably find it to be a little smoother running.

 

Don't expect any real HP Gains, although you may get some.

 

Also, I did a lot of research and I reckon (although not tested) that the Crane Cams Hi-6 is a better unit than the MSD, it's a digital unit instead of some wacky analogue circuitry, and it's rev-limiter setup is MUCH better than the stupid MSD unit; MSD you need to pull out the little chips and swap them over, the Crane has a simple little dial.

 

EDIT - The crane unit is also cheaper, and it has a better timing module add on as well.

have you heard of the ultra coil by jacobs electronics as I've been given one and have never heard of it before, the car runs well and didn't want to disturb anything as I've only just got it back on the road and enjoying it, have a MSD 6al to go with it, its just the wiring but is it really going to be worth the hassle in gains over the electronic system now in use.

I've got a basic MSD 6A unit going into my KE38.

 

Picked it up real cheap off a bloke who never used it. Still brand new. Good to see if they make an improvement.

 

Tom, The MSD6 +2 (i think thats the right model) Has all digital circutry.

[Taz_Rx]

7 series are digital Slo. :)

 

Yes I think its worth it. There's several areas where it is an improvement:

Capacitive Discharge, Better starting as Tom mentioned, Much stronger spark in general, Multispark for 20* under certain RPMs and the soft touch rev limiter (chips are cheap).

 

It will replace the ignitor you're using for the elec dizzy, and pretty easy to wire up. :P

[philbey]

looking at horsepowerinabox.com.au the MSD with rev limiter (using chips what is this 1978) is 100 bucks more than the crane unit with built in dial rev limiter.

MSD has been around a lot longer then the Crane (fireball etc), I think you will find they have stayed with the pill system as the dials would be prone to self adjustment under vibration, I myself know guys that are still running ancient MSD's on their cars, 10 years ago I was going to buy the crane fireball 6 to use on my HEI ignition on the commodore as it had good features but just left it standard.

 

I'd say use the crane for your application.

[rockinrolla]

wow, thanks :bash: :bash: but has anyone tried or heard of the ultra coil by Jacobs electronics

Heres some specs on that coil

hope this helps in some way:)

[Taz_Rx]

If you read the specs....

 

.....and are capable of being driven by an inductive or capacitive discharge

ignition system....

 

This mean that they are not an equivalent of an MSD 6a or Crane Hi-6, but they can be used in conjuction with one.

Basically it just a high output coil.

[rockinrolla]

I'll give it a whirl and see how they go together, thanks everyone, the information was extremely useful and helpful. :bash: :bash: :bash: :( :lolcry:

Slo was on the right track, it's the msd 6al-2. The new digital msd 6 series.

 

I'm about to buy the even better msd 6al-2 programmable. Part no 6530. This is a fully laptop programable version that can be hooked to a map sensor to give boost sensitive ignition etc. Can have more than one ignition map to cheese from etc. Will go well on my turbo wagon

 

anyway, what I'm trying to get to is that they are certainly worth it on a worked engine, wouldn't bother with more than a factory elec ignition on a stocker. If you play your cards right and skip the middle man (over here anyway) you can save a shitload on your msd. Buy it from jegs or summit racing from the states. Especially with the dollar the way it is.

The 6530 is worth over $800 in aus, I'm getting it fro under $500 with a three bar Map sensor and shipping. Can't beat it. A normal 6al or 6al-2 is worth peanuts compared to that. Go for it !

[philbey]

under 500, tell me more. I've been hanging for a good cheap ignition controller that I can fiddle my advance curve with!

[TheNOBBLER[RL]]

Just have to look around philbey,

 

I had a look at the summit website, its huge but you get the hang of it. The jegs website is quite good as well. Pretty much like our VPW and Rocket industries but bigger and in the states.

 

I even found some companies selling them on ebay motors in the good ol US of A, due to the conversion rate at the moment ($$ is around 93c!) it makes for a cheap ignition.

 

Did a quick look around Summit:

 

MSD 6al approx AU$265 delivered (at 93c) Click

 

The Big Gun 6al-2 Programable approx AU$430 delivered (at 93c) Click

 

Crane Hi-6 (similar to MSD 6al but digital)approx AU$333 delivered (at 93c) Click

 

 

Ok, I have led this thread a bit off topic, sorry. but to finish for mr Philbey :blush: The 6al-2 Programable (pn:6530) is the ducks guts, laptop programable, you can run your existing dizzies ignition curve and use it as a normal msd with options or lock out your dizzy, set a high initial advance and program your curve back from there to how you want it whenyou want it. optional (as in you turn it on or off etc) start retard, step retard, boost proportional retard (with your own boost curve ignition map), n2o retard, can be setup to run with pretty much any single coil ignition, optional 1, 2 or 3 bar map sensor to allow for the boost retard and vac advance, multiple rev limits... the list goes on.

 

I will be running one to control my boosted carby fed slant six in my Val, I will most likely be running a 6AL for my ke11, this will give me a grouse spark to light the fire in the 5k and allow me to have an efi computer to run it when its boosted later on. Overkills my best mate :)

 

Again, sorry for the slight highjack... The info may be usefull :jamie:

i have a procomp 6al chinese copy of msd and they work just as good as msd and heaps cheaper one day i was leaning on the rocker cover and moved my hand near the coil and a 1 inch spark jumped to my hand and hurt like wow! from a points dissy they work!!! and also points don't wear out cause there only used as a trigger
