just got msd ignition
#16
ok i understand and agree with the point if your misfiring due to your stock ignition not being able to keep up you need to upgrade but i guess we are just not going to agree that upgrading your ignition system when you have minor mods is not useless so lets just agree to disagree on that.

ignition and air metering are two different things. There is absolutely nothing wrong with the stock ignition system unless you're building a full blown race engine. I used the RX7 AFM because it's proven to give high RPM gains, and in my case, it did. I got 2.5hp at peak and 5hp at 7400RPM. What gains do you get from an MSD ignition? Absolutely nothing. I can also tune the AFM to richen or lean out my A/F ratio as I need it. Why the heck would I want to LOWER my rev limit for no apparent reason?
The kind of ignition control you need is the kind you get from a full stand alone engine management system. Where you can control ignition maps at every RPM and load. THAT will give you gains. When the stock ignition system gives ENOUGH spark, you gain nothing from having TOO MUCH spark. Power comes from control WHEN ignition happens, not HOW MUCH there is.
If your stock coil/plugs/wires/sparkplugs are crap and you're misfiring, then get an OEM replacement and everything will be back to normal. In the mean time, no-one has explained to me why a mostly stock engine needs MSD ignition.

well like i said we all have our own position on this thing. thats one of the nicest things about cars we can all do our own thing as long a we are happy. some people like bling others like speed and the sleeper look, yet others like both. debates about it are fun too but when i just goes back and forth like this and the same points are being made in every replie its time to agree to disagree. so lets just end this and if we need help with something else we can post it and we can all help each other, after all this is what this forum is for.

Yes, I agree with you 100%, but you still haven't given any reason why replacing the stock ignition with MSD is of any use whatsoever. If this board is for everyone to be able to help each other, then they should know as well what the advantage is to that ignition if they should one day want to try it. But if, like I believe, it's a waste of money, then they shouldn't bother.....

Upgraded ignition just creates a triple spark. Aftermarket ignitions made a big differents in HP when contact disties were used way back. Newer disties are NOT contact, therefore the voltage served from the coil is a lot higher than it used to be w/o risk of damage.
You won't notice any difference vs an up-to-par stock setup if the rest of your car is stock. especially if you're still using a stock coil
I have an MSD 6a w/ Blaster SS coil for two reasons:
1.) The ignition is the only thing on the car (power delivery wise) that has not been upgraded.
2.) I'm running hotter spark plugs
3.) I wanted tripple spark under boost conditions to make sure everything is burnt up when my timing retards.

Very good. At least you have a valid reason for it. So many people are stuck in the ways of old, where big V8s NEEDED aftermarket ignition. People don't realize just how good new ignition systems are.....
