Choosing a ignition box
Just thought id do some poking at this before i bought one. I was looking to get a msd 6al to replace this duraspark ****, and i was just wondering if there is a better bang for the buck out there?

the digital 6 is nice. a little more expensive but has room to grow. i believe it has a 2 step built in as well as a few other features that the 6al doesnt have. i have a 6al and when i decided to start using a 2 step i had to buy a $70 box that plugged into the 6al

thats what i figured it did. thanks
to the OP, if you need a 2 step and/or start retard, get the digital 6, if not, the 6al will work. you could even get the 6a and save some money. iirc, the stock rev limiter is 6250 and unless you have a way off lifting that, ie some type of ems, you dont need a rev limiter from msd. for me i have my pms rev limited set to 8000rpms (so it will never activate) and use the msd box as my rev limiter set to 7000rpm after i dyno it i might set it to 7500 cause the car seems to pull all the way to 7000 when the limiter kicks
so in other words, the best bang for the buck box, will be determined by how your going to use it

The Mallory Hi-fire 6 box has everything the 6AL has plus a 2-step with a start retard. And I believe its the same price or cheaper. Plus you dont have to buy all those RPM pills as you just use the arrow keys on the front of it to select what rev-limiter you want.

Ill have to look into that one. I had a Hyfire IVA on my last mustang and it did pretty good...

depends on the motor. a high compression or power adder motor will see more of a gain. so will a motor that has trouble burning all of its fuel due to atmospheric conditions such has high humidity or high altitude. a bone stock mustang at sea level will see the smallest gain. one benefit of the 6al as well as all ignition boxes is that they keep coil output constant. as rpms increase, the coil signal weakens. ignition boxes take in that weekend signal and holds it constant throughout the rpm range ensuring the spark at 6000rpm is just as strong as it is at idle
