So I've been tossing around of buying a Digital 6+ MSD box to replace my 6a on my MSD_DIS set up. It looks as thought it would hook up just like the regular 6A does. I'm soiing the idea around then I figure I can run the 6a through the dizzy. No money not being a factor do you think it might be bennificial. I wonder if it could fire the DIS coil better than the regular 6a. Give me thought's. I don't want any F&F 17y/o posting in this thread unless you know your electronics and have allready experimented with or have direct experiance with it.

Hmmmm, very interesting. Some has had to have done it already......anyone?

 

Well there are only 3 know people who have even done the MSD_DIS setup. Myself one other guy on here and a guy with a tryumph 13b. I was hoping that there might be someone on here that had more muscle car experiance than I that might've plaied around with both the 6A and the D6+ and could offer some first hand experiance...

 

cough...

 

I can tell you that my Tuner - Crispeed prefers the 6A/6AL's on the rotaries because they are more robust, and have better dwell than the DIS box's.

Money being no object - I opted for 3 6AL's with my Haltech setup.

 

MSD customer service sucks. I sent them an email 2 weeks ago then again on tuesday and still no response. Can you believe that crap. My main question is weather the digy6 would charge the DIS coil better. Since it does 135 millijoules as opposed to 115, and 55 volts primary as opposed to 480.

 

So I thought I'd bump this since I hate wasted bandwidth. I got into a pretty good conversation with some muscle car tuners today. Turns out the next big thing is the Mallory VIA ignition. It is better than the MSD 6A in every way, and it's cheaper. Plus it's digital instead of analog. that means it uses less power and is much more accurate. You can get them on Jegs for $130, so I'm going to pick one up for my next CDDFIS-DIS. It's not as good as the D6+, but Mallory has a model similar to the d6+ that is yet again better and cheaper than MSD's equivalant. Last year Mallory ran this promo:

Wanted Dead Or Alive - Mallory Ignition has put a bounty on MSDs head, so to speak. Mallory's latest promo promises to pay a $25.00 - $75.00 Bounty if a customer buys a new Mallory Digital Ignition Box (6852M, 6853M or 685) between April 1st, 2007 and December 31st, 2007, and sends the original purchase receipt and the bar code label from the Mallory package, along with their Dead or Alive MSD ignition box, (postage prepaid) to: Mallory Ignition - MSD Bounty, ****************

In return, Mallory will send a a $25.00 - $75.00 Bounty check, depending on MSD box returned: $25.00 Bounty for MSD 6200 & 6300, $50.00 Bounty for MSD 6320 & 6420, or $75.00 Bounty for MSD 6350, 6462 & 6520.

Compared side by side, the Mallory 6A, 6AL, and 6AL2 have the same wire color coding and mounting pattern as MSDs 6A and 6AL analog ignitions for simple replacement. However, the Mallory 6AL Ignition has 1 stage of rev-limiting that requires NO chips for adjustment unlike the MSD 6AL that requires extra-cost chips for specific RPM settings. The Mallory 6A, 6AL and 6AL2 ignitions also have 19% more spark energy, 10% more primary output voltage and 40% lower energy draw than comparable MSD boxes for maximum performance and reliability.

Here is a derect com[pairison of the Mallory to the MSD as well FYI it's a PDF:

I'm not promoting Mallory I'm just letting people know that there are options besides MSD. Mallory, Crane, Jacobs, and Summit now has a $100 digital box... I think I'm going to get a Mallory boxand Crane coils. I'll do before and after dyno runs as well.

 

i was thinking about trying out the summit digital ignition box to see how it does... i havent heard anything about them, but they seem to have better numbers then the msd and jacobs boxes. Plus for a little extra $ you can get the one with the built in rev limiter and still be cheaper then the msd boxes

 

NOTE: This is a leading discussion only Trailing is "stockish."

Well I'm trying to rethink the coil situation. Before I was using the MSD DIS coil, but I think there has to be a better solution. The best idea I had was to use 2 VI-A boxes shareing the magnetic pickup signal and letting each box have it's own coil. I know that using 2 coils on one box will split the voltage weather or not I ran them in parallel or in a series. That was what led me to the DIS coil. the only thing I didn't like about the DIS coil was the mountaing and it kind of had to be jimmie rigged. I honestly have no idea how the DIS coils work and how to hook it up all I know is no matter where I plugged in the wires it ran. So that's why I'm considering a different solution. My idea of using 2 boxes and 2 coils for the leading would in theory allow both boxes and coils to operate at full capasity. But, my consern is splitting the magnetic pick up signal to two boxes. Would or could that cause an issue? IDEAS!

 

I have my leading Mag pickup running two msd 6Al boxes and it works great. I'm pretty sure it will work for you as well. I just mounted my #1 leading coil on the side close to the plug.
It fired up right away and has a way better idle.
Trailing was left stock other than msd coil and wires.

 

UPDATE: Upon further research the Crane Hi-6 puts 1,200 Millajules of spark out put. While every other box only does 125-135 MJ. LOLZ I want a crane box now. I just don't know if I want a crane cams sticker under my hool LOL!

 

WOW! that a huge diffrence.
I wonder how much better it performs and the price diffrence.

 

The Crane Hi-6 is right around $300 new a MSD D6ALis $400 new and the Mallory VI-AL is $150

 

Well what ever you end up buying this kind of setup works well for me so far.
Not too too much testing before I started tearing into the motor though...

 

Where is Jeff20B when you need him. lol

 

I may be wrong, but seeing how the specs are identical, I think the Summit box is a Mallory 6AL with a Summit sticker on it.

 

I was thinking the same thing.

 

Has anyone ever ran a Crane box? Rotary or pissedon?

 

Hmmm this is very useful information for me.. was considering upgrading my stock ignition coils to MSD A6L's and figure a way to still use my Dizzy...

Let me know if anyone has done this before and I am really interested in that Mallory system now...

 

Before I set up the direct fire setup I had two blaster 2 coils hooked up in the stock way then I hooked up 1 MSD box to the leading by taking the wires off the coil and wiring them to the small red and white wire on the MSD box then the small orange and black wire went to the coil and it worked great. gave me a much smoother idle and easier cold starting.
I do recommend to try and go dirct fire though it helped with both idle and cold start up even more.
Direct fire made extreme cold start up (-20C and lower) way better.

 

I have been looking at the summit box as well. Some good hard input it needed in this thread. I need stronger spark for my 12a turbo. I dont think the the fc coil is doing it!

 

Anyone know more about millajules of spark, and if upgrading from my MSD box to the crane Hi-6 Would be worth the investment. My MSD Box has been in 13 cars now and is 10 years old. I'm looking for an excuse to upgrade.

 

1985 Turbocharged Mazda RX-7 GSL-SE "Cosmo" 13B-RE

here you go check this link out i hope it works out for you. oh yeah i am looking for a video that i came across with thcat set up on a 13b the key words are above. he has some bad *** mods.

https://www.rx7club.com/1st-generation-specific-1979-1985-18/msd-coil-set-up-758025/

 

I'm not having coil issues and right now I'm runnign a stock FC coil anyway. I.m trying to find out if people have any experience with ignitions other than MSD

 

i need help running a turbo I want to run 4 msd blaster 3's turbo 2 crank angle I already have 4 msd 6al laying around as well as the msd blaster coils...wil this work will it run and how do i go about wiring this?

If not that way Can i runn two blaster ss coils and 3 HVC-2 coils and the three 6AL'S

will that work?
