long story short, my fc1000 died in my gsl-se. I plan on boosting this poor motor soon, I have the exh manifold/wastegate/t04s 60-1 70a/r in a box waiting for funding for the fuel setup. So the ignition box died and I have been thinking of products to replace it with. This one came to mind: http://www.msdignition.com/Products/...ble_6AL-2.aspx

The new Digital 6 fully programmable w/ on board map sensor to retard for boost came out recently and I have been thinking of how I could integrate this in the setup. It really looks like a really solid product but the only thing I can think of is setting up zero split timing with three msd blaster 2 coils setup in parallel, one apeice for both leading plugs(direct plug, wont go through the dizzy), and the third for the trailing plugs(would be going through the dizzy), keep in mind that the dizzy will be full locked, no mechanical or vacuum advance. I have a few questions:

1. Will the box be able to handle the load of three ignition coils at absolute max 8krpm.

2. Will their be any negative points/problems/drawbacks with running zero split ignition timing on a boosted setup.

3. If this setup is bunk, is there a similar product that could do the job better or a different setup that would be better suited for my application.

Thanks for reading my drunken slurs and any input would be appreciated.

 

would dis-2 be a better way to go? or maybe if I locked up the mechanical portion of the distributor and keep vacuum advance and stock trailing setup then just ran one msd 6(non btm) for the leading to direct coil setup.

Any input?

boost should be limited to around 8-10psi due to high comp SE rotors and 93 octane... E85 would be a leep of faith in the very distant future though.

 

(killing crickets off my thread) any input fellas? Hard to spend $400-450 dollars on an experiment without any peer insight first.

 

I highly doubt any box on the market can efficiantly run 3 coils. Its hard enough finding one that will run 2 well. Buy 2 boxes and run one with the FC leading coil and one with a trailing coil through the cap. Though I thought these new boxes needed an efi system to work with.

 

I have a setup with 2 MSD 6 plus ignition boxes running to 3 Coils, which in turn 1 runs to the center of Distribution Cap and the other 2 run to primary and secondary plugs on block.
this was setup back in 1997 and ran beautifully up until last few weeks. I believe that one of the MSD 6plus has blown or something. It's red LED flashes but the other one is normal. I've been in contact with MSD and I've also changed out the following: plugs, wires, dist. cap, coils. I have purchase another MSD 6 plus box and will be installing it soon. The car starts and runs but very poorly - as if one of the chambers is badly mis firing. I have to keep pressing on the accelerator to keep it going. I've enjoyed the setup since I think it was definetly ahead of its time. I'll let you know what happens when I re-wire the new MSD 5 plus box.

Scrap the MSD idea and get an Electromotive XDI2 igntion setup.

From my understanding, it's essentially a TEC EMS less the fuel injection capability. Because of that, you should be able to run whatever coils you'd like and have full control over timing because you can define advance/retard in a table as big as 16x16, and have MAP and a crank sensor as the primary inputs. If you want later down the road, switching to a full TEC would be simple.

"The XDI 2 incorporates all the advanced ignition circuitry of the XDI, but gives the user fully 3D Load and RPM based ignition tables to create the perfect timing map for any engine configuration. Also incorporated in the software package are fully programmable primary and auxiliary rev limiters, programmable general purpose inputs and outputs, knock sensor input and Electromotive’s unique programmable launch control system."

 

I had great results form running 2 msd 6al boxes. each box ran a leading coil in a direct fire setup and I ran the trailing stock

 

Good ideas, thanks guys.

 

How much power do you plan on making once you boost? This is the most important target to know before deciding what your ignition needs are. Without turning this into a novel, I (like a lot of others) thought I needed or at least wanted a CDI setup. I used a pair of DIS-4 HOs -- one for leading ign and one for trailing. The boxes overheated if I ran them for more than 30 min, so I decided to go with something different. I did a lot of research and found out that cars run better on inductive ignition setups, unless they have such a difficult to light-off mixture that they actually NEED CDI. OEMs run inductive -- even on the boosted cars. F1 runs mostly inductive.

I switched to inductive and now my car runs smoother under all conditions. The wiring is simplified, I have less stuff in the car, and it cost me a whole lot less. BTW -- my car has about 350 RWHP. Opinions vary, but many think that you need CDI when you approach 500 RWHP.

 

hi guys

need help here. im trying to convert my 12A ignition to direct fire.

i ordered the 2nd gen coils but it arrived as the trailing coil. i.e two separate coils firing each plugs. the leading coil for 2nd gen i think uses 1 coil to fire two plugs.

has anyone tried to use the trailing coil from a 2nd gen to fire the leading plugs.?

i've seen people in magazines uses the trailing coil to fire the distributor instead but im not sure of that setup being right.

please help, im not sure whether this is the correct thread.

the coil is non returnable.

 

300 to the tire is the goal on ~7psi on 93 octane. Very attainable on a wastespark system. In the very distant future I will run E85 but the pumps are too far and inbetween where I live to make the switch. I know I will be leaving drivability and power on the table when I lock the dizzy to run boost and I am trying to find a reasonable way to have a programmable ignition without spending $1k on an ignition box but after doing alot of research it seems like the idea is pretty much a dream.

The fuel setup will be pretty archaic, holley blow through carb and locked dizzy but I think it will be pretty stout at 300 but more than that I would be pissing reliability out the window with a 9.4 na comp motor.

 

Sounds reasonable. One advantage the 9.4 motor will give you is better off-boost driveability, which will counteract some of the loss you'll see with the retarded timing.
I talked to Corky Bell a long time ago, and he liked the driveability of the turbo'd NA motors.

I considered E85, too but ran across the same issue -- can't find it.

 

Bad thing about the electromotive is you have to use their trigger.

I recently went with a M&W Pro-14/R Ignition and M&W Pak005 ferrite coils (I run E85) , sure to fire whatever you throw at it and the box itself is tiny.

$1,500 for the box and coils, but if you want something killer.... this is the setup

 

^ m&w ....... /drooling
on paper that thing shares alot of godlike traits, makes Zeus look like a punk.
That will definately have to wait till the e85 changeover.

not too many people running n/a rotors but I was scratching my head on plug choice, everyone seems to fair the #9's which I am currently running, I see alot of bad things about number 10's/10.5's on street cars. Would the compression and use of 93 pump gas deem number 10's necessary on the street or should I stick with 9's?
