So i know this has been discussed before and the s2k has a great ignition system but i was just curious and looking at MSD.
Anyways if you look on the DIS-4 manual under the 8 cylander application you can see it more suits our application

Even though we dont have a v8 we have individual coils for each cylinder and thus we have 4 independant ecu wires so it would look more like the v8 diagram and not the standard 4 cyl application.

So you can see the ecu has 4 wires whit/blu, white, white/blk, white/grn
And the MSD has 4 trigger wires and 4 output wires, but only if u set it as 8cyl

So my question is anyone try this im just curious, thoughts on how and if it would work?
PICS to help you out below

 

Why?

I mean, unless you just want to talk theory or your engine is seriously built I can't see a single reason for it. Not that there isn't one... We've already got individual coil packs which work pretty well for most applications.

 

cause u can use it to retard timeing at wide open throttle which = safer run on nitrous (dont suggest a piggyback or aem, i already know i can do that)

but seriously.. i know there other electronic guys on here that can give me there electronic opinions on this too..

 

I'm gonna go with a big NO.

Messing with something just to get iffy timing retard=bad idea.

Set up your nitrous properly and you won't have to worry about timing retard.

Oh, and use copper plugs, too.

 

Do you really expect anyone on here to know more about it than MSD themselves. Give MSD a call and talk to them about it. If they can't tell you how to make it work, I wouldn't even try.

To be honest, I wouldn't try it anyway, not with other solutions available that are more tightly integrated with the ECU. Seems to me you will pay a high price for this mod. Not sure if this is a stand-alone ignition controller or a piggyback. You will either totally replace the stock ECU's well-developed ignition map with this thing (for the benefit of only a small fraction of your total driving time spent while spraying nitrous) or this thing could just fight with and confuse the ignition map in the stock ECU.

 

MSD is actually well known is all automotive sports.. Its more a piggyback.. It will act as a passthrough pretty much (also boosts your ignition signal) when your not needing it, but if you activate it for timing retard, thats what it will do. No it wont confuse ur ecu or anything. Im surprised you guys dont know much about it, alot of professional teams use this.

And setting up nitrous properly would actually require u to retard timing. Without retarding timing when using nitrous you have more chance of detonation. With timing retard you can run hire nitrous levels without increasing octane..

And yes im going to be talking to MSD about it.

 

Oh rly?

 

yea u should probully get out more.. anyways this discussion is for any electronic guys that also have interest, this is not a thread for discussion why not to use it or for people that dont know what there talking about. lets keep on course and possitive please.

 

I guess you didn't realize that my post was dripping with sarcasm.

For the price of most MSD units (especially the DIS units, have you looked at the prices of them? Seriously? because you wouldn't ask about this if you have), you could pick up an Emanage ultimate and fine-tune your fuel maps and ignition maps.


quick google of the DIS-4 http://www.blowbyracing.com/msddis4.html
$509.00.

Yup. That's e-ultimate or AEM FIC territory.

Anyways, if you're retarding your timing for nitrous, you're not getting all the power out of it that you can. Unless you're running like a 100shot, I wouldn't bother retarding timing. Even then, a properly set up nitrous system shouldn't require it.

 

Thats about retail cost i can get the dis 4 for about 250 shipped..
The nice thing about dis 4 is it used ur stock maps so there is no tuning.. which you have to factor in when you buy on of those other controllers.
And its used more for a safety then anything, yea you may not get most out of ur nitrous but our car already runs a very high timing advance and thus this would just prevent detonation. more of a safety feature to prevent misshaps that you see happen a few times on this forum. you cant really use it for tuning or anything really..

oh and feature im looking for as well, u can set a lower rev limit..
im running an ap2 motor on my ap1 ecu..
Im careful and making sure not to go past about 8600, but i would like an extra safty feature. This will allow me to lower my redline without me buying an ap2 ecu and haveing my keys reprogrammed..

It has other useful things as well, like 2-step.
