what i would like to know is what would happen to my motor or what kind of damage would my motor sustain if my msd ignition box were to suddenly fail and stop working while i was boosting ?? any one have any thoughts on this? i thoguht maybe the engine woud blow from maybe detonation or something but imnot sure thats why im asking you guys

 

you would hydrolock on fuel...

 

are you serious? you really think that would happen?

 

You would not hydrolock on fuel. You might backfire pretty bad though.

 

same thing happended to me.....hesistated, back-fired, and stopped. the motor was fine.

that's what will happen if you can stay away from MSD digital 6 they are know to go out a lot.

 

so what ignition do you recommend

so if teh msd fails on me even while im boosting hard my motor will be ok? just some back firing? no engine damage?

 

It shuoldn't really do anything bad... A lot of rev-limiters are spark cut rev limiters, so it'd be just like hitting a rev limiter... motor would die, no harm done.

 

ah i beleive you ar right. almost sme thing as spark cut rev limiters. thanx man

 

ive had mine for like 2.5 years now and no probs

That is if you are running 1600cc injectors at 100% duty cycle on WOT at redline

im sure your box is fine, but i am having to replace a broken DIODE on the main board in my 6A box. unfortunately since i hav already desolderd the broken diode off the board, MSD says that they wont fix it at all. and that i have to fix it on my own. but i cant find the exact replacement i canonly find one that is rated 100 volts less. so i was going to try that one. i have looked all over the country and even out of the country. england has some but they wont even talk to me so **** it. just wanted to try this replacement part and see wat happens. the worst thing that can happen is the MSD 6 A box fail cuz the part goes out. and i the BOX fails its basically like ignition failure right??? adn if i have that the motor will just die out cortect? i wont get hydro lock from fuel? i am running 880cc injectors....

 

The MSD fires the ignition multiple times during its firing duration. This gives a ensures that all of the products in the combustion chamber are fully burnt. If you are using a external coil it improves charging time, and discharge energy as well. The worst case scenario that can happen is that you dont fire the entire mixture in the combustion chamber, and you mis-fire. At worst you mis-fire, nothing more. Either run colder plugs, or tighten down the gap on the plug, or both. MSD boxes dont really do anything, the external coils do.

 

you wont misfire at all.

the car will simply shut off. I had a 94 mustang gt with a vortec setup on it and a msd setup. It decided to die on me one day on the highway. The car simply just cut off and the steering wheel and all locked up on me

coasted to a stop, spent 20 minutes figuring out what happened, bypassed my msd and it cranked right back up off the stock ignition.

If you're ever worried about it going bad just carry a spare distributor cap and stock coil with you so you can go back to stock to make it home.

 

Why can't MSD provide you with a replacement part??

 

they do that for a reason . they dont want other people working on them . all companies do it . ever try to fix an AMP . you can never find the exact value parts as are in it . PITA if you ask me , i gave up working on that stuff for that reason

they do provide you with a replacement part. When my msd on my mustang went out, I simply called them up and they said to just send it in and they'd send me out a replacement ignition.

they sent me back a complete msd 6a ignition in retail box with wiring and all even though i only needed the unit itself.

only thing i paid was for shipping.

 

yea they will do that if u havet tampered with the inside of the unit.. i have opened the unit and took the broken diode off the board with a solderign iron. once i said that they were like nope cant help you. i was like wow. so i guess i shoudlnt have opened the box lol

 

thats why most things you get from companies say for you not to open them. and that's what you get for playing around with it. shaaaammmmeeeeeee on you.

"warranty void if cover removed" etc are on things for a reason

 

becasue i thought i could fix it lol. and i can its so simple i just catn get the damn part lol.

i've had it happen to me once...nothing bad really happens...motor just shuts down...just make sure you're not in gear for too long...you'll screw your motor up.

 

yea any time my motor has ever had somethng wrong the first thing i do is press the clutch in and coast. its out of habit
