I was just looking for some input on if I should just get a new msd cap and rotor or if should go LTCC?
What do you guys think?

 

ltcc. some will say msd, some will say oem. it's like asking eveyone which color shirt you should wear, you'll always get different answers.

 

ltcc no more opti problems ever again..

 

To bad you still have the resolution side to deal with. On the other hand I havent had any prolems with my opti in 5 years.

 

Yeah most of you guys seem to ignore the fact you still need an opti, and that if the LTCC "fixes" the problem all you needed was a $100 cap and rotor.

I have never had an opti problem other than routine cap and rotor wear on one high milage car, but it is a cap and rotor and those are wear/tuneup items, another detail most seem to ignore.

 

never heard of the LTCC.. What is it? and what does it do? or supposed to do.

 

if it doesn't eliminate the opti all together my thinking is just rebuild it with the MSD cap and rotor (built in O-ring) and drive the bitch!

 

It is a multicoil system that handles the spark distribution duties of the opti cap and rotor.

I do not believe such things are necessary, BUT if you do this is a well designed system.

 

built in adjustable rev limiter / two-step built in adjustable N2O / boost retard
in other words no need for a msd or mallory box.

 

In the 12 years and 120K miles I've put on my car I've only ever had two optis and the one of them is the original and still operational after the rotor screws were treated w/ loc-tite. The second one on the car now has never been opened and working great.
After reading some of the debacles of the LTCC I just don't think it's worth it.

 

LTCC + Dynaspark Gen III = the closest thing to perfection for a LT1.

 

You are kidding right? You are talking abnout $1200+ and it wont perform any better.

 

There is always the option of the Ford EDIS and LS1 Coils.. but my opinion, it isn't worth it unless you're doing something else with the motor. My opti is vented, and is going on 160,000km no issues. I'm swapping it out for the EDIS and LS1 coil packs because I'm swapping in a megasquirt computer and Wideband O2 sensor for more control.. And even then, I really don't have to but just want to do it. lol

 

From a performance standpoint, having a separate coil for each cylinder gives each coil more time to recharge between cylinder firings. This provides more saturation time for a hotter spark, especially at higher rpm when firing times are greatly reduced. The result is fewer misfires, cleaner combustion and better fuel economy. Now whether you need the hotter spark in your setup is the question but there is a performance advantage over a single coil setup.

 

There is a vast difference between what is technically "better" and what actually delivers benifits in the real world.

A multi coil system is technically better but the real world benifits are not particularly substantial, not at our modest level anyway.

Have to remember when OEMs implement this sort of thing a .1mpg gain is HUGE for them on the corporate level.
