Break-up at 6000rpm! Is it MSD BTM TIME?
I know its not fuel it starts around 6000rpm 11-12psi. Not a bad break-up but for sure not right or good. Anyone else have this problem. Wondering if i need more ingnition. Further more i want to change my rev limiter, and the box will help for that. I would not mind having the BTM as well, but then again i never have had detonation.
Anyone know where the problem is at?

The ignitions SYSTEM (i.e. the coil, the opti & THE DEWLL MODULE) were ENGINEERED around each other to do one thing spark once.
Just because you haven’t had a problem yet doesn’t mean you wont down the road because of it, and then you will find yourself chasing a ghost.
The dwell module is what controls the duration and intensity of the spark put out by the coil and distributed by the opti. This system was ENGINEERED to be a single spark system. When you plug a mutlispark ignition amplifier to a system that was not designed to handle it. Well, have you ever over clocked a processor? How long did it live? Same basic concept. The dwell module, the coil and the opti go away. all because of a box no one thinks is wrong. And it isn’t, is just not meant for the LT1, no matter how much MSD or Accel say, they are trying to sell a product, and that is their ONLY concern.

Thanks for the response. I can understand what you are saying. In the race car I use thier whole setup, i.e. their dist, coil and a 6AL. The question I have now, will I notice any difference if I take it out. It was put in before I got the car.

if the MSD has caused any one component of you ignitions system to be damaged, then when you remove the MSD it might make the problem more noticable, because the MSD might just be masking how bad it really is. Ignorance is bliss, but when the ignition system goes away, your bliss, and your money will be gone. The choice is yours, fix you problem, or be in denial about it. But what ever is done, is done. Hope this helps.

not fuel pressure. I have a GSS340 intank with MSD boost a pump 65 psi @ WOT. Why would you just replace a opti and coil? I know the opti is fine and its 2 months old. I checked the coil with volt meter its fine and Dew mod is new. I trying to find the problem not keep buying new parts and hope i guess right. Most of the part you mentioned will give a DTC anyway. The car is not mising just breaking up around 6000rpms- 6800rpms. . I could be blowing my spark out.. I going to pull the plugs see what there gaped at.I have never heard of MSD BOX hurting the ignition
Im sure plenty of people are using them with NP.

And you know what there may even be some truth in it. But the fact of the matter is all performance parts wear out an engine faster. Performance = Less engine life . Thats just how it is. But people like EvlViln go around spreading these rumors that certain parts hurt your engine in abnormal ways and scare people. The fact is performance parts in general hurt the life of your engine. Keep your MSD, when you line up with guys like EvlViln and you both hit around 5k rpms and you will have great spark and he won't. Its that simple. Oh yeah and my opti has 80k on it and I have an MSD 6AL that works GREAT! I can tell I have better spark up top(high rpms).

I didnt know the lone gun man owned an F-Body. Hey, trymez, seen any good grassy knowls?
Listen. This guy asked for advice so i gave some. in the end, it is his car to do what he wants with it. You have your opinion, i have mine, but if the words i have to post "SCARE" , then maybe the truth is what is scary. I have seen many a guy have ignition problems with the MSD and no one want to blame it. Just because your opti seems fine doesnt me it is working properly. You dont know what its doing. but when your ignition system goes out, go ahead and find some other thing to blame it on. It wont bother me. And for you information, When i talk about the MSD being a problem, and it causing havok, i am not talking about engine life (duh). No part puts more wear on a car than your right foot. No blower , no NOS, NOTHING!
But when someone says that they have an ignition problem, of any kind, the one thing you dont do is go out and put a box on the ignition that is going to push your broken part harder. You first find the problem, then you fix the problem then you go out and mod the ignition that is in GOOD condition. The MSD is not a problem solver, it is a problem creator. But then again, this is my opinion. I just think he should keep his options open to the whole system, instead of zeroing in on moding his car to mask his REAL issue.
In regards to the original post. I was unaware that you had a new optispark, you didnt say that in your original post. Next, I think you need to re-read you last post, and MSD Boost pump, IS AN IN-LINE PUMP! it is nice that you have 65 psi at WOT, that is good but you also did not mention that in your original post. And i also understood that you meant boost. I got that right away. But if you ignition system is bad in ANY WAY. or you fuel system is lacking in anyway, then that motor of yours is going to want out of there in a BIG hurry.
But i refer back to what i said earlier, if you dont like my advice, just dont follow it. You dont need to get all Huffy about whether or not the MSD is the right thing to do. Do what you feel is right. And if you beliieve that the MSD is the way to go then go.
It is your car, and some of us are just taking time out of our days with good intentions to try and help those of you who are only now going through what we have already been through. But if you wish to scoff at my advice. Than please, dont reply. Just dont follow it. It wont kill me. or anyone else trying to help you.

Im sorry but your wrong.. You dont even know what a boost a pump is, so i cant see taking any of your advice into consideration. A boosta pump is like a AMP for the fuel pump, and is raises voltage to the pump by Vacum/Boost. There is nothing wrong with my ignition(as far as i know from scanning/testing) not even sure thats the problem. I got to get some more logs and go from there. Telling people to replace everthing in there ignition system is NUTS and very bad advise. Even if that fixed the problem its a good idea to find out why it happend, and or to fix the real problem thats making your coils/optis/dew mods not function correctly.
