MSD Distributor??

[zer0signal667]

hmm...idk on the msd web site, says somthing about being able to change timeing by 5 degree's. That sounds like a pretty cool feature. Does the dynaspark do that?

This seems like a useless feature to me. I figure anyone wanting or needing to adjust timing will do it through ECM tuning, as there will most likely be other reasons/needs for a tune at that point anyway. Anyone agree/disagree?

I think that the timeing ajustment feature is more for people that dont really want to dish out the money for a tune quite yet. So I think its for more stock cars and nothing too radical.

I agree. Not much use to change the global timing like that. Nowadays people tune with the computer (lets you customize for various RPMs and engine loads).

The timing adjustment feature is not for "ignition timing".... well not directly. That feature allows you to alter (e.g. - advance) the cam timing relative to the crank, while still maintaining the correct orientation of the Opti optical sensor relative to TDC.

Is that for in case you advance (or retard) the cam on the cam sprocket, then you can take it back out with the MSD to get the hi/lo pulses back in sync with the crank? Because that's something that you couldn't to before.

So when you change cam timing, opti sensor timing is also affected... and this feature allows opti position to be adjusted to counter this and bring it back into correct position relative to the crank?

Might be a stupid ?. but would changeing the timeing on this distributor be much different from changeing it on a tune then?

An adjustment at the cam gear would change the reference signal used for injector timing as well as the ignition timing. It also would change it as an offset which means that all the timing would be changed for all rpms, etc. In a program change, you wouldn't change the timing across the board like that, you would just do it where you need to. So we're thinking that if you advance the cam 2 degrees and don't want to throw off the ignition and injector timing by that amount, you could then put back 2 degrees with the MSD adjustment and all you would affect is the valve timing, which is what you originally intended to do.

Ok I better understand it now. So would it make it sorta like an hei distrubutor set up then to a certain point?

over the summer i got a $182- ignition control for $82- it rocks. i have a magazine with msd parts if u want me to scan it in...

Basically like Fred mentioned, the adjustment feature is to adjust valve timing more or less. If you want more HP and in higher RPM's you retard the camshaft.

The MSD Distributor does no good on my 97 LT1; they were only made for 94-96, right?

That writeup is referencing the model years for the Corvette. 96 was the last year the LT1 engine was used in the Corvette. For the F-Body, the 95-97 model years used the "vented" Opti. It will work on your car.

Don't get your hopes up.... 4 months since this was posted and no one has seen one of these show up for sale. Summit is showing the availability date as 5/15/06. If its like the cap/rotor, it will be the end of 2006 before anyone can actually buy the complete MSD Opti.

Alright, so instead of just throwing on the cap and rotor I bought from MSD, I will just wait a while for the full system to be released.

Thanks

Does anyone have a picture of the MSD iginition installed on the LS1 model engines? Since we have individual coils for each cylinder I am curious to know how it looks on the engine. And is it worth it? 74 dollars times 8 is pretty steep lol.
