Opti alternative?
For now, I'm sticking with the opti, just bought an MSD unit.
But for those looking for an alternative.
Getting the dash to work might be a real PITA though

There has been quite a bit of talk about this over on CamaroZ28. The LSx computer certainly has quite a few advantages over the LTx stuff, in terms of CPU speed, tunability, and of course the coil control. Last I heard they hadn't finished working out the reducer wheels yet, but if they got a bolt on setup done it could be a very doable swap. I think this is more realistic than swapping over to something like a FAST setup.
If you just want LSx coils, though, the LTCC package works very well.

are they still selling the LTCC?
Been posts about them not.
Besides, you still need the opti for the timing signal
With this you don't
But if you have the later cars, the dash won't work right.
Which is also a problem with the LSX swap.

I'm not sure if they are or not. I got mine a while ago. Yes, you do need the opti, but at least there isn't any spark going through it. Don't have to deal with those long plug wires or crappy cap and rotor. With the LSx swap you need to install a Vortec distributor for the timing signal, which means drilling a hole in your intake manifold. One possible solution to keeping the dash happy is to leave the old PCM in place to run the dash, but let the LSx PCM control the engine.

Nope only time there is an issue there is when it gets rusted from moisture ingress or other parts(rotor) breaking. The optical sensor is very reliable. The cap and rotor are not.

I started with a Dynaspark, but the rotor flew apart on it. I'm now using their GEN III which removes the high voltage side of the ignition from the opti. http://www.dynaspark.net/products/ The Delteq coil setup http://www.delteq.com/products.htm seems to be working great (I'm sure the LTCC are as least as good). A DFI gen VII is running the engine, but is piggybacked on the stock enigine harness so everything else works right (speedo, ASR, gauges, etc..)

The optical section is actually used on several other cars and works pretty well (most of the time). A lot of issues, as stated above, come from ozone (generated in the cap by all the high voltage arching around) and moisture corroding the cap and rotor. Also, moisture can cause the spark to jump all around and do weird, weird things.
