i read a post by another member saying that the 685 box isnt good to constantly use with the Opti. i plan on using it for nitrous, with the retard and window switch capabilities but was wondering what people thought/heard/know about this.

 

I havent heard anything like that.

 

No particular ignition box is bad for the opti. People just like to make unproven claims.

 

If shoebox said it, it must be true!

 

Not really, but I know from running an MSD 6A for 6+ years that it's not bothering my opti. There's plenty of other people running ignition boxes, too.

 

Shoebox, where do you have your 6A mounted?

 

yep yep. hmmm, well i guess screw it then. how about mounting it? i can rig it to activate the window switch and timing retard only when i arm the system correct? so then i can mount it under the hood since i wont manually need to retard the timing everytime then huh....

 

Yes you can set it up to retard the timing while spraying only.

 

I wouldn't put a whole lot of thought into it, I have also heard many claims about aftermarket coils destroying optis as well.

 

You are right that it is unproven but wrong about people (like me) simply liking to do it. I repeat empirical as well as logical statements from respectable people because I believe they are correct. I've quoted you time and again. I simply want to contribute, help and be part of the discussion. If my passing of an unproven claim occurs it is a mistake that I take seriously and try to correct.

 

It is under the underhood fuse/relay panel. I had to kind of customize the mounting because the surface is not all flat. It's out of the way, though.
