I am planning my turbo setup and have a few questions about the optispark.

it looks like i am going to be running the big stuff 3 ecu, but i have a few questions before i get to far into it.

the big stuff 3 ecu that im supposed to order (part# BS3-004-002, per john at BS3) will interface with the optispark but it will not work if i was to switch over to a coil on plug setup (like the LS1). id need a different BS3 ecu.

I dont want to get a $2000 ecu and find out that the optispark wont be able to handle the power i want to make, which is 800hp ish. or find out that the deltec/ltcc interferes with the BS3 and thats not an option either.

but i dont want to spend the extra money on the big stuff 3 and the coil on plug conversion if it isnt needed.

i plan on running the best optispark i can get, and from the searches i have done on here it seems the msd is the best.

anyone have any hard proof as to the limits of the optispark?

anyone have a ballpark guess as to how much it costs to swap to a COP setup?

sorry for the long post, but i searched and didnt find anything that answered my question.
thanks in advance for your help.

 

Times in sig, same stock opti last 2 year.

 

Putting together megasquirt, ford edis8, coilpack per cyl. Opti GONE, entirely gone. No sensor, no distributor.

I would say rpms would get the opti before power levels. As far as ignition people have different luck. Usually tight plugs and a good coil can go a long ways.

 

I've made 700 rwhp through an auto/loose converter and gone 146 in the quarter at full weight with a stock opti, MSD cap and rotor, and Crane HI-6.

 

I will be fallowing this thread as well. What do you have to do to get the opti to work at those levels?

 

I don't think they're doing any special to the opti's to be honest. Just good ventilation. Some take them apart and put locktite on the screw and put a good seal on them and that's it. As much as I hate to go back to a single coil setup I may have to as the DELTEQ and XFI just don't seem to want to cooperate and that's really unfortunate. I'm hoping Ramerman (Rob) has better luck once he gets his adapter. If not Crane HI-6 here I come.

 

i dont think there are any problems with the optical portions of the sensor, so long as you keep it clean and dry. i would be taking the opti apart and removing the rotor so you dont have it let go if youre spinning up 7k or more (and are running ltcc), which bs3 will let you do.

i'd figure something around 750 bucks for ltcc including the coils, plug wires, brackets, etc. thats what my buddy has into his setup. not really cheap.

 

nice!!

 

i dont plan an revving really high, 7000 max.

 

are you unable to use the optical eye (in the optispark) as a crank reference for the FAST and let it tell the delteq when to fire the coils?

this is what i had planned to do with the BS3 box (if the optispark isnt good enough)

 

the delteq setup is complete and it is ~ $750, it does the same thing as the ltcc, but you dont have to source your own parts.

if i were to go COP i would go with the delteq setup.
have you seen this type of setup work with a gen3 big stuff 3 box?

 

I'm in the process of putting together a COP setup on my LT1 using a LS1 BS3 box. I having the opti converted into a cam sensor.

If you go with the LS1 box, you don't need the delteq stuff to get sequential ignition.

The place that's making it for me will likely make make some more of them after mine's done.

In fact, they'll likely post up here after seeing this.

 

With a T76 on 383 cid, you won't be going even that high.

I'm waiting to hear how this turns out. This sounds like a killer setup.

 

My opti exploded just as I was crossing the finish line

So I'd say don't go over 112 mph and you'll be fine.
