Almost makes you wonder if the box itself has a problem. Only one I know that could tell and fix would be Bob but he seems to be on another planet right now. Sorry, dude.

Shon Herron

If the white wire was hooked up incorrectly and you tried to start the car, the box would be messed up and need to be sent back to BOB.

Oh thats great news. I am beating a dead horse. I have tried everywire on this car for 3 weeks now! Great time for Bob to be MIA.

I totally forgot about it frying the box when you hook it up wrong. DOH.

Sounds like that should fix your prob.

Do I need to keep trying to contact him first or just ship it to him with a note?

Good question. I would send him an email or call him and say it is on the way and reference the CZ28.com boards discussion about this and put a note in there referencing all of this too.

What you going to loose? An LTCC box you cant get to work anyway....

Well I found out some info on Bob, it seems he is doing business with Full throttle speed. If anybody needs to purchase one that is where you need to go to get it. They have a tech line and a tech website that Bob monitors @ www.fullthrottletech.com. I called and spoke with a Mike @ Fullthrottle and he said it is possible I messed the box up trying all the wires and offered to check it for free so I will send it in to him and see what he thinks. I also asked him the differences between the 94-97 cars and he said the box was the same but he thought that the opti tail might be different. So who knows.
But they seemed real nice and should offer alot better support with the LTCC than Bob on his own.

Full Throttle Speed

I just spoke to you on the phone. Ship it to me with a note so we can test it. Tech info is eesy to get on www.fullthrottletech.com. Bob will answer there. Here is some instruction:
A – Low-Res OPTI signal [4x]
B – Hi-Res OPTI signal [360x]
C - +12 volt signal for logic circuits [ Switched IGN]
D – Ground for logic circuits [ RefLo from PCM]

E – 2-Step Trigger Input (Yellow) > Switched + 12V, energize this input to activate the two step or retard.
F – EST input from PCM (White) > @ Ignition module.

G – Cylinder 2 Coil Output
H – Cylinder 4 Coil Output
J – Cylinder 6 Coil Output
K – Cylinder 8 Coil Output

M – Cylinder 7 Coil Output
N – Cylinder 5 Coil Output
P – Cylinder 3 Coil Output
R - Cylinder 1 Coil Output

The OPTI Signals connect inline at the junction of the 4 Pin OPTI – PIGTAIL.
INSURE that The Production Pigtail has no corrosion or Defective Connections
This is on the top of the engine on RH passenger side (usually near Purge SOL Valve )

At the coil ends of the harness are Pink and Black wires for “Coil Power”
Ground the Black wires to the Engine Block as close as practical to the coils,

IT IS_ ESSENTIAL THAT_ GOOD GROUNDS ARE PRESENT.

Connect the Pink Wires to the Pink w/Black trace wire that formerly fed the LT1 single coil.
Some models use a pink wire here. Verify 12 Volts key-on to feed the pink LTCC wires.

*The Production Coil and Module are No Longer Used .

The LTCC Current Draw is 16 Amps Net.
The vehicle Coil/Ignition Fuse_ Will need to be increased in size.
Recommend start with a 20 Amp.
Do this PRIOR to Powering up the Ignition System.

There is a 4 Position “Mode” Dip Switch inside the unit that has the following functions;

Mode 1 . Off=Soft-Touch Rev Limiter ; On=Hard Cut Off Rev Limiter
Mode 2 . Off= Energize 2-step Input to Activate ; On= De-Energize 2-step Input to Activate
Mode 3 . Determines 4x Low-Res Decode Mode. Off=rising edge, On = Falling edge (Leave this off)
Mode 4 . Off= N.O.S. Retard Activated by 2-step Input ; On = Low Rev Limit Activated by 2-step Input.

Problem is on 97 cars the old coil plug is different than on older cars, I dont have a black with pink trace power wire. Mine is Orange I think that has 12v on it. So thats what started this whole mess. I will ship it out Tomm morning. Thank you again for your help!!!!
