Putting the distributor in the back is alot easier and alot cleaner under the hood. I have been runing a distributor in the back of the intake for about 8 months now and I wish I had done it sooner you can see pics of it on my website. www.96z28ss.cz28.com

 

Now I am confused, Did you do away with the opti all togeather or are you still using the opti portion and just using the MSD as a cap and Rotor? Several times during this post they said they where still using the low res side of the opti and if that is the case then the Delteq or LTCC is a lot simpler. It took me 1/2 hour for the compleate Delteq install from start to finish. If your system does away with the Opti all togeather including the low res side it would be a very interesting solution. Noticed you need to use a FAST system for this conversion and I would asume that is a little expensive.

 

96Z28SS nice intake!!

Do you have the measurements still?

 

I think his intake had the hole already, I need the wiring and distributor specifics on how to wire this up, what goes in the dist and what wires to put to it, any ecm changes needed? I have a 94 obd1.....anyone? Bueller....Bueller?

Could you take a MSD pro billet disrtibutor with pickup and all inside already and wire up to the ECM for the low res signal to the ECM? I'm not sure on the signal the computer needs to see or what type of signal is generated by a pickup in the MSD.

Use an ignition box; and all is well right? Throw the opti out?

 

Couldn't agree more


IF you are worried about clutter on the valve cover we have brackets that mount the system on the radiator and out of the way … most will need the high and low resolution signal form the opti to keep the pcm happy.

 

This is only easier than a delteq if you are going to run a standard chevy intake. Otherwise you are converting your lt1 intake over for a distributor = major PITA.

 

actually...I just installed it and lined everything up. I only spent about 10 hours "hacking" the intake. Yeah LTCC is nice but I had toooooo many little gremlins in that system. After racing a cobra and almost a full car length ahead him, the system decided it was going to spit on me and missed a few cylinders. Lets just say that was an easy 200 I lost

Hacking up the intake is cooler too because you actually make things that work with your own hands. Many poeple are just buying parts for their cars and paying people to put them on...wow.....loads of fun there.

 

Sorry about posting this in your thread but I need help and info.

I'd like to get some info about this as I'm having "gremlins" and had some huge nitrous bangs [http://masra.org/m9/tape1_012.mpg right click save as]
three weeks ago. What I found was the box was coding #1&3 and I belive this to be the cause of these bangs as I've ran clean on hose when no LTCC codes are present.
I've had MSD , MAGNACORE and taylor wires on the car and none cause the codes to go away. I've swaped out the coils, LTCC box with known good stuff and the codes stayed on my car and didn't move to the other car with my stuff. Over the weekend I swaped out the opti and the results were the same, still coding #1-#3. Today I put in a brand new opti in the car....
....you guessed it buy now its still giving a #1& #3 on LTCC.
Ok now I'm down to the LTCC harness and at wits end, the pinout of the harness is correct to the LTCC paperwork so its ok I'm assuming but there is one thing I'd like to confirm with yours. Before I start beliving it's something on my cars electrical system causing the LTCC to flake out from time to time.
Do you still have the problem LTCC unit and its harness or did you get rid of it?
I hope you have it still as I'd like to have you look at something for me.
Please PM me I'd like to talk with you.

 

Care to share how you wired it up to use the stock PCM?



David

 

Nothing to wire. Just run the coil wire to it, and run the plug wires to it. Leave the opti plugged in. Remove the opti rotor if you are making any kind of serious power as it may fling apart on you.

 

PM sent!

96Z28SS....very nice! I should have gotten that intake manifold and did some measurements. Do you still have them?? Or did you just measure and transfer it over to the LT1/4 intake?? A lot better than the "poke and hope" method though.

By the way...I didnt mean to bash the LTCC. Just voicing my opinion and whats happened to me.

 

Yes there is no opti on my car got rid of it all together. I had the FAST system already I had the opti, I had problems, I had the ls1 coils, I had problems, I put the distributor in it and no problems. Total time it took to make the hole in the intake and welding a piece of aluminum to get the right height was probably about 1 hour, I can't weld aluminum so i had to take it to a welder.
The distributor doesn't need to be wired to anything in my application.

I do have the measurements still.

 

No ecm wires to the distributor? The opti has 4 wires going to it from the ecm. You just unplug the coil wire from the opti, make a longer one, put it and the plug wires to the distributor? The ecm must have control over the coil then? And if so shouldn't you try to move it closer to the distributor to keep the coil wire as short as possible? Did you just buy a distributor with no guts in it? What part number was it? Did you drop it in the engine on TDC and on #1 and phase it at 0* timing? Will the ecm and it having control to fire the coil where it needs to achieve the timing it wants?

I know, lots of questions but I am in the middle of a high dollar build and want to do it on a stock ecm.


Thanks
David

 

Yes, please more info. I would like to run the distributor in back with the LT intake.
