Then you don't undserstand the magnitude of the problem with the Opti. I suspect that the individual whose Opti has lasted 130K miles would find that even though his engine seems to run fine, he is loosing substantial power. I had the opportunity to test the power loss on my engine at 50K miles, by switching between the failing (but not yet "failed") Opti and the Electromotive Opti-Eliminator.

Please, feel free to scoff... .everyone it entiled to their opinion. I was just making a simple observation. My sincere apologies if it offended you.

 

Here is the site with info on it

My questions are how the timing retard and rev limiters work with this unit. I have a fresh vented Opti in my car, it runs well with it. My ignition isn't stock either; MSD Coil (guess I'm one of the few that haven't had any problems with the MSD coil), and MSD Digital 6+ igntion.

I NEED the features of the Digital 6 ignition. But the Digi 6 has proven to be less than reliable for me (I'm on #3 but thank god for MSD having a good warranty dept.). This seems like a nice alternative for me, if the features of this LTCC unit can really have the rev limiters and spark retard I want. I could sell the Digital 6, wiring harness, and coil; with finding the right deals on the other parts, I would not be out too much cash otherwise.

 

i bet a guy could get a system like that for under $700. really the only parts you must buy full price is the module and harness... the rest is whatever you can find in a salvage yard. im pretty sure every GM V8 99 and newer has those coils, brakets so they shouldnt be that hard to find.

anybody know what it costs for the module and harness alone?

 

Magnitude of the problem with the opti? Well I guess it could become a problem is really high h.p. applications. But

Passing IM40 dyno emmisions on a 600RWHP Lt1 with a stock opti is good enough for me..Well not exactly ...I also added a MSD 6AL in conjunction which worked just fine for me. I guess I never saw the need to switch over, since I have had great luck with stock opti's in pretty decent h.p. cars.

If I had the extra money to blow, maybe I would try that setup mentioned.. Moot point anyway considering I sold my car LOL.

 

George Baxter's 1,125HP LT1 (9.04@155 in a 3,900# car)...Holy Shiat you got a site or a video or anything of that car? thats amazing man. i know ARE has a camaro that LOOKS stock cept 4 a ram air hood and the slicks and it runs 8s (8.97) its incredible. lemme know on that car man, it sounds nuts.

take it easy every1,

Joe, copy and past this: http://www.geocities.com/reilym/LTCC/MVC-001F.JPG

Or click here

on the right side in the middle you can see two dials, one is for rev limiter and the other is for either timing retard or a 2-step, depending on how you set the dip switches.

I too was concerned about it doing everything I needed, but it does! I got the LTCC for $400 and coils for $115. I'll mount them myself. It was a no-brainer for me!

good luck!

 

Of course! Thats pretty much how it always works right?

I did not like my 94 opti, I think when everything is sealed off the 95 Opti is great, I'm happy with it and the design looks good to me. Alot of race cars in the older days had thier distributors converted to running right off the end of the cam.

 

wouldnt spark still break up since you are using the same cam position sensor? or is spark break-up caused by another part of the opti? also the opti cant tell much power you are making so why would hp have anything to do with putting out a spark?

 

I made of video of that pass.... it can be found on the video list at the "F-Body Hideout". This goes back at least 1-1/2 years ago. It was the first "warm-up" pass off the trailer. I think it could easlly have been the first LT1 into the 8's, but on the next burnout, the Vortech decided to shed a few blade tips and we had to shut it down....

I've never had a problem with my ignition, even at 634rwhp, with just plugs/wires. No aftermarket ignition box or coil.

Doing a single turbo setup now, and I'm going to try for 750+rwhp on the stock ignition.

 

I would blame it on the rotor before blaming it on an optical sensor.

 

My understanding is that they also improved the bearing support areas. The unit is also suppose to be more ridgid so I think any improvements in the accuracy at which the thing can turn will provide better, more reliable spark timing.

I don't think anyone is really scoffing, it's just that this opti-solution is not a TOTAL solution. For people to get up and cheer, they generally want a solution they know will dispose of 100% of the issues they had before. This LRCC is still using parts of the current opti and, therefore, possesses the possibility of encountering some of the same issues. Also, this is not set up as a buy-it-and-bolt-it-on package, so it needs some polishing from a marketing standpoint. People like complete kits, so they don't have to go rummaging around in junkyards or slumming at the local dealership parts dept. Also, this is obviously not a job your average semi-mechanically-astute person could complete without a hitch. I'm not scoffing at it, I just think there's a more polished solution.
If you just want to keep from replacing your opti once every 4 or 5 years, here is a cheaper and more total solution in my opinion: http://www.dynotech-eng.com/dynaspark.htm Here you are completely getting rid of the original problem (the GM-brand optispark). I realize the technology and form is similar, but the technology and form are not the problem with the GM unit, it's the engineering. This system also comes as a complete package and there is NO modification necessary (modification just means "untrustworthy" to me). Also, it is supposed to have higher RPM handling capability. I'm not scoffing at the other product, but this product is one I found myself cheering about. No, I do not work for them.

 

Phil's billet opti still uses the GM sensors. It's an opti w/ tighter bearing tolerances and a billet case. I think it's a great idea. It addresses a problem that many people have. Do a search on "opti problems" and see how many pages you get.

If you want to completely do away w/ the Opti problems, use a carb and a conventional distributor.

 

Better check some of those links again....we aren't talking about "that" Opti, but rather the stock Opti and using the LTCC box to run LS1 coils. Which I would still rather do than paying the insane amount of money for that "other" opti.
