Opti that GM installed is still on my car from 1996. No issues. No bs. LTCC=FTW

 

Who says the opti is dated and irrelevant in todays world?

 

The 24x is not the end all be all. Most people who have it dont need it. For the money people need to look more into the LTCC.

 

I would agree with this. I had the LTCC. Using the LTCC system removes the arcing from the distributor. It's been said many times the gasses from the arcing is what affects the reliability of the unit, even with the later vented units.

However, I'd still go 24x today.

 

I wish LS1tech told me I didn't need 24x before I got it.

 

I don't. Mine threw a code 36 about 6 months ago. It's only 2 years old.

Hasn't been driven since. I have no desire to do anything about it.

 

Wow. Me too. Most of us who have it got it for reasons other than dealing with opti issues. Finding a tuner is one of the biggest issues with the LT1 ignition/CPU system.

 

Shownomercy and SS MPSTR, I think you two are taking this thread the wrong way. I'm talking about the guys replacing Opti's to fix a problem with their engine. Not replacing Opti's to improve it to a better system.

The LTCC, Delteq, and especially the 24x are superior set ups to the Optispark. But, replacing an Optispark with a "new" Optispark to throw parts at a problem because someone on a forum said it's the Optispark without any real troubleshooting? That's ridiculous.

Also, you guys apparently didn't read the thread as this is stated pretty clearly in my first few posts.

 

There will ALWAYS be people that ask on a forum and some 16yr old kid that knows jack **** will tell them to replace something and they will go out and do it.

IMO, if you don't do enough research/diagnostics to make your OWN decision then I don't really care if you rebuild your damn motor just because a spark plug is fowled...I will just sit here and laugh.

AFAIK, I still have my OEM opti in my 95 with 66k mi and have not had any issues. It will stay in there and only be taken out to be inspected only if certain checks determine it is in fact the opti. At which point I will attempt to rebuild it and toss it back in.

I think it gets such a bad reputation is because it is not so easy to see/remove/install. If it was on the front of the motor unobstructed where you could do testing easier then people wouldn't get their panties in a wad about working on it.

 

I'm running the super hero of opti's...Dynaspark! Five years running now.

 

I read your posts, and they are good. My comment was more for those who insinuate that the move to 24x is "unnecessary" because the opti can and does work. There are just other reasons for justification. I actually had the Dynaspark (gen 1) opti for awhile, and it performed flawlessly.

Trust that I'm no fan of throwing good money after bad in chasing down a problem by simply swapping parts without understanding the root cause of an issue. Been there, done that, so I appreciate the message.

 

One problem I had on my old motor was that the front cam bearing was worn out and would put load on the opti bearing(Early opti). I could put a brand new gm opti on an a week later it would break up at high rpm. The rotor was loose every time. Not a problem with the opti, just another bad part causing it to go out

 

A few things to point out in the OP.

The ICM does not control timing, the PCM changes when it tells the ICM to fire the coil. IF the ICM managed the timing there is no way you could replace it with a 4 pin HEI ICM and have the car run.

92-93 LT1s were batch fire not sequential.

I say it's their car if they have the money and want to. Let them, it does give the company's making/selling the product money/income.

 

Do you think people are still on forums loving their crossfire setup and saying anyone that upgrades is silly. I bet they do, smug faces and all. Or perhaps carb guys all smugly thinking about how awesome their fuel mileage is compared to a modern EFI car.

Guess technology stopped after the optispark and went backwards, least thats how LT1 owners portray it.

 

Eh not me, but then I decided the 24x kit was not enough and replaced the LT1 with a 5.3 LS.

Now I don't know what I am going to do with the LT1. It had oiling issues but it is in good shape other then bearings.

 

This was in the 1993 Corvette?

 

Edited, thanks. I forgot the 92-93 LT1's had ECM's (which would be batch injection), 94+ got the MAF and PCM and sequential multiport.

 

Sure, but now I think I should have worded it nicer.

Yes it is in the 93, but I don't have recent pictures of anything other then the poor location of the o2 bung on the drivers side swap header.

 

No worries, I didn't take it but as factual; I wasn't offended in any way. I asked for the info in the first post anyway right? It's worth pointing out. Accuracy is the whole point of this thread.

 

OK i understand how the Opti can effect all highlighted in red...but the highlighted green,you got to be making that up..right?
