24x is more than worth it. Just tuning alone is worth it. You can find deals everywhere now and if you're creative, save yourself alot of $$$.

Like Bill from BP said, if you're patient, you'll have better results. Like your wires. I bought 10.5mm wires from Taylor, custom made, $82 shipped.
I have just over $1,000 in my setup and that includes the dyno tune from Shortuning. I had to have Bill rewire my harness because I have an Impala SS. He can't get the parts needed to make a new harness for B-bodies.

But he is working on something that will change the entire world of LTx ignitions. Just too bad I'll be dropping in my LSx by then. So he'll be getting my harness back for another rewire.

BTW, OP, I have a few 0411 pcms if you're interested. PM me.

 

^^^Exactly, If you want it, Great, but do you "Need" it? I see so many builds that is your average build and someone will chime in and say you need to go 24x to make it run better. The only thing that will make it run better is the person tuning it. I see no gains in power (unless your motor makes power past 7000 rpm) When you go 24x you set all of the tuning parameters to LT specs and not LS, so why is, say 33* of timing and a 12.8 air fuel better in an LS pcm vs the LT?

 

Because I can go to a track rental with a LS1 tuner and he can adjust my heap on the fly.

If I had a LT1 pcm I would need to call some tuner in another state, hope I have enough cell coverage to download the tweaked tune via email, then upload it to my car and hope it all works.

No thank you. The availability of tuners and added expertise in HPtuners seals the deal for me. And yes, I know, some people are lucky and know a great LT1 tuner next door, but since there are none by me..

 

I'm still up in the air about it. The goals for my car is nothing more than a sprayed 355 with AI heads and cam. Finding someone to burn a tune for my '93 is getting scarce. I have someone somewhat local that could do it but then I will always wonder if it can be more refined or better with a better PCM such as with the 24X conversion. But that I'm not sure because i'm not a tuner and don't understand all the lingo. I'm not worried about ignition as my Opti will be just fine for whatever I do. I just want to know if more power could be had from tuning with a 0411 PCM compared to my '93 ECM. Also i'm not sure how the speedometer would work since a '93 runs a the speedo via a VSS buffer and not the ECM. I assume you would just leave the factory setup and the LS PCM would have the speedo tuned out but idk.

Sorry about my rambling lol.

 

My point, if you want it for availability of LS tuning, Great, What I am saying is wants and needs. Like I said, I see builds, cams in the 23x range all bolt ons and someone will say that they NEED 24x or it will not run properly with the LT pcm, these are people that have no clue of what they are talking about.

 

Key words referenced twice. "Person tuning it" LTx tuners are almost obsolete. Unless you are good enough to do it yourself.

You can count, on one hand, the number of "good" tuners in the country that will still mess with LT1 tuning. Granted, the tuning basics are the same, but 24x more time consuming. (irony).

All the diehard Opti guys ramble on. But why dump thousands of dollars into an engine or bolt-ons and not put a little more into a good ignition system and engine management.
$500+ for an MSD opti that may last a while. Then another. There ya go. 2 MSDs and there was your 24x. And don't forget the amount of work to install those Opti's.

As for finding parts, more and more parts cars are showing up in yards. LS truck with coils all over them, many many 96-7 F-bodies to get the timing cover. If I had a Puller for the hub, I could have had 5 or 6 timing covers. Maybe next weekend.

 

In all my years of daily driving and racing LT1s and myself putting something over 255k miles on my cars myself, not including the mileage on them when purchased I never had an opti fail.
The only one to give me grief was on a wagon I bought with 172k miles and it was a year or so after I bought it it needed a cap and rotor because it ran rough in wet weather.

If you are competent with a wrench and not turning 7000 all the time an opti should be no problem. And I have taken a completely stock opti to 7000, 6900 regularly.

Opti problems are usually neglect or incompetence.

Competent tuners are an email away, Tunercat and Datamaster with a cable is $250 and you can data log and upload tunes yourself after emailing the log to the tuner. It is slower than tune on the fly but don't pretend it is impossible.
Then again you will probably have to convince a tuner YOU are competent enough to give him good data before they will go this route.

 

$100 for the opti, $100 for the PCM, $130 for MSD coil+ICM, $130 for Scanmaster LT1, $100 for opti vacuum harness+spare ICM+stock coil+MSD coil wire, $100 for LT4 knock module (this thing sold within hours of posting, I feel like I could've got a lot more) $40 for opti wire harness+Lou's short stick

 

What's in the works?

 

I can't say. I was talking to him a few weeks ago. He's got an awesome plan and it'll work. It should drop the 24x swap down a few hundred $$$.
I'm sure he'll release the info in due time. It's a wonder no one else thought of this idea.

 

Whoa!

Easy, when we talked on the phone maybe I forgot to mention that this is a side project for a friend! Here are a few things I would like to clear up.

1. This would not be anything like the 24x Conversion that utilizes the coil on plug system.

2. I am merely integrating a cam signal into an Opti with a new reluctor and an aftermarket sensor. So that said friend can run on the express van system. This is NOT a 24x system and it is NOT as good as the 24x System.

3. I will NEVER Market this for these reasons.
A. It is Not even close to as Good as the EFI Connection 24x System
B. IF I were to market this it would not save anywhere near hundreds of $
C. I have no interest in re-inventing the wheel. Doing this for Fun for a Friend.



With that said, there are a few other things I want to put out there publicly.

1. I get calls all of the time from people in the LTx community wanting me to re-invent the EFI Connection 24x Kit. I have absolutely ZERO interest in doing this. Here are the reasons why.

A. I have entirely too much respect for Mike and the others at EFI Connection to do such a thing as steal their hard earned design. See below for further rant on this.

B. A second 24x Kit would not sell enough to justify such an animal. A lot of LTxers already gripe and complain about the price of most things that a second kit would have to be $100 to $200 for it to be considered priced right. Again, see below for further Rant.

C. EFI Connection's Kit is Amazing Quality, just like everything else they design and sell, and it is worth every penny that it is priced at. Rant Below.

Rant


I see it on the forums all the time, complaining about companies not putting out new products for the LTx community. There are two reasons for this, and there some members of the LTx community that are to blame for this.

1. The LTx was quickly replaced with the Gen III engines. This made everyone jump to the LSx

2. Some in the LTx community want new HIGH Quality parts for their Platform, but want to pay a cut rate price for said HIGH Quality parts. It doesn't work this way.

I recently built an EWP harness that came with a High Quality Sealed Relay and Sealed Fuse Kit that was Plug and Play with your EWP. Very Clean and Simple Install. Priced at $75.

When I started getting calls about the harness asking about price and I priced it to them, I would get a ton of belly aching about how they can build a relay harness for X dollars and how I was ripping everyone off. This is why companies don't go through the trouble of bringing new things to the LTx Community.

This is because you have make sure you can sell enough of what you are making to make up for the immense amount of R&D and support for what you are making. You also have to price it to take care of all that time that you spend making said item without getting paid to make it.

I cannot imagine the amount of time and effort that went into making the EFI Connection 24x Kit, and it urks me so bad when I see people Flaming Mike of Forums because they think his time and effort should be free.

Sometimes I come across the wrong way, and I'm not trying to **** anyone off. But these are some things that a lot of people just dont think about when buying items strictly by price, or when wondering why items are priced they way they are.

Hell, Bill, You sounded like this was a project for the masses.
I apologize, I was understanding it as an easier swap for those not wanting to go "all out".

Besides, Mike and his guys did great things. I cannot complain one bit about the system. The true opti guys can stay true. I don't fault them if their system works. But I want a dyno tune. Not emailing back and forth for days/weeks at a time. I am no tuning expert, so I leave it to the pros. I know enough to get myself in trouble.

But there's a reason why they system is there....technology.
