There are actually only two different reluctors.
- 24x reluctor for single roller chain small-block Chevy and LT1
- 24x reluctor for double roller (or single roller) chain small-block Chevy ONLY

Hang loose and patience! It is in good hands with Mike working on the solution.
Thank you. This is going to happen, but R&D sometimes takes time...and this is taking time. We've put an incredible amount of time into this to come up with a very nice product. Hang tight, it's coming.

They were never for sale (never an option on the website for purchase), but we were talking with those who are interested in the conversion and getting a count for the first purchase quantity from the machine shop.

We won't sell these until we're satisfied with testing. Our 24x CNC reluctor "works", but it's not quite right. We'll get it right and likely very soon.

Hmmm, $250 and $275 respectively. Let's reread that headline again. "24x Reluctor _Pricing_ is Available" (my word emphasis). OK, my error for ***-uming that meant reluctor itself was actually available.

Yea, with the only two prices noted above, I knew that. I've just lost the ability to count.
Hang loose... hang tight.

its looking to be well over 1000$ by the time you buy the reluctor, sensor, cover, cam sensor, and harness, coils, ecu, ect...

at this point you may be better off to go after market or mega squirt.

i guess its still decent if you don't have the know how to do mega squirt..

Has anyone dealt with a fast??? electromotive??? megasquirt??? MicroTech?

I have and to be honest the LS1 PCM is far superior than anyone of them. None of them support a true coil per cylinder w/o any additional systems (Edis) to play with.

On top of that the LS1 PCM has a lot more resolution, the custom operating systems, coupled with the Road Runner, simply make the LS1 PCM the best system out there at the moment. You know how good it is to be able to control ACCURATELY an A/C System with a huge cam on a 350??? That is really tough with ANY aftermarket computer.

Last night we had a mustang that did 915rwhp with an SDS ECU... yeah it ran... But I wish you had seen a video of it... before it comes on to boost the car simply ROCKED like a mad horse.

Using the FAST on the LT1 you still have to use the optical unit. You are still prone to many of the "Failures" of it and you would still have to use add on systems to use the Coil per cylinder as I said above.

Many people say affordable??? I Have spent a LOT of money on trying to make the LT1 PCM run my car in a factory way with all I have in it. So far I have failed.

I deal with megasquirts on a daily basis... Its a nice cheap computer... but its nowhere near as powerful as the LS1 PCM.

i understand the benefits of the ls1 computer and i plan on running one in my car.. i don't however plan on buying a kit as i already had a custom wheel designed before hearing of efi connection, i will be trying it out shortly..

if it all fails then i will be spending some money as i already have 2 harness, computer, 2 sets of coils, efi live.

i plan on making a adapter harness that i can plug my lt1 harness into the ls1 computer.. i will scab the connectors out of a old lt1 computer i have laying around. it will have a add on harness for the coils and second knock sensor.

You will still need the cam sensor which eficonnection has readily available.

I've been holding off asking this question for a long time now,

What's the problem with the stock LT1 PCM? if your under a certain RPM? I have mine referencing boost with a 2 bar sensor and running great, total cost came to ~$30

As far as the Opti I was having repeated failures due to the rotor screws, so I dissassembeled a new one and re-applied new locktite to the screws (on every opti, one of the two rotor screws had minimal to no loctite from factory).

Not trying to start an argument I just dont see all the extra work and money for something that can be done much easier and cheaper?

You hit the nail right on the head... maybe for 570rwhp you have no issues. but when you start seeing a lot more boost and a lot more power, the better the resolution the better fueling you will have. Not only that... Ignition is MUCH stronger than our stock style system. You can have bigger gaps on spark plugs and you can have a smoother idle. NOt only that but air control for big cams is a huge concern for me. With the possibility of adding ETC to the system, honestly, you will be able to have a bigger cam that you could have ever dreamed of for street use and having nice street manners.

I mean... I wonder then.. why did gm went though all the trouble when all their research and development for this type of system AND was already payed? only thing needed for the LS1 car was to design the timing cover to fit another opti unit... They chose to do away with it... i wonder why... Maybe I think like you do, and it was a bad choice to design such a system when the one they had was cheaper, payed for and readily available. IN the end if they had made those decisions to keep the cheaper systems maybe they wouldn't be bankrupt? [/sarcasm]

No matter how you see it, put it, its a better system. If you choose to believe otherwise because its more expensive that is your way of justifying yourself not spending the money. IN fact, before this system I was going to do away with the whole setup and put in an lsx engine just to have a decent fuel injection system.

Even further I know that someone is modifying an LS pcm to be able to use low Z inj... think of the possiblities.
