7 Things We’ve Been Working on Before Shipping the CISON LS-52 V8

Just wanted to share a quick update with everyone about the CISON LS-V8 engine project.

The first batch of LS-V8 engines is now fully prepared, and over the past few weeks we’ve been spending a lot of time at the factory checking engine conditions again and again — startup testing, RPM stability, packaging inspection, manual updates, and a lot of small detail adjustments.

For us, this project has never been about simply shipping out another model engine.

We really want customers to receive a realistic V8 engine model that feels refined, stable, and genuinely enjoyable to run on the desk.

Because of that, we decided to spend more time testing and refining things before shipment instead of rushing everything out early.

That’s also why shipping got delayed a little recently.

We really appreciate everyone’s patience and support during this process.

1. LS-V8 Shipping Update

Right now the factory is still doing final random inspections, and if everything looks good, shipments should start going out later this week.

We’ve been repeatedly checking:

• Startup testing
• RPM stability
• Packaging inspection
• Manual updates
• Accessory verification
• General running condition

To make sure you receive an LS-V8 that actually feels worth the wait, we chose to spend more time refining details before shipment.

2. QC & Packaging Upgrades

For the LS-V8 project, we also upgraded several parts of our QC (Quality Control) and shipping process.

• Each engine now comes with its own unique tracking code
• The factory keeps archived shipment photos for every engine
• The internal packaging structure has been upgraded
• The instruction manual now includes more FAQ content
• The entire shipping traceability process has been improved

So if there’s ever an issue later — like missing parts, shipping damage, or other after-sales concerns — we can trace the exact engine much faster and help solve problems more efficiently.

3. Ignition System & Accessories

A lot of people have been asking questions about the ignition system and accessories shown in the recent videos, so we wanted to explain things a little more clearly.

The servo bracket is already available. The servo itself is not included and will need to be prepared separately by the user, although we may also offer it individually later on.

The integrated display dashboard allows users to program their own RPM settings, including minimum and maximum RPM limits.

Many people also asked about the “large ignition coil” and “small ignition coil” shown in the photo below. “large ignition coil” is installed in the engine already. the smaller one is held by hand. you can pick one at your preference.

The larger ignition coil setup belongs to the High Output version. This version delivers stronger ignition energy and is designed more toward performance-oriented running and higher RPM stability.

The smaller ignition coil setup belongs to the Compact version. It offers a cleaner and more compact layout with reduced space usage.

As for Coil-on-Plug ignition, the easiest way to understand it is: Each cylinder has its own independent ignition structure, which helps deliver more direct and stable ignition response overall.

4. MCU Performance & American V8 Sound

From the recent testing videos, you can probably already hear that the MCU ignition system is running very smoothly.

The MCU is basically the small control system responsible for ignition timing and RPM logic. RPM climbs feel smooth, and ignition response stays stable even at higher speeds.

Some people also noticed the “rev limiter” style sound in the videos.

That’s not a problem or malfunction.

It’s actually the programmed RPM protection logic kicking in.

Once the engine reaches the preset RPM limit, the MCU begins adjusting ignition timing rhythmically, creating that limiter-style mechanical sound.

Even though the LS-V8 is still a V8 model engine, we spent a lot of time tuning the running rhythm, sound feedback, and overall mechanical feel to capture some of that classic American LS V8 character.

Especially at higher RPM, you can hear a very noticeable American V8-style sound signature.

That deep mechanical rhythm has become one of the favorite parts for many engine model enthusiasts so far.

5. Transmission Project Update

We’ve also seen a lot of questions recently about the transmission project.

Right now the transmission system is still under development and testing, and it’s currently expected to launch around July.

Since early production quantities will probably be limited, we’ll also open an early subscription option later for customers who want to reserve a spot ahead of time.

More transmission testing footage and realistic engine drivetrain updates will be shared as development continues.

6. A Small Surprise for First Batch Customers

For the first shipment batch, we also prepared a few small commemorative gifts for customers supporting the LS-V8 project from the beginning.

And on top of that, 3 random VIP customers will receive an extra Lucky Gift.

These gifts are packed randomly into shipments, so honestly, even we won’t know which boxes contain them before delivery.

The surprise will only be discovered once the package is opened.

7. More Content Coming Soon

We’ll continue sharing more real testing content very soon, including:

• LS-V8 startup videos
• Cold start testing
• High RPM testing
• Factory tuning footage
• Packaging & QC process videos

Some details honestly don’t fully come across on camera.

But once the engine is actually running in front of you on a desk, the combination of the moving mechanical parts, realistic ignition response, and American V8-style sound feels even better in person.
