Black Knight Diesel Performance and Repair

07/14/2026

🚨 **ATTENTION LLY DURAMAX OWNERS!** 🚨

This is the upgrade we've all been waiting for.

For years, LLY owners have had to rely on **used or rebuilt FICMs** because Bosch discontinued the original units. Unfortunately, rebuilt modules can be hit or miss, and many of the original electronic components are no longer available.

🔥 **Not anymore.**

We're excited to announce that **Black Knight Diesel Performance & Repair** is now offering **City Diesel's ALL-NEW LLY FICM!**

✅ **100% BRAND NEW** — NOT rebuilt
✅ Completely redesigned from the ground up
✅ Updated, modern electronic components
✅ Plug-and-play installation
✅ Built in the USA
✅ Designed for OEM-level reliability and long service life

Because these modules are so critical to proper engine operation, **City Diesel only sells them through select repair facilities that follow the proper diagnostic procedures.** Replacing a FICM without correctly diagnosing the root cause can lead to unnecessary repairs, which is why proper testing always comes first.

At **Black Knight Diesel**, we don't guess—we diagnose.

If your LLY is experiencing:
🔹 Hard starts
🔹 Intermittent no-starts
🔹 Injector driver codes
🔹 Random injector circuit issues
🔹 Or you're simply looking to future-proof your truck...

Give us a call.

💪 If you love your LLY and want to keep it running like the **Energizer Bunny**, let us install the industry's newest and most reliable FICM solution.

We are making some changes for the good!

I have been basically a 1-3 man show for many years. It has always been me and my two to 3 techs. I basically have several roles in this business including fixing vehicles, service manager, service writer etc etc. Every role a repair shop has, I have been it.

That is about to change. I have missed so many calls being out with the techs, chasing parts troubleshooting and dealing with customers.

Although we have outstanding customer service, I feel we are lacking in a few things. That is changing!

I just hired office personnel to help deal with a lot of this so I can be out in the shop to grow my techs as well as grow the business.

This is going to enable me to implement something I have been wanting to do for awhile. We did a trial run of it a few months ago and it was working. It’s a learning curve forsure.

This will also allow me to add additional services to the shop as well.

Look for more Tik Toks and Facebook posts in the near future.

Thanks
Black Knight Diesel.

Due to the power outage. We closed early. With no air flow through the shop. It is miserable.

OGE should have power restored by tonite. 3 power poles across the street from us are down. There is a crew working on that right now.

We should be back open July 7th if power is restored.

07/06/2026

We are currently out of power due to the storms that came through July 4th. Hopefully OGE can restore power so we move forward.

Luckily, our phones are cell based. We can still receive calls and texts.

Sorry for this inconvenience.

WE'RE HIRING!

We're looking for an Entry-Level Diesel Technician who's ready to build a career—not just find another job.

The biggest things we're looking for are:

A great attitude
Strong work ethic
Willingness to learn
Dependability

Basic hand tools are preferred, but they're not a deal breaker for the right person.

As the owner of Black Knight Diesel, I've been in this industry for over 20 years. The truth is, I didn't know anything about diesel when I got my first opportunity. A dealership took a chance on me, and it changed my life.

I know what it's like to start at the bottom. That's why I'm willing to invest in someone who wants to learn.

Training someone takes patience. From a business standpoint, it costs time and money. You're going to make mistakes—we all did. The difference is having experienced technicians who are willing to teach you, explain why something happened, and help you become a skilled technician instead of just throwing you to the wolves.

If you show up every day, work hard, ask questions, and want to improve, we'll do everything we can to help you succeed.

Here's what you'll get:
✔ Train under experienced technicians
✔ Paid holidays
✔ Paid vacation after one year
✔ Sick pay
✔ Hourly pay (not flat rate)
✔ Plenty of work—no fighting for hours
✔ Monday-Friday, 8:00 AM-4:00 PM
✔ Overtime available if you want it
✔ Paid ASE Certifications after two years of employment

You'll gain experience in:

Preventative maintenance
HVAC repairs
Brake systems
Fuel injectors
Engine replacements
Transmission replacements
Performance builds
In-house dyno tuning

If you're looking for a shop that will actually invest in your future, I'd like to meet you.

I'm conducting interviews this week and next week.

Send us a message, stop by the shop with your resume, or email your information. Let's talk about building a career in the diesel industry.

We've had some challenging cases recently.

One customer brought in a 2016 Ford F250 with intermittent remote start and TPMS issues. Another shop claimed they replaced the RKT module, which turned out to be a lie. We found and replaced the module, but the problem persisted. The RKT module then threw an "Antenna 2 missing" error. We searched everywhere for the missing antenna, found one on eBay, installed it in the headliner... and the problem remained! It was so frustrating. We kept digging and found a forum post about the exact same issue. The customer had a wireless trailer camera installed in the cab that was interfering with the remote start and TPMS. We unplugged it, and everything worked perfectly again.

Next up: a 2021 Cab and Chassis Ram Wrecker. The previous owner had the truck deleted, and after that, the PTO stopped working, so they bypassed it with a toggle switch. This caused the transmission to burn up, and another wrecker company bought it. Fast forward to now, and I got it. The first thing I did was flash the correct tune to enable PTO functions and removed the bypass switch. The PTO now functions correctly with the factory switch. The PTO performance code disappeared, and the transmission no longer goes into limp mode.

In PTO mode, the transmission locks the torque converter. The transmission doesn't know it's in PTO mode if it's bypassed.

We understand that these kinds of problems aren't always profitable for the shop. Sometimes you get stuck in a loop, wasting time. We don't like working for free, but the most rewarding thing is fixing something that no one else can. We pride ourselves on thoroughly investigating issues, finding the root cause, and fixing it.

We do brake jobs, front ends, and turbos, which are our bread and butter, but we also tackle electrical and drivability problems that other shops avoid. Not us – we will find the issue and fix it.

Give us a call!
