Frequently Asked Questions
Straight answers about our work, process, and products.
General Questions
Do you only work on BMWs?
Nope. BMWs are a big part of what we do, but we work on plenty of other cars — Mercedes, VW, Porsche, and classic American stuff included.
What kind of projects do you like best?
Mechanical problem-solving. Swaps, electrical issues, half-finished builds, and cars that other shops don't want to touch.
Do you take on unfinished or abandoned projects?
Yes — as long as expectations are realistic. We'll assess what's there, what's missing, and what it'll take to get it running properly.
Can you fix work done by another shop?
We do it all the time. That said, correcting someone else's mistakes often takes longer than starting fresh. We'll be upfront about that.
Do you work on daily drivers?
Yes, but we specialize more in enthusiast and project cars. If your daily has a weird issue that keeps coming back, we can usually help.
Services & Technical
Do you do full engine swaps?
Yes. From mechanical fitment to wiring, ECU setup, cooling, and driveline work. We aim to make swaps feel factory-finished.
Do you tune ECUs?
We handle setup, configuration, and integration. For custom dyno tuning, we outsource that to a trusted tuner.
Do you install customer-supplied parts?
Yes, but we'll inspect them first. If a part isn't compatible or is low quality, we'll say so before it causes problems.
Do you fabricate parts in-house?
Light fabrication, brackets, mounts, and problem-solving pieces — yes. We also make several products in-house for sale.
Can you help plan a build?
Absolutely. If you're in the planning stage, we can help you avoid costly mistakes before parts start piling up.
MAFsync
Questions about our AFM translator device for classic engines
What is MAFsync?
MAFsync is an aftermarket airflow meter translator device. It sits between a modern hot-wire MAF sensor and your factory ECU, precisely translating the modern sensor's signal into the exact voltage curve your ECU expects. The result is a clean, stable idle, improved throttle response, and proper fueling — all without touching the ECU or reflashing anything.
Why would I need this?
Original mechanical vane-type airflow meters (AFMs) are bulky, restrictive, and increasingly hard to find. Even working original units can eventually develop track wear and dead spots. MAFsync lets you replace that older technology with a modern, reliable hot-wire MAF sensor to future-proof your engine.
Does it modify or reflash my ECU?
No. MAFsync works inline — it plugs directly in between the sensor and the ECU. The factory ECU itself is never touched, modified, or reflashed. This makes the upgrade fully reversible: unplug it, reinstall your original AFM, and the car is entirely back to stock.
Will it throw codes or cause a check engine light?
No — because MAFsync translates the signal perfectly, the ECU sees exactly what it expects to see. There are no additional codes introduced by MAFsync itself. If codes are present after installation, they are likely pre-existing engine faults.
Do I still need a tune after installing MAFsync?
No. Each unit is pre-loaded and locked with a calibration profile specific to your exact engine and ECU combination before it ships. You do not need a dyno tune, ECU reflash, or any calibration adjustments on your end. It is truly plug-and-play.
Which engines does it support right now?
Current confirmed support includes: BMW M20B25, M42, and M43. M30B35 support is in active development. Additional platforms including Toyota, Mazda, Nissan, Opel, and Alfa Romeo are planned — see the MAFsync product page to join the waitlist for your specific platform.
What MAF sensor does it use?
A specific Bosch-style hot-wire MAF sensor is included with every kit. The module is calibrated precisely for the flow characteristics of this exact sensor. Using a different sensor than what is supplied will affect calibration accuracy and is not recommended.
Is this street legal?
As with most aftermarket engine management modifications (such as popular MAF conversions for Porsche and other classic platforms), emissions compliance depends entirely on your local and provincial/state laws. MAFsync is designed as an aftermarket performance part and has not been CARB-certified or submitted for federal emissions testing. It is the buyer's responsibility to verify legality and ensure compliance with their local regulations before installation.
How long does it take to ship?
Orders placed during our initial production runs will ship approximately 4–6 weeks after the batch order closes, plus transit time. Every single unit is hand-built, bench-tested, and verified before it leaves our shop.
My engine isn't on the list — can you build one for it?
Possibly! If your ECU uses a similar vane AFM signal architecture, it may be supportable. Reach out with your engine and ECU details before ordering and we'll let you know if it's possible. If it's not currently supported, we'll add your platform to our development list.
Getting Started
How do I start a project with you?
Send us a message with details about your car, goals, and current condition. Photos help a lot.
Do you provide estimates?
Yes — realistic ones. Custom work can change as we dig in, but we'll always communicate before moving forward.
Do you require a deposit?
For larger projects, yes. This secures shop time and parts ordering.
Can I check in on my build?
Of course. We keep communication open and are happy to give updates as work progresses.
What if I don't know exactly what I want?
That's fine. Part of our job is helping you figure out the best path based on budget, goals, and how you want to use the car.
Still Have Questions?
Every build is different. Reach out and let's talk through yours.
