Dear Board Members,

We are thrilled to share a project we've been working on for over six months in collaboration with a renowned tuner and engineer trusted by many major brands. Our mission was to develop a simple, plug-and-play tuning device with Bluetooth app integration, designed to enhance your driving experience and provide adjustability that no other module offers at this price point.

Key Features of Our Tuning Module

-Simplified install: Minimum connections for a quicker install and removal

-Bluetooth App Integration: Connect via IOS or Android based devices at no extra cost.

-Multiple Maps on the Fly: Easily switch between different performance maps with a tap on your app.

-Simple Map Adjustments: Fine tune your maps and adjust the Boost ramping % and where you wish the increase of boost to start—choose between a more linear or aggressive boost increase. More features will be added over time.

-Return to Stock: Revert to stock settings directly through the app, without needing to access the engine bay or disconnect any connectors.

-GPS-Based 0-60 Timer: Measure performance improvements for each map with our integrated GPS-based 0-60 timer.

We Value Your Feedback!

We are considering adding light E85 maps and more aggressive octane options. Your input is invaluable to us—please share your thoughts and suggestions. Should we include these features, or is there anything else you believe would enhance our module?

We will have more details to follow but we thank you for your continued support and feedback!

Please focus on us poor 91octane, high altitude customers!
JB4 struggles with us on anything past Stg1.

Issue will be fairly similar since we are only adding boost on top of the factory target like the jb1. If the ecu for whatever reason does not like the amount of boost its running in your case lack of octane it will pull back keeping things extremely safe.

We can make small changes to the maps to allow you to try and push it as far as the stock ecu will allow but again the factory computer is going to have the last say..

If your goal is to make as much power as possible I would suggest a flash tune. This product was not made to compete with that or the advanced features of the JB4 Stage 2. Our product is more aligned with the JB4 Stage 1, JB+, Race Chip, and similar options. Our tuner is designed for customers seeking a warranty-friendly, simple plug-and-play device that works seamlessly with the factory ECU and its safeguards to boost horsepower and torque by 60+whp.

For the S58, our connections will be the manifold pressure sensor and the boost pressure sensor. Although the S58 TMAP sensor isn't as straightforward as in other models, our tuner is still essentially plug-and-play and as user-friendly as possible.

Regarding pricing, we are targeting a price point below $300, which we believe will make it very attractive.

Thanks! That is an attractive price!

Great move there, very tempting and by far the best priced tuning box right there 👏🏻 if I may ask, any particular reason to skip the Rail pressure sensor something like Dahler offers ? I feel with the higher boost even the rail pressure should be tapped in to keeping things in place but this is just my understanding and I still highly appreciate you’re offering something very decent at a price no tuner is offering so full marks there

That senor connector may need to be added for the m2 specifically when trying to go over a certain amount of boost we will find out more once we get into our M2 testing. On the m3 and m4 it hasn't been needed.

We are releasing this module for multiple engines S58, n55, s63,n63,n20/n26,b46/b48 so we definitely have our hands full. I just really wanted to give a little preview on what we were working on.

Did someone say E85? 👍

Whatever the stock fuel system allows.

This may seem a bit niche, but here in OR and WA we get 92 octane max, and all the tuning boxes or OTS maps for unlocked DME's are 91 or 93, would love to see one that offers whatever little bit more 92 octane can do for us here.

Here is an example of the maps we plan to release for the m3/m4.


Map 1: +3psi (91 Octane)

Map 1.5: +3.5psi (91-93 Octane)

Map 2: +4psi (93 Octane)

Map 2.5: +5psi (93-E30 Octane)

Hmmm. Wonder if the 1.5 map would work on Colorado 91oct @ ~6,800ft altitude. Was looking at Carbahn’s piggyback solution which is almost 3x the cost.

What’s your ETA on fully-dialed G87 maps? G87s run different boost stock (why JB4 has extra sensor on G87 vs G80)and are supposedly quite a bit different ECU map animals than G80/G82 cars, which is why Carbahn actually bought their own G87 to mess with. They take a scan/logs of YOUR ECU before building your piggyback map(s), tailored to your specific vehicle. I think they land on a more conservative tune, than say a JB4, too.

Due to all the changes needed I won't have an eta at this time. Like I stated above we are working on a bunch of models at the same time currently.

I see no reason to have a scan of a your factory ecu for an additive based mapping system though.
