NexGenEFI News

Over the past few weeks, basically since the previous post there’s been a flurry of ideas, PCB design, code writin’ and other fun things.

I wanted to give Holley Users a heads up.  Instead of wiring up a CANBus & Power harness, we’ve taken the guess work out of it when it comes to hooking up your ECU to the NexLINK ECU Interface.  It connects directly to your Holley ECU and will provide Power, Ground, CAN Low and CAN High to the NexLINK and also has a extra CAN connection for other devices (laptop, Holley 3.5″ display etc).  Feel free to add it to the cart when purchasing a display.


Holley CANBus Harness


Pro Edition Race Column Mounts-
This custom piece from HG Manufacturing is crafted from 6061-T6 aluminum, featuring a black anodized finish for added durability. It is designed for individuals seeking not only a visually appealing digital dash but also a lightweight and strong option that aligns with their 5″ and 7″ Pro Edition mounts.  


NEW Products coming!


The NexCAST enables you to hook up multiple displays to the NexLINK.  That is just ONE of the features.  The idea here revolves around customizing a digital dashboard display to achieve a desired classic aesthetic, which may not be adequately accommodated by standard display sizes such as 5″, 7″, or 10″. By utilizing a combination of a 7″ display alongside a 5″ display, or another configuration, you can more effectively bring your digital dash concept to life. This flexibility allows for the creation of a tailored look that matches your vision.  The concept behind it is on the NexGenEFI Facebook page with a demo.  Software being written currently to utilize this functionality.



8 inputs resistance OR voltage individually configurable
2 EGT inputs
1 VR Speed input
1 Tachometer input

This option caters to two types of users: those with extra sensors they wish to display on the Pro Edition Digital Dash, and those using non-fuel-injected systems who want to utilize the Pro Edition Digital Dash.  NexNODE software will be in development in the next 2 weeks 🙂


NexGenEFI is expanding its offerings for Pro Edition users by introducing the NexLINK II, which includes all the features of the original NexLINK plus the addition of virtual switches. While the NexLINK II does increase the cost of the digital dash, it is equipped with a 600MHz processor alongside an ESP32. This setup not only enhances processing power but also supports Bluetooth Low Energy (BLE), Bluetooth (BT), GPS, OBD2, and additional functionalities planned for the future.  Picture below is of the PCB showing additional features.   PCB will be at NexGenEFI HQ in the next two weeks.


HONDATA and Pro Edition 10″ Available

ECU Support:

HONDATA support is good to go.  It is available as an option for the Pro Edition series.


Pro Edition Series:

The Pro Edition 10″ is available for purchase.  Currently the pictures on the Shop page are without a case.  That would be the preferred setup since a bezel can be created by Cory @ CarChains3D.com. The Pro Edition 10″ will also be available in a case.  I should have that picture up shortly.

Hondata, 10″ Pro Edition Digital Dash

Hondata code has been written and is out for testing.  You will need to set your CANBus speed to 500k when this is available for purchase.


10″ Pro Edition Digital Dash is just about done.  Wrapping up the layouts on the display and it will be ready to go.  I’m guessing mid-March latest.

Pro Edition, Haltech Elite 2500 ECU

Wanted to play with the Haltech Elite 2500 ECU again.  This time with more data.  Went to Chadata Tuning in San Antonio and was able to play with a bad ass VW Bug with a ez 30 (Subaru 3.0) swap running Haltech’s Elite 2500 Series ECU.  Very cool.  On the Pro Edition 7″ Digital Dash in the video its running the Carmoto layout.

So data wise I’m only converting to Freedom units on stuff like Coolant Temp and such.  The rest I’m displaying as pulled from the ECU.  Ie: the Elite 2500 series sends pressure data as kPa.  In an upcoming release there will be an option to select Freedom Units (PSI, *F etc) vs Metric (*C, kPa and so on).  Data like Lambda will remain as Lambda.

Always writin’ code!

Layout progress

Two new layouts have been added and two removed.  One is the “Race layout” and the second is called “Majestic”.  Please go to the Gallery to look at the photos to see all the current layouts included in a digital dash.  In progress is the Motorcycle layout. 
 *Race layout – this layout allows the end user to select 9 different data points to display on the race layout.

Locating dot has been added to each layout.  It is a GREEN DOT which notifies the user where the touch sensitive area is which enables said user to access the Configuration Screen.


Over the next few days, the website will be updated to reflect the functionality added to the NexGenEFI Digital Dash.

New Products

NexGenEFI goes beyond just offering a digital dash. Our aim is to deliver technology and data to your NexGenEFI digital dash swiftly, accurately, and with visual appeal.

Introducing NexNODE, the first expansion in the NexGenEFI Ecosystem. This device brings 8 additional inputs and 2 EGT sensor inputs to your digital dash. It communicates data efficiently via CANBus to the NexLink Pro ECU Interface, ensuring prompt and clear data display.

Currently the PCB is in testing.

EFI Source Gold Box EFI news

If you’re looking to pair the NexGenEFI Digital Dash with a Megasquirt3 based EFI setup, head over to EFI Source!

This is the same EFI setup I run in my turbo LS Camaro.  If you  need additional inputs to that EFI setup, speak with Mike and he can hook you up with what you need.  Not just the EFI setup but injectors, harness, additional input box etc.  While you’re there you can add the digital dash to it.

Progress Update: Sneak Peek of the Pro Edition Slim

The long hours are paying off.  Over the course of the past year spent long nights writing code, finding bugs, networking with aftermarket EFI manufacturers to come up with a product that is cost competitive in the market.

Here is a sneak peek at the NexGenEFI Pro Edition Slim digital dash.

Power is supplied from your vehicle at 12V along with Ground and various inputs to the ECU interface which is connected to the remote mount display via CAT5e cable.  The CAT5e cable supplies data and power to the display.

The PCB can be moved a distance away from the display.  NexGenEFI, LLC will supply a 3′ CAT5e cable but additional lengths will be available.

5″, 7″ and 10″ versions will be available along with something special that is being designed.  I would even go out on a limb and say this special thing is even better than the 10″ display.  

Stay tuned, there is still additional layouts to add which are already designed and cleaning up code for the current EFI systems which are supported.

On the to-do list is additional EFI systems to support and “Layout Packs” which can be added to the display.

Progress Update

ECU Support

Holley EFI has been added to the list.  Terminator X, Dominator, Terminator X Max.   Where RacePak protocol can be used, I am going to utilize that. 

Test data from a Terminator X from a running vehicle and non-running was taken to ensure accuracy. 

Haltech, Link and other ECUs are coming up next!

NexGenEFI Pro Edition Slim

Going to be moving to the printing phase.  PCB passed tests.  What this does is it enables me to have the smallest possible PCB, less heat, less power draw than the Ampseal version.

Its about the size of a credit card.

Thanks to our new Slim PCB design, we are empowered to create innovative products within the NexGenEFI Ecosystem, ensuring they are cost-competitive in the automotive industry.

Beta Testing Underway

Megasquirt, FuelTech, MaxxECU and ECUMaster are heading out for testing.  7″ and 10″ displays are being used in this effort.  Feedback will be prioritized in a Must-have, Should-have and Would-like to have categories and will be worked accordingly.

Release Date

December 1st is the release date for the Pro Edition Slim Series.  The Ampseal version will be phased out.  Please follow the Facebook page for a demo of the Slim Series to see why its the product to go forward with.

Custom Dash Bezels

NexGenEFI, LLC can also design and produce professionally crafted custom dash bezels for your vehicle.  

Progress Update

Pro Edition Series

The 7″ and 10″ Pro Edition displays are going to undergo testing by a select few Beta Testers.

These Pro Edition setups have an Ampseal connector along with a harness which will support inputs from CANBus ECUs and Serial ECUs, blinkers, headlights, TPMS, Bluetooth GPS and fuel level sending units and a super bright 16 LED light bar which can be configured by NexGenEFI for your needs.  Case is a made in ABS for durability and UV resistance.

Pro Edition Slim Series

5″, 7″, 10″ display solutions! Another custom PCB has been designed and is undergoing testing.  This PCB was designed to enable the End User to remote mount their display a few feet from the custom PCB in a low-profile ABS case.  The Slim Series is ONLY for CANBus enabled ECUs and has the same inputs and LED light bar as the Pro Edition series.

Super secret project coming up!
There is one solution that is fixing to get started as soon as testing on the Slim Series PCB is complete.  No beans shall be spilled early on this one! 😉

NexGenEFI, LLC proudly supports all EFI manufacturers and will at no charge write code to support additional ECUs with purchase of a display.  If you are an EFI manufacturer and would like to carry our products with your system, please email us.
