ECU Support update

ECU Testing progress

Had some fun today.  Headed down to see Chad Berryhill over at Chadata Tuning who has been extremely helpful with his wide array of knowledge for many aftermarket ECUs.

Today I tested (for the last time) Holley code.  I had made updates to pull as much info from the CAN stream and wanted to ensure 100% compatibility.   Took out my beater display which has seen its fair share of bumps.  Its based on the old case design which I personally like.  It is available so I’ll add it to the website just in case someone else wants that same design.

Anyway, today’s test was with the Holley Term X TBI rig on a SBC, naturally aspirated.

Here ya go!

Haltech ECU test

The next test was with the Haltech Elite 2500 series.  I have all of the code written but need to make minor changes.  So this video was to test connectivity, data transfer speed and just read RPM. 

Worked perfect.  I’ll update the rest of the code and ensure data points are available in the Configuration Screen.

Here ya go!


Online Sales
Sales are back open.  I have 2 3D printers running, printing cases for the new design.


ECU Support
Haltech code is written and ready for testing.  I’ll get that tested this week.

Link ECU code is being written, so it is coming also! 🙂

New Case designs coming!

New Case!

While I thought the smaller 5″ square type case was “ok” and the 7″ case also, there was room for a more modern look.

Well here ya go!  All printed in ABS for durability.  Being that its new, I am behind printing cases.  I will have it on the website I believe Sunday (12/10/2023) but there may be a 1-2 day delay in shipping while I get caught up printing cases. 


Final PCB

Received the new v1.3 PCB, fresh off the press!  

30% smaller, surface mount GPS, internal improvements.

Played around with the GPS, it works, pulls down 10hz updates.  I’ll play around with it some more.


Working with both of my graphics designers to optimize layouts and also create new layouts.  I should have some sort of progress report on that at least by this Sunday.

Beta Testers

FuelTech – not concerned.  Doing a final test but I ran that code 3x already. LOL.  Just want to be sure.

  1. Megasquirt- I run the EFI Source Gold Box, it works.  Tested against my Camaro.
  2. Speeduino Serial/CAN- Serial works.  CAN also I believe.
  3. MaxxECU- Already tested internally.
  4. ECUMaster – Already tested internally.
  5. OBD2 – Already tested internally.

What that means is I am sending out Pro Edition 7″ and 10″ displays to select Beta Testers that way they can hook it up to their vehicle, report back on what they like, dont like and so on.  I’ll tackle suggestions in 3 Categories: Must Have, Should Have and Would Like.  Must Haves will be knocked out, Should Have depends on level of effort and Would Like goes into the Backlog/prioritized to be worked incrementally.

Additional EFI Systems

Holley is coming up.  There are also more, I just need to look thru my list and prioritize.

If you are an EFI manufacturer and would like me to support your EFI system, please get in contact with me.

Release Date

I am looking at a December 1, 2023 release date.  I’ll have special Christmas pricing for the 7″ and 10″ Pro Edition displays.

v1.2 PCB (L) and v1.3 PCB (R)

Pro Edition – for Beta Testers

This is a sneak peek for the Pro Edition which will be mailed to Beta Testers.  The orange case is just internal use for myself.  They’ll be getting black cases.  So far I have the following EFI systems covered for testing:

  • FuelTech
  • MegaSquirt3
  • Speeduino CAN/Serial
  • OBD2

I believe I have a tester for MaxxECU and ECUMASTER but need to confirm.


LED Board

Its here!  The cool thing is, I’ll work with the End User on what they want it to do.  IE: Specific LEDs for Shift (like middle 4 or something) then the outer ones for other things they want configured.

This board goes on the inside of the case and is visible through the upper slot.



About two weeks have passed since the previous update.  There has been ALOT of progress.

  • Overall approach on how to optimize data processing while using both cores of the CPU has been implemented
  • BLE TPMS sensors are supported, code has been tested
  • Internal code to speed up gauge refresh has been completed
  • New PCB has arrived, has been tested
  • Warning lights for code has been implemented and tested
  • Configuration screen has been updated but needs more settings added
  • Layouts have been updated for additional features

PRO EDITION – Beta Testers –

I have (4) four Beta Testers which will test the Pro Edition. Two 7″ and two 10″ models will be going out.  These beta versions will have a limited amount of layouts since they are still being designed.  Their goal is to test usability, performance, overall physical appearance, documentation, ease of use and so on.

The following ECUs will be tested by the Beta Testers:

  • FuelTech
  • MegaSquirt
  • Speeduino CAN/Serial
  • OBD2

I believe I have another tester for MaxxECU and ECUMASTER.

Upcoming Development

  • LED Board should be here in the next 2-3 days.  This is the configurable shift light
  • Build Pro Edition beta units to mail out to Beta Testers
  • Update 10″ display layouts to match the 7″
  • Test inputs for blinkers, fuel sending unit, high beams

NexGenEFI PiDash

Due to constant nagging (just kidding), popular request I guess I’ll update the PiDash.  I’m going to try to move everything from the old site (the wiki page) to this site.

This is the free image I’ve been making available which runs on the Raspberry Pi 4 but since I hadnt updated it in quite a long time, some Raspberry Pi 4 boards had issues booting it.

Current status:

  • Linux image has been updated
  • Boots up, runs TunerStudio and my NexGenEFI PiDash configurator app works
  • VNC has been added and will enable you to remotely connect to it to tune instead of using a small display.  You will still be able to use the display directly with a keyboard and mouse if you want.

What needs to be done:

  • All of the customization to the Linux image, so thats on the to-do list. 

I’ll work on this as time allows.  The Pro Edition dash has priority.



How I track the work for the Pro Edition.

Alot has been going on behind the scenes.  I have 3 layouts created with another 3-4 on the way.  I need to make sure I can fit all of those on the Nextion itself.

The layouts are almost fully functional with small things like blinkers, warning lights and so on which need code written to support them.

TPMS BLE sensor code took me a few hours to write.  I can support two or four sensors which will be available as an add-on.

Still alot more code needs to be written and I’m testing as I go along.


New PCB has been created.  As I go thru writing code there are things that either myself or my PCB designer add / remove / improve.

Added was an accelerometer that way I can write code so you can test your 1/4 mile ET on street.

We’re going to add a SMT GPS but not this initial version.  For now I’m going to use the GPS that I’ve been writing code for.

The LED Shift light board is also being printed.  You’ll be able to configure the colors, sweep (L-R, In-Out etc).

These PCB runs are going to go out to beta testers.

So far a ton of good progress and minor road bumps but going really well!


Looks like a bug was found in the CANBus side.  I fixed it and released an update to the code.  Also added an additional check if the ESP32 and the Nextion cannot communicate, the BLUE LED will blink on the ESP32.  Its avail on the Community Edition link.

Progress Update

Community Edition: Pretty soon I’m going to have a very small update.  What that will do is check to see if the ESP32 can communicate with the Nextion 7″ display.  If it cannot, the BLUE LED will flash on the ESP32 until connectivity is established.

Pro Edition:
All of my development is happening on an esp32 on a breakout board. I should have some connectors here today and will move my dev code to the custom PCB. Once I get a few layouts done I’m going to be looking to send a few units out to Beta Testers. Beta Testers can get it with a case or without, up to you. But remember, how you mount it without a case is up to you. Please ensure you do not short circuit anything etc.

Pro Edition layouts: Here’s 3 that are in progress.  The first is the “Futuristic” layout which is currently being configured.  The next two are more retro layouts but I have not chosen which will be in the Pro Edition yet.

Progress update

Layout design is in progress for the Pro Edition. I’m looking to have some sort of demo of this layout. I have a new graphics guy in training so I’m getting him up to speed.

7″ and 10″ Display pictured with a in-progress layout design.  The layout in the image is the actual screenshot from the layout editor.  Layout may change slightly.
