This sounds great, and I’m willing!
So... Ok... how do I purchase this???

Ive sent you a PM

@Nickz, What type of plastic have you used to print the cases. And how dust/water/moisture proof are the finished units. The plugs you are using are up to the task.
I'm looking at a BARRA 6 conversion (wasted spark and paired injectors). And the loom is quite short, and ECU would need to reside under the bonnet with out extending the loom.
I'm going to remove the VVT as speedy cannot handle it. either lock the original units or put in adjustable after market ones.

Not for engine bay install. The cases are really to protect it from physical damage. I have found metal boxes for the smaller version boards, but not this one yet.

In your post #32980 on page 11 you outlined the feature updates of the new board design that it now has 8 injector and ignition channels. Does the firmware support all 8 channels so that a V8 can be run with out using batch fire injection and waste spark with this board?

I've been looking into various Speeduino boards for a vehicle I'm building and your recent design has really peaked my interest. Is the pricing you listed in your post outlining the board improvements still correct ?

All my boards run current Speeduino firmware, These where created to someday hopefully be able to run the full sequential as the Teensy should be capable of doing so when fully supported, Teensy does run great on current firmware (I believe its smoother and more responsive over using a Mega2560).
The current Speeduino officially runs 4 cylinder sequential.
It is possible to use a total of 9 channels with modified firmware, so for example a 6 cylinder, 6 coils and 3 paired injectors, 6 injectors and wasted spark coils, a V8 would not be possible.
currently i run a V8 with 4 sets of paired injectors and 8 coils in wasted spark configuration and so far have not seen any benefit to go sequential.

My pricing for a completed assembled board as priced is still current as i have plenty of stock.

I am working on another platform that will be a direct plug in on these boards.

We've been running the Teensy 8x8 for 4 or 5 months now in a B20 Honda Prelude Si.

Been running totally mint, except for a random misfire at 4000ish RPMS on the 2019.05 firmware. It seems like that was pretty common on that firmware? No matter what we do we can't clean it up.

Nick, are we still using your Github as the main source for Firmware updates for the Teensy? Last I heard, the Teensy wasnt supported with the standard releases.

Has that changed? Would be cool if your board was integrated into future standard forks of Speeduino. I'd like to try to get my 8x8 updated to see if the misfire goes away.

I'm going to keep scouring for an answer, I haven't stayed up to date on the project since we got the Prelude running great.

You make a great board though, Nick.

No problem, Just doing the update right now to the latest september firmware.
I have put in for PR for my pin map but seems to be ignored. :cry:
