There are a few other open source ecu's floating around too. I know there are a few members on here working on rusefi.

 

OK, the beta run is now in production! Just a small run of 10 units for those willing to do some testing and, I would recommend, have played with something like Megasquirt before.
Price will be $150USD plus shipping for something that looks roughly like this (Although with a black enclosure):


The production units price will be a little higher, but not a lot.
Production is likely to take 3-4 weeks, after which time I'll post back if anyone is interested.

The documentation is still a bit sparse, but I'm working through it over the next few weeks if anyone wants a read: https://speeduino.com/Speeduino_mx5.pdf
(Or alternatively the wiki version: https://speeduino.com/wiki/index.php/MX5_PNP)

Ohhh and the launch control input is working now too, as suspected I did have to disconnect the neutral switch.

 

I am interested in buying a test unit. x)

What is the connector you are using for tuning? looks like a printer cable. hopefully that means a more secure connection over a db9. (and by secure i mean not falling out while driving.

 

You mean the USB one for connecting to a laptop? It's just standard USB-B, same as you get on many different peripherals (Printers included).

 

Just different from the mega squirt and hydra ecus which are the only two i have used. I will probably prefer a usb-b anyway.

Will an order page be on the website for the beta runs soon?

 

noisymime, you have a pm

 

Has the beta production run been finished or is it close? Any updates?

 

The boards arrived last Friday and I'm just doing some quick testing before finalising orders for them

Assuming there's no issues, I'll do a much larger batch within a few months. Everything has been running great on my car for a while now though, so hopefully there shouldn't be any major issues.

Not very exciting, but I finished up all the faceplates the other day

 

I'm interested, are the beta slots filled?

 

Still interested here as well. Money is ready to go!

 

I'm just finalising things at the moment and prodding people who had mentioned they were interested previously to make sure they're actually going to pay. I'll post back in about a week, but there will be a few available.

 

Hardware all set and ready to go. I'll be making the final firmware changes over the next day or so and then will be contacting those who have expressed interest.



Assuming all goes well in the beta testing, a larger run will be coming in around 2 months.

 

I'm interested in buying one! This looks great!

I like your documentation so far. Its a simple thing, but it shows your attention to detail and understanding of the end-user. It makes me think the rest of it will be that way too. In the absence of any other evidence so far. I'm still willing to be an early adopter, though.

Reading this thread from the beginning, I didn't guess that you'd make them for the rest of us. Thanks.

 

Any updates?

 

Ok, I've replied to all those that have expressed interest now with the details.

I have 1 unit left from someone who decided not to order until the production units are ready, so if there's anyone else interested just shoot me a PM

 

Ohhh and as an update on the actual units, the first of these went out last week and 1 user is up and running already!

 

Ordered and paid.

 

I am also interested in early adoption or purchasing one outright, I like the arduino over the MegaSquirt

 

Just a quick update. Everything seems to have gone fairly well with the initial beta run. I believe most people are now up and running (at least out of those that have tested it)

I've decided to do a second beta run though, just to improve a few things here and there. The differences are:

• Fuel pump circuit has been changed and now uses a beefed up smart FET. The circuit in the Beta 1 units works fine, but the polyfuse I had added to try and prevent damage if someone forgets to remove the ST_SIG fuse hasn't worked as intended. This change should mean that the circuit remains protected in that instance
• A dedicated fan control circuit has been added
• Cuttable traces added to allow conversion to sequential fuel for anyone who wants to run the wires

These have been sent off this week for production, meaning they're probably about 3 weeks away. It'll be another run of 10, but assuming no issues I will begin a much larger production run shortly after that.
If anyone is interested in one of these, shoot me a PM and I'll reserve one for you. Price will be $180USD + postage
(I've decided the final retail price will be $200USD, so the beta runs are slightly cheaper than this)

 

Cool stuff, nice to see this isn't dead.
Have you had any issues with the speed limit of 16Mhz?
Thought of going ARM?
