I've got a SpeedyEFI NA6 PnP kit in my Miata.
First off, it's been over a year of use and I'm still very happy with what the Speeduino / SpeedyEFI brings to the table for the price.
It's not perfect, but it's constantly improving. For example, one of my biggest concerns last year was poor Accel Enrichment due to slow TPS/TPSdot readings.
The speeduino crew just fixed this issue in the 2022.02 firmware and I've been testing it with success! If I did it again I would stick with this ECU.
Anyways, I am looking for a wiring diagram or pinout for the SpeedyEFI Speeduino ecu. The tech support staff at SpeedyEFI have been helpful with specific wiring requests, but have not given me a wiring diagram as requested.
It would be ideal to have a pinout of the stock Miata ECU connector, as well as internal pins on the Arduino Mega and motherboard.
Trubokitty.com is for megasquirt, but the wiring diagrams should still be useful if you just need to quick reference some stock connector outputs. I find it easier to look at than the full wiring diagrams: https://trubokitty.com/#/ms3xassembly
If you can't get specific wiring diagram for the speedy it shouldn't be too difficult to map the miata connector to the arduino pins based on pin functions, which I'd imagine is somewhere in the speeduino wiki. A quick google search came up with this, but there might be a better page in there somewhere: https://wiki.speeduino.com/en/boards/V04
If you open up the case the board should have the version printed on it somewhere. You can then find the schematics and pinouts on github.
I have 2 of the speedyefi fishdogs. They have the ua4c boards. One is a version vc3 and the other is a vb2. All the info on those can be found on github. I assume whatever board you have is on there as well.
Very useful, thank you. I assume SpeedyEFI is using the standard Speeduino design then?

I'm going to have to crack it open again. I looked at my install pictures from last year and I didn't get a shot with the board revision.
Where do you look on github for the schematics and pinouts? Do I need a special program to open the files?
I did a search for image files and only found info for the very old board versions.
SpeedyEFI is not Speeduino. Speeduino is the open source project that started the Arduino controlling an engine thing. There are official/officially supported Speeduino board designs. The UA4C is official supported. To my knowledge nothing from SpeedyEFI is official supported. SpeedyEFI looks to have taken an open source project and profited off of it while contributing nothing and giving the whole project a bad name from their horrible customer service.
Well the fishdog from speedyefi is a ua4c board. I have 2 of them and have opened them up to set the jumpers. I can tell you for 100% fact what they are. They have printed on the boards what they are and are made by wmtronics. Again all that is printed on the board. I've taken a picture of the board showing that and posting it elsewhere on here. I looks like speedefi is sourcing the boards from wmtronics and doing their own case. I can only vouch for the fishdog though as thats what I have personally, cant say on their plug and plays.
