Speeduino

Someone ever try build the Rev.A - 4 ignitions / 4 injectors ? Git page say "never tested".

My friend was build one piece and test on 2-stroke engine.

On SGU-ECU-1.0 there are 2 channels for O2 sensors. Does tuner studio and speeduino allow the use of two O2 senors? If so, would it adjust closed-loop fueling separately for each bank?

No, current firmware does not offer closed loop on the second O2 channel.
The channel can be seen and logged in TS.
This channel is available to any speedy version.

Good morning guys,

My board is up and running nicely in 4 cylinder full sequential. Now I would want to make use of all 8 injector and ignition channels. Did anyone change the firmware in this direction yet? To my understanding, this needs a good portion of modifications in the speeduino.ini and I didn't go through the complete .ino files yet.

best regards,
Frank

No hasn't been done as there is very little point to do it as yet.

A lot more other low hanging fruit worth going after before bothering with 8/8 IGN INJ.

Bug report, incorrect voltage. As the screenshot below shows, TS shows a system voltage of 21V, but the actual voltage is 14. 1V, but I'm sorry that I didn't keep the screenshot of the actual voltage, so I can't show it
I don't know if this BUG is caused by the board or the firmware. Hope to get help

Need to change in firmware probably or hardware voltage divider. I will check.

ryan_pajero-io, try to change R48 resistor to 6K34. Tomorrow I will test on my board.

I got some information from GITHUB and I thought I'd try to fix the code first
