Hello All.
What a great project speeduino is, and a big thanks to all who have gotten it this far.
I have a V0.4.4 (?) board that I have purchased from the store with the VR board. It is currently running the 2017.05 software. I have connected it to a Toyota 3L DOHC V6 (3VZ_FE) using the standard Plug (cut off the Toyota ECU). And all has been good to this stage. Except for Operator error.
I have 3d printed a new gear plate to bolt into the standard ECU box which and I have mounted speedy on to that.. It also has a Inovate LC2 connected up.
To this point I have found all the info I have needed to get it to Start and Run. Idle ->2000 RPM mapped. And I think it starts and runs better than factory.
A few Ooops along the way have been.
Now that I was happy It was getting close to road tests, but needed to sort the Idle as it would cut out when you took your foot off the gas. So I splashed out and bought the DRV8825 to control the stepper.
This is where I have hit the wall, and cannot find out enough info to fault find past this point.
With Speedy powered up ign on, car not running . will changing the idle values Move the stepper?
Is there a manual way to control the idle valve. ie move in or out with a button press (some where)
Some other test method that will help.
Cheers and thanks for your time, and efforts. I will attaché pictures etc when I get some more time.

A few Ooops along the way have been.
- When I first got it to start it was running rough and the RPM's where way off between tuner studio and the rev counter. Helps to set it to a single coil, not 3. helped a lot.
Next it would not rev past 3000rpm. this had me stumped or a while.... took about 3 days to sort. it was the Coil Dwell. once set to realistic values for a single coil. Zoom Zoom to 7000rmp. Oh Yea.
Now that I was happy It was getting close to road tests, but needed to sort the Idle as it would cut out when you took your foot off the gas. So I splashed out and bought the DRV8825 to control the stepper.
This is where I have hit the wall, and cannot find out enough info to fault find past this point.
- I have soldered the header pins onto the board. And using my digital magnifying glass (AKA phone camera) all looks good.
I have tested the connections from header pins to ECU pins all good there. (Once they where attached to the correct ECU pins. Ooops)
I have removed and cleaned the Stepper valve. Was a bit gunky. but moves free now.
Ive had it in the car. played with cranking and idle settings. ign on, cranking......... not moving.
I have enabled stepper open loop in tuner studio. 300 steps closed. 4 min steps. 4ms Steps. And DRV8825 current limit at full clock wise.
