Sorry, I meant could you let me know what your TPS puts out. My code is the same as yours, and neither Paul nor I can't access it at present, and I'd like to give the software what it needs such that I can get the controller going on the bench. Paul is sending the kit I need to reprogram the chip.

It's something like 0.5-4.5V...if you can't remember of the top of your head don't worry...I can wait until the stuff arrives from Paul.

My chip doesn't have a bootloader on so I can't program the chip...apparently, so Paul says, all Greek to me!! :-)

Cheers,

Adam

No worries, I'll do a bit of trialing around the 0.7V mark and see what happens.

BMW still going well?

I got the controller to stop showing the flashing LED (error) when I gave it 0.6V when I powered it up.

So it looks like 0.6V for zero throttle.

I haven't figured out what the maximum throttle setting is yet. Hopefully I'll be able to get access to the settings when the kit comes in the post from Paul.

Just wanted to record the 0.6V here should others need it one day.

I'm interested in doing this with my O-Revolt build. So keep the details coming, and Thanks!

Hi Mike,

The mod was supplied from JackBauer and is straight forward. I think I have attached details of the mod.

The board changes are pretty simple and I can supply photos of mine if you'd like.

Paul supplied my controller kit with the software that Jack used and I'm just trying to match the input up to the software. I'll get there and will post all info here.

Cheers,

Adam

I've had some success with finding the correct parameters for the hall effect throttle input on my controller...with help form Paul!!

"Anything below 0.5v should be an error, and 0.8v is considered zero throttle (anything below 0.8v and above 0.5v is zero throttle). And anything above 4.1v is full throttle, as long as it's less than 4.5v. So, I would set the pedal to 0.65v for zero throttle and 4.1v for full throttle." Thanks Paul!!

"Hi Paul,

I got connected to the controller and accessed the settings. They are attached. Could you have a look at the numbers and see if you agree with how I have converted bits to equivalent volts, please?

I’ve assumed that 5V is equivalent to 1023 bits so,

tminRC – 0164 bits is equivalent to 0.8V
tmaxRC – 0839 bits is equivalent to 4.1V
tfaultminRC – 0102 bits is equivalent to 0.5V
tfaultmaxRC – 0922 bits is equivalent to 4.5V

Does that make sense or am I way off?

Cheers,

Adam"

I forgot to mention that I have a dead zone programmed in that code if memory serves so the throttle needs a little tip before bringing on the power if that makes sense.

What, you just blip the throttle before moving off to wake it up?

Thanks for all the help with this JB!! I'll be up and running soon and hopefully Mora will follow suit with his Golf soon aswell!!
