Did you re-select and save your inverter?

Thanks
I didn’t re select the Prius as it came across when I updated the parameters from my saved 2.15A parameters.
The only thing that I could tell that didn’t come over was the BMW S box.

Can you please try a release that is older? like V2.22A or 2.20A It is possible a change I made for the testing Greg was doing in his VW Rabbit causes issues for your setup.

I installed 2.20A and sadly it still doesn't move.

If you flash it back to V2.15A you get drive again? Surprised it just refuses to work.

Your V2.20a log does not show Potnom or Torque, this stop it from driving.

Will need to work out what is different if it works on V2.15A makes it work again.

Sorry Tom, how do I flash it back to 2.15A?
I tried “updating” it to 2.15A and it remained on 2.20A

Okay, so I downloaded the 2.15A bin file as linked and upgraded the Zombie.

Unfortunately the file seems to be 2.20A on spot values even after numerous Zombie reboots and refreshes… is it possible to be the wrong file? 🤞

So back to 2.15A with the help of Hakan and his soldering/ ST link magic. The car is back up and running after loading up the previous parameters.

Keen to try whatever is required to progress the Prius 3 experience

There must be something on your setup causing problems. Damien utilizes a Gen 3 Prius on the bench for zombie release testing.

Not the best to just go at it if it means risking not being able to move the car though.

Thanks Tom and Damien.

I really would like to try 2.20A again and see if we can get the car rolling with all the great features.

I rewatched Damien’s video on 2.20A and also Greg’s latest one and think that maybe I could have the wrong dirmode setting 🤞

The Ghia isn’t a daily just an exciting rolling experiment so I am going for a 2.15A drive with logs and then upgrade to 2.20A 🙂

Well 2.20A software is loaded and I have uploaded my 2.15A parameters.

Changed;
Transmission to manual
Shunt type to Sbox
Dir mode to switch

Looks promising but car is not moving!

Change inverter and change it back again. Can you also please post your inverter serial number/part number

Changed the inverter from Prius 3 to none and back to Prius 3 and powered down/up the Zombie, unfortunately the car didn’t move.

Thanks

Did you provide an over view of your wiring? Just want to check its all been done right. Mainly interested in the grounds and 12V supplies and relays.

I don’t have a wiring diagram but I will take some detailed photos tomorrow to show the setup.
I slavishly followed Greg’s Rabbit wiring etc and because of having worked on quite a lot of VWs and Subarus I made sure that there is an abundance of grounds.

Is all the 12V to the inverter via that relay?

If the issues remains like it does need to confirm what inverter Greg has in his rabbit and what firmware was used as a base for testing on it (yes I did write it but its a while ago).
