It's conceivable that signal lead is meant to tickle a watchdog timer and his approach of giving it a heartbeat with a 555 timer chip is legit.

comments?

sorry but from the haste in the previous post, I wrote in Italian, I corrected the post
I bought another identical one. When it arrives I do the tests. I have 5 electric cars so even though I have 2 I use them. With the other identical one I can understand better, my main doubt is that this one I have is defective. I'll know this when I try the new one that's coming. There is a possibility that my ibooster needs a can bus command to go into fail safe mode.

yes it is legit. but I don't understand why alexbeatle in the video works with the wire always connected.

I mounted it. With the NE555 it works. I put the Ford Transit master cylinder with a 25.4 mm piston, the original one has a different orientation and a 23 mm piston. So while I had to change it, I chose the one with the bigger piston. My car had a 20mm. So I have a shorter pedal stroke, but harder, but the ibooster has 2 or 3 times the force, compared to the original depression. So now the pedal is soft and it brakes well and by sinking a little it brakes decisively and pushing a little more, it nails hard. Now it has beautiful braking. I am delighted and it exceeded my expectations. I have to thank EVcreate for the schematic and the photos.

The other ibooster identical to mine has arrived, the one that mounts the renault captur hybrid. I connected it and it does the same thing as the one I mounted in the car. So it's neither faulty nor defective, but it has a different factory setting. I read the ibooster documentation and it says that it can be configured by the manufacturers for the various types of car. now we need to find out which can bus messages must be sent, to put my ibooster in fail safe. and it would also be nice to be able to change the braking, sports, relaxation curves. what ibooster can do. I know little about the can bus, but I will still try to connect it to the PC and start studying.
i hope someone can help me.

SOLVED.
I connected the PC. and so I discovered that in order for these iboosters to work, they must be connected to a can bus line with a resistor to terminate. I tried to turn on the car with the can bus disconnected and the brake didn't work, how do I connect the can + wire, the ibooster turns on and does its job. I have now disconnected the ne555 and leave pin20 connected under key as usual.Ibooster send me 3AB can message. I'm happy I fixed it. and I hope to be of help to others.

I bought a ibooster out of a toyota yaris hybrid. The three wire setup that works with the tesla iboosters, does not work on the yaris unit. with the unit connected to a can logger. It works sometimes. When the unit is working it only needs power on the two thick wires. and it does not shutdown.

There are four extra wires, besides the two power wires, the key wire and the two canbus pairs.

Does anybody know what the wires are for? brake switch? brake fluid sensor?

Any help is welkom

Thanks in advance

I have a question to add here. I have a Gen2 booster that came with the plugs, but wires are cut. I know that I can buy entire kits for this but all I need are the connector pins and wire. Does anyone know where I can source just these parts?

Did you check NAPA? They sometimes carry pigtails.

The one near me doesn't have much in the way of that.

If you change your mind about buying the whole kit, pm me. I have a gen2 connector kit which I didn't use and planning on selling.

 

[remy_martian]

Where did you buy the kit?

See linky above. The big 26-pin connector is the same between gen 1 & 2. The 4-pin sensor connector may or may not be... if you post a pic of yours, I can look into it.

Hello.
I want to connect my ibooster to the CANbus. Do you know if it must be the last device on the CANbus or you added termination to it because you only had 2 devices on your network - ibooster and PC?
