I've actually already seen your videos and connector kits. It was seeing the iBooster on your car that gave me the confidence to get one. I've been meaning to contact you to check availability of the connector kits too. Unfortunately not even managed to get my iBooster out the box yet and it's all slipped a bit. Do you have stock of the connectors at the moment? If so I'll get an order placed on your site.seb43654 wrote: ↑Mon Mar 27, 2023 11:46 am Hi Pete, I have a full official CAN .dbc for the smart roadster. Lmk if you want it.
I also installed a iBooster in my roadster for using with openpilot: https://youtu.be/Te4AhlRXnLw
I can give you tips on full install of ibooster if you need to help. Bolt pattern is straight fit. However I used vw e-golf master cylinder instead of tesla one, and theres a few small other hacks you will need to do.
I also sell iBooster's and connector kits on my webstore: https://sghinnovations.com
Very impressed with the work you have done with the openpilot install, both on the reverse engineering of the iBooster command protocol and the conversion of the Roadster steering rack to full openpilot control. Some very nice work there!
Unfortunately my iBooster is the vw version with the 2 stud fixing. I'd be interested to know which one is a direct fit for the Smart (I believe the ally and steel versions of the 4 stud fixing are different dimensions)? If one is a direct fit then I'll try to source one rather than fabricating something.
Re the master cyclinder plan-A is to make up an adaptor to fir the Roadster one, plan-B is to do as you have with the vw cylinder. Reasoning for this is the rear drum brakes, I don't know yet whether the Roadster cylinder has a residual pressure valve built into it and whether one is necessary to keep the rear brake cylinder seals happy, figured sticking with the Roadster one was a safer bet. Interested to hear whether you have had any issues and whether the bore on the vw one gives a good brake feel?
I like your mock up, the model 3 motor looks like it could have been designed to go in there! Interested whether the batteries as drawn will fit without cutting the boot floor? I've been using what appears to be the same 3D model of the subframe (but including the Roadster gearbox, no engine and the same issue with orientation of the damper wrt the RH mount, if it's yours then many thanks for putting it online!) which I've been using to try to estimate battery and motor fit. Unfortunately it doesn't include the boot floor, and I haven't stripped the car yet to take measurements, so don't have a reference for the space envelope available for the battery.seb43654 wrote: ↑Mon Mar 27, 2023 11:46 am Great project very interested in seeing how this goes, and if you are in the UK I would be more than willing to support you in any way necessary... I used to work at ZeroEV and highly considered converting my own roadster multiple times.
I mocked up a tesla model 3 drivetrain with calb modules, which would give a power to weight ratio similar to the new Tesla Plaid...
Hoping to start making some real progress on the car soon. So far just been messing about with bits and pieces while trying to get a few other things sorted but hoping to get it into the workshop and stripped down in the not too distant future
Also thanks for your offer of support, and yes I'm in the UK. It's quite likely I'll be trying to pick your brain when it comes to commissioning the iBooster. The .dbc file would also be very welcome; I think I have figured out most of the bits needed but there's bound to be something I've missed!
