lol, yeah, not to hijack this thread but judging by the condition of the Gen 1 MC (master cylinder) my buddy and I assume that donor vehicle may have suffered a flood, so stay tuned for an iBooster autopsy (let's just say a Dremel may be involved)MattsAwesomeStuff wrote: ↑Thu Nov 24, 2022 8:50 am "Luckily this kit comes with these adapters"

Ahh, good stuff.
I'm now scared of trying my Gen1 after yours crapped the bed.
Fluttering and pulsating seems to be an electrical problem :/
thanks I just bought this kit, Lars did a great job of taking all the guess work out of it, it can really be a pain to identify and track down all the little pins, gaskets, etc.Zapatero wrote: ↑Fri Nov 25, 2022 3:08 pm Just fyi: i hasn't this in my Subaru Impreza conversion. There plug you can buy in the link below, works perfectly well, and all the can code for the Accord ibooster you can find in the code on GitHub of openpilot.

Well, I know I can buy it, but it's $140. I paid $55 for my whole brake booster and master cylinder.

I'm way too cheap to pay $140 for a few wires.
If we knew which ones it was, I presume it's far, far, far cheaper to buy the connectors directly. Hell it might be cheaper from a damned dealership.
You're right, but I see it that way that I'm buying me time not having to put research in it. If it would be listed here by someone what exactly we had to buy, i had done thatMattsAwesomeStuff wrote: ↑Sat Nov 26, 2022 7:26 am Well, I know I can buy it, but it's $140.

let's just say I know a guy who might know a guy so let me see if I can rope him in (for the record he fingered out how to CAN the Gen 1 so not positive it's the same for this guy)Zapatero wrote: ↑Sat Nov 26, 2022 4:42 pm I'm not sure if we really know the can messages to get this ibooster to work? I know it works in Failsafe Mode, but it would be awesome for openpilot cases to know how to control it.
Can someone have a look into this, too?

Edit:
Observations:
SG_ COMPUTER_BRAKE_REQUEST : 29|1@0+ (1,0) [0|0] "" XXX
Computer brake request is ID 232 decimal, 0xE8 hex, the length is 7 bytes.
Specific brake request message starts at position 29 and is 1 bit long - at this point it's clear that this one can only be 1 or 0...
So let's try this one:
SG_ COMPUTER_BRAKE : 39|16@0+ (1,0) [0|0] "" XXX
Computer brake is also in can ID232 with 7 bytes. The specific message starts at position 39 and is 16 bits long, so two bytes. That's a pretty big value but a serious candidate for controlling the ibooster.
Any thoughts on that?
