    Sounds like it's worked well. I would have expected issues with the bias.

    Question

    Hi guys, thank you all for the information shared in this tread. I'd like to ask some questions for those who may be able to answer.

    Has anyone hooked their iBooster brake assist up so as they have assist without engine running? Or were you concerned about flattening battery?
    Is anyone able to confirm the Amperage of the iBooster? And is this current draw closer to linear or exponential as pedal is depressed?? - And/Or relative to torque effort on the pedal/master cylinder??

    Does anyone know if there is software or a means of re-mapping the pedal assist available to us? Obviously the manufacturer of car/model that the iBooster each of us has used will be different in several ways and the iBooster and the assist will be different as a result of the parameters set. Some Tesla's were recalled recently due to poor braking performance and the iBooster's were re-mapped to correct this at the expense of a little reclaimed momentum to recharge their batteries; however, this process might only be hands-on access for Bosch employees and Car manufacturer's technicians at the moment.

    I am thinking about purchasing a generation 2 iBooster as the brake assist is higher, the unit is lighter and the different shape/dimensions are still suitable to my particular chassis. I noted recently that the generation 2 iBooster appears to use a different 4 pin plug, but the larger of the two appears to be the same.
    Does anyone have any experience or remarks on the generation 2 unit? I'm assuming it function just the same in 'standalone' or 'fail-safe' mode as has been pointed out here.

    I'm wondering if anyone has confirmed the terminals and connector part numbers for the generation 2 iBooster? That would be excellent.
    What about a visual pinout out of the main and 4 pin connectors? Any recommendations for wire sizes for particular terminals??

    Any info greatly appreciated, these iBoosters are a real game changer!

    No idea on this one, however, I would assume it is relative to the effort of the assist motor. I used the factory fuse size of 40amps just in case.

    Never heard of this. The only thing I've heard is a change in the amount of regenerative braking on some Tesla models. That came with version 9.0. Nothing to do with iBoosters.

    Additionally, my father owns a 2016 Model X which I bring to service for him, and I have never heard of an iBooster recall.

    Anyways, good luck with the Gen 2 booster!

    I came across some posts on issues with the gen 2 iBooster last night. Seems to be an internal or assembly issue with those ones.
    See: https://www.driveaccord.net/forums/2...dal-noise.html

    As of the date of this post, Honda has recalled and superseded part numbers: 01469-TVA-A23; -A22; -A21; -A20. And the current part number is: 01469-TVA-A24.

    Not sure if these part numbers are recorded on the iBooster gen 2 after it leaves Bosch's assembly plant; but just wanted to let you guys know in case you look at buying one online and it's a dudd!

    Defiantly were issues with how the gen 1 iBooster was operating on the Tesla range; wasn't able to find specifics, because it's Telsa lol
