New booster option for e30 - Bosch iBooster

[hoveringuy]

Has anyone undertaken the project to understand the CAN signals so that the booster response can be adjusted? It's just in fail-safe mode by default.

[nando]

yeah, it's possible to adapt the Gen2 booster to fit the E30 firewall, but not straight forward.

[hozzziii]

Fair enough

2nd Gen bolt pattern is different and not a direct bolt in to the e30

Not sure where preload idea came from. I have no preload on my model s booster and it’s functioned 100%

Hey um, has anyone considered using the second generation iBooster?

This fella:

Used the second generation iBooster from the Model 3.
On the plus side it looks like the MC outputs are on the left, so we can theoretically use the space better.
However the reservoir is tilted, so one would have to swap that.
He also recommends to get the Honda Accord iBooster for 2018 and up cuz it has a remote reservoir. But the MC outputs are on the right, so airbox space might be an issue.

side note: I like his humor, also good info for noobs like me.

Also I can't be sure to confirm the bolt pattern on the firewall.
I found pictures on ebay, just not sure about the size and spacing between bolts.



So yeah, thoughts anyone?

Just posting an update to my on going brake situation.

I am on my 3rd booster (CRV first, Model Y, now Model S). I realized that the booster requires a certain amount of preload on the pedal rod before it works correctly. Unfortunately this causes the brakes to be applied just slightly and get too hot. Ive attempted to back the preload off just slighly but then I have problems with the booster not operating 100% of the time. Its like the travel sensor needs to see the input rod at a certain place before it activates the assist.

Does anyone have any insight on how they setup their pedal?

A couple of pictures from a friend locally who's been driving on the tesla booster for a while!

Finally got the CRV adapter. It does the job perfectly and clears the S54 airbox. My only gripe is that you can’t buy these things new/used very easily. I’m working with a buddy right now to see if we can offer a remote reservoir solution for anyone wanting to pursue this.

You can check out the b-max/fiesta/transit/tourneo reservoir. I got mine a few weeks ago, and can confirm it fits. I got it used though

The CRV-reservoir is 130 dollars from dealer here in Norway. But you get both reservoirs. See picture.

Just curious why not use the CRV adapter?

Just price and availability reasons.

Do you have a part number for this CRV reservoir adapter? How are you utilizing the clutch line since I assume most of these reservoirs dont have that provision?

I do not have a part number but I know it is from a 17-18 CRV. I bought a used master cylinder on eBay that came with the reservoir adapter and reservoir. I removed it from the crv master and put it on the Tesla master.
I ran the hose to a 2002 brake fluid reservoir with 2 outlets, from there a second line goes to the clutch.
I mounted the the reservoir next to the shock tower.

I used a CRV reservoir adapter on my Tesla unit. You can run that to a reservoir of your choice.

I've been running one in my car for a while now, they work great. The pedal sensitivity requires can-bus communication.

I am looking for some alternatives to the crv relocated reservoir, and I might have stumbled on a solution, but have not tested it yet.

Morning iBooster team.

I am looking for a Master Cylinder inlet adapter for the MC so I can run a remote reservoir. I am utilizing this booster with an S54, and the airbox will not allow the factory reservoir to be used. Anyone have any insight?
