The Random E46/ZHP Question Thread

[az3579]

Has anyone else tried a sprint booster on a car with a taller diff and tune? I have a 3.38 and shark tune and the sprint booster makes it jumpy to the point that I don't like having it on at all.

Yeah I've tried it on a 3.07 diff car and hated it. The throttle is way too touchy in all modes, and doesn't actually do anything that your foot can't solve by just pressing down on the pedal more.

Definitely not my experience, esp the 'just pressing your foot down'. I get that it's not for everyone, but there is a difference. Ask anyone who's driven my car.

Definitely not my experience either. I really liked it with just the tune and mild diff ratio upgrade. I left it on the second setting

What adhesive did you use to reglue your pillar trim fabric?

I've driven your car, remember?

'Putting your foot down more' is really all the unit does according to all the graphs. It just takes the full pedal range and condenses it to a smaller pedal travel zone. But, its behavior is essentially the same as 'putting your foot down more'.

Here's the proof:

I'd get the kit... you don't want to have to drop the drive shaft twice. That's the same kit I used a couple of months ago
The O2 sensors that matter are at the top og the manifolds and are removed under the hood. The secondary Os sensors are for catalytic converter function and rarely go bad...

Sweet, just figured out what 02’s I’ll be replacing indefinitely then thanks!

And I keep being told by buddy’s of mine that all the hardware can be reused and I’ve read across the E39, M3, and E46F that no one buys new hardware for the Driveshaft or Giubo?

The two things in question in the kit for me are the 1. Threaded Ring & Clamp & 2. Driveshaft Centering Sleeve. Are they really necessary or am I just buying things that they through in the kit for no reason?

Thanks a bunch!

I bought that same kit (or maybe one identical from FCP, I can’t remember), and that centering sleeve is still sitting on my shelf. I’ll have to refresh my memory, but I think those two items don’t apply to our driveshafts?

Regarding the hardware: technically it is single use. I replaced mine because I figured “hey it’s 13 years old, might as well.” I’ve since removed the driveshaft a second time and simply used blue loctite when reattaching.

That’s a good rule of thumb, I’ll keep some blue loctite around for the job. I think I’ll stay with the old hardware in this case
& yeah the two extra items to me seem so silly, Ecs is selling the full kit for 125$, yet FCP if added separately into my cart without hardware has a total of 70$

Didn't say your driveshaft center bearing failed? If that's the case that could of affected the centering bearing. A worn out guibo or center bearing could cause excessive wear on the centering bearing. It would suck if you had a new vibration after getting everything back together...

I'm a believer: I drove Rando's car a couple of years ago. Sprint Booster FTW !
