Larini DBW vs alternatives

I hadn’t been aware of alternatives until someone suggested one for the 911

Can anyone throw any light on how the Larini DBW differs from the Sprint Booster or the Racechip XLR pedal box, apart from the Larini being priced like a Maserati part ?

Larini DBW? It's FD I think you'll find.

Snap googling: Both the cheap alternatives do very little other than change the throttle pedal response. In short you get (for example) 100% throttle 'opening' for 80% pedal depression.
Makes everything feel snappier, or you could just save your money and press down on the loud pedal harder.

DWB does that but also tells the TCU that the the revs and throttle opening are different and thereby telling to use the faster shifting map.
Outcome: snappier throttle (pressing harder) and faster shifts.

Not to everyone's taste, apparently.

The cheap ones do what the 3200 does automatically if you don't use WOT, it gradually narrows the band, hence the hair trigger reputation.

Quite right, it’s sold by Larini in the UK so I mistakenly associated it with them. I also googled and found little, FD certainly didn’t want to compare them on the US forums and just said that there’s was made for Maserati ...

Yes FD parts are expensive however they have to spend on R&D on many of these mods and recoup that development money back very slowly as they are working in a niche market with little to no competitors

I've dealt with FD and the guys in the past, and would utterly recommend them :)

Happy to second this comment Chris. Jeff and the guys at FD are top notch.
They couldn't have been more helpful with my enquiries.
I would also add these posts re: "the nature" of the DBW....

My real concern, with the quicker engagement, is whether the car would lurch at take off and/or low speed. Whether about town driving would become more tricky. I guess I would've seen some comment about it if so. Which I haven't.

i don't believe this could be risky. On the one hand the dbw transorms the car, but on the other, it doesn't turn it to an F1 car. So, i believe if your foot has good control of the gas pedal now, you will in the same way learn to handle that.

I believe Mr. Cambio is spot on in his observation. The difference in throttle response is marked but not outrageous.
Previous concerns re: lurching have proven unfounded, indeed, just the opposite. The positive throttle response offers piece of mind.
That said if you are prone to driving like a t*t, or/and are a driving god, then carry on …. nothing to see here.
Otherwise, employing an element of self control, the rewards are well worth the investment.
