    Hello,

    I recently inquired with TPC Racing about developing a suspension module for the 355. I've had two Porsches with their modules and they made a significant improvement in everyday driving and sport/Track driving. So much so that I hope the same concept could be applied to the 355s suspension.

    TPC said they would be willing to look into it but need to understand the type of suspension the 355 has first.

    1. Does the 355 electronic suspension use actuators that have wires that go into the shocks?
    2. Does the suspension actively adjust depending on driving situations or does is set a fixed setting depending on comfort and sport selection with no real time adjusting? (Porsche systems adjust within milliseconds constantly but they have newer technology)

    If this becomes a possibility essentially software programming the 355 suspension module it could end up being better that buying a Fiorano Handling pack ecu and customized suspension maps could be made.
    I think it's worth looking into.

    For reference here is TPCs site: https://www.dscsport.com/?gclid=Cj0KCQiAhc-sBhCEARIsAOVwHuT1zaTBHevaP3x9fYZg142CaYpe-0O8tBfjWoAlJLqkmB7rzMA42_oaAsa3EALw_wcB

    Who here might be interested?

    FHP Ecu is only half the battle. Half of the magic comes from hardware.

    That's just the speed/comfort input into the suspension ECU. There are also acceleration sensors for realtime adjustment of the suspension. Also, there is a brake line pressure switch, presumably for anti-dive under braking. @MoeMonney How do you emulate years of Ferrari R&D with a few test drives/track days?

    F355 (and 348) have anti-dive in the front suspension geometry already.

    Funny to hear all this. My GTB dives and squats like crazy during braking and acceleration. Based on what I see on youtube, my car is typical. 355's are softly sprung.

    1. it has actuators, but they are removable from the shocks.
    2. It's an active suspension that takes into account various inputs, basically it's a 3d map. Here's a decent explanation of it:
    https://deltavee.net/2013/10/manually-adjusting-ferrari-bilstein-active-damping-system/

    There's a simplified diagram in the WSM that shows some of the inputs to display the difference between the comfort and sport suspension settings.

    If something like that were available I'd definitely be interested, but only if it were user tunable and not fixed sport/comfort maps. That could be a minimal adjustment to the factory maps (ie increase or decrease damping up to 20%) etc., but if fixed there wouldn't be too much point.

    I think if you could figure out how to remap the stock control module to FHP mapping, you would have a better business.

    Stock shocks with some more "FHP-like" springs, with the control module remapped would be an easy sell to nearly anyone interested in modifying their 355s suspension.
