I've had this relay in my 599 for years. More reliable than the OEM unit. The heat factor in the 430 is what prompted the unit being built and it works great in the 430. The 599 was made at the same time but with a front mid-engine car and the relay in the trunk, there really is no heat issue. However the unit is solid state as opposed to a simple circuit. I did the upgrade in the 599 and I'm happy with it.
Just change the OEM relay every few years or after any part in F1 fails / get replaced because that probably taxed the relay
The relay is solid state. In the 599 the heat is really not an issue but in the 430 the units got fried from the engine because of its placement. The solid state unit can handle the heat. In our cars it's just an upgrade to a more reliable unit.
I could not feel a faster shift. If it's faster, it's not noticeable. The shifts in Race are very smooth and lightening fast.
Let me add if I can - some of what I will say George mentioned already The unit you mentioned is a solid state relay with some software built ( as an option IIRC) to monitor pump cycles and duration. If it detects an issue will give you some warnings The relay side is different from the relay you have since it is solid state and will not fuse up like any mechanical relay possibly can You asked about benefits : In the 360s and especially the early 430's with the addition of e-diff, the relay and pumps were undersized and the TCU did have as much fail safe programming .. when an issue occured in the system, like a failed accumulator, the pump would run much more often ( like every 20s vs multi mins) causing the relay to work ( cycle ) often and get heated and possibly fuse. Once fused the pump motor will run continuously until it burned out or even worse the pump itself would burn out causing metal flakes in F1 system/fluid. When this happens the repairs can get costly This unit won't fuse since it is solid state and according to them can handle the cycles The F1 system will know any different from this unit from a mechanical unit - no difference at all - 100% The system builds pressure for the f1 system to use and any sub-second difference it the actuation time of pump will not make difference in tank pressure replenishment ... shifting and pumping are two somewhat different subsystems What is the benefit -- insurance / reliability .. if a normal relay fails due to overuse or age you may have costly repairs - this avoid that Later models like 2006 + 430 and 599 etc have relays with more capacity ( more amp handling) so there are a lot less prone to failure especially if you replace every few years .. The key is to listen for pump cycles and other telltale signs of a poorly operating f1 system so you can address an issue that would be a precursor to a failed relay and pump As for George's statement about heat from engine .. not sure about that concern since the relay is in the cabin behind your seat on 360 and 430 - don't think that is an issue I hope I answered any questions - feel free to reach out to me for a call to explain further
