RE Grounding on digital systems

When an electronic system uses digital logic, it relies on Boolean Algebra to "branch" electronic flow based on the laws of Logic. The short answer is that the path to ground is switched rapidly to control electron flow within the circuit.

When there are various paths to ground, a "Ground Loop" or "Feedback Loop" situation is created. In this situation, a signal seeking a path to ground may travel hundreds of miles within a second of time seeking a path to ground to dissipate.

For this reason, it is crucial for all digital circuits within a subsystem (Car) reference the same ground. Different ground paths create a "difference in ground potential" in which the signal's ground is reached at different times. In the case of the Cruiser, with all the different controllers that are networked to the PCM, precise grounding is crucial; anything added into that networked system (read accessoires: fuel management, engine control, audio, etc.) must reference the same ground used by the network. You will find an entire witring "Bay" at the PCM dedicated to ground for this very reason.

Toasters and hair dryers don't rely on critical ground paths. Digital systems depend on a Precise Ground Path (note the non-plural spelling; as in one path to ground).

To get mpore perspective, talk to someone who does computer networking; specifically UNIX networking via Serial links. If they are worth their salt, they can elaborate (at length) on the need for precise grounding where digital sugnal paths are concerned.

The very short answer: Enhanced Grounding (properly done) can only improve performance, reliability and consistency.

Given that reply, also consider that there is nothing available to the general public that cannot be improperly used, improperly installed, or manufactured from cheaper components to cater to a market share that considers price only as criteria for purchase.

If you do decide to enhance the grounding system, do it properly with quality components using high quality connections and terminating hardware. (This is where the snake oil determination process comes in).

Thanks for the input Dalite. Once I get used the the Stage I performance I might just stop buy SunAutomobile, around the corner from me, and see what they have. The improvement potential sounds logical.

DALITE, Good brain candy. Thank you.

I believe turbo magazine just had a 4 or 5 page review on the different types of grounding systems. One company said that its an easy 12 horses in 5 minutes. My cousin has the jacobs on his 1.8t jetta and it was a noticable differnce in throttle responce engine smoothness.

My set should be here today 8/19/2004. If I get them before 4m on Friday I will test them at the track. Also I will do a Dyno on 9/10/2004. This should be fun. I was told by a guy that was running the whole system that the Hyperground helps from the mid to upper end. Anyway, the concept works because I made a set for myself just to test the concept and I was satisfied with the initial results.

JPMS, how about seeing if SunAuto will offer you a 'group' package? If the price is right I will send you a check for a set, maybe others will also,

When I first talked to them they were reluctant to sell out of the office and refered me to a store. I'll see what I can do. Maybe someone like TThrift could get a jobber price and resell them to us. I would just as soon buy from a PT type than just any store.

I'd buy from Tommy any time.....Also would be interested in a group buy if the price was right.
