Has anyone installed the Apexi Super Grounding System? It sounds like just the thing to cure the 3K RPM hesitation problem and maybe even the PFC intermittent A/C problem. I was wondering if anyone has tried it? It costs about $170. I am wondering if it is worth a try, as I have a modified Pettit ECU and I am experiencing the 3K RPM hesitation problem. I added some 4 guage wire ground straps and it got better, but it isn't perfect. I still have problems with the A/C on. I am debating trying this kit before I go out and spend hundreds more on a PFC...just to trade hesitation issues for A/C issues.

Thanks,

Jim

Some more info in the Super Grounding System from Apexi's web-site:

Developed using innovative new concepts, the new AfPEX Super Grounding System stabilizes electrical gnoiseh and voltage spikes. The Super Ground System maximizes electrical component efficiency by combining an electrical grounding system with a battery current and voltage stabilization control unit. The control unit features an electrical charging system and electrical noise filter. The double noise filter smoothes turbulent electrical current, providing a stable and consistent voltage flow to all your vehicles electrical devices. The AfPEX Super Grounding System maximizes the efficiency of all factory vehicle electrical systems, allowing smoother engine operation, more efficient electrical component operation, and improved electrical current. The stylish voltage stabilizer box compliments any engine bay with its attractive case design and ominous backlit AfPEX logo.

Features include:

- Effective for high electrical load components by using accumulated stable electricity that has passes through the noise filter.

- This unit cuts electrical spike (noise) produced by the alternator and electrical components. This preserves electrical stability during high load component usage such as air conditioning as well as electrical current loss caused by quick accelerator movement. The A'PEX Super Ground System provides a level of electrical stability never before possible with previous grounding systems.

- Uses a high capacity Double Condensor and Double Noise Filter. Doubling the condenser and noise filter allows the battery to produce a solid and stable voltage current.

- Standard equipped grounding feature. Directly connect the low resistance ground cables from the unit to the alternator and engine head. Electrical components work at maximum efficiency because of the improved electrical current.

- Uses an easy layout, temperature resistant, high conductive 8 sq. OFC cable. The A'PEX Super Ground System uses a high purity OFC cable (non-oxidized copper) Copper wire diameter: 0.12mm X 665 utilizes inter-twined wire.

Max heat resistance: 106 C

Allowable current: 75A

 

I just Installed this kit, but the JDM version with the muffler ground strap. I like it. I'm not sure about the hesitation thing you're talking about, but I know that when I turn my headlights on, it doesn't dim any in my interior at all. It also looks cool. Just a nice mod. At a little UMPH to your engine bay LOL!
