HP EFI ECU Harness Kits

Universal V8 Multi-Point Fuel Injection, Includes NTK Oxygen Sensor

Overview
Looking for a plug and play alternative for your stock or built late model factory EFI engine? How about a replacement ECU for your older Holley C950? Holley has you covered. HP EFI ECU and harness kits are designed to be used with popular factory EFI engines as an alternative to the factory ECU and harness or as a replacement for your C950 ECU. The HP allows you to accurately control the fuel and ignition of your engine along with additional controls for nitrous, boost or water meth.

ECU is certified to ISO 8846, SAE J1171 United States Coast Guard Requirements for Ignition Protection Fire Resistance. Holley HP EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more I/Os than are available. If more I/Os are required, users should choose the Dominator VMS.
Software and firmware updates can be downloaded here for free.

Awesome quality mouse
Fantastic value. First it feels like a quality mouse and works like a mouse 3-4x the price. It is solid and has nice weight to it, not like some of the flimsy competitors. I am buying another just to have.

Quiet, Comfortable, Convenient
Color: Purple, Color: Purple
I ordered both this mouse and the Proto arc because they are budget friendly and both have good reviews. Not much sets them apart, both are great options! This Seenda is slightly larger which I decided was best for what I need. (Hands 6.5in x 3.5in) Quiet, smooth, similar weight and feel when moving around. Similar control on the screen as well. Both incredibly easy to pair with my Macbook. I ended up choosing this one because I love the colors and I like the knob that turns the volume up and down. They both have buttons that when clicked, go back a page, or go forward a page. I will update my review if it is not durable.

A Smart Upgrade: Seenda’s Ergonomic Mouse Impresses
Color: Blue
As someone who has relied on a traditional wireless mouse for years, I approached the Seenda Ergonomic Mouse with cautious curiosity. I was interested in exploring ergonomic options, but unsure how significant the difference would be. To my surprise, this device made an immediate and positive impression. The mouse is impressively quiet and highly responsive, gliding effortlessly even on a standard desk surface—so much so that I’ve done away with my mousepad altogether. Its ergonomic design provides a natural hand position, which enhances comfort during extended use, especially when browsing or working online. One of the standout features is the inclusion of forward and backward navigation buttons, which streamline web browsing. Additionally, the conveniently placed voice control button on the top of the device adds a modern, user-friendly touch. That said, there are a couple of areas for improvement. While the rechargeable battery is convenient, the mouse does not offer an option for traditional batteries. Furthermore, it appears to lack a clearly visible low battery indicator, which could potentially lead to unexpected downtime. However, I have yet to experience any battery-related issues during use. Overall, the Seenda Ergonomic Mouse is a well-designed and enjoyable tool that significantly enhances the computing experience. It delivers on comfort, functionality, and performance—earning it a strong 4.8 out of 5 in my review.

Amazing mouse! Real wrist saver.
Color: Purple
I do a lots if computer work. This mouse has really relieved the strain on my wrists and hand. It connects via blue tooth or usb remote. Hold a charge for a long time. I usually charge it at least once a month, but sometime I forget and it still works for two, and use it all day long or leave it on. Easy to adapt to. Too knob adjusts volume. Scroll disc on right side and forward back button on left side.
