HP EFI ECU Harness Kits

Universal V8 Multi-Point Fuel Injection, Includes Bosch 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.

Not my husky's favorite
Size: Large
No bounce, it's too hard and heavy. My husky only uses it once in a while, it is not his favorite thing to chew on.

Better Than Most, But Still No Match for My Super Chewer
This is a decent chew. It’s made of a softer rubber material and has little to no odor, which I appreciate. It’s been about a week, and while it’s still technically in one piece, it’s starting to show some cracks and tiny puncture holes. Now, keep in mind, my 100-lb pit mix Scooby Doo is a full on chew and destroy hound. If it can be chewed, he’ll find a way to shred it to bits. This toy held up longer than a lot of others but still didn’t make the “indestructible” cut in our house. He likes it, but it’s not his top pick, probably why it’s still alive. Overall, it’s a good toy for the price. Probably not for extreme power chewers like Scoob, but it’ll hold up fine for most dogs and give you a little peace and quiet for a while. Do give it a try, Scooby Doo is a chewer in a class of his own, the fact that this has held up past a one 15 minute session is amazing in itself.

Multifunctional dog toy, fetch, chew, dental health
This toy feels like soft rubber, unlike the super hard plastic Size wise, it would be a good toy to toss and play fetch with. My Aussiedoodle took to it right away. It has numerous nubs that are great for dental health. I use it, as well as other toys with nubs, to offer to my pups with a bit of smeared on it, to help with their dental health. 🤗 Thank you so much for taking the time to read this review, have a FANTASTIC day!!😊 5★

Not for aggressive chewers.
Size: Large
Our dog is a 50lb Pit mix. This toy lasted about a week before he took a hole knuckle off. Happy he did not swallow it.
