HP EFI ECU Harness Kits

Unterminated Universal Harness, 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.

Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!

Great Value heat gear material with high neck collar and loose fitting
Color: Black, Size: X-Large
My husband has been looking for mock neck shirts that are comparable to UA heat gear material but that are short sleeve and fit loose to wear under his work uniform. These seemed to have been a good soft quality option and the price is is great.

Fit me even better than I was hoping.
Size: XX-Large, Color: Beau Blue
I was all but convinced upon receipt I would be sending these back but they fit beautifully. The trick is understanding what the directions are trying to tell you. I’m 6’4 with a 40 inch waist on traditional jeans (regular fit). I selected 2XL because my feeling was I would want and need a waist line that would fit me but not constrict me. Admittedly my regular fits were getting close to not fitting as good anymore so I felt 2XL would give me that “extra” my regular fits were no longer affording me. Comfortable at the waist(not too tight) and they fit me nicely all over. Perfect length. Colors look great too. The pictures shown are accurate. I’ll be ordering more. Give these a try! Definitely worth the money.

amazing pair of jeans!
Size: XX-Large, Color: Dirty Blue
im 6'2, 280 currently , bought a 38/32 pair of, these jeans and will instantly look forward to buying more, just for comparison , the same day i got these i tried on a pair of levis i had just bought as well, the Levi jeans i got were also 38/32, and they were the 501's which are stretchy, but maaaan, let me tell you, the difference between those and these are night and day, these feel like i can run a mile in them and do whatever activities i choose to, its stretchy in all the right places, the crotch area isnt tight at all, these are incredibly breathable and in comparison to the levi's price , these are cheaper by $15 and they weren't even on sale, unlike the levis which were on sale by 15% and STILL costed $50. Will buy more ASAP. 10/10
